Overflow incontinence is the involuntary release of urineâ€”due to a weak bladder muscle or to blockageâ€”when the bladder becomes overly full, even though the person feels no urge to urinate.
What are the symptoms?
Symptoms of overflow incontinence include:
The sudden release of urine.
A feeling of fullness in the bladder even after urination.
Leakage of urine while sleeping.
A urine stream that stops and restarts during urination.
Difficulty urinating even while feeling the urge to urinate.

Overflow incontinence in both men and women can be caused by:
Conditions that affect the nerves (such as diabetes or multiple sclerosis) and alter a person's ability to sense bladder fullness or that reduce the ability of the bladder to contract.
A blockage in the urinary tract, such as a bladder stone or a urinary tract tumor that constricts the urethra. When blockage occurs in men, it is usually caused by an enlarged prostate gland (benign prostatic hyperplasia, or BPH), cancer of the prostate, or a narrowing of the urethra.
Weakness in the muscle that expels urine from the bladder (detrusor) so that it can't empty the bladder normally.
How is it treated?
Women can be treated for overflow incontinence with:
A catheter. A catheter is a thin, flexible tube that allows urine to drain out. It is inserted into the bladder through the urethra. Different types of catheters include:
