[Experience obtained from use of endoprotheses in treatment of ureterostenosis (author's transl)].

Reported in this paper is the authors' own experience obtained from treatment of 25 cases of severe ureterostenosis, using plastic endoprotheses (splints), according to a technique proposed by Schmitz and Hegemann, 1966. Ascending infection did not occur at all. The disputed method may be used in exceptional situations to get to grips with postsurgical or postradiological ureterostenosis, a condition not fully avoidable yet. Such exceptions may be claimed for patients to whom uretero-surgery would be an intolerable stress or for those on whom pharmacotherapy, using glucocorticoids and antibiotics, has failed.
