Incontinencia urinaria de esfuerzo en la mujer. Comparación de la técnica de Raz y de la técnica de Bologna

Abstract

The aim of this study was to evaluate and compare perioperative morbidity and the long-term results of Raz colposuspension and the Bologna procedure in the treatment of urinary stress incontinence in women. Data from 199 women who underwent either the Bologna procedure (group 1; n = 99) or Raz colposuspension (group 2; n =100) for urinary stress incontinence were retrospectively analyzed. Preoperative clinical data, urodynamic parameters and postoperative complications were compared between the two groups. Logarithmic analysis was used to compare time to recurrence of stress incontinence between the two groups. Multivariate analysis using a Cox proportional hazards regression model was performed to identify possible outcome predictors. The success rate was significantly higher in group 1 than in group 2 (p = 0.00001). The median incontinence- free interval was 51 months in group 1 and was 21 months in group 2 (p = 0.00001). No differences ere found between the two groups in the frequency of intraoperative complications (inadvertent cystotomy, hemorrhage) and postoperative complications (hemorrhagic, infectious and embolic complications). Multivariate analysis using the Cox regression model showed that the only variable correlated with the surgical cure rate was the type of surgical anti-incontinence procedure adopted: Bologna or Raz (p = 0.00001). The results of this study indicate that the Bologna procedure should be preferred over Raz colposuspension in the treatment of urinary stress incontinence when sufficient anterior vaginal tissue is available to create vaginal bands. When this is not the case, Raz colposuspension, as performed in the present study, should be abandoned in favor of other colposuspension methods.
