To observe the effects of modified pelvic floor reconstruction combined with tension-free vaginal tape-obturator (TVT-O) or tension-free vaginal tape (TVT) on pelvic floor muscle strength, bladder anatomy and quality of sexual life of patients with uterine prolapse and stress urinary incontinence (SUI).

A prospective study was conducted among 80 patients with uterine prolapse and SUI who were admitted to the International Peace Maternal and Child Health Hospital, China Welfare Association from January 2020 to June 2022. They were randomly assigned to the observation group (n=40) and the control group (n=40). The control group was treated with modified pelvic floor reconstruction combined with TVT, while the observation group was treated with modified pelvic floor reconstruction combined with TVT-O. Operation indexes, pelvic floor muscle strength (Oxford) scores, pelvic floor distress inventory-short form 20 (PFDI-20) scores, pelvic organ prolapse quantitation (POP)-Q scores and female sexual function index (FSFI) before operation and six months after operation were compared between the groups. The incidence rates of complications in the two groups in 6 months after operation were calculated.

Operation time and intraoperative blood loss in the observation group were shorter or less than those in the control group [(127.58±10.69) min vs (139.45±13.74) min, (50.06± 8.34) ml vs (61.28±10.06) ml], with statistically significant differences (P<0.05). Six months after the operation, the Oxford scores, PFDI scores, and FSFI scores of the two groups increased. The observation group had higher scores than the control group (P<0.05). Aa, Ba, Ap, Bp, C, and D in the two groups decreased. These indicators in the observation group were lower than those in the control group (P<0.05). The total incidence of complications in the observation group 6 months after operation was 5.00%, lower than 20.00% in the control group (P<0.05).

Modified pelvic floor reconstruction combined with TVT-O can reduce the operation time and intraoperative blood loss, and improve the pelvic floor muscle strength, bladder anatomical structure and quality of sexual life of patients with UP and SUI, with a low incidence of postoperative complications.
