[Experience with uretero-neocystostomy in 338 kidney transplantations].

In 338 consecutive human kidney transplants since 1972 uretero-neocystostomy was performed in a typical manner. The technique is a modification of Leadbetter's ureterosigmoid anastomosis and it is used for all cases of ureteral reimplantation at our institution. The rate of operative complications belonging to the urinary tract is 4.8%. In 29% out of 31 reexamined patients a vesico-ureteral reflux to the transplant appeared. We believe that the demonstrated method is useful for reconstruction of the urinary tract in renal transplants.
