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

36例の腎盂尿管腫瘍について臨床的検討を行った。1)性別は2対1と男子に多く, 平均年齢は男子66.4歳, 女子68.4歳であった。2)主訴は肉眼的血尿が66.7%と多かった。3)尿細胞診陽性率, 全尿において41.7%, カテーテル尿において61.1%であり, grade 2以上の移行上皮癌では, カテーテル尿においてほとんど陽性であった。4)組織型では移行上皮癌が72.2%と多かった。5)Kaplan-Meier法による生存率は, 全症例で1年生存率:80.4%, 3年生存率:65.4%, 5年生存率:54.5%, gradeによる生存率の差が一番顕著であった
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.
