Rare vascular complication of ESWL pseudoaneurysm of arc of Buhler.

Extracorporeal shock wave lithotripsy (ESWL) is a standard treatment for nephrolithiasis. It is widely employed due to its relative safety profile when compared with other treatment options. Recognised complications include localised pain at site, steinstrasse, perinephric haematoma and ureteric obstruction. This report presents a rare non-documented complication of ESWL, pseudoaneurysm of the arc of Buhler, a branch artery of the superior mesenteric artery.
