The sequelae of vaginal wall expansion repair may include damage to surrounding tissues and organs, recurrence of disease and contracture of surgical scar. 1. Damage to surrounding tissues and organs: the anterior and posterior walls of the vagina are adjacent to the rectum and the urethra, etc. If the operation is not performed properly, it may cause damage to the urethra or the intestines, resulting in symptoms such as leakage of urine or feces. 2. Disease recurrence: If the treatment effect of the repair surgery is not satisfactory, it may cause the vaginal wall to bulge again after the surgery. 3. Surgical scar contracture: if the patient belongs to keloid body, it may cause excessive proliferation and contracture of the surgical scar, which may lead to the vaginal opening being too narrow, affecting the quality of sexual life. In order to avoid the above sequelae as much as possible, it is recommended that patients should go to regular hospitals to receive treatment.
