Enlarged prostate

Synonyms: Benign prostatic hyperplasia (BPH), Benign prostatic hypertrophy

Medical Specialties: Surgery, Urology

Clinical Definition

A common urinary tract disorder for men over age 60, an enlarged prostate gland presses against the urethra (tubal transport) and can block the flow of urine from the bladder. 

In Our Own Words

The prostate is a walnut-shaped gland at the base of the male bladder that produces a fluid that forms part of semen. As men age, their prostates often become enlarged, which can block the flow of urine from the bladder. When this happens, the bladder wall becomes irritated and contracts more often, causing more frequent urination. An enlarged prostate can lead to problems with the bladder, urinary tract or kidneys if left untreated. Treatments include medication, lifestyle changes and surgery.
