Colovesical fistula: a rare complication after renal transplantation

Abstract

Colovesical fistula per se is a rare condition and most commonly occurs secondary to diverticular disease in normal patients. Colovesical fistula in the setting of post-renal transplantation is even rarer and very few cases have been reported in literature. Patients with autosomal-dominant polycystic kidney disease (ADPKD) are predisposed to diverticulosis and hence are at a higher risk for fistula formation. Herein, we report a case of colovesical fistula in a renal allograft recipient with ADPKD in the absence of diverticulosis. The patient was successfully operated and is stable with no complications at 1-year follow-up.

Unique case of colovesical fistula in a renal allograft recipient

“…Urine culture was positive for E. coli . One other case reported by Subbiah et al also had no apparent cause and the patient presented 5 years after renal transplantation 4. Time of presentation in the five reported cases ranged from 2 months to 5 years.…”

“…It usually occurs secondary to large bowel diverticular disease, malignancy or inflammatory bowel disease. Colovesical fistula in a renal allograft recipient is very rare and only five cases have been reported in the English literature 1–5. Diagnosis and management in such rare cases are challenging, due to the infrequency of presentation and diagnosis 6.…”
