Answer

Answer

The main objectives of staging Wilms tumors are the following:

  • To identify the origin of the tumor

  • To assess the extent of the tumor

  • To assess involvement of the renal vascular pedicle

  • To detect regional lymph node metastases

  • To detect bilateral Wilms tumors

  • To detect distant metastases

CT or MRI fulfills these objectives well. Although CT of the chest may be included in the primary staging procedure, most investigators from international studies of Wilms tumors have relied on chest radiographs to detect lung metastases.
