[Urographic and cineradiographic follow-up studies in ureteral stenoses following radical pelvic operations (author's transl)].

The results of 19 urographic follow-up studies 6-15 months following vaginal or abdominal radical pelvic operation are reported. Compared to the first follow-up studies 1-7 weeks after the operation which always showed stenosis of the pelvic ureters with various degrees of urinary retention about one half of the cases showed improvement of the stenoses and normalization of the ureteral function later on even when marked urinary retention was found earlier on. Seven cases showed marked improvement. In these seven cases the dynamics of the ureteral function was studied by cineradiography. The results of this investigation are discussed. A deterioration of the urinary retention was observed in only 2 cases. An adverse effect of preoperative or post-operative radiotherapy on the prognosis of ureteral stenosis was not observed.
