Comparison of the Short Term Results of Monarc and TVT-O Transobturator-tape Procedures for the Treatment of Stress Urinary Incontinence.

Puropose: Transobturator sling is a new minimally invasive treatment for female stress urinary incontinence. We compared the efficacy and safety of the two procedures, Monarc and TVT-O. Material and methods: We included 110 patients with stress urinary incontinence who underwent the Monarc (n=52) or TVT-O (n=58) procedure and followed up at least for 1 year. Preoperative evaluations, the indices of voiding and postoperative complication were investigated. They were analyzed by Student's t-test, Paired t-test and chi-square test. Results: There were no significant difference in the preoperative patients' characteristics, postoperative complication and success rate between the two groups. The preoperative and postoperative storage symptoms between two groups had no significant difference but the patients of both groups had significant improvement in storage symptoms such as frequency and urgency after surgery. Conclusions: The Monarc and TVT-O is equally effective and safe procedures as a treatment method of female stress urinary incontinence. (J Korean Continence Soc 2008;12:163-8)
