Study Notes
Treatment and Management of Lower Urinary Tract Symptoms (LUTS) in Males
- Lifestyle and behavioral modifications are recommended as initial steps to manage LUTS, including avoiding fluids before bedtime, reducing caffeine and alcohol intake, and double voiding to empty the bladder more completely.
- Treatment is indicated for symptom relief if lifestyle and behavioral modifications are not sufficient, and in some cases, to reverse complications of LUTS/BPH.
- Symptoms of LUTS include storage (frequency, urgency, and nocturia) and voiding (slow or decreased force urinary stream, straining to void, etc.).
- Shared decision-making with patients is essential to choose the preferred treatment after initial evaluation, considering the risk/benefit profile for all treatment options.
- Patients may benefit from medical or surgical treatment, with a trial of medical management generally recommended before surgical intervention.
- Patients should continue lifestyle modifications during medical treatment and be monitored for treatment success and possible adverse events.
- Men with LUTS/BPH may have multiple medical comorbidities and use medications that can worsen LUTS, necessitating awareness of iatrogenic causes before starting treatment.
- Referral to a urologist is appropriate in certain clinical scenarios, such as complications of renal insufficiency, refractory urinary retention, recurrent urinary tract infections, etc.
- Alpha-adrenergic receptor blockers are used as initial pharmacologic agents in most patients with LUTS/BPH, with treatment effects seen within days.
- Selective alpha-1 adrenergic receptor antagonists are efficacious in relieving symptoms of BPH and have fewer adverse effects than nonselective blockers.
- The most commonly reported adverse effects of alpha-adrenergic receptor blockers include dizziness, rhinitis, and intraoperative floppy iris syndrome (IFIS).
- Hypotension is an important potential side effect, and blood pressures should be monitored in patients started on alpha-adrenergic receptor blockers.
