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.
Many women with uterine prolapse have no symptoms. If a woman has had a hysterectomy, the top part of the vagina (vault) can become detached from the ligaments and muscles of the pelvic floor. Often, uterine or vault prolapse is associated with loss of anterior or posterior vaginal wall support.
