Management of total ureteral loss after kidney transplantation.

Loss of the ureter after transplantation is uncommon and is difficult to manage. A Boari flap can be used to replace the ureter. The authors describe two patients with total ureteral loss. In each a Boari flap was used, to create a pyelocystostomy in one case and a calicecystostomy in the other. Both patients had greatly reduced serum creatinine levels and no urinary tract infections 14 and 18 months, respectively, after operation.
