Reno-duodenal fistula as a rare complication of percutaneous nephrostomy: A case report

Abstract

Renoduodenal fistula is a rare condition where a pathological tract is formed between the kidney and duodenum. This condition is caused by various etiologies, such as tuberculosis, malignancy, percutaneous nephrostomy procedure, cryoablation procedure in malignancy, and chronic infection. In this case, we report a case renoduodenal fistula caused by large staghorn calculus, precipitated by a previous history of trauma. Renoduodenal fistula is a rare condition that often presents without symptoms. This condition can be caused by chronic infection of the kidney, and one of the etiology is an infected large staghorn calculus.
