lower urinary tract symptom (LUTS, prostatism)
Jump to navigation
Jump to search
Etiology
- causes of outflow obstruction
- increased urine flow (polyuria)
- detrusor overactivity (overactive bladder)
- older age
- irritation
- urinary tract infection
- caffeine, spices, alcohol, carbonation
- benign prostatic hypertrophy
- bladder stones
- urethritis
- prostatitis, prostate cancer, bladder cancer
- neurogenic bladder
- obstructive sleep apnea
- exacerbation by medications
- 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)
- lower abdominal exam
Clinical manifestations
- irritative symptoms (overactive bladder)
- obstructive symptoms
- urinary hesitancy, difficulty initiating urination
- straining
- a weak urinary stream, prolonged urination, dribbling
- urinary retention
- overflow incontinence
Laboratory
- urinalysis
- pyuria suggests infection
- hematuria may be sign of: infection, malignancy
- glycosuria suggests poorly-controlled diabetes mellitus
- 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
Diagnostic procedures
- 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
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]
- control urinary urgency with pelvic floor muscle contraction
- lifestyle modification* for AUA symptom index < 8[3]
- pharmaceutical management
- tamsulosin
- 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]
- solifenacin use with tamsulosin reduces prostate volume & vascularity[22]
- fesoterodine (or other parasympatholytic) may be used with tamsulosin[15]
- 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]
