CT urography (Fig. 2A-E) revealed a clear renal collecting system and no significant hydronephrosis. In MR urography images (Fig. 2F), there was fluid signal in the perirenal space, particularly inside and below the left kidney.
Reoperation was performed to explore the left kidney and ureter. (A) Almost complete occlusion of ureteral stricture was found in the upper ureter (arrow). (B) Surgical wounds of the left kidney (arrow) healed well. (C) The ureter was anastomosed end to end with the routine double-J stent (arrow).
