Lee, Young Jai; Lim, Su Kil

Abstract

In order to determine its accuracy the authors conducted cytologic examination on patients found to have urothelial carcinoma by cystoscopy, histopathologic and radiological examinations at the Department of Urology, Catholic Medical College, from January 1971 to August 1981. The results were as follows: 1. Age distribution of the urothelial carcinomas is from 33 to 80 years age and the most frequent age group is 40 to 59 years age. The male: female ratio is 4.3:1. 2. Of the 32 patients, 4 cases (12.4%) were negative, 14 (43.8%) suspicious and 14 (43.8%) positive reports. 3. No significant correlations were found between the urine cytology and histologic grade, but the higher cytologic class had tendency to have the higher histologic grade. 4. In the aspect of the tumor size and cytology, large sized tumor had showed positive findings more frequently than that of, smaller one, but it showed high accuracy rate (77.8%) when small sized tumors were multiple.
