ABSTRACT
One hundred and twenty nine patients with pelvic organ prolapse (stage Ⅲ to Ⅳ according to POP-Q staging) diagnosed in our hospital from January 2010 to December 2016 were enrolled,among whom 66 cases underwent vaginal hysterectomy plus vaginal anterior and posterior wall repair (TO group),63 cases underwent vaginal hysterectomy plus pelvic floor reconstruction with autologous tissue (AT group).Clinical parameters,perioperative and postoperative complications were analyzed.There was no statistically significant difference in intraoperative blood loss,indwelling urethral catheter time,length of hospital stay,and anal exhaust time between group AT and group TO (P＞O.05).The average operation time of group AT was significantly longer than that of group TO (P＜0.05).The postoperative rotation angle of urethra (UR),posterior vesicourethral angle (RVA),and bladder neck descent (BND) of group AT were significantly reduced (P＜0.05).The BND of group AT was significantly smaller than that of group TO 3 months and 12 months after the surgery (P＜0.05).There was no statistically significant difference in UR before and 12 months after surgery in group TO (P＞0.05),while the BND at 12 months after operation in group TO was increased compared to 3 months after operation (P＜0.05).There were significant differences in scores of PFIQ-7 and PISQ-12 before surgery and 12 month after surgery in both groups (P＜0.05).There was no statistically significant difference between the two groups in the incidence of postoperative recurrence and pressure incontinence (P＜0.05).It is suggested that the stability of pelvic floor anatomical structure after pelvic floor reconstruction with autologous tissue is better than that of the traditional surgery,especially for patients with severe pelvic organ prolapse.
