lower urinary tract symptom (LUTS, prostatism)

Etiology: - causes of outflow obstruction - benign prostatic hyperplasia - urethral stricture - increased urine flow (polyuria) - diuretics - hyperglycemia - hypercalcemia - polydypsia - detrusor overactivity - older age - irritation - urinary tract infection - caffeine, spices, alcohol, carbonation - benign prostatic hypertrophy - bladder stones - urethritis - prostatitis, prostate cancer, bladder cancer - neurogenic bladder - spinal cord injury - Parkinson's disease - obstructive sleep apnea - exacerbation by medications - bronchodilators - antidepressants - diuretics - anticholinergics - antihistamines - nasal decongestants [19] - opioids - surgical procedure that may affect innervation of the bladder or urethral sphincter [19] Epidemiology: - up to 30% of men > 50 years of age - > 50% of men > 60 years of age [19] Physical examination: - prostate exam (digital rectal examination) - assess prostate size, contour, rectal spinchter tone, perineal sensation - lower abdominal exam Clinical manifestations: - irritative symptoms - urinary frequency - urinary urgency - nocturia - urge incontinence - obstructive symptoms - urinary hesitancy, difficulty initiating urination - straining - a weak urinary stream, prolonged urination, dribbling - urinary retention - sensation of incomplete bladder emptying - bladder fullness, palpable bladder [17] - overflow incontinence Laboratory: - urinalysis a) pyuria suggests infection b) hematuria may be sign of: infection, malignancy c) glycosuria suggests poorly-controlled diabetes mellitus d) trumps PVR even in the absence signs/symptoms of UTI [17] - ref [17] cites 'active urine sediment' as indicator of postobstructive uropathy - prostate-specific antigen in serum Special laboratory: - International Prostate Symptom Score or AUA symptom index to assess severity - postvoid residual (PVR) in men (prior to discontinuation of medications) [3] - urodynamics & cystoscopy as indicated Differential diagnosis: - chronic pelvic pain syndrome - benign prostatic hyperplasia Management: - see BPH - no treatment for AUA symptom index interpreted as mild disease (< 8) [17] - lifestyle modification* for AUA symptom index < 8 [3] - control urinary urgency with pelvic floor muscle contraction - avoid rushing to rest room - prompted voiding for patients with dementia - sit to void to empty more completely [19] - sleep hygiene [21] - pharmaceutical management - tamsulosin - do not use in combination with prazosin [19] - residual symptoms of urinary urgency & urinary incontinence due to overactive bladder may respond to antimuscarinic agent or mirabegron - fesoterodine (or other parasympatholytic) may be used with tamsulosin [15] - tolterodine is another parasympatholytic for use with tamsulosin [19] - dutasteride or finasteride with delayed effectiveness for large prostate - withdrawal of tamsulosin from combined tamsulosin/dustateride therapy after 12 months does not exacerbate symptoms [16] - tadalafil also used for BPH - antimuscarinic agent or mirabegron preferable add-on to tamsulosin especially if symptoms of overactive bladder [19] - Botox no better than placebo [5] - referral to urology - suspected prostate cancer - hematuria - recurrent urinary tract infections - urinary retention - urethral stricture (history or risk of) - neurogenic bladder - abnormal serum PSA - refractory LUTS * additional suggested lifestyle modifications include: - reduce fluid intake - correct constipation - increase frequency of voiding to empty bladder [3]
