Surgical treatment of female stress urinary incontinence with a transobturator tape (Monarc): Short-term results of a prospective multicenter study

Aim: Transobturator tape (TOT) kits approved as medical instruments are still not available in Japan. This study aimed to: (1) assess the outcomes of TOT using Monarc (American Medical Systems; AMS Inc, Minnetonka, MN, USA) in women with stress urinary incontinence (SUI); (2) evaluate possible different surgical outcomes in women with urethral hypermobility (UH) and/or intrinsic urethral deficiency (ISD); and (3) evaluate the possibility of improvement of preoperative urgency and urge urinary incontinence after TOT in mixed urinary incontinence (MUI). Methods: Data from 140 women with SUI in a prospective multicenter study were examined at 3–6 months follow‐up. Results: 82.1% of the patients were cured and 10.7% showed improvement. The surgical outcome was significantly better in UH than in UH combined with ISD or ISD. In 44 MUI patients, 79.6% were cured and 15.9% showed improvement. Urgency improved in about 75% of patients after TOT. Conclusion: TOT is effective for both SUI and MUI, with urgency improving.
