原发性输尿管肿瘤较少见。国内自1951年至1965年共报告12例,其中恶性4例,良性3例,息肉5例。我院在1963—1974年间共收治6例,均为恶性。由于我们对此病缺乏认识,术前确诊率低,手术方式欠妥,教训颇深,特报告如下。 Primary ureteral tumors are rare. A total of 12 cases were reported in China from 1951 to 1965, of which 4 were malignant, 3 were benign and 5 were polyps. In our hospital from 1963 to 1974 were treated 6 cases were all malignant. Because of our lack of understanding of the disease, the low preoperative diagnosis, surgical defects, lessons learned, special report is as follows.
