Benign prostatic hyperplasia and male lower urinary tract symptoms

摘要

Symptomatic benign prostatic hyperplasia (BPH) may affect up to 30 percent of men in their early 70s, causing urinary symptoms of bladder outlet obstruction. Symptoms can improve without treatment, but the usual course is a slow progression of symptoms, with acute urinary retention occurring in 1 to 2 percent of men with BPH per year.
