Clinical Definition

Benign prostatic hyperplasia or BPH is a condition marked by a non-cancerous proliferation of cells, both smooth muscle and epithelial, in the prostate gland's transition zone. Lower urinary tract symptoms accompany the hyperplasia. Diagnosis is made by medical history, physical exam, and tests, including urinalysis. Treatments include watchful waiting, medication and surgery.

In Our Own Words

Benign prostatic hyperplasia, or BPH, is a non-cancerous enlargement of the prostate gland, the walnut-sized gland below the bladder that carries urine from the bladder out through the penis. The prostate produces fluid for the semen.


As the prostate enlarges, urinary symptoms occur, including the need to empty the bladder often, difficulty in beginning to urinate and a feeling that the bladder is not empty even after urinating. Medical history, physical exam and urinalysis contribute to the diagnosis of BPH. Treatment can range from watchful waiting and lifestyle changes to medicines and surgical interventions. If the condition progresses, a man may become unable to empty the bladder and kidney damage or bladder stones can occur.
