Granuloma of the distal extremity of the ureter in kidney transplantation.

A granuloma of the distal extremity of the transplanted ureter was diagnosed in 8 of 180 patients operated on according to the Lich-Gregoir technique. This lesion was not observed in 116 patients with Politano-Leadbetter ureterovesical anastomosis nor in 61 patients with a ureterocystostomy constructed according to the technique of De Campos Freire et al. This complication seems to be specific of the Lich-Gregoir technique.
