title: [Percutaneous resection of renal pelvic carcinoma: a case report].
abstract: 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.
