Abstract:
This case illustrates a rare complication of an impacted ureteric stone which eroded through the wall of the ureter leading to formation of a psoas abscess. Ureteric stent placement and percutaneous drainage of the abscess were insufficient to resolve the problem. Renal scan revealed poor function and the left kidney was removed. It showed evidence of acute supporative pyelonephritis with nephrolithiasis.
