Protusion of the urinary bladder through the vaginal wall which can make it difficult to empty the bladder completely. The residual pool of urine in the bladder can form a breeding ground for bacteria. Common in older women, it is also called a cystic hernia. Overflow incontinence may be caused either by an obstruction of the urethra, an underactive detrusor muscle, or both. Obstruction may occur as a result of a cystocele, impacted feces, a narrowing of the urethra, or a pelvic tumor.
A cystocele (SIS-tuh-seal) is a medical condition that occurs when the wall between a woman's bladder and her vagina weakens and allows the bladder to droop into the vagina. This condition may cause discomfort and problems with emptying the bladder. A cystocele may result from muscle straining during childbirth, heavy lifting or repeated straining during bowel movements.
