BACKGROUND: @entity3969 is the most common @entity703 in childhood. Preoperative treatment is still under discussion. The aim of this study was to determine, using our own @entity1 collective, the risk factors for and type of intraoperative complications which can occur. In addition, the influence of the surgical procedure and @entity5 size on the complications and survival rate was analyzed. METHODS AND MATERIALS: A total of 66 @entity1 with @entity3969 were retrospectively analyzed. Evaluation included histology, size of the @entity5 as well as neoadjuvant and adjuvant chemotherapy. The total survival rate over periods of 5 and 10 years postoperatively were analysed using Kaplan-Meier survival probabilities. RESULTS: All @entity1 underwent radical nephrectomy: 63 using the transperitoneal and three the lumbar approach. The @entity5 had a mean size of 9.8 cm (range 2.5-20.0). Twenty @entity1 (30.3%) received neoadjuvant chemotherapy for @entity5 reduction, while 46 @entity1 underwent surgery without preoperative chemotherapy. Complications occurred in eight @entity1 (15.2%). In two, a the @entity5 ruptured under surgery, four @entity1 developed an ileus and two suffered @entity1167 . One @entity1 had postoperative @entity4372 and another an incisional @entity547 . All complications occurred with a @entity5 size >5 cm or in the @entity1 group without neoadjuvant chemotherapy. The 10 year survival rate was 89.4%. CONCLUSIONS: The risk of complications is associated with the local size of the @entity5 . Through @entity5 reduction, neoadjuvant chemotherapy influences the expression of the such complications. Transperitoneal @entity5 nephrectomy is the method of choice in surgery for @entity3969 .
