Usually involves urgency, frequency, and nocturia (Overactive Bladder Syndrome) - Caused by uninhibited bladder contraction from detrusor muscle hyperactivitiy. - Little PVR; increased contraction on refilling Mixed Incontinence: involuntary loss of urine associated w/ urgency as well as exertion and increased abdominal pressure. (MC type of UI in women) -Caused by detrusor overactivity w/ impaired urethral function Overflow Incontinence: small volume leakage associated w/ a weak urinary stream, dribbling, hesitancy, frequency, and nocturia. -Caused by an incomplete bladder empyting secondary to impaired detrusor contractility or bladder outlet obstruction. (pelvic organ prolapse or enlarged prostate, spinal cord injuries, or bladder neuropathy) - Increased PVR Clinical Work-up Urinalysis and urine culture Post Void Residual (PVR): Determine functional status Hematuria Serum electrolytes (Calcium)- Glucose Ultrasound- Evaluation of hydronephrosis, hydroureter, and most urinary tract stones MRI- Most accurate technique for visualizing pelvic floor defects Treatment: Identify and treat reversible causes. Discontinue potentially offending medications Anticholinergics (if this was the offending factor) Calcium Channel Blockers Underlying medical conditions/Behavioral Approaches Bladder outlet obstruction Diabetes Prostate disease Urinary tract infections Provide a commode or urinal to patients with limited mobility-Useful in Functional Incontinence Pharmacotherapy: - Anticholinergic/Antimuscurinics agents: - Oxybutinin, Tolterodine, Fesoterodine, Trospium, Solifenacin, and Darifenacin - Promote bladder relaxation - Decrease urgency. With behavioral therapy - Alpha adrenergic agonists: MOA- Relax smooth muscle and Decrease urine flow resistance - Selective 1 agents (Prazosin, Alfuzosin) - Long-acting 1 agents (Terazosin, Doxazosin) - Long-acting 1a subtype selective agents (Tamsulosin aka Flomax) –effective for BPH - Estrogens: Little/No evidence to support use - Serotoninergic/Norepinephrine drugs - 5-alpha-reductase inhibitors: Finasteride, Dutasteride Surgical Options: -Electrical stimulation of detrusor muscles - Urinary diversion - Artificial sphincter - Bladder neck elevation - Urethral stricture dilation Hernias: a protrusion, bulge or projection of an organ or a part of an organ through the body wall that normally contains it. Abdominal Hernias: umbilical and epigastric hernias Groin Hernias: o Inguinal: - Indirect inguinal hernia is the most common groin hernia in both sexes. Protrude at the internal inguinal ring. More frequently on the right side in both sexes. - Direct inguinal hernia are more common in men than women and they protrude medial to the inferior epigastric vessels within Hesselbach's triangle, which is formed by the inguinal ligament (Poupart's ligament) inferiorly, the inferior epigastric vessels laterally, and the rectus abdominus muscle medially. o Femoral: less common compared to Inguinal. More common in women than men. Occur later in life than inguinal hernias (usually >70yo). Femoral hernias are located inferior to the inguinal ligament and protrude through the femoral ring, which is medial to the femoral sheath and lateral to the lacunar ligament Hernias are classified by etiology: o Congenital inguinal hernia: due to failure of the processus vaginalis to close. o Acquired Hernias: due to weakening or disruption of the fibromuscular tissues of the body wall allowing intra-abdominal contents to protrude through the acquired defect. Acquired groin hernias can develop as a result of inherent connective tissue abnormalities, chronic abdominal wall injury, or possibly drug effects Treatment: The definitive treatment of all hernias, regardless of their origin or type, is surgical repair. Urgent/emergent repair is indicated for patients who develop complications (eg, bowel obstruction, bowel perforation) related to an inguinal or femoral hernia. Nephrolithiasisspecifically refers to calculi in the kidneys. Geographic Factors - Increased incidence in areas of high humidity and elevated temperatures - Significant increase of incidence during the hot summer months Diet/Lifestyle Factors - Sedentary occupation - High protein, calcium, and salt diet - Oxalate rich foods- Green leafy veggies, nuts, tea, coffee - Frequent use of calcium-containing antacids (i.e. TUMS) - Loop diuretics can lead to increased urinary calcium concentrations - High doses of Vitamin C- Results in hyperoxaluria from ascorbic acid oxidizing into oxalate. Ureterothiasis- specifically refers to calculi in the ureter. These calculi almost always originate in the kidney but become lodged in the ureter. Stones form as a result of growth of crystalline components in a supersaturated urine. Ureteral Stones: - Renal calculi exit the kidney and become lodged in the ureter - Typically lodge at 3 sites:Ureteropelvic junction, Crossing of the ureter over the iliac vessles, and Ureterovesical junction - Stones < 5mm frequently pass spontaneously Types of Urinary Stones: Radiopaque (85%) - Calcium oxalate *most common - Calcium phosphate - Struvite (magnesium ammonium phosphate) Radiolucent - Cystine – smooth edged, ground glass appearance - Uric acid- Most common in children Signs and Symptoms Acute onset of SEVERE unilateral flank pain Remember “Loin to groin distribution” N/V Patients tend to be “on the move” and anxious Stone size does not correlate with severity of symptoms but does relate to the ability of the patient to pass the stone. Diagnostic Evaluation Urinalysis/CBC/Chemistry/ Hematuria and infection Elevated WBC’s = Systemic infection Assessment of renal function Serum Calcium (if elevated, check PTH level) Sodium = Elevated Sodium If history of multiple stones, check PTH level to r/o Hyperparathyroidism 24-hour urine Calcium, Oxalate, and Uric acid levels Imaging studies: - Plain radiograph (KUB) - Renal Ultrasonography - Intravenous pyelogram (IVP) - Helical CT without contrast *Best test Nephrolithiasis Imaging: Non-contrast Helical CT Urogram (preferred, gold standard) - All non-pregnant patients - Preferred over intravenous pyelogram - Findings : Identifies small stones anatomical location and Determines size, shape, and position Imaging: Intravenous Pyelogram (IVP) - Nonpregnant patients where CT is not available - Findings: Functional renal and ureter study and Determines location but not size Abdominal ultrasound - Pregnant patients - Cholecystitis suspected - Gynecologic process suspected - Findings: Hydronephrosis and Renal Stones - Difficult to identify stones < 5mm Abdominal X-Ray (KUB) - History of prior radiopaque stones - Findings: - Radiodense (radiopaque) stones: Calcium Oxalate Stones and Struvite Stones - Intermediate stone lucency : Cystine Stones - Radiolucent stones (not visible on X-Ray): Uric Acid Stones Treatment Guidelines Hydration and Analgesia Maintain adequate circulating volume Opiate analgesia Morphine sulfate Hydromorphone (Dilaudid) NSAIDS: Ketorolac (Toradol) Anti-emetics Metoclopramide (Reglan) Promethazine (Phenergan) Prochlorperazine (Compazine) Medical Expulsive Therapy Off label use of medications: Calcium Channel Blockers and Alpha Blockers Extracorporeal Shock Wave Lithotripsy (ESWL) High energy sound waves break larger stones into pieces so that they will pass more easily Surgery Ureteroscopy Endoscope passed up the ureter for manipulation of the stone Urethral stent placement Percutaneous nephrostolithotomy Fragmentation and removal of large stones from the kidney Hydrocele- collection of serous fluid that results from a defect or irritation in the tunica vaginalis of the scrotum. (less commonly may arise in the spermatic cord) Communicating Hydroceles: Fluid has the ability to move bw the abdomen and the tunica vaginalis in the scrotum. Caused by failed closure of the processes vaginalis. Non-Coummnicating Hydroceles: Serous fluid is contained w/in the tunica vaginalis. Caused by pathologic closure of the processes vaginalis. Varicocele: abnormal dilation of the venous plexus and the internal spermatic vein. CAUSES: Congenital Orchitis or epididymitis Tumors Trauma Radiation therapy Testicular torsion Most hydroceles are asymptomatic and present with an acute painless, enlarged and pearshaped scrotum. Generally located anterior and superior to the testes. Their size can vary with the position of the patient. May become uncomfortable with epididymal irritation. Diagnostic studies Laboratory CBC with differential- Infection or inflammation (? Epididymitis) Urinalysis- Proteinuria or pyuria Imaging Inguinal-Scrotal Ultrasound with Doppler Flow Study Identifies testicular abnormalities (? Solid mass) and assesses perfusion Procedures - Transillumination: Not diagnostic of hydrocele but makes a solid mass less likely. - Hydrocele aspiration: Not therapeutic because fluid reaccumulates quickly. Should produce a clear amber colored fluid Treatment Surgical correction of underlying abnormality is the processes vaginalis BEWARE: - 1. 10% of testicular tumors have a reactive hydrocele. - 2. An inguinal hernia with a loop of bowel in it will transilluminate as well. - 3. Hydroceles are almost NEVER symptomatic. Occur in the left testicle 80-90%, but may be bilateral Pt c/o scrotal pain or a heaviness. Palpated as a “Bag of Worms” which is the twisting and dilation of pampiniform plexus. Diagnostic studies Color flow Doppler Ultrasonography Follow up evaluations with U/S or CT TREATMENT Surgery: No medical therapy is indicated. Significant impairment of sperm production and function is likely. Testicular Torsion: twisted spermatic cord. • Urologic EMERGENCY!! Prompt surgical care w/in 6-12hrs from onset of s/s or infarction will occur Often see in males less than 30 yo May present w/ sudden episode of intermittent testicular pain and 50% of torsions occur during sleep. • • CLINCAL FEATURES: • Acute scrotal pain and edema (< 24 hours) • Nausea and Vomiting • Abdominal pain • Fever • Urinary frequency • High position and transverse lie of affected testicle • Abnormal cremosteric reflex Diagnostic studies: • Laboratory • Urinalysis = normal • CBC = Increased WBC’s • Imaging • Color Doppler Ultrasonography- Consult Urology STAT, then proceed with ultrasound. Balanitis- An inflammation of the glans penis. Treatment: • Urologic consultation and prep for surgery • If seen within first few hours of onset, then manual detorsion can be attempted using an “Open Book” manipulation. Use Doppler u/s once completed to confirm the state of testicular vasculization. In patients with testicular torsion, the affected testis generally is twisted inward (medially). The clinician can easily recall which direction to rotate a torsed testicle (depending on which side is affected) by comparing the action to opening the spine of a book. Causes: Poor hygiene (pediatrics) -Uncircumcised STD’s (adolescents/adults) Candidal Infections (elderly, diabetics) Hx of penile discharge, inability to retract foreskin, difficulty controlling the stream of the urine. Chaffing from lined swim trunks may mimic a balanitis in males. Work-up: H&P- Trauma?STD?DM or immunocompromised? Labs- Serum glucose, culture of penile discharge, syphilis serology, wet mount, KOH for candida, HIV and HPV for populations at risk Treatment: Retract foreskin daily to wash/soak w soap and water Apply bacitracin daily Apply topical Clotrimazole if candida present Evaluate penile/urethral cultures Consider urology consult ***Most common complication is Phimosis (inability to retract distal prepuce over the glans penis) Phimosis- in ability to retract distal prepuce over the glans penis Paraphimosisentrapement of a retracted foreskin behind the coronal sulcus that cannot be reduced. Hair Tourniquets!! Causes: Congential -MC in young children. -Nml into the teenage yrs as long as it does not cause urinary obstruction. Acquired -Caused by poor hygiene, chronic balanitis, or forceful retraction on a congenital phimosis. Treatment: No Tx unless urinary obstruction Proper hygiene If urinary obstruction is present: Surgical Preputial plasty Causes: Uncircumcised Hair tourniquets S/S: Pain, erythema, edema of the uncircumcised penis If constriction is severe, then the edema causes venous engorgement of the glans leading to arterial compromise w subsequent tissue necrosis. Beware of Hair Tourniquets!! Treatment: Emergent Reduction! Noninvasive -Manual reduction Invasive -Puncture technique -Dorsal slit Procedure ***Refer to Urology for circumcision even if reduced. Cystitis Infectious/Inflammatory Conditions Acute Cystitis: Coliform bacteria, gram negatives or gram positive organisms.(E. coli, Staph saprophyticus, other Enterobacteriaceae). S/S: Irritative voiding symptoms (urgency/freq/dysuria), Afebrile, hematuria, suprapubic tenderness or normal exam. Urinalysis: Degree of pyuria/bacteriuria may not correlate with severity of sx. Urine culture is positive: Indicated if recurrent infections or diagnosis in question. DDx: Vulvovaginitis, pelvic inflammatory disease or gyn conditions in females. Urethritis, prostatitis in males. Tx: 1-3 day antibiotics (Fluoroquinolones (Cephalexin 250-500mg q6hrs or Cipro 250500mg q12hrs) and Nitrofurantoin 100mg q12hrs) for uncomplicated acute cystitis. Urinary analgesics for symptom relief. Complicated cystitis should be treated for 7 days Interstitial Cystitis (Painful Bladder Syndrome): • Pain with bladder filling, relieved by emptying. • Irritative voiding symptoms (urgency/freq/dysuria) • Diagnosis of exclusion. Negative w/u. Unknown etiology. • Not common, female>male, hx of bladder problems in childhood. • Cystoscopy may show submucosal hemorrhage with bladder distension (glomerulations). • Spontaneous resolution 50% at 8 months. • TX: No cure.

Epididymitis: inflammation or infection of the epididymis. Commonly affects male 19-40yo. Age dependent pathogens: - Prepubertal males: Escherichia coli-Retrograde extension of bacteria - Males <40 yo: Chlamydia trachomatis (60%) and Neisseria gonorrhoeae - Male >40yo: Escherichia coli- underlying obstructive urinary dz Physical Examination o Gradual scrotal pain and edema o Urinary frequency o Nausea o Fever / Chills o Urethral discharge o Abdominal or flank pain o Patient may waddle o Prehn’s sign = elevation of the affected hemiscrotum above the symphysis pubis improves pain from epididymitis. ** this may be helpful but is not reliable. Diagnostic studies o Laboratory Urinalysis, Urine C&S CBC Urethral discharge culture and wet prep o Imaging Color Doppler Ultrasound (Scrotum) Treatment Must r/o torsion and testicular tumor Bed rest with scrotal elevation/support ABX therapy - Age < 35 yo = Ceftriaxone 250mg IM + Doxy 100mg PO TID x 10-21 days - Age > 35 yo or MSM = Levofloxacin 500mg IV/PO or Cipro 500mg PO BID x 14 days Analgesics Orchitis-inflammatory rxn of the testis secondary to infection. Most cases are associated with a viral mumps infection; however, other viruses and bacteria can cause orchitis. Viral orchitis is associated with the abrupt onset of scrotal pain and swelling and is primarily unilateral. When associated with mumps infection, orchitis generally appears four to seven days after the development of parotitis. STD form in younger age group (<40), associated with urethritis. N. gonorrhea or chlamydia. First affects tail of epididymis, then spreads over body and head of epididymis. Orchitis develops in 20-40% of cases (via direct spread of infection).. May have symptoms of urethritis, irritative voiding symptoms, scrotal pain which may radiate to flank. Fever and scrotal pain evident. May be difficult to differentiate epididymis from testes. Prostate may be tender. Prehn’s Sign: Pain with edididymo-orchitis relieved with elevation above symphysis pubis, not relieved with testicular torsion.. Imaging: Scrotal U/S may be indicated to r/o hydrocoele, torsion. DDx: Tumors (painless), Testicular torsion. Treatment: supportive and should include bed rest and the use of hot or cold packs for pain. Antibacterial medications are not indicated for the treatment of viral orchitis, and most cases of mumps-associated orchitis resolve spontaneously after three to 10 days. Epididymoorchitis requires appropriate antibiotic coverage, as with epididymitis. o Age < 35 yo. N. gonorrhea/Chlamydia: Scrotal elevation, ceftriaxone (Rocephin), a single 250--mg dose intramuscularly, and doxycycline (Vibramycin), 100 mg orally twice daily for 10 days.

F/U urine culture after treatment. • Prognosis: With effective treatment, chronic prostatitis is rare. Chronic Bacterial Prostatis (CBP) Similar organisms/route of infection as acute prostatitis (AP). Previous history of AP risk factor, may have history of UTI, but most have no history of infection. Asymptomatic, varying degrees of irritative voiding symptoms, low back pain, perineal pain are common. Prostate exam may be normal, boggy, or indurated. U/A may be normal. Prostatic secretions show leukocytes (lipid-laden macrophages). Culture is positive. Imaging not indicated. DDx: Chronic urethritis, other prostatitidies, anal disease, other UTI. Tx: Goal is intraprostatic levels (trimethoprim-sulfamethoxazole best cure rate but increasing resistance). Carbenicillin, erythromycin, cephalexin and quinolones also effective. Must treat for 6-12 weeks. Analgesics (antiinflammatories, hot sitz baths). Prognosis: Chronic, difficult to cure, relapses, recurrences are common. Consider longer therapy or suppressive antibiotic therapy. Nonbacterial Prostatitis • Most common of the prostatitidies. • Cause is unknown? (chlamydiae, mycoplasmas, ureaplasmas, viruses) • ? Infectious, noninfectious, autoimmune. • Diagnosis of exclusion. • Same symptoms as CBP.

Diagnostic Evaluation: 1.) PAP Smear ◦ Start screening within 3 years of onset sexual activity or 21 years old ◦ Test yearly until age 30: If 3 consecutive normal PAP, then every 2 – 3 years ◦ Discontinue screening after age 70 if 3 consecutive normal PAP results and no abnormalities in the last 10 years Possible PAP results ◦ Normal – continue routine follow-up ◦ ASC-US – low risk of invasive Ca Repeat PAP at 6 and 12 months Reflex HPV test If either of above abnormal – colposcopy ◦ LSIL, HSIL – colposcopy and biopsy ◦ AGC – colposcopy with endocervical and endometrial evaluation ◦ AIS, adenocarcinoma – may require excisional procedures 2.) Colposcopy -Asc-US and negative HPV screening may f/u in 1yr. -Positive HPV screening should have colposcopy performed. - All pt w/ SIL or atypical glandular cells should undergo colposcopy. 3.) Biopsy Biopsy ◦ In office ◦ Colposcopically directed punch biopsy ◦ Endocervical curettage Neoplastic Disease Bladder Cancer (CMDT 2013) -2nd mc urologic cancer. (M>F) Mean age of dx is 73yo - Risk Factors: Cigarette smoking and Exposure to industrial dyes or solvents - 98% primary bladder cancer are epithelial malignancies, majority being urothelial cell carcinomas. S/S: -Hematuria (gross or microscopic) chronic or intermittent -Irritative voiding symptoms (small percentage) -Abdominal masses may be present on bimanual exams -Hepatomegaly or palpable lymphadenopathy may be present w/ metastatic dz Labs: -Urinalysis reveals microscopic or gross hematuria -Azotemia present in cases w/ ureteral obstruction -Anemia Cytology useful in detecting at initial presentation or to detect recurrence Imaging: -U/S -CT or MRI -Confirmation is done by cystoscopy and biopsy (Transurethral resection) Prostate Cancer (CMDT 2013) Treatment: -Superficial Cancers(Ta, T1)- Complete transurethral resection and selective use of intravesical chemotherapy -Localized, Invasive cancers(T2, T3)- radical cystectomy, irradiation, or combo of chemo and selective surgery or irradiation. -Muscle invasive transitional cell carcinoma (T2 or greater)- neoadjuvant systemic chemo prior to radical cystectomy is superior to radical cystectomy alone. -MC noncutaneous cancer deteted in American men and 2nd leading cause of cancer related death. -Majority of prostate cancers are adenocarcinomas and arise in the periphery of the prostate. -Gleason grading system -Risk factors: Age, dietary fat, AA, family hx. S/S: -Focal nodules or areas of induration w/in prostate during DRE or elevation of PSA -Most often asymptomatic -Rarely: systemic symptoms (wt loss, bone pain) or urinary retention or neurologic symptoms -Lymph node metastases can lead to LE lymphedema - Axial skeleton is the mc site of metastases, pts may present w/ back pain or pathologic fx Diagnostic Evaluation: -Serum tumor markers- PSA is a glycoprotein produced only by cells of benign or malignant of prostate gland. It is useful in detecting and staging prostate cancer, monitoring response to treatment, and detecting recurrence. -PSA>4.0ng/mL: abnormal - PSA< 10ng/mL : typically organ confined - PSA>40ng/mL: advanced dz (seminal vesicle invasion, lymph node involvement, or occult distant metastases) -Digital Rectal Exam -Transrectal Ultrasound-guide biopsy is standard method for detection (not recommended for primary screening) Treatment: -Radiation therapy and radical prostatectomy result in acceptable levels of local control. Prostate CA Screening: DRE and PSA test for men 50yo or older (starting at age 40 for AA) annually Testicular Cancer Wilm’s Tumor Painless, firm testicular mass. May present with mild to moderate pain if tumor is infarcted Patient c/o “heaviness” to the scrotum Often misdiagnosed as epididymitis PEARL: Always consider testicular exam in patients with abdominal mass, chronic cough, resistant to therapy and an unexplained supraclavicular node. NEEDS PROMPT UROLOGY Referral !!! - Metastatic Testicular Cancer Most common renal malignancy in children and the fourth most common childhood cancer. Common congenital anomalies associated with Wilms tumor are cryptorchidism, a double collecting system, horseshoe kidney, and hypospadias A missing iris of the eye (aniridia) and hemihypertrophy are birth defects that is sometimes associated with Wilm’s tumor S/S: • Abdominal pain • Constipation • Fever • General discomfort or uneasiness (malaise) • High blood pressure • Increased growth on only one side of the body • Loss of appetite • Nausea • Swelling in the abdomen (abdominal hernia or mass) • Vomiting A physical examination shows an abdominal mass. High blood pressure may also be present. Tests include: • Renal U/S- initial study • Abdominal CT • Complete blood count (CBC) • Chemistry profile • Urinalysis • Coagulation studies Cytogenetics studies, including 1p and 16q deletion Treatment: - The first step in treatment is to stage the tumor. -Nephrectomy -Chemotherapy and Radiotherapy typically follows surgery. Uterine Fibroids • • The most common benign neoplasm of the female genital tract. Benign growths that occur on the uterus. – Develop from the uterine myometrium and lead to a round, firm and often multiple uterine tumor composed of smooth muscle and connective tissue. – AKA: fibromyomas, leiomyomas, or myomas • Genetic alterations – Many fibroids contain alterations in genes that code for uterine muscle cells. – Hormonal – Excess in Estrogen and Progesterone – Additional substances – Insulin like growth factor may be related to fibroid growth Signs / Symptoms – Asymptomatic to Significantly Symptomatic – Heavy / Prolonged / Irregular menstrual bleeding • Anemia – Dyspareunia – Infertility – Pelvic pain or pressure – Urinary incontinence – Acute ABD/Pelvic pain • Outgrows the available blood supply or ruptures Diagnosis: Most commonly found during routine pelvic exam. – Irregularly shaped uterus or masses, usually non-tender, NOT globular or spherical – Always check serum pregnancy – Transabdominal / Transvaginal Ultrasound: Confirms the diagnosis and determine location and size of the fibroids. – Hysterosonography: TVUS with saline to expand the uterine cavity – Hysteroscopy: Easily performed during an office visit to visualize the walls of the uterus and fallopian tubes Uterine Cancer (Endometrial Cancer) Treatment: Identification, awareness, and watchful waiting. Gonadotropin Releasing Hormone (GnRH) Analogs Depo leuprolide, 3.75 mg IM once monthly can be used preoperatively for 3-4 months to induce reversible hypogonadism, which temporarily reduces the size of myoma, suppresses further growth, and reduces surrounding vascularity prior to surgical intervention. Oral / Injectable Contraception Typical hormonal changes shrinks fibroid tissue Surgical Myomectomy: Removal of fibroids more commonly indicated for patients of childbearing years Hysterectomy Most common GYN malignancy in U.S. 75% are adenocarcinoma 75% have disease confined to uterine corpus @ initial diagnosis - Most common in women 50-70 years old - 30% occur < 40 years old -Suspect HNPCC (Lynch Syndrome)- Colon cancer is the most common with lynch syndrome and the second mc is endometrial cancer however, endometrial cancer will show up first.

RISK Factors Increasing age (most cases between 50-75 y.o) Nulliparity Childbearing in later years of life (40’s) Caucasian Family Hx: BRCA gene - BEWARE of those with personal or family history of Breast CA (male or female relatives) *25% w/BRCA2 gene mutation *45% w/BRCA1 gene mutation *Screening (every 6 months) - Transvaginal US - Ca-125 - Prophylactic oophorectomy by age 35 Breast CA correlates w/ Ovarian CA (Colon CA correlates w/ Endometrial CA) Protective Mechanisms - Oral Contraceptive Pills (OCP’s) - Breastfeeding - Multiparity S/S: Typically asymptomatic -Detected on routine pelvic examination - Note whether the mass is unilateral or bilateral -Premenopausal vs. postmeunopausal -Beware of FIXED masses (doesn’t move) Mild symptoms -Non-specific GI related problems (nausea, change in bowel habits) Advanced Disease -Pain -Bloating (although often vague, pay attention to this symptom when does it occur) Often thru out the day rather than after eating) -Abdominal mass Transperitoneal dissemination is most common route of metastasis. Will often spread to omentum, peritoneum, bowel surfaces, retroperitoneal lymph nodes. Screening: Complete H&P – emphasize pelvic exam Check serum pregnancy CA 125 : >35 units indicates an increased likelihood for a malignant ovarian tumor. NOT a screening test. Transvaginal Ultrasound o Good test for high-risk women o Able to differentiate between benign from malignant ovarian masses. CT ABD/Pelvis Genetic testing (to R/O BRCA) if mass/cancer is confirmed Consider screening examinations for “high-risk” patient populations. o No indications for lower risk patients Diagnostic testing o Laboratory- FSH, LH, Prolactin, TSH, Ca-125 o Imaging- TVUS Treatment: Benign Tumors o Surgical removal of tumor o +/- unilateral oophorectomy Early stage carcinoma o Surgical staging of the disease o Abdominal hysterectomy, bilateral salingo-ooporectomy Selective lymphadenectomy Advanced Disease o Surgical tumor removal o Chemotherapy Prognosis 75% of women are initially diagnosed with advanced disease.

Osmolality = 2(Na) + Glucose/18 + BUN/2.8 nml=285-295mosm/kg Serum Osmolality: - Hypotonic Hyponatremia (<280)-Most causes of hyponatremia - Hypertonic Hyponatremia (>295) - GLUCOSE - Mannitol S/S: Mild: N/V/HA/Lethargy/Disorientation as sodium concentration drops Severe: Respiratory arrest/Seizure/Coma/Permanent brain damage/Brainstem herniation/Death Treatment: • Hypotonic hypovolemic hyponatremia – Normal saline or lactated ringers’ • Hypotonic hypervolemic hyponatremia – Fluid restriction – Diuretics Euvolemic Hyponatremia - SIADH is characterized by: Low sodium Low osmolality Absence of heart, liver, kidney disease Normal TSH and serum cortisol Urine sodium >20 (Natriuresis occurs in response to slight increase in ECV from ADH via increased atrial natriuretic factor and inhibition of renin-angiotensinaldosterone system) Causes of SIADH: • CNS (head trauma, stroke, tumor, infection) • Lung (tumors—esp small cell which synthesizes ADH, infection) • Drugs (seizure meds, anti-depressants, “Ecstasy” • Other (pain, stress, postoperative) Treatment of SIADH: • Water restriction – 0.5 – 1 L per day – Demeclocycline inhibits the effect of ADH on the distal tubule Rate and Degree of Sodium Correction: • Changes in sodium should occur by no more than 1-2 mEq/L/h • Otherwise, can cause changes in brain cell volume, leading to irreversible brain injury, central pontine myelinolysis. Hypernatremia: Sodium concentration >145mEq/L • • • • • • Changes in sodium are due to water imbalance, not sodium. Most cases of hypernatremia are due to inadequate water intake (THIRST) Urine osmol helps differentiate renal from nonrenal water lost. Low urine osm is characteristic of low ADH activity, hence diabetes insipidus Urine Osm >400 implies high ADH and that renal water conserving ability is functioning. Urine Osm <250 implies low ADH and is characteristic of central and nephrogenic diabetes insipidus (seen with Lithium or demeclocycline therapy) S/S: Dehydrated= Orthostatic hypotension and Oliguria Early signs: lethargy, irritability and weakness Late signs: Hyperthermia, delirium, seizures,, and coma Treatment: • Hypernatremia w/ hypovolemia= isotonic .9% NS • Hypernatremia w/ euvolemia= water ingestion or IV 5% dextrose • Hypernatremia w/ hypervolemia= 5% dextroseor Loop diuretics to promote natriuresis and lower Total Body Sodium • Changes in sodium should occur by no more than 0.5-1 mEq/L/h or 12 mEq per day • Remember the brain synthesizes idiogenic osmoles in response to hypernatremia so if serum sodium is corrected too rapidly, water will shift into brain cells and cause edema Hypokalemia Calculate free water deficit: Vol to replace (L) = TBW x (Na-140)/140 TBW men = .6 (Ideal body weight) TBW women = .5 (Ideal body weight) • Total body content = 50 meq/kg • More than 95% intracellular • K level kept in very narrow range by cellular shift and renal handling • Abnormal potassium levels lead to life-threatening arrhythmias • Magnesium is a cofactor for potassium uptake and should always be checked in setting of hypokalemia Symptoms: • muscle weakness, muscle cramps, rhabdomyolysis, arrhythmia, ileus • ECG U waves, PVC, depressed ST • Hypokalemia can worsen digitalis toxicity because of its depressive effect on the Na-K ATPase pump. 3 Main mechanisms: • Intracellular shifts (insulin,alkalosis,trauma,periodic paralysis) • Renal loss (aldosteronism, Cushing’s, genetic disorders- High urine K (> 40) means renal losses -Aldosterone -Bartter’s syndrome -Liddle’s syndrome • Extrarenal loss (diarrhea, vomiting, laxative abuse, villous adenoma)- Low urine K (<20) extrarenal losses Treatment: • For severe hypokalemia or EKG changes move patient to a monitored bed. • Know patient’s GFR!—decrease replacement doses in renal disease. IF GFR is normal, generally expect to replace 10mEq per 0.1 decrease in potassium. • Oral K supplementation is the safest for mild to modereate deficiency. • Avoid glucose-containing fluid to prevent further shifts of K into the cells. • Mg deficit should be corrected HyperKalemia: Serum Potassium level >5.0mEq/L (5.0mmol/L) Causes: Spurious causes of hyperkalemia: o Hemolysis o Thrombocytosis o Leukocytosis o Repeated fist clenching o Drawn above IV site where potassium is infusing Renal failure Medications (heparin, ACE, ARB, aldactone, trimethoprim, NSAIDs, cyclosporine, tacrolimus Cellular shifts (acidosis, rhabdomyolysis, internal bleeding, vigorous exercise) S/S: Muscle weakness, flaccid paralysis, ileus ECG: bradycardia, PR interval prolongation, peaked T waves, QRS widening, and biphasic QRS-T complexes. BBB and AV block. VFib and Cardiac arrest. Treatment: • IF EKG changes (peaked T waves, widened QRS) give calcium to stabilize cardiac membrane. • Give diuretics and resin binders to remove potassium from body. • Give Insulin, albuterol, bicarbonate for quick onset of action to cause cellular shifts. • If medically refractory, dialysis. Hypocalcemia: Serum Ca conc <8.5mg/dL • • • • • Interpret abnormal calcium levels with phosphorus, Vit D, magnesium, and PTH levels Hypocalcemia can cause arrhythmia and tetany The mc cause is renal failure(CKD), due to decreased production of vitamin D and hyperphosphatemia. Low magnesium reduces the release of PTH, causing hypocalcemia. Respiratory alkalosis, total calcium is normal, but the ionized calcium is low. S/S: Spasm of skeletal muscle causes cramps and tetany Convulsions, perioral and peripheral paresthesias, and abdominal pain Chvostek’s sign- Contraction of the facial muscle in response to tapping on the facial n anterior to the ear Trousseau’s sign- Carpal spasm after occlusion of the brachial artery w/ a BP cuff ECG shows long QT. Treatment: Asymptomatic Hypocalcemia: Oral calcium carbonate (1-2g) and Vit D Severe: IV calcium gluconate Hypercalcemia Causes: Outpatient- primary hyperparathyroidism. Inpatient- malignancy via production of PTH-rp (esp lung, breast, kidney,hematologic, thyroid) Others (familial hypocalciuric hypercalcemia, meds such as HCTZ, Paget’s, milk-alkali syndrome) • Hypercalciuria uslaly precedes hypercalcemia • • • Symptoms: neurological changes-drowisiness, weakness, depression, stupor, coma GI manifestations-constipation, polyuria ECG shows short QT interval. Measurement of PTH and PTHrp distinguish between malignancy-associated hypercalcemia and hyperparathyroidism. Treatment: • Volume repletion is first line to increase calcium excretion. • Bisphosphonates cannot be used in renal insufficiency, but are the mainstay of treatment for hypercalcemia of malignancy. (May take up to 72 hours for effect) • Dialysis can be used to lower calcium when levels are as high as 18-20 Hypomagnesemia Metabolic Acidosis AG= Na+ - (Cl- + CO2-) Serum concentration of Mg may not be decreased even in the presence of Mg depletion. Check urinary Mg excretion if renal Mg wasting is suspected. Causes: Diminished absorption or intake: Alcohoism, PPI, laxative abuse Increased renal loss (diuretic therapy, hyperaldosteronism) DM Post-parathyroidectomy (hungry bone syndrome) Respiratory alkalosis Pregnancy S/S: Similar to hypokalemia and hypocalcemia Weakness and muscle cramps Neuromuscular and CNS hyperirritability – tremors, athetoid movements, jerking, nystagmus, Babinski response, confusion, and disorientation Cardiovascular response: HTN, tachycardia, Ventricular arrhythmias Treatment: Chronic hypomagnesium: Magnesium oxide 250-500mg orally OD or BID Symptomatic hypomagnesemia: IV Magnesium sulfate 1-2g over 5-60mins mixed in either dextrose or 0.9%NS Torsades de pointes- 1-2g MgSO4 in 10mL dextrose 5% solution pushed IV over 15mins Low HCO3- with low pH Normal Anion Gap Acidosis: AG<12 - GI losses (diarrhea) - Renal tubular acidosis (defect in renal acidification) Treatment: - Administration of alkali (either as bicarbonate or citrate) to correct metabolic abnml and prevent nephrocalcinosis and CKD -Thiazides may reduce amount of alkali required but could cause hypokalemia -Potassium supplement Increased Anion Gap Acidosis: AG>12 Methanol Uremia Diabetic Ketoacidosis (DKA) Paradelhyde or Propylene Glycol Isoniazid, infection Lactic acidosis Ethylene glycol Salicylates Treatment: -Tx aimed at underlying disorder, such as insulin and fluid therapy for DM and appropriate volume resuscitation to restore tissue perfusion. Metabolic Alkalosis High HCO3- and High pH Check urinary chloride concentration to differentiate saline-responsive alkalosis from salineunresponsive alkalosis. -Saline-responsive alkalosis(more common): extracellular volume contraction -Diuretic therapy, Posthypercapnia, Vomitting or NG suction, Antacids, Transfusion, Contraction alkalosis Treatment: - Correction of the extracellular volume deficit with isotonic saline. - Discontinue diuretics. - H2-blockers or proton pump inhibitors may be helpful in pts w/ alkalosis from NG sunction. - Acetazolaminde will increase renal bicarbonate exrection (risk of hypokalemia). -Saline-unrespoinsive alkalosis implies excessive total body bicarbonate w/ either euvolumeia or hypervolemia - Bartter syndrome (renal salt wasting), Primary hyperaldosteronism, Hypercalcemia and hypoparathyroidism, Severe potassium depletion, Liddle syndrome, Exogenous alkali, Exogenous minerlocorticoids, Licorice Treatment: -Surgical removal of mineralocorticoid-producing tumor and blockage of aldosterone effect w/ ACEi or spironolactone. - Metabolic alkalosis in primary aldosteronism can be treated only w/ potassium repletion. Respiratory Acidosis (Hypercapnia) S/S: Respiratory Alkalosis High PCO2 and low pH Results from hypoventilation and subsequent hypercapnia. Acute respiratory failure associated w/ severe acidosis and only small increase in the plasma bicarbonate. Chronic respiratory acidosis seen in pts w/ underlying lung dz, such as COPD. Acute onset: somnolence, confusion, mental status changes, asterixis and myoclonus. Severe: increased cerebral blood flow, CSF and intracranial pressure. Papilledema and pseudotumor cerebri. Treatment: -Relieve underlying disorder to improve ventilation -IV naloxone administered for Opiod overdose Low PCO2 and High pH Causes: Hyperventilation syndrome Bacterial Septicemia Cirrhosis Pregnancy (progesterone stimulates respiratory center) S/S: Acute: light-headedness, anxiety, perioral numbness, and paresthesias. Severe: Tetany from low ionized calcium, since severe alkalosis increases calcium binding to albumin. Treatment: Hyperventilation from anxiety: Discourage from breathing into a bag bc it doesn’t correct pCO2 and may decrease pO2. Reassurance and sedation if hyperventilation persist.
