ABSTRACT: Objective: To evaluate the outcomes of transobturator mid-urethral sling (TO-MUS)
with or without reconstructive pelvic floor surgery (RPFS) in Chinese women
with stress urinary incontinence (SUI) after 10 years. Methods: This was a prospective observational study on Chinese women undergoing
the insertion of TO-MUS with or
without RPFS. All patients were assessed at 1-year and 10-year by urodynamic
study (UDS). Objective cure was defined as the absence of urine leakage during
provocative maneuvers on filling cystometry. Data regarding subjective outcome
(patient perception), quality of life changes (Urogenital Distress
Inventory-short form (UDI-6), Incontinence Impact Questionnaire-short form (IIQ-7))
and adverse events were also collected. Results: Of 104 eligible patients, 99 patients completed the 10-year evaluation.
57 patients (57.6%) underwent TO-MUS only and 42 patients (42.4%) underwent
TO-MUS with concomitant RPFS. At 10-year follow-up, the overall objective cure
rate was 86.9% and overall subjective cure rate was 80.8%. In TO-MUS only group,
the objective and subjective cure rates at 10-year were 84.2% and 78.9%
respectively. In TO-MUS with RPFS group, the objective and subjective cure
rates at 10-year were 90.5% and 83.3% respectively. Compared TO-MUS only group
with TO-MUS with RPFS group, there were no statistically significant differences in
objective cure rate (84.2% vs. 90.5%, p
= 0.55) and subjective cure rate (78.9% vs. 83.3%, p
= 0.58). Conclusion: TO-MUS is an effective treatment for SUI in Hong Kong Chinese women.
Concomitant RPFS during the procedure of TO-MUS does not affect the success.
