Stone granuloma--not to be forgotten as a delayed complication of ureteroscopy.

Endoscopic management of urolithiasis is one of the commonest urological procedures today. Its safety and efficacy in the management of ureteral calculi have been proven. A stone granuloma is a rare cause of recurrent ureteral obstruction subsequent to ureteroscopic stone removal. After its initial description by Dretler and Young [J Urol 1993;150:1800-1802] there have been sporadic reports of stone granuloma and paraureteral calculi secondary to iatrogenic perforations of the ureter and subsequent ureteric strictures as the cause of recurrent ureteral obstruction. We report two cases of delayed stone granuloma following pneumatic lithotripsy during ureteroscopy.
