原発性尿管癌の1例および本邦報告294例の統計的観察

Abstract

A case of ureteral carcinoma on the right side was presented. The patient was a 64-year-old man, and resection of the lower -part of the ureter including tumor and uretero-cystoneostomy were -performed (Fig. 1, 2). Histologically, the tumor was transitional cell carcinoma, gradeII(Fig. 3, 4). Postoperatively the patient has been good up to 5 months. In Japan, 294 cases of the primary ureteral carcinoma have been reported since 1935. Statistical survey of them was made. 1) Men are more often affected than women (ratio 208: 71) (Table 1). 2) The age ranged from 33 to 89 years with the greatest incidence in the fifth, sixth and seventh decades (Table 1). 3) The lower third of the ureter is affected in 53% (Table 1). 4) Transitional cell carcinoma and papillary carcinoma are common (Table 4). 5) Many kinds of operations have been employed. Nephroureterectomy or nephroureterectomy and segmental cystectomy occupied 80% of all the surgeries (Table 5).
