Percutaneous management of grade II upper urinary tract transitional cell carcinoma: the long-term outcome.
OBJECTIVE
We report the long-term outcome of our experience with percutaneous treatment of grade II upper urinary tract transitional cell carcinoma.


METHODS
A total of 61 patients with transitional cell carcinoma of the upper urinary tract were treated percutaneously between 1984 and 1998. Of the patients 24 (39%) had grade II disease. Immediate nephroureterectomy was performed due to muscle invasive disease in 2 patients, bleeding in 1 and inability to resect the whole tumor in 1. Percutaneous resection was the actual treatment in 15 patients with stage Ta and 5 with stage T1 disease.


RESULTS
Recurrence was noted in 5 patients (25%), including 3 (20%) with stage Ta tumors and 2 (40%) with stage T1 disease after a median followup of 48 months (range 9 months to 12 years). All stage Ta disease recurrences were superficial. In 1 patient with a stage T1 tumor invasive and metastatic disease developed. Disease specific survival was 95% overall, and 100% for stage Ta and 80% for stage T1 disease. No tumor seeding was detected along the percutaneous tract.


CONCLUSIONS
Percutaneous surgery has proved safe and effective in treating superficial grade II upper tract transitional cell carcinoma. Offering an endoscopic approach electively to healthy individuals with a normal contralateral kidney seems viable.
