pros·ta·tism (prosґtə-tiz″əm) a symptom complex resulting from compression or obstruction of the urethra, usually due to benign prostatic hyperplasia (see under hyperplasia). There are both obstructive and neurological symptoms, including diminution in caliber and force of the urinary stream, hesitancy in initiating urination, inability to end it (with subsequent dribbling), a sensation of incomplete bladder emptying, and occasionally urinary retention.Medical dictionary. 2011.
