Renocolic Fistula after Extracorporeal Lithotripsy: Case Report and Literature Review of a Rare Complication of a Common Procedure

Extracorporeal lithotripsy (ESWL) is one of the most common urological procedures. Among its possible complications, renal parenchymal lesions are rare (approximately 7%). This is a case report of a renocolic fistula after ESWL. It is a very rare complication and without descriptions in the literature of association with ESWL. Because it is a rare lesion, there is no standardized treatment or data that makes it possible to determine the best conduct. The present case required a surgical approach to correct the fistula. It was possible to preserve the affected kidney, which is even rarer in the medical literature.
