Benign prostatic hyperplasia

Preview

The complaints among middle-aged and older men are familiar—decreased force of urinary stream, hesitancy, dribbling, sensation of incomplete emptying, and nocturia. These are the obstructive symptoms of benign prostatic hyperplasia (BPH), a process that is poorly understood but apparently virtually inescapable. The authors summarize the theories about its etiology, explain the anatomy of the prostate and how BPH causes its common symptoms, describe the workup, and provide illustrations of preoperative hyperplasia and endoscopic resection.
