[Colorenal fistula complicating renal tuberculosis: a case report]

Urogenital tuberculosis is little suspected and known by clinicians. Colorenal fistulas, although rare, are complex forms of renal tuberculosis occurring in patients with advanced-stage disease. They generally occur in the ascending and descending colon. We here report the clinical case of a 58-year-old female patient presenting to the Emergency Department with severe acute left pyelonephritis. Abdominal CT scan objectified left pyonephrosis with left colorenal fistula. The patient had poor clinical, biological outcome despite resuscitation measures and antibiotic treatments. Urgent left nephrectomy was performed with disconnection and drainage of colorenal fistula. Histology showed renal tuberculosis. The patient received antibacillary drugs according to 2ERHZ/4RH guidelines. The treatment of this type of TB should be adequate to avoid recurrences that could be more complicated to manage.
