AimsEvaluate the effectiveness and safety of polyvinylidene fluoride (PVDF) transobturator suburethral slings/tapes (TOTs) in the treatment of stress urinary incontinence, and compare them to polypropylene (PP) slings.
Material and MethodsA retrospective cohort study was performed on women treated with a TOT procedure at Vall d'Hebron Hospital between February 2010 and May 2013. A PVDF sling was used in surgeries on 23 women. A comparison group was randomly selected among all women treated with a PP sling in a 1:4 ratio (n = 92). Failure incidence was analyzed by Kaplan-Meier survival functions and a multivariate Cox regression model.
ResultsBoth groups were similar in their initial characteristics. The median follow-up was 24.6 months in the PP group and 21.3 months in the PVDF group. The survival functions showed a higher incidence of failures in the PP group, primarily because of obstructive symptoms. However, the differences were not statistically significant (hazard ratio of failure of PP vs PVDF 4.31; 95% confidence interval 0.56-33.05). Complication rates did not differ between the two groups. More cases of voiding dysfunction were observed in the PP group.
ConclusionsPolyvinylidene fluoride suburethral tapes have been found to have an effectiveness and safety comparable to PP tapes.
