Objectives: To evaluate the
necessity of exploring the contralateral kidney in the surgery of Wilms’
tumor.
Materials: From Oct. 1979 to Dec.
1994, 81 Wilms’ tumors were operated in our hospital followed by
chemotherapy or radiotherapy. According to the staging criteria of NWTS,
there were 34 in stage I, 23 in stage II, 15 in stage III, and 6 in stage
IV, only three patients were stage V. All patients were evaluated by
ultrasound, CT scan, and IVU preoperatively, 11 patients also by MRI.
Unilateral and Bilateral (only 3 cases) Wilms’ tumors were diagnosed in 76
patients before the surgery. Other five children were suspected as
Neuroblastomas (in 4 tumors) and Teratoma.
Results: 78 patients were followed
for 6-20 years. The 5 year survival rate was 79.49%. The patients died of
metastasis, recurrence and complications from chemo- or radiotherapy, not
any single case was found to have a contralateral Wilms’ tumor.
Conclusion: Since the well
developed technique of imaging, it is less necessary to explore the
contralateral kidney during the surgery of Wilms’ tumor.
