Histology of the biopsy sample taken during surgery is the gold standard for the diagnosis of wilms<unk> . Most of the<unk> s of the kidney have a favorable histology (90%).If anaplastic changes(3-7%) are found then the outcome is poor. If a case of wilms<unk>  is suspected in North America, then nephrectomy is done immediately. Contralateral kidney is also explored to check for disease and lymph node biopsies done. If<unk>  spill occurs then whole abdomen radiotherapy has to be done.
