Minimally invasive surgery (CMI) for the treatment of malignant tumors in children begins to have a role for selected cases and reaches similar results than open surgery. We show our first two cases of Wilms tumor treated by laparoscopy describing patients and technique. Three-year-old girl with macroscopic hematuria is diagnosed of 8 cm mass in the left kidney suggesting Wilms tumor. After 4 weeks of chemotherapy she went under laparoscopic nephroureterectomy. The histological result was Wilms tumor. Chemotherapy was completed seven more months. Five-year-old patient with abdominal pain is diagnosed of renal right mass suggesting Wilms tumor. After 4 weeks of chemotherapy the laparoscopic nephroureterectomy was performed. The histological result was Wilms tumor. Treatment was completes with postoperatory chemotherapy. After 1 year follow-up both patients have clinical and radiological absence of disease. The CMI in selected cases of Wilms tumor fulfills successfully the aims of the surgical treatment.
