ntroduction: Extracorporeal shock wave lithotripsy has been confirmed as the least invasive and the most widely used treatment for kidney and ureteral stones. However, as with any other type of therapy, potential compli-cations do exist. Case presentation: Herein, we describe a 55-year-old male patient who developed symptoms of acute pancreatitis one day after extracorporeal shock wave lithotripsy for left renal stones. The patient used to manage himself with NSAIDs till he presented to the emergency department with severe epigastric pain and tenderness due to giant pancreatic pseudocyst formation. The pseudocyst was treated by endoscopic cystogastrostomy using metallic stent with uneventful recovery. In addition, we extensively reviewed all available literature studies of pancre-atitis and pancreatic pseudocyst occurring after extracorporeal shock wave lithotripsy. We summarized all re-ported cases and presented them in a comprehensive table. Discussion: Post ESWL acute pancreatitis is a rare clinical entity with only 11 reported cases. In all cases, abdominal pain was the most common symptom that occurs in less than 24h following ESWL treatment. So it should be considered in the differential diagnosis of acute abdominal pain after ESWL. Conclusion: Although ESWL is generally considered safe and effective treatment; however, major complications have been reported to occur in less than 1% of patients. One of the extremely rare complications is the devel-opment of pancreatitis and pancreatic pseudocyst.
