[Chemoprophylaxis and endoscopical treatment of upper urinary tract tumors recurrences].
OBJECTIVE
Upper urinary tract tumors are a rare condition. We review our experience in the diagnosis of upper urinary tract tumors and their recurrences, emphasizing the management of recurrences.


METHODS
From January 1980 to June 2002 139 endourological procedures were carried out in 94 patients with the working diagnosis of upper urinary tract tumor.


RESULTS
The overall treatment failure rate was 18.7 with ureteroscopy being the least efficient technique.


CONCLUSIONS
In our experience, there is an indication for conservative endourological treatment in superficial low grade G1-2 tumors smaller than 2 cm.
