Scope of this summary

Adults with bothersome lower urinary tract symptoms plausibly attributed to benign prostatic hyperplasia. BPH is a histologic and anatomic process and must not be assumed to explain every storage or voiding symptom. Acute retention, infection, hematuria, prostate cancer, neurogenic bladder and urethral stricture require separate evaluation.

The Bottom Line

  • Use medical history, physical examination, urinalysis and a validated symptom score such as the International Prostate Symptom Score for initial evaluation, while assessing bother and patient goals.
  • Offer behavioral modification, medical therapy or procedural discussion according to symptom burden, prostate features, risk of progression, adverse effects and preference rather than prostate size alone.
  • Use an alpha blocker for bothersome moderate-to-severe LUTS when appropriate; choose from blood pressure, orthostasis, ejaculation effects, cataract surgery and interacting medicines rather than assuming class equivalence.
  • Reserve a 5-alpha-reductase inhibitor, alone or combined, for demonstrable prostatic enlargement and counsel that benefit develops slowly and can affect sexual function and PSA interpretation.
  • Recommend surgery for renal insufficiency secondary to obstruction, refractory retention, recurrent infection or bladder stones, gross hematuria from BPH or symptoms refractory to or unwilling to use other therapy.

Practical clinical workflow

1
Separate weak stream, hesitancy, intermittency and incomplete emptying from urgency, frequency, nocturia and incontinence; review fluids, caffeine, alcohol, diuretics, antihistamines and anticholinergic medicines.
2
Perform abdominal, genital and digital rectal examination when appropriate; obtain urinalysis and discuss PSA testing through the applicable early-detection framework when the result would change management.
3
Use IPSS and shared decisions to start behavior change or medication, documenting blood pressure, sexual priorities, fall risk and prostate-enlargement evidence.
4
Review within four to twelve weeks after treatment starts, repeating the symptom score and considering post-void residual or uroflowmetry when response or emptying is uncertain.
5
Before a procedure, assess prostate size and shape, post-void residual and flow, using pressure-flow testing when diagnostic uncertainty could lead to an ineffective intervention.

Safety boundaries and escalation

  • Painful inability to urinate with a distended bladder requires urgent drainage and assessment, with sepsis, kidney injury and neurologic causes addressed immediately.
  • Gross hematuria, recurrent infection, stones, hydronephrosis or renal impairment should not be attributed to uncomplicated symptoms without urologic evaluation.
  • Alpha blockers can cause hypotension and falls and can affect cataract surgery; coordinate with ophthalmology and review interacting antihypertensives.
  • A change in PSA during 5-alpha-reductase therapy requires correct interpretation and cancer evaluation rather than simple reassurance from a lower measured value.
