Clinical manifestations of benign prostatic hyperplasia and indications for therapeutic intervention.

The symptomatology of benign prostatic hyperplasia is a complex issue, and the clear-cut indications for therapeutic intervention are few. Overflow incontinence is a clear indication for treatment, and it seems prudent to recommend surgical intervention for patients with large postvoiding residual volumes. Acute urinary retention, recurrent infection, azotemia, and severe hematuria are other strong indications. When the indications are less clear, the patient's perspective on the impact of prostate disease on his life is important.
