Obstetric Vesicovaginal Fistula Research Articles

Radiology of obstetric vesicovaginal fistula.

The excretory urograms of 70 Nigerian women presenting to the University of Benin Teaching Hospital with obstetric vesicovaginal fistula over a 7-year period are analyzed. The common abnormalities are medial deviation of distal ends of ureters (34%); discrete but smooth pseudoprostatic bladder base indentation (33%); and calyceal clubbing of varying degrees (19%). Other abnormalities observed include hydroureters (18%); bladder calculi (7%); bladder wall calcification (3%), and unilateral nonfunctioning kidneys (3%).

Urinary tract changes in obstetric vesico-vaginal fistulae: A report of 216 cases studied by intravenous urography

Intravenous urographies carried out routinely on 216 cases of vesico-vaginal fistulae were reviewed. All the patients had suffered from urinary incontinence following obstructed labour for periods varying from immediate post-partum period to as long as 35 years with the majority (48%) presenting in the first year of the disease. One hundred and eleven patients (51-4%) showed no urinary tract abnormality. Calyceal abnormality was graded from 1-5 in ascending order of severity. The most frequent abnormality was Grade 1 (or minimal calyceal blunting) found in 75 (71%) of 105 cases showing lesions. Ten patients had non-functioning kidneys. There was no correlation of severity of calyceal grading with duration of the disease. Other notable changes were hydroureter in 75 (34%), medial deviation of the terminal ureters in 21 (9-7%) and bladder calculi in four. The study reveals a high risk of morbidity to the kidneys in patients with vesico-vaginal fistulae and the predominant role of fibrous itssue in tis genesis is postulated.

Pubic changes associated with obstetric vesico vaginal fistulae

The radiological features of the pubic changes in 312 Nigerian women with vesico-vaginal fistulae following obstructed labour are reviewed. Some of the changes represent more severe manifestations of processes that may follow normal delivery. In 23 patients obliteration of the symphysis developed. These followed severe bladder neck fistulae. Factors in the pathogenesis are discussed.

A Study on Different Surgical Methods used for Repair of Vesicovaginal Fistulas in Dhaka Medical College Hospital

This cross sectional study was carried out on hundred patients of vesicovaginal fistula who were admitted and underwent surgical treatment in Dhaka Medical college Hospital (DMCH), Dhaka, during the period of January, 2001 to June, 2003. The aim of this study was to obtain the outcome of the different methods of repair of different types of vesicovaginal fistula. An in-depth interview was taken from patients by using an open ended questionnaire. Necessary information about the procedure applied, together with results of operation were recorded in the data sheet. The result of this study showed that the anatomical success in closure of fistula occurred in 94% cases. In 38% of cases the size of the fistula were small in size, in 49% cases location were at the Junction of bladder neck, 78% of cases experienced no postoperative complications. Route of operation were vaginal in 84% cases. Previous attempt of repair were in 62% cases whereas in 38% women had history of operation. Obstetric vesicovaginal fistula is a curable condition. The success rate has been increased over time. More complicated cases which have been failed in previous attempts of repair are being referred. Most of the unsuccessful repair were bad cases (2%). So more training and experience of surgeons for repair of fistulas, employing modified technique wherever applicable can improve the result.
