The most common UTIs occur mainly in women and affect the bladder and urethra. 1  Infection of the bladder (cystitis). This type of UTI is usually caused by Escherichia coli (E. coli), a type of bacteria commonly found in the gastrointestinal (GI) tract. 2  Infection of the urethra (urethritis).
Vaginal vault prolapse: This type of prolapse may occur following a hysterectomy (surgical removal of the uterus). Because the ligaments surrounding the uterus provides support for the top of the vagina, this condition is common after a hysterectomy. In vaginal vault prolapse, the top of the vagina gradually falls toward the vaginal opening. This may cause the walls of the vagina to weaken as well.
When the uterine ligaments are severed and the uterus is removed, prolapse of the bowel and rectum is inevitable. Some diminished support to the bladder is also typical. Prolapse of the vagina is also possible after hysterectomy. Vaginal prolapse is rare for women who have not been hysterectomized.
