[Replacement of the ureter by the appendix in the treatment of a tumour of the excretory tract of a single kidney (author's transl)].

The authors report a case of appendiculoplasty of the right ureter within the context of the course of a bilateral tumour of the excretory tract necessitating conservative surgery with a single remaining kidney. The result is good at three years. The literature is reviewed, there being 13 published cases. Of the 10 cases with a follow-up of more than 1 year, there were only 5 good results and stenosis may develop several years after the reconstructive procedure.
