A 72-year-old male patient underwent antegrade percutaneous resection of a solitary and papillary tumor in the lower calyx of left kidney. He had undergone right nephroureterectomy one month previously due to right nonfunctioning kidney caused by right ureteral carcinoma. Percutaneous electroresection of the tumor was performed after puncture of a lower calyx. Pathological findings revealed a grade 2 transitional cell carcinoma. Second look biopsy was done on the 11th postoperative day, which showed no residual tumor pathologically. Continuous instillation of mitomycin-C 50 mg/50 ml saline with 40 cm H2O pressure for one hour was done through the nephrostomy catheter once a day, totally 7 days as an adjuvant therapy. No side effect was noticed. Cytological, radiographic studies were negative 24 months after the treatment. We discuss the indication and technical aspect of percutaneous approach to renal pelvic carcinoma.
一名72岁男性患者接受了顺行性经皮切除左肾下盏的孤立性乳头状肿瘤手术。他一个月前因右侧输尿管癌导致右肾无功能而接受了右肾输尿管切除术。在穿刺下盏后进行了肿瘤的经皮电切术。病理结果显示为2级移行细胞癌。术后第11天进行了二次活检，病理显示无残留肿瘤。通过肾造瘘导管每天一次以40 cm H2O压力持续滴注50 mg丝裂霉素-C溶于50 ml盐水中，共7天作为辅助治疗。未观察到副作用。治疗24个月后细胞学和影像学检查均为阴性。我们讨论了经皮治疗肾盂癌的适应证和技术方面。
