Extracorporeal shock wave lithotripsy (ESWL) has been adopted by multiple medical disciplines as an effective and relatively safe modality for stone fragmentation. Complication rates are typically low but can vary from those with minimal consequence to life-threatening injuries. We report the first case of a perinephric hematoma with resulting acute kidney injury (AKI) following an intended pancreatic stone ESWL. We believe that this complication resulting from inaccurate lithotripter stone

... eting of the pancreas can be prevented in the future with improved preoperative patient assessment and early urologic management in the setting of concurrent renal stones and renal pathology. Purpose: Urologists are not familiar with pancreatic lithotripsy nor are gastroenterologists familiar with the side effects of renal lithotripsy. We present a case highlighting both of these entities. Materials and Methods: A case of pancreatic lithotripsy is presented with the unusual complication of a perinephric hematoma. Results: A potentially serious complication arising from an intended pancreatic lithotripsy occurred as a result of inadvertent targeting of a pancreatic stone. Conclusions: With careful planning and collaboration between specialties, urologic complications of pancreatic lithotripsy can be avoided.
