We preoperatively diagnosed four cases suspected as malignant urothelial tumor of upper urinary tract using a rigid ureteroscope. In three cases of ureter tumor, biopsy was successful and showed low grade malignancy. Nephroureterectomy was performed in two cases with upper ureteral tumor. The tumor was fulgurated ureteroscopically in a case of lower ureteral tumor. In one case of renal pelvic tumor, biopsy was unsuccessful though the tumor was observed as a papillary configuration. Successively, biopsy using a flexible ureteroscope was performed and the tumor was treated by fulguration. Ureteroscopy is very useful for preoperative diagnosis of ureteral tumor and selection of treatment.
我们使用硬性输尿管镜术前诊断出4例疑似上尿路恶性尿路上皮肿瘤的病例。在3例输尿管肿瘤病例中，活检成功，显示为低级别恶性。2例上段输尿管肿瘤患者接受了肾输尿管切除术。1例下段输尿管肿瘤患者通过输尿管镜进行了电灼治疗。1例肾盂肿瘤患者，尽管观察到肿瘤呈乳头状形态，但活检未成功。随后，使用软性输尿管镜进行活检，并通过电灼治疗肿瘤。输尿管镜检查对于输尿管肿瘤的术前诊断和治疗选择非常有用。
