After the urine travels down the ureters, it enters the bladder, a stretchy pouch located just above your pelvis. The bladder's main job is to hold urine. As it gets full, you begin to feel the need to urinate. When you urinate, the smooth muscle of the bladder walls contract, releasing the urine.
In women, the bladder sits on top of the front wall of the vagina. As women age, the bladder can fall or slip out of place because the vaginal wall may sag with time. Childbirth also loosens the vaginal wall. In some women, the bladder may prolapse, meaning it is no longer supported and falls into the vagina. A prolapsed bladder is also known as cystocele or a fallen bladder. As expected, this condition does not affect men, because this is a problem unique to female anatomy.
