The effects of not doing pelvic floor muscle repair include bladder sphincter laxity, pelvic organ prolapse and vaginal laxity. 1. Relaxation of bladder sphincter: after delivery, the pelvic floor muscle is damaged and the tension of the main muscle group for controlling urine decreases. When the patient coughs or walks fast, the abdominal pressure rises, which will cause the urine in the bladder to overflow out of the body, resulting in leakage of urine and urinary incontinence. 2. Prolapse of pelvic organs: after the injury of pelvic floor muscle, its strength and elasticity decreases, the support of the uterus, bladder, urethra, vagina and rectum decreases, which causes prolapse of the anterior and posterior walls of the vagina, uterine prolapse, bulging of the bladder, rectum and small bowel, and so on. 3. Vaginal laxity: The relaxation of the pelvic floor muscles leads to vaginal laxity, patients will experience a feeling of swelling, vaginal discharge, and reduce the quality of sexual life. It is recommended that patients undergo pelvic floor muscle repair about 42 days after delivery.
