Urinary incontinence is uncontrollable leaking of urine from the bladder.
Overflow incontinence is a common kind of urinary incontinence that occurs in older men.
It is usually caused by enlargement of the prostate gland. Urinary incontinence is an embarrassing problem for as many as 1 in 3 Americans age 60 or older. The prostate gland, about the size and shape of a chestnut, wraps around the urethra between the pubic bone and the rectum, below the bladder. As many men get older, the inner part of the gland gradually enlarges and compresses the urethra, making urination more difficult. As obstruction from the enlarging prostate gland increases, the bladder may become overactive, causing frequent urges to urinate.
