Nephron sparing surgery (NSS) is increasingly utilized to treat patients with bilateral Wilms tumor. We present a case of NSS planning using a three-dimensional computerized and printed model of both kidneys with anatomical structures of interest (parenchyma, renal pelvis, major calyx, renal artery, renal vein, and tumor). This model allowed a better understanding of the anatomic relation between the tumor and the normal kidney on each side, improving the surgical planning and the preoperative discussion with the patient's family.
Keywords: bilateral Wilms; model; printed; three-dimensional.
