Benign prostatic hyperplasia (BPH), also known as benign prostatic hypertrophy, is a histologic diagnosis characterized by proliferation of the cellular elements of the prostate, leading to an enlarged prostate gland. Chronic bladder outlet obstruction (BOO) secondary to BPH may lead to urinary retention, abnormal kidney function, recurrent urinary tract infections, gross hematuria, and bladder calculi.
