In males, the prostate gland lies outside the opening for the urethra. The middle lobe of the prostate causes an elevation in the mucous membrane behind the internal urethral orifice called the uvula of urinary bladder. The uvula can enlarge when the prostate becomes enlarged.

The bladder is located below the peritoneal cavity near the pelvic floor and behind the pubic symphysis. In males, it lies in front of the rectum, separated by the rectovesical pouch, and is supported by fibres of the levator ani and of the prostate gland. In females, it lies in front of the uterus, separated by the vesicouterine pouch, and is supported by the elevator ani and the upper part of the vagina.
