We describe 2 cases of laparoscopic nephrectomy for unilateral Wilms tumor in children who underwent preoperative chemotherapy.Two children with unilateral nonmetastatic Wilms tumor included in the International Society of Pediatric Oncology 2001 protocol were preoperatively treated with vincristine/actinomycin D and subsequently underwent laparoscopic nephrectomy and lymph node sampling. A 5 and 10 mm trocar transperitoneal approach was used in each case. The tumor was extracted without morcellation through a 4 cm Pffannensteil incision.The 2 tumors were completely removed as well as lymph node samples. Intraoperative bleeding was minimal (50 ml). The postoperative period was free of complications and patients were discharged home after 3 days.Laparoscopic nephrectomy for Wilms tumor is feasible in children after chemotherapy. It is a safe procedure and it allows the complete surgical approach required to treat this tumor. Longer followup is necessary to evaluate long-term results and more cases are necessary to compare the results of laparoscopic techniques with those of open surgical procedures.
