A 12 or 24 hr specimen?? Renal Function Tests: Table 43-4 BUN (Bld urea nitrogen) (table 43-4) Urea forms in the liver, along with CO2, constitutes the final product of protein metabolism. The amount of excreted urea varies directly with dietary protein intake. The test for BUN which measures the nitrogen portion of urea is used as an index of glomerular function in the production & excretion of urea. Thus, serves as an index of renal functioning. A marked increase in BUN = severe impaired renal function Adult: 7-18 mg/dl or 2.5-6.4 mmol/L Elderly 8-20 mg/dl or 2.9-7.5 mmol/L Child 5-18 mg/dl or 1.8-6.4 mmol/L Urine Creatinine (table 43-4) Amino acid waste product derived from muscle creatine (a product of protein metabolism) All creatinine filtered by kidneys in a certain timeframe goes into the urine, creatinine levels thus are equal to the glomerular filtration rate. Disorders of kidney interfere with normal secretion of creatinine Thus creatinine measures effectiveness of renal functioning (serum Creatinine) Keep in mind that rate normally decreases as we age urine creatinine men 0.8 -1.8 g/24h urine creatinine women 0.6 - 1.6 g/24h blood creatinine: 0.4-1.5 mg/dl Renal Function Tests: Table 43-4 Creatinine Clearance Decreased Impaired kidney function Kidney Disease Shock & dehydration COPD CHF Increased State of high cardiac output Pregnancy Burns Carbon monoxide poisoning What causes them?

Condom Drainage and Leg Bag Urethritis Inflammation of the urethra Commonly associated with STIs (gonorrhea, chlamydia), feminine hygiene products, scented toilet paper, spermicidal jellies S & S include pain & pyuria Management includes removing the cause, antibiotics (if bacterial) and drinking plenty of fluids, use of lubricants with intercourse, teaching re STI Pyelonephritis Is a bacterial infection causing inflammation of the renal pelvis, tubules, and interstitial tissue of one or both kidneys. Common cause is E. coli May also be caused by candidiasis. May be acute Usually enlarged kidney, maybe abscesses, & possibly destruction of glomeruli May be chronic Kidneys scarred, contracted, & nonfunctioning Acute Pyelonephritis Clinical manifestations Appears acutely ill Fever, chills, flank pain, nausea, headache, muscle pain, dysuria, urgency, frequency Urine cloudy, bloody, foul smelling, increased WBC & casts Diagnosis Ultrasound or CT to check for obstruction Urine C & S X-ray (KUB), MRI Acute Pyelonephritis Medical management May be outpatient or inpatient treatment Antibiotic therapy based on C & S, usually for 7-10 days, up to 2 weeks for outpatients Analgesics Follow up urine C&S 2 weeks after completing therapy Chronic Pyelonephritis Likely to occur after repeat acute bouts of Acute Progressive with recurrent attacks Clinical Manifestations No symptoms of infection , unless acute exacerbation May have fatigue, headache, poor appetite, polyuria, excessive thirst, weight loss Lab values are abnormal Complications ESRD, Hypertension, Renal calculi Chronic Pyelonephritis Medical management Goal is prevention of further renal damage Antibiotics - cautious use depending on degree of renal function High fluid intake may be contra-indicated Control hypertension Chronic pyelonephritis Nursing care Monitor fluid balance, may require IV fluids (nausea, IV antibiotics) Monitor blood work Address pain: analgesic & 3-4L fluids unless contraindicated ? V/S – T q4h Bedrest Client education Follow-up urine cultures Appropriate use of antibiotics Perineal hygiene Acidification of urine by drinking cranberry juice or taking ascorbic acid Frequent emptying of bladder Adequate fluid intake Early detection of infection Primary Glomerular Diseases Definition: “a group of kidney diseases caused by inflammation of the capillary loops in the glomeruli of the kidney” (Hogan & Maydayag, 2004) Caused by an immunologic reaction to an antigen, causing inflammatory response that damages the glomeruli IgG can be found in glomerular capillary walls Often preceded by group B hemolytic strep infection Primary presenting feature is hematuria Includes: acute & chronic glomerulonephritis, rapidly progressive glomerulonephritis, & nephrotic syndrome Manifestations: proteinuria, hematuria, decreased GFR, alterations in sodium excretion Acute Glomerulonephritis Primarily in children over 2, but can occur at any age Most cases preceded 2-3 weeks by group A strep infection of throat May follow impetigo or viral infections Medications or other foreign substances may cause Group A Streptococcus Occasionally, autoimmune Clinical Manifestations Hematuria – may be micro or macroscopic Urine may be cola coloured due to RBC casts Proteinuria - albuminuria, Headache, malaise, flank pain in severe form Tenderness over CVA Elderly may experience circulatory overload Some edema & hypertension in 75% Atypical: confusion, somnolence, seizures Diagnostics & Assessment May require renal biopsy Poststreptococcal – usually elevated serum antistreptolysin O or anti-DNase B titres Over half have elevated serum IgA & normal complement About 70% of adults recover Complications Hypertensive encephalopathy - therapy aimed at decreasing blood pressure without impacting renal function Heart failure Pulmonary edema Optic neuropathy - rare Medical treatment Treat symptoms Preserve kidney function Prevent complications Drugs for cause & symptoms Restrict protein with elevated BUN Restrict sodium as necessary Nursing Management Most uncomplicated are treated at home High carbohydrates Fluid replacement as per losses & body weight – remember insensible loss Usually diuresis begins 1 week after onset Client education – fluid/diet restrictions, aware of symptoms of renal failure, S&S infection, medication knowledge Follow up assessments Medical management Reduce inflammation Plasmapheresis in conjunction with corticosteroids & immunosuppressive agents Antibiotic therapy Dialysis Chronic Glomerulonephritis May be due to repeated episodes of acute Hypertensive nephrosclerosis Hyperlipidemia Chronic tubulointerstitial injury Hemodynamically mediated glomerular sclerosis Kidneys shrink, surface rough & irregular, glomeruli & tubules scarred, branches of renal artery thickened Results in ESRD Clinical Manifestations Some may have no symptoms for many years and may be secondary diagnosis Malaise, weight loss, edema, increasing irritability, nocturia (kidney’s inability to concentrate urine), headache, dizziness and digestive disturbances Edema increases as heart failure increases & serum albumin decreases Severe anemia S&S of renal insufficiency & chronic renal failure as disease progresses Peripheral neuropathy & neurosensory changes Diagnostics & Assessment Many lab abnormalities as GFR decreases CXR cardiac enlargement & pulmonary edema EKG may be normal or abnormal Chronic Glomerulonephritis Medical Management Reduce inflammation Plasmapheresis in conjunction with corticosteroids & immunosuppressive agents.

Large amt protein in urine & low serum albumin Nephrotic Syndrome Goal of treatment is to preserve renal function Maintain fluid/electrolyte balance: weight QD, girth measurements, intake/output Loop diuretics (Lasix) – use caution Plasma volume expanders such as albumin, dextran, plasma to increase oncotic pressure Mild sodium restriction Good skin care (edema disrupts cellular nutrition) Steroid therapy & anticoagulants (reduce inflammation & prevent renal vein thrombosis) – especially if infection High protein, low sodium, high potassium, low saturated fat diet Education Nursing Care: Priority Diagnoses Fluid volume excess Altered nutrition: less than body requirements Risk for impaired skin integrity Risk for infection Fatigue Knowledge of therapeutic regimen Renal Transplantation Organ Donation Preoperative Management Postoperative Management Immunosuppressive therapy Rejection Infection Urinary Function Complications Renal Transplantation URINARY CALCULI Urinary calculi (urolithiasis) Form primarily in the kidney (nephrolithiasis) but can form or migrate to lower urinary system. Usually asymptomatic until they pass into lower tract. Primary causes are 1) urinary stasis, 2) supersaturation of urine with poorly soluble crystalloids (leads to precipitation of crystals). Risk factors Infections Dehydration High mineral content in water Prolonged indwelling catheterization Neurogenic bladder Previous history Foreign bodies Failure to empty bladder completely Metabolic disorders (I.e. hypercalcemia) Obstruction in urinary tract Female genital mutilation Abnormalities of Urine Sediment in Client With Renal Calculi ABNORMALITY Red cells White cells Protein Pus + bacteria SIGNIFICANCE Suggests injury to urinary tract suggests inflammation or infection Suggest glomerular injury Infection Types of Stones Calcium, Oxalate, Struvite, Uric acid, Cystine Manifestations Severe sharp pain Renal colic flank pain on side of affected kidney radiating to groin May have nausea, vomiting, pallor, grunting respirations, elevated BP, pulse, diaphoresis & anxiety Elevated WBC & temp Calculi Staghorn Calculis Medical Management Increase fluids Reduce pain Prevent stone recurrence Dietary changes – see next slide Medications Surgery Nursing Management Pain Impaired urinary elimination Effective management of therapeutic regimen Risk for infection Urinary retention KIDNEY STONES & PAIN OPIODS NSAIDs ANTISPASMODICS RELAXATION IMAGERY THERAPEUTIC/HEALING TOUCH BREATHING TECHNIQUES Surgery Lithotripsy: laser and ESWL Nephroscopic removal Pyelolithotomy Nephrolithotomy Lithotripsy Extracorporeal Shock Wave Lithotripsy Nephroscopic Removal of Kidney Stones Pyelolithotomy Removal of Kidney Stones Nephrolithotomy Removal of Kidney Stones to the Urinary Tract Bladder Trauma blunt or penetrating injury to bladder that may cause bladder rupture. Often the result of car accidents, seat belt pressure against distended bladder. Urine spills into peritoneal cavity, causing peritonitis & pelvic cellulitis. Manifestations: hematuria, pain, difficulty voiding. Usually require surgery, post-op have a urethral or suprapubic catheter. Ureteral trauma usually the result of surgical accident. Other causes gunshot or stabbing Symptoms include flank pain, hematuria, eventually paralytic ileus, sepsis Treatment is surgical repair Urethral trauma • May result from pelvic fracture (falling on object such as bar on bike) •Symptoms include inability to void or altered stream, swelling in groin, scrotum or inguinal area, may lead to sepsis and necrosis. •Complications include urethral strictures or impotence in men. •Treatment may be medical (catheter for several weeks or surgery) Renal trauma Renal Trauma Traffic accidents & falls most common cause Five categories Complications include hemorrhage, abscess, fistula, HT Treatment may be medical or surgical- watch & see Manifestations: Type of injury is key May have hematuria, shock, flank pain, palpable mass, paralytic ileus, bruising over flank Renal Cancer 85% of renal tumors are malignant Most common between ages of 50 and 70 Cause unknown but some links between chemicals and cancer, I.e. smoking, exposure to lead. Tumor starts in renal cortex and lead to obstruction, renal failure, hemorrhage invasion of surrounding tissue Symptoms: painless hematuria, flank pain, palpable mass (often delayed diagnosis – 35% have mets when diagnosed) Renal cell carcinoma with venous invasion. Stage I: confined to kidney capsule; survival rate 65% Stage II: extends beyond capsule into fatty tissue; S.R 40% Stage III: regional lymph nodes, renal vein, possibly IVC Stage IV: distant mets, often lungs & mediastinum Survival rare in III and IV Management Surgery: partial or radical nephrectomy is usual treatment Radiation therapy: with chemotherapy and/or surgery. Pre-op to shrink tumor or post-op for residual cells or mets Chemotherapy: seems to be less effective b/c of slow growth rate. Vinblastine is most effective single agent with response rate of 25% Immunotherapy: fairly new, stimulates immune system Renal surgery Nursing Management Pre-op teaching and emotional support Post-op there is high risk for hemorrhage, monitor for signs of bleeding (may be incisional or internal). Also risk for pneumothorax. Post-op care requires: DB & C (how can you help??) Monitor urine output Pain Management Monitor GI status (watch for ileus) Bladder Cancer Appears to be the result of exposure of bladder wall to carcinogens – smoking, asbestos, radiation & chemo Gross hematuria is often the first sign. Identified through cystoscopy, IVP, CT, MRI, blood work (CEA) Treatment includes surgery, radiation therapy and chemo Just read on own Cystoscopy Surgery Transurethral resection, partial cystectomy, radical cystectomy & urinary diversion Urinary diversion procedures: Ileal conduit Indiana pouch Neobladder Palliative procedures: percutaneous nephrostomy or pyelostomy (tube in renal pelvis), ureterostomy Indiana Pouch Procedure Indiana Pouch Urine is removed by inserting a thin tube (catheter) into the stoma when the pouch is full. A bag is not required and the patient simply wears a bandage over the stoma. The patient is then taught to catheterize the reservoir to drain urine at regular intervals during the day. Hypertension May be cause of renal failure or effect e.g. Renal artery stenosis decreases blood flow to the kidney. This activates the renin-angiotensinaldosterone system which increases BP. Renal hypertension results from the kidney’s inability to excrete salt and water. Sustained high BP causes nephrosclerosis & damages arteries and arterioles Renal vascular disorders Renal artery disease Renal vein disease Congenital Abnormalities May involve abnormalities in number, position or size. Agenesis: means absence of one or both kidneys Sizes: small with or without functioning tissue Horseshoe kidney: both kidneys are joined, in lower lumbar region Susceptible to hydronephrosis, infection and calculus formation Polycystic Kidneys Hereditary disease characterized by cyst formation & massive enlargement – affects both adults & children. Disease is slow & progressive results in CRF No cure so management is conservative, supportive medical treatment Eventually needs dialysis or transplant Renal Transplantation Renal Transplantation Organ Donation Preoperative Management Postoperative Management Immunosuppressive therapy Rejection Infection Urinary Function Complications Renal disorder website http://www.merck.com/mmhe/sec 11.html
