| c. |
Abdominal ultrasound gives the best information about extensiveness of the tumor. Flat and erect x-rays of the abdomen may show linear calcifications, but are not as helpful as ultrasound. Intravenous pyelogram is rarely useful and voiding cystourethrogram is not indicated in the evaluation of Wilm’s tumor.
