Transobturator Tape Compared With Tension-Free Vaginal Tape for Stress Incontinence
Bibliographic record
Abstract
OBJECTIVE: To compare the effectiveness of transobturator tape with tension-free vaginal tape (TVT) in terms of objective cure of stress urinary incontinence (SUI) at 12 months postoperatively. METHOD: Women with SUI were randomly allocated to either transobturator tape or TVT procedures and reviewed at 12 months after surgery. The primary outcome was objective evidence of "cure," evaluated by standardized pad test (cure defined as less than 1 g urine leaked). Other outcomes included complications, subjective cure, incontinence-related quality of life, return to usual sexual activity, and satisfaction with surgery. Primary analysis compared the proportion of patients in each group who were cured at 12-month follow-up. RESULTS: A total of 199 women participated (94 in the transobturator tape group, 105 in the TVT group). Sixty-eight women (81%) in the transobturator tape group were cured, compared with 67 (77%) in the TVT group (relative risk 1.05, 95% confidence interval 0.90-1.23, P=.577). On vaginal examination, the tape was palpable for 68 women (80%) in the transobturator tape group and for 24 (27%) in the TVT group (relative risk 0.22, 95% confidence interval 0.13-0.37, P<.001). More women in the transobturator tape group experienced groin pain during vaginal palpation (13 [15%] in the transobturator tape group and five [6%] in the TVT group, P=.044). Quality of life improved significantly from baseline in both groups (30-point improvement in IIQ-7 score for both groups). CONCLUSION: At 12 months, the majority of women had minimal leakage and their quality of life had improved significantly, but differences were not observed between groups. The presence of palpable tape, particularly among the transobturator tape group, is concerning; longer follow-up is needed to determine whether this outcome leads to extrusion or resolves over time.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
