correct answer

E Sampling of lymph nodes from the renal hilum, paraaortic and paracaval regions, and any suspicious nodes​​

 

Lymph node sampling is a required component of nephrectomy for Wilms tumor. Inadequate node sampling may lead to improper staging and therapy. A minimum of five nodes should be sampled, but obtaining six to ten nodes may reduce the false negative rate.
