Transobturator tape for female stress incontinence: follow-up after 24 months.

OBJECTIVE

The objective of this paper is to evaluate the effectiveness of transobturator vaginal tape (TOT) in the treatment of female stress urinary incontinence (SUI) and to analyze functional results and quality of life after 24 months follow-up.

METHODS

The study included all women with SUI who underwent a TOT procedure in which the sling passes from the obturator foramen from the outside to the inside, under general or regional anesthesia from December 2004 to January 2006. All study patients must have had a minimal follow-up of 24 months. The patients were prospectively evaluated, and the following factors were assessed: number of pads used per day, physical examination including pelvic examination, urinalysis, urogenital distress inventory (UDI-6), analog global satisfaction scale (GSS), pad weight test, and urodynamic studies including filling cystometry and Valsalva leak point pressure (VLPP) test.

RESULTS

Fifty-two consecutive patients who fulfilled the inclusion criteria underwent TOT procedure by 1 surgeon. The mean age was 50 +/-9 (range 37-72) and minimal follow-up was 24 months (range 24-30 months). Two patients were lost to follow-up after 12 months and 3 patients did not come for the 24-month evaluation. The mean operative time was 18 minutes +/-4 (range 15-31), with an average amount of bleeding 57 cc +/-22cc. Our results demonstrate a 92% cure or improvement rate after 12 months, and an 85% after 24 months.

CONCLUSION

The transobturator approach from outside to inside is a very effective treatment of SUI with low morbidity. However, longer follow-up in larger populations should assess the long-term reliability of this procedure.
