Ureteral tumors were found in 4 out of 88 patients with bladder tumors who had been followed up at our clinic between July 4, 1984 and June 30, 1986. Radical nephroureterectomy and partial cystectomy were performed in 3 of them, and transurethral resection in the remaining one. The pathogenesis of the secondary ureteral tumors was discussed from the standpoints of implantation by vesicoureteral reflux, multicentricity, lymphatic or vascular spread and direct extension along the mucosa in these 4 cases. The ureteral tumor might have occurred in cases with multiple, recurrent or high grade bladder tumors and in cases with bladder tumors suffering from vesico-ureteral reflux. This study suggests that urine cytology, cystoscopy, retrograde cystography and excretory urography might be necessary in the cases of bladder tumors that had been treated with surgery with bladder preserved.
1984年7月4日至1986年6月30日在我们诊所接受随访的88例膀胱肿瘤患者中，有4例发现输尿管肿瘤。其中3例行根治性肾输尿管切除术和部分膀胱切除术，其余1例行经尿道切除术。从膀胱输尿管反流种植、多中心性、淋巴或血管扩散以及这4例沿黏膜直接蔓延的角度讨论了继发性输尿管肿瘤的发病机制。输尿管肿瘤可能发生在多发性、复发性或高级别膀胱肿瘤以及患有膀胱输尿管反流的膀胱肿瘤患者中。本研究表明，对于接受保留膀胱手术治疗的膀胱肿瘤患者，尿液细胞学检查、膀胱镜检查、逆行膀胱造影和排泄性尿路造影可能是必要的。
