To evaluate and compare the surgical outcome between the innovative tension-free vaginal tape (TVT) and conventional pubovaginal sling (PVS) procedures using polypropylene mesh.


Eighty consecutive women with urodynamic stress urinary incontinence (SUI), who chose to undergo either a TVT (n=23) or a PVS (n=57) procedure using polypropylene mesh based on financial consideration, were recruited for this study. The surgical results were analyzed and compared subjectively and objectively.


The mean follow-up interval was 23 months for the TVT and 20 months for the PVS procedure (P=0.062). Postoperatively, SUI (91.3% vs. 93.0%), concomitant urge symptoms (85.0% vs. 85.3%) and the negative impact of incontinence and urogenital distress on patients' quality of life (79.8% vs. 77.8%) (77.4% vs. 68.8%) had improved markedly. After a multivariable logistic regression analysis, the treatment outcome of SUI was found to be independent of the main effects of patient age, parity, concurrent gynecological surgeries, intrinsic sphincter deficiency, previous failed incontinence surgeries, and concomitant urge symptoms. However, it was significantly related to treatment procedures (TVT vs. PVS) and their interaction with patient body mass index (BMI). Based on the fitted logistic model, we see that TVT performs better than PVS when BMI is less than 27.27 kg/m2, and the advantage of TVT decreases as BMI increases.


Both TVT and PVS procedures using polypropylene mesh are effective treatment modalities for female SUI. However, TVT was not as effective in treating overweight or obese women as PVS.
