Stress incontinence occurs when a man unintentionally releases a
small amount of urine when he coughs, laughs, strains, lifts, or changes
posture. It is most common after a man has had his prostate gland removed and
there was damage to the nerves or to the external bladder outlet valve
(sphincter). After a man's prostate gland is removed, the bladder neck no
longer has adequate support from the prostate. The sphincter must then do all
the work of maintaining continence, and the extra pressure of sneezing,
coughing, or straining forces urine past the outlet.
Stress incontinence is often treated with
biofeedback but may require surgery if the problem is
severe and persistent.
