    Author: Duarte RJ, Dénes FT, Cristofani LM, Giron AM, Filho VO, Arap S.
    Journal: J Urol; 2004 Oct; 172(4 Pt 1):1438-40. PubMed ID: 15371863.
    Abstract:
    PURPOSE: We describe 2 cases of laparoscopic nephrectomy for unilateral Wilms tumor in children who underwent preoperative chemotherapy. MATERIALS AND METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.
