Purpose:We evaluate the prognostic factors of recurrence in patients after the surgical repair of vesicovaginal fistula. Materials and methods : From 1985: From to 2002 women with vesicovaginal fistula underwent late (>3 months) surgical repair. A multivariate analysis of the data was performed with the EPI-INFO software. All P-values were two-sided, with odds ratio and 95% confidence intervals. Results: A total number of 73 patients underwent 97 procedures with a mean rate of 1.38 procedures/patient. The overall surgical success rate was 86.7%. Multivariate analysis demonstrated that recurrence was statistically significant for multiple fistulas (single vs two or more), fistula size (>10 mm), fistula type (Type I vs Type II), fistula etiology (obstetrical vs non-obstetrical) and the presence of urinary tract infection before the repair. Recurrence risk was fivefold higher for both the size and the type of the fistula, threefold higher for obstetrical etiology and 4.5-fold higher for multiple fistula. The interposition of flaps was a protective factor for recurrent cases. The surgical approach was not a significant prognostic factor of recurrence. Conclusion: Successful closure of a vesicovaginal fistula requires an accurate and a timely repair using procedures that exploit basic surgical principles. Multiple fistula, size and type of the fistula, and obstetrical etiology were the recurrence risk factors. We recommend in all patients with multiple risk factors for recurrence, the interposition of flaps.

Thirty-one hips in 27 young girls, treated for developmental dysplasia of the hip in the authors' institute since 2003, showed persistent radiographic evidence of residual acetabular dysplasia. These hips were registered as candidates for pelvic osteotomy. A prospective study was conducted and these hips were evaluated by magnetic resonance imaging (MRI); the average age of the patients was 5 years. MRI measurement of acetabular angle and acetabular head index in 2 different landmarks (bone and cartilage) was performed. The results were correlated with plain radiographic film evolution. MRI studies revealed sufficient cartilaginous acetabular coverage in 27 hips, cartilaginous acetabular dysplasia in 2 hips, and short acetabulum in 2 others. The 27 hips with thick cartilage of the acetabular roof were subsequently followed up by plain radiographs. The average follow-up period was 2.1 years. The authors observed a spontaneous progressive ossification of the cartilaginous acetabular roof in all the 27 cases. In 4 cases, the correction of the acetabular angle was complete. They concluded that MRI promotes more accurate selection of patients for pelvic osteotomy and aids in the choice of the most appropriate type of osteotomy. Clinical imaging examples are presented and need to be further evaluated.

This study suggests that in Tunisian subjects the GSTM1 null genotype may be associated with an increased risk of bladder cancer. This association appears to depend upon smoking status.
