title: Oil granuloma of the ureter.
abstract: Several years ago we began to inject mineral oil through a ureteral catheter to facilitate stone extraction. Some success was achieved, particularly with impacted calculi. However, we report 2 cases of mineral oil granuloma of the ureter. We now urge that only water soluble lubricants be used in the ureter to avoid this problem.
