Introduction and hypothesis
For decades, the pubovesical (PV) sling has been in the armamentarium of the fistula surgeon for treating persistent urinary incontinence after successful fistula closure. We report our early experience with slings, and then also introduce a new “tight” PV sling technique for management of post-fistula urethral leak. Our hypothesis is that performance of tight slings might result in improved continence for women with persistent urinary incontinence after obstetric fistula closure.
Methods
Data from 120 patients in whom some type of sling procedure had been performed between 1996 and 2012 were extracted and labeled as “early slings.” Beginning in October 2014, more complete data were recorded and a more uniform approach was undertaken in 40 patients. Data were extracted from their charts and recorded as “tight slings.” This information was analyzed using Chi-squared analysis.
Results
Tight slings were more successful in patients who had less severe fibrosis and who had a shorter time since initial injury. Thirty percent of women who underwent tight slings had improved continence at follow-up.
Conclusion
Persistent urinary incontinence despite successful surgical closure of obstetrical fistula remains a difficult problem. Tight slings may be warranted in an attempt to avoid urinary diversion.
