Intravenous urography findings in women with ureteric fistula

INTRODUCTION: Ureteric fistula is one of the major morbidities that can arise from pelvic surgeries. It mainly results from gynaecological and obstetric procedures. Intravenous urography is an imaging modality for the upper urinary tract. Its features may be suggestive of ureteric fistula and it is of great value when medicolegal issues arise. It is however expensive and requires expertise. There are other useful and cheap methods for evaluating ureteric fistula including the use of dye test. There is need to determine if IVU (Intravenous urography) should be recommended for women with this disease. The aim of this study was to determine the features of intravenous urography among women with ureteric fistula and therefore determine its relevance in the management of such patients. METHODS: This was a retrospective study conducted at the National Obstetric Fistula Centre, Abakaliki between January 2012 and March 2017. All patients with ureteric fistula during the study period who were assessed with intravenous urography before surgery were included in this study. RESULTS: The mean age was 38 ± 16 years. Twelve (92.3%) were Christians. IVU showed hydroureters in 46.15% hydronephrosis in 53.85%, non-functioning kidney in 46.15% and ureteric stricture in 7.69%. IVU gave an insight into the side with ureteric fistula except in one who had normal result. CONCLUSION: Hydronephrosis, hydroureters and silent (non-functioning) kidneys are features of IVU in women with ureteric fistulas, however these features are not pathognomonic for the disease.
