[A clinical study on transitional cell carcinoma of renal pelvis and ureter].

During the 9 years between 1983 and 1992, 36 patients with renal pelvic and ureteral tumors were treated in our hospital. There were 24 males and 12 females. The most common chief complaint was macrohematuria. Intravenous pyelography (IVP) revealed the finding of non-visualized kidney, filling defects and hydronephrosis in 99%. Histologically, 26 were found to have transitional cell carcinoma, one squamous cell carcinoma and one adenocarcinoma. The 5-year survival rate of this study was 54.5% according to the Kaplan-Meier's method. In our study the most important prognostic factor was histopathological grading.
