Boari flap vesicocalycostomy: a salvage drainage procedure for complete ureteric stricture and pyelocalyceal fistula.

To increase the working knowledge on how to drain a transplanted kidney via the use of a Boari flap as a salvage procedure. A female with a transplant kidney had complete obstruction at the ureteropelvic junction and multiple strictures of the ureter causing deterioration of the graft function. Surgery was the only way to successfully drain the obstructed kidney, but conventional methods were not possible due to dense fibrosis around the kidney. A Boari flap to the lower pole calyx of the transplant kidney was therefore employed. A Boari flap vesicocalycostomy is a potential method available to the transplant surgeon to successfully restore graft function in a case where the transplant or native ureter is unsalvageable.
