title: Renocolic fistula following percutaneous nephrostomy: a case report.
abstract: Renocolic fistula is a rare clinical entity. In the past, its incidence was high due to infection, especially tuberculosis, and renal stone complications; which gradually reduced with advancements in antimicrobial therapy and better stone management. The incidence of renocolic fistulae, specifically iatrogenic one, has re-emerged due to minimally invasive renal surgery and regular percutaneous nephrostomy placement for various reasons. We reported a case of fifty-five-years-old gentleman who presented to emergency room with left lithiasic pyonephrosis for which percutaneous nephrostomy was placed. Follow up antegrade pyelography diagnosed hydronephrotic left kidney with stone in renal pelvis with fistula communicating to descending colon. Contrast enhanced computer tomography revealed left non excreting kidney with retrorenal colon and percutaneous nephrostomy tube passing through the descending colon. The final diagnosis of post percutaneous nephrostomy renocolic fistula with non excreting left kidney was made and treated with ligation of fistulous tract and nephrectomy. Patient had uneventful recovery and histopathology showed chronic pyelonephritis.
