Bladder neck obstruction

Description

A condition of the bladder, caused by congenital or acquired abnormalities that impair the muscles that connect the bladder to the urethra. This condition is characterised by obstruction of the bladder neck and constricted opening during urination. This condition may also present with pelvic pain, pollakiuria, incontinence, or incomplete bladder emptying. Confirmation is by video urodynamics to observe the obstruction as the bladder fills and voids.
