[Value of urinary cytology in urological diagnosis. Report after ten years (author's transl)].

Since January 1970 to August 1981 2298 urinary cytological examinations on 1228 patients were done in the urological clinic and policlinic of the university of Munich. With this material we have examined the value of this method in urologic practice. Increasing numbers in urinary cytology point out the confidence that is placed in this technique. Primary tumors of the urinary tract can be recognized cytologically with high reliability. The diagnosis is more difficult during the first 6 months postoperatively or during chemotherapy.
