Objective To compare the clinical outcome of tension-free vaginal tape (TVT) and TVT-obturator (TVT-O) for female stress urinary incontinence (SUI). Methods Sixty-one female SUI patients were included in our study, in which 33 received TVT procedure and 28 received TVT-O procedure. The patients were followed up for 1 to 62 months post-operatively, averaging at 22 months. Cure was defined as no leakage during the stress test and no residual urine showed by B ultrasound, improvement as less leakage during the stress test after operation, and inefficacy as leakage during the stress test and no difference was detected after operation. Results Age and disease course were not significantly different between the two groups (P>0.05). All patients underwent TVT or TVT-O procedure successfully. Time of TVT ranged from 26 to 45 min averaging at (35.5±4.3) minutes, and it was significantly different from the time of TVT-O which ranged from 15 to 20 min averaging at (7.2±3.1) minutes (P<0.05). Bleeding during the surgery was not significantly different between the two groups (P>0.05). The rate of complications occurring during TVT-O procedure was significantly less and milder than that during the TVT procedure (P<0.05). The cure rate and improvement rate indicated no significant differences between the two groups (P>0.05). Conclusion The evidence available indicates that TVT and TVT-O procedure are both effective and safe for female SUI. Compared with TVT, TVT-O procedure has the advantages of being more convenient, shorter operation time, being less invasive, and fewer complications, and it may be more suitable for female SUI.
