Midurethral sling outcomes: tension-free vaginal tape versus Pelvilace

We sought to compare the complications and efficacy of tension-free vaginal tape (TVT) and Pelvilace. Chart reviews and telephone questionnaires documented complications, urinary symptoms [Urogenital Distress Inventory short form (UDI-6) and Patient Global Impression of Improvement (PGII)], and re-operations. Failure was defined as PGII >= 4 (no change or worse) or reoperation for urinary incontinence. There were 91 TVT and 22 Pelvilace slings. The TVT group had lower rates of urinary retention beyond 1 week (8% vs. 43%, p < 0.001) and reoperation for retention (1% vs. 19%, p < 0.001). Median changes in UDI-6 scores were -33.3 for the TVT group and -29.6 for the Pelvilace group (p=0.21). Median PGII scores were 1 for the TVT group and 2 for the Pelvilace group (p=0.024). Ten percent of the TVT group and 24% of the Pelvilace group (p=0.095) were failures. Urinary retention was more common after Pelvilace than TVT slings. Symptomatic outcomes and failure rates were similar.
