bph (benign prostatic hyperplasia) is an enlargement of the prostate gland. this gland surrounds the tube that drains the urine from the bladder. the symptoms of bph can be caused by a tensing of the enlarged muscle in the prostate gland which blocks the passage of urine. this can lead to such symptoms as: a weak or start-and-stop stream when urinating a feeling that the bladder is not completely emptied after urination a delay or difficulty in the beginning of urination a need to urinate often during the day and especially at night a feeling that you must urinate immediately.
