Cystocell and rectocellular repair or APR is a surgical procedure performed to eliminate vaginal flaccidity and bladder and anal sphincter disorders. Uterine and bladder surgery occurs when the watch muscles of the pelvic organs are weakened by various factors such as old age, puberty or surgery and can no longer hold the uterus and bladder in place and the uterus or bladder is out of its normal position. It descends or prolapses in the pelvis and presses against the vaginal wall, causing it to sag.
