[One-stage operation of ureteropelvic junction and ureterovesical junction stricture]

One-stage surgical management for ureteropelvic (UP) and ureterovesical (UV) strictures is reported. A 3-year-old boy with UP and UV strictures on left side, underwent nephrostomy at 4 months old. The plastic operations which were Anderson-Hynes method for UP stricture and submucosal tunnel method with tailoring of dilated ureter for UV stricture were performed at the same time. The post-operative intravesical pyelogram and renal scintigraphy showed the improvement of hydronephrosis. Many authors have described two-stage operations for such cases. Our findings revealed that one-stage operation, carefully preserving the blood supply to the ureter, would be an alternative surgical management for UP and UV strictures.
