Original Article



Single-incision devices for the treatment of stress urinary incontinence (SUI) have been introduced in the last few years. We report a comparison between Obturator Tension-free vaginal tape (TVT-O®) and Contasure-Needleless (C-NDL®).


One hundred and fifty-eight women with primary SUI were scheduled to receive TVT-O® or C-NDL® and follow-up during the first year. Epidemiological information, complications, blood loss, and pain level were recorded. We also analyze stress test and quality of life.


Sixty-three (87.5%) C-NDL® presented a negative stress test, compared with 54 (90%) of TVT-O® (p value 0.015 for non-inferiority test). Sandvik Severity Index was 0 in 75.4% in the C-NDL® group and 87.3% in the TVT-O® (p < 0.015). Complication rate and degree of satisfaction were similar in both groups. Statistically, there were differences (p = 0.012) in postoperative pain in the TVT-O® group.


C-NDL® provides similar outcomes as TVT-O® after 1-year follow-up. It is necessary that long-term data confirm our results.
