WEEK 17: Urological system - History Upper GU tract=kidneys, renal pelvis and ureter Lower GU tract=bladder, urethra, prostate, genetalia Functions: kidney(Ca2+; BP, EPO, H2O balance); bladder(storage+excrete urine); prostate+seminal vesicles(semen); urethra(urine+ejaculate conduit) PC: Pain (voiding, loin, abdominal); Lethargy/malaise; Increased micturition; Incontinence; Oedema; SOB; Temp/rigor; Hyper/hypotension; Discharge(urethra); Proteinuria/haematuria/pyuria; Abnormal blood results (U & E’s); Anorexia /dimished appetite Condition Pain Lower urinary tract symptoms Symptoms Pain due to acute inflammation of the bladder or urethra is called dysuria SOCRATES Pain may arise from: 1. The kidney (loin pain) Renal angle (between the 12th rib and the spine) or loin pain is due to stretching of the renal capsule or renal pelvis. Causes=infection(constant loin pain, with systemic upset, fever, rigors and pain on voiding suggests infection of the upper urinary tract and kidney (acute pyelonephritis); inflammation(chronic dull, aching loin discomfort may occur with chronic renal infection and scarring from vesico-ureteric reflux, adult polycystic kidney disease (APKD) or chronic urinary tract obstruction) or mechanical obstruction(chronic obstruction may be painfree. Dull, non-localized pain occurs in renal stone disease and some forms of glomerulonephritis, e.g. IgA nephropathy, and can mimic musculoskeletal conditions). 2. The ureter (ureteric colic) (loin to groin pain) Caused by acute obstruction with distension of the renal pelvis and ureter by a stone, blood clot or, rarely, a necrotic renal papilla. The pain is of sudden onset, severe and sustained(colicky), and may radiate to the iliac fossa, the groin and the genitalia, especially the testis. The patient is restless and nauseated, and often vomits. Once the obstructing pathology reaches the bladder, symptoms may resolve. 3. The bladder (suprapubic, constant pain or pain on passing urine - voiding) Voiding pain (dysuria) is pain during or immediately after passing urine, often described as a 'burning' sensation felt at the urethral meatus or suprapubically and associated with a desire to pass urine more often (frequency). Boxer short distribution of pain. The most common cause is infection and/or inflammation of the bladder (cystitis). 4. Prostate Prostatitis and urethritis produce similar symptoms. Prostatitis causes perineal/rectal pain. Pain localized to the penis indicates local pathology, such as stricture, stone or, rarely, tumour. Causes retention of urine. 5. Penile/erectile deformity/testicular Testicular and epididymal pain may be felt primarily in the groin and lower abdomen. Distinguish tenderness and swelling of the testis from a strangulated hernia or acute epididymo-orchitis; in pubertal boys and young men consider torsion of the testis, which is an emergency. 1. Storage symptoms/irritative (females usually eg cystitis) Symptoms are ‘FUN’ Frequency is increased micturition with no increase in the total urine output Urgency is a sudden strong need to pass urine and may cause incontinence if there is no opportunity to urinate. Urgency is due either to overactivity in the detrusor muscle or abnormal stretch receptor activity from the bladder Nocturia means being wakened at night to void. Storage symptoms are usually associated with bladder, prostate or urethral problems, e.g. lower urinary tract infection, tumour, urinary stones or urinary tract obstruction, or are a consequence of neurological disease 2. Voiding/obstructive phase symptoms (males usually) Hesitancy is difficulty or delay in initiating urine flow. In men over 40 this is commonly due to bladder outlet obstruction by prostatic enlargement. In women these symptoms suggest urethral obstruction due to stenosis or genital prolapse. Pt normally has slow or intermittent flow, strains abdominals to increase abdo pressure, has terminal dribbling and may even double void due to incomplete emptying(try once, then go back five mins later) 3. After micturition (effects of 1 and 2 combined = detrussor problem) Dribbling and incomplete emptying are caused by obstruction but, with associated storage symptoms, indicate abnormalities of detrusor function. 4. Urinary incontinence: points to cover in the history Age at onset and frequency of wetting Ever dry at night? Occurrence during sleep (enuresis) Number of pads used. Are they damp, wet or soaked? Any other urinary symptoms Provocative factors, e.g. coughing, sneezing, exercising (suggest stress-induced incontinence) Past medical, obstetric and surgical histories Impact on daily living Causes of urinary incontinence: Degenerative brain diseases and stroke; Spinal cord damage; Neurological diseases, e.g. multiple sclerosis; Pelvic floor weakness following childbirth; Bladder outlet obstruction; Urinary tract infection; pelvic surgery or radiotherapy; Stress – physical activity, coughing, sneezing – increased abdo pressure+effects on bladder Urge – bladder spasms = UTI/hyperactive detrussor muscle Mixed Overflow – dry during day but wet at night Functional assessment methods of lower urinary tract function Frequency/volume chart Use to monitor micturition patterns, including nocturia, and fluid intake The patient collects his/her urine, measures each void, and charts it against time over 3-5 days Urine flow rate The patient voids into a special receptacle that measures the rate of urine passage A low flow does not differentiate between poor detrusor contractility and bladder outlet obstruction – determine using invasive tests and filling studies Urodynamic tests Invasive tests, necessitating insertion of bladder and rectal catheters to measure total bladder pressure and abdominal pressure and to allow bladder filling Filling studies determine detrusor activity and compliance o Low detrusor pressures with low urine flow suggest detrusor function problems o High detrusor pressures with a low flow suggest bladder outlet obstruction Sexual dysfunction Erectile dysfunction = inability to obtain/maintain erection for satisfactory intercourse(diabetes) Premature ejaculation = avg time is 3 mins!; may have performance anxiety Haematuria CYSTITIS Dysuria associated urinary frequency, urgency of micturition with occasional 'urge incontinence'; haematuria; these are typical symptoms of lower urinary tract infection 1. How much/what does it look like: clots/debris/mucus? Microscopic (detected on urinalysis) is a common feature of renal or urinary tract disease, especially if associated with proteinuria, hypertension, raised serum creatinine or reduced estimated glomerular filtration rate (eGFR). It may be a solitary and benign finding if these are all normal. Small quantities of blood give the urine a 'smoky appearance’ Macroscopic/frank (visible to the naked eye). Larger quantities make the urine brown or red 2. When: start of stream = urethral problem entire stream = bladder/UT disease end of stream = prostate problem Haematuria = malignancy until proven otherwise 3. Ass symptoms: pain, fever, trauma, exercise. Distinguish haematuria from contamination of the urine during menstruation. Confirm haematuria by urinalysis and urine microscope. Painless – serious! Glomerulonephritis Tumours of the kidney(renal carcinoma), ureter, bladder or prostate Renal Tuberculosis Schistosomiasis(haematobium) Hypertensive nephrosclerosis Interstitial nephritis (unless very acute/severe) Acute tubular necrosis Renal ischaemia (renovascular disease) Distance running or other severe exercise Coagulation disorders, anticoagulant therapy Painful Urinary tract infection: severe cystitis ; urethritis; Renal stones with obstruction; ureteric stone colic Loin pain-haematuria syndrome May be either Urinary tract infection Reflux nephropathy and renal scarring Adult polycystic kidney disease Renal stones without obstruction Pneumaturia ‘fizzy/bubbles’ Passing gas bubbles in the urine is rare. It may be associated with faecuria, in which faeces are voided. It suggests a fistula between the bladder and the colon, from a diverticular abscess, cancer or Crohn's disease. Gynae Chronic renal failure = CKD HPC PAIN Urine Proteinuria Proteinuria is usually asymptomatic and detected by simple urinalysis; it usually indicates kidney disease. Proteinuria up to 2g/24hrs is non-specific. Values greater than this indicate a glomerular abnormality, most commonly glomerulonephritis or diabetic nephropathy. Radioimmunoassay techniques can detect albumin excretion rates as low as 30 mg/day(early diabetic nephropathy). Proteinuria may occur in normal patients with febrile illness. Proteinuria <1 g/l which disappears when lying supine (orthostatic proteinuria) is occasionally found in healthy young subjects in whom protein is not detected in the first urine passed after sleeping recumbent overnight, but is present during the day. Severe proteinuria may produce frothy urine. If it lowers the plasma albumin concentration enough to reduce the plasma oncotic pressure, the patient develops generalized oedema: the nephrotic syndrome. Causes: Renal disease(Glomerulonephritis; Diabetes mellitus; Amyloidosis; Systemic lupus erythematosus; Drugs, e.g. gold, penicillamine; Malignancy, e.g. myeloma; Infection); nonrenal disease(Fever; Severe exertion; Severe hypertension; Burns; Heart failure; Orthostatic proteinuria); Causes of transient proteinuria(Cold exposure; Vigorous exercise; Febrile illness; Orthostatic proteinuria; Abdominal surgery; Congestive heart failure) Menstrual discharge, contraception, pregnancy, births (#+mode of delivery)-esp for incontinent women, previous surgery/radiotherapy(inc risk of PID), smoking(inc risk of bladder cancer), occupation(rubber, dye, chemicals at hairdressers), inherited renal disease(polycystic kidney disease, renal stones) Oliguria, nocturia, polyuria, anorexia/poor appetite, insomnia/sleep disturbance, metallic taste, vomiting, fatigue, hiccups, SOB, pruritus, bruising, oedema, sallow complexion, uraemic fetor, growth retardation in children, restless legs particularly at night, muscle twitching due to hypocalcaemia and, in advanced renal failure, vomiting, diarrhoea, confusion and altered consciousness. Rationale SOCRATES Frequency of micturition must be distinguished from POLYURIA. Causes: Chronic renal failure; Hyperglycaemia as in DM; Diabetes insipidus; Compulsive water drinking; Excessive caffeine ingestion Oligouria: a reduction in urinary output is characteristic of acute renal failure. Anuria: complete cessation of micturition usually suggests obstruction of both kidneys or the bladder outflow Volume, frequency, odour Appearance Due to hydration status, medications, bilirubin levels, foods Orange-brown Conjugated bilirubin Rhubarb, senna Concentrated normal urine, e.g. very low fluid intake Red-brown Blood, myoglobin(rhabdomyolysis), free haemoglobin(haemolysis), porphyrins Beetroot(beeturia), blackberries Drugs: rifampicin, metronidazole, warfarin Brown-black Conjugated bilirubin Drugs: L-dopa Homogentisic acid (in alkaptonuria or ochronosis) Blue-green Drugs/dyes, e.g. propofol, fluorescein Yellow and stingy Asparagus Past Medical History Any similar problems in the past? Recurrent UTIs as a child / adult? Strepto. throat infection/ tonsillitis? Vascular disease? Systemic illness? (SLE, RA, cancer) Prolonged labour/ Caesarian section Pelvic inflammatory disease (PID) JADE TAB MARCH Thyroid Rationale Renal calculi(stones); onset & duration Recurrent infections (particularly urinary - associated with renal scarring URTIs associated with glomerulonephritis and/or vasculitis) Vascular disease at other sites (which makes renovascular disease more likely); anaemia Sexual history (as necessary), menarche, menstruation Diabetes mellitus (associated with diabetic nephropathy and renovascular disease) Hypertension(may cause/result from renal disease) Drug History ALLERGIES (response) Nephrotoxic drugs (anti-hypertensives/ antibiotics include(affect renal function): Aminogycosides(amphotericin, lithium, tacrolimus) Cyclosporins NSAIDs(paracetamol overdose) Frusemide Ace inhibitors Penicillamine Gold Accumulate in renal failure Rationale Iodine Current medication N.B. certain medication/food can affect the colour of urine e.g. rifamipicin, beetroot. ACE-I, angiotensin receptor antagonists and NSAIDS do not affect normal kidneys, but reduce glomerular filtration when the kidneys are underperfused. Digoxin, lithium, aminoglycosides, opioids and water-soluble β-blockers, e.g. atenolol. Insulin Ensure compliance if diabetic? Hyperglycaemia ass with CKD OTC medications OTC NSAIDs can dramatically reduce renal function in systemic infection or hypovolaemia. Homeopathic remedies Indirectly cause renal failure: eg rhabdomyolysis and myoglobinuria cause acute renal failure in intravenous drug users. Renal failure affects drug metabolism and pharmacokinetics, and drugs may affect renal function or damage the kidneys. ‘SADOO’ Social History Rationale Occupation (exposure Living and working in hot conditions with more concentrated urine may increase renal toxins, lead, stones. Exposure to organic solvents may cause glomerulonephritis. Aniline dye and rubber hydrocarbons) workers have an increased incidence of urothelial cancer. Long-term exposure to lead and cadmium may cause chronic renal damage. Alcohol (units) Excess alcohol consumption is associated with hypertensive renal damage and increased incidence of IgA nephropathy. Smoker (pack years) Atheromatous renal vascular disease; nephropathy in diabetic patients; urothelial cancers. Recreational drugs Diet & exercise Take a dietary history in patients with renal stones: intake of water, calcium, e.g. milk and dairy products, and oxalate(plant based food), e.g. chocolate(cocoa), rhubarb, spinach and soya. Assess dietary protein intake in patients with chronic renal failure. Ask about sodium intake in patients with hypertension and renal disease. Sexual practices, overseas travel, housing, spouse/dependents Kidney stones: predisposing factors Environmental and dietary Low urine volumes: high ambient temperature, low fluid intake Diet: high protein intake, high sodium, low calcium High sodium excretion High oxalate excretion; metal ions (Ca2+) bind and form stones High urate excretion Low citrate excretion Other medical conditions Hypercalcaemia of any cause Ileal disease or resection (leads to increased oxalate absorption and urinary excretion) Renal tubular acidosis type I (distal), e.g. in Sjögren's syndrome Congenital and inherited conditions Familial hypercalciuria Medullary sponge kidney Cystinuria Renal tubular acidosis type I (distal) Primary hyperoxaluria Family History Autosomal dominant Polycystic Kidney Disease (APKD) Alport’s syndrome (x-linked) Renal Disease Hypertension Diabetes Parents/siblings alive & well? Rationale Associated with subarachnoid haemorrhage from intracranial berry aneurysms Associated with high-tone sensineural deafness Familial predisposing factors e.g. hypertension, polycystic kidney disease. Some pts with T1DM have inc risk to diabetic nephropathy Example case History & Examination of a patient with Urological Disease Case Presenting complaint Students: PAINFUL HAEMATURIA (right ureteric calculus) Paul Hamilton, a 37-year-old man, presents as an emergency to the A&E dept at SJUH with a history of right-sided abdominal pain and the passage of bloodstained urine. How do you approach this? You should concentrate on the history of the presenting complaint: nature of pain, haematuria. Associated features. The characteristics are: - the pain is colicky, starting in the right renal angle and radiating round into the groin - it is severe, and the patient finds it impossible to find a comfortable position - it comes in waves and is associated with nausea - the urine is tinged pink in colour - there is no pain on passing urine itself - the patient has no history of previous urinary tract symptoms and has been fit and well in the past PMH - nil of note family history - nil of note drug history - nil of note allergies - ?penicillin rash in the past review of systems - CVS: no specific features RS: no specific features GIT: no specific features GU: no specific features CNS: no specific features Locomotor: no specific features social history - foundry worker - alcohol: 20-30 units per week - smoking: none Comment: This is a fairly classic history of right-sided renal colic. You should appreciate the type of pain seen with renal colic, and the fact that as the kidneys are paired organs the colic is felt not in the mid line as with intestinal colic but on either the right or left side of the abdomen. Features on examination - the patient would be in pain and obviously distressed - the abdomen would be tense but there would be no other specific signs. Specific examination features for students to practise: general abdominal examination palpation of kidneys palpation of bladder urinalysis inspection of urological X-rays (KUB, IVU) MSU results Below is a list of the common symptoms of urological disorders. Tick when you are confident you can recognise a pt’s description of them. In addition, give one example of a condition which may present with this symptom. Incontinence Urinary frequency Polyuria Haematuria Dysuria Acute retention Loin pain Testicular pain/swelling Give 3 examples of drugs used in treatment of the following: glomerulonephritis urinary incontinence List 4 risk factors for urological disorders (if necessary indicating for which condition risk applies): 1 2 3 4 WEEK 17: Urological system - Examination Physical examination may be normal even with significant kidney disease.

Enlarges downwards (spleen enlarges to RIF) Edge usually rounded ( not as sharp as liver or spleen ). Moves late on inspiration. Palpable bi – manually (the right hand is placed anteriorly in the lumbar region and the left hand is placed posteriorly in the loin; palpate when pt is breathing in; easier to feel the right kidney as it liees lower than the left).State size, surface, consistency Bladder Loin tenderness MAY BE ABLE TO GET ABOVE IT Resonant to percussion ( the ascending and descending colon is fixed and often it is gas filled. It is anterior to the kidney and thus a renal mass may give a resonant note on percussion because of this). Both kidneys may be enlarged: Polycystic kidney disease(nodular and irregular); amyloidosis; acute glomerulonephritis; tumour or infiltration(firm and irregular); One kidney may be enlarged because of compensatory hypertrophy due to renal agenesis, hypoplasia or atrophy, or surgical removal of the other kidney. It may also be due to renal tumour or hydronephrosis. Normal bladder is not palpable A distended bladder as in urinary retention : a smooth, often tender swelling ( oval shaped ) palpable suprapubically -> dome may reach the umbilicus lateral and upper border -> easily defined cannot get below it(can’t define lower border) -> ‘arises from the pelvis’ symmetrical and central dull to percussion swelling disappears on catheterisation Causes of enlargment: pregnant uterus, fibroid uterus, ovarian cyst. Ask pt to sit up; strike renal angle with ulnar aspect of fist to test for tenderness after warning them. Most commonly due to acute pyelonephritis or acute urinary obstruction Lymph nodes Percussion Bladder Loin percussion tenderness Shifting dullness Auscultation Renal arteries Performed/Identified Percuss over a resonant area in upper abdomen in the midline and then down towards the pubic symphysis. A change to a dull percussion indicates the upper border of the bladder Test for ascites(nephritic syndrome or pts with peritoneal dialysis) Performed/Identified Auscultate over posterior loins and in the epigastrum using the diaphragm of the stethoscope for bruits (increases risk of co-existent atheromatous renal artery disease) Genitailia Inspection Performed/Identified Skin changes e.g. Redness, ulceration Swelling, pitting oedema Stress incontinence (cough) In males – ask adults to retract their foreskin.
