Obstetric vesico-vaginal fistula repair: should we trim the fistula edges? A randomized prospective study.

Objective: To test the hypothesis that not trimming the edges of the vesico-vaginal fistula (VVF) during its surgical repair has an advantage in the outcome as compared to the classical teaching of trimming the fistula.

Methodology: Sixty-four females with obstetric VVF were randomized into two groups. Both groups were treated with vaginal anatomical closure in three layers with Martius flap inter-positioning.

Urinary bladder hyperreflexia: a rat animal model.

In this work, we are presenting a rat animal model for bladder hyperreflexia after suprasacral spinal cord transection. Our aim was to standardize an animal model that can be useful in studying this condition. After standardizing the animal model in a pilot study, 26 female Sprague-Dawley rats were subjected to spinal cord transection at the level of T10 vertebra.
