Objective: To evaluate the results of percutaneous endoscopic treatment of renal pelvic transitional cell carcinoma (TCC).
Patients and methods: Ten patients (median age, 70 years; range 56-86) with a renal pelvic TCC were treated by percutaneous endoscopic resection. Seven had a normal contralateral kidney and were treated electively.
Results: Follow-up was from 3 to 77 months. There was one recurrence locally and one recurrence in the bladder. There have been no recurrences in the nephrostomy tract.
Conclusion: We have shown that percutaneous resection of intrarenal TCC is a possible and safe technique. Further follow-up is needed to confirm its safety.
