Uncommon complication of endoscopic ureterolithotripsy: The stone granuloma

Abstract  Endoscopic management of urolithiasis is one of the commonest urological procedures today. It is usually safe and effective but one of the possible complications is ureteral obstruction. Stone fragmentation after ballistic lithotripsy and ureteral wall perforation could explain the mechanism responsible for this occurrence. We report a case of stone granuloma, occurring after a ballistic ureterolithotripsy.
