Organ-preserving surgery in patients with urothelial tumors of the upper urinary tract.

: The Austrian Urological Oncology Group reports on 55 organ-preserving operations in 52 patients with tumors of the upper urinary tract epithelium. The data were gathered from 12 urological departments in the country. There was no evidence of distant metastases in any of the patients at the time of surgery. The observation period ranged from 0.5 to 12 years. 69.2% (36 of 52) of the patients were alive and recurrence-free at the time of data collection, after a mean observation period of 41.4 months. 9.6% died for reasons other than cancer after an average of 18.8 months, and 21.2% were still alive with or had died due to recurrent tumors. The recurrence rate after open surgery was similar in tumors of the upper ureter or pelvis (15.3%) as in tumors of the lower ureter (17.6%). After endoscopic treatment 4 of 9 patients showed recurrences. 92% (22 of 24) of the patients with no compelling indication for organ-preserving therapy were alive and recurrence-free or had died due to other causes. Therefore organ-preserving surgery appears to be appropriate in tumors of the upper urinary tract epithelium.
