[Wilms' tumor. The experience of the University Clinical Hospital of Zaragoza].
OBJECTIVE
The present study reviewed the records of patients with Wilms' tumor treated at the University Hospital of Zaragoza from January, 1980 to January, 1995.


METHODS
A retrospective study was conducted in 12 patients (5 boys and 7 girls) with Wilms' tumor, aged 9 months to 9.5 years, with special reference to the clinical symptoms and signs.


RESULTS
In 9 of the 12 cases, the tumor was localized to the left kidney and 3 cases had right-sided involvement. No patient showed an unfavorable histological finding, intraoperative rupture or the associated phenotypic manifestations that are frequently described in cases with this tumor type.


CONCLUSIONS
The mortality and survival rates are comparable with those reported by other authors in our country.
