Tension-free vaginal tape: analysis of risk factors for failures.
To investigate whether there are any demographic, clinical, or urodynamic variables associated with an increased risk of failure in women undergoing surgery with tension-free vaginal tape (TVT). We retrospectively analysed 325 consecutive patients who had been operated with the TVT procedure. Patients were assessed with a complete history, physical examination, and urodynamic testing. The operation was done under local or epidural anesthesia and any further surgical procedure was added as indicated. The postoperative evaluation included collection of data on intra- and postoperative complications and analysis of outcomes. The outcome of surgical treatment was evaluated subjectively and objectively. The Statistical Package for Social Sciences (SPSS, Chicago, Illinois, USA) was used for data analysis; P<0.05 was considered significant. The overall complication rate was 14%, voiding dysfunction being the most common. Three hundred and one women were available for the analysis of surgical outcome and the mean follow-up was 34+12 months (median 32 months). Subjectively, 269 women (89%) were cured by the procedure and 13 (4.3%) reported marked improvement. An objective cure was achieved in 263 (87%); 38 patients still having leakage while coughing during postoperative cystometry. Among the numerous presumed risk factors for failed antiincontinence surgery only urethral hypomobility and recurrent stress urinary incontinence were significantly associated with failure of the TVT procedure in our study. However, even in these complicated situations, the cure rate was more than 70%.
