More recently NSS has been reported for children with WT in the absence of absolute indications. In this present study we have prospectively assessed survival and local recurrence rates in children with unilateral localized Wilms tumor (WT) treated with either nephron sparing surgery (NSS) or simple nephrectomy with removal only of the perirenal fat adherent to the tumor surface. In this present study we have prospectively assessed survival and local recurrence rates in children with unilateral localized Wilms tumor (WT) treated with either nephron sparing surgery (NSS) or simple nephrectomy with removal only of the perirenal fat adherent to the tumor surface. MATERIAL AND METHODS Children presenting with unilateral Wilms tumor during the period Jan 2006 to Dec 2015 were prospectively randomized to undergo either simple nephrectomy along with removal of perirenal adherent fat or nephron sparing surgery. Treatment was administered to children according to the SIOP protocol 2001. RESULTS During the study period 28 children with Wilms tumor were operated. Thirteen children underwent simple nephrectomy, whereas the remaining 15 underwent nephron sparing surgery. The opposite kidneys were normal on USG and CT. The mean age at intervention was 44 months. Eight children had stage I disease and the remaining had stage II disease. No intraoperative complications were noted. The follow-up ranged 24–136 months and all children are alive. Only one child had lo- cal recurrence and underwent radiotherapy and chemotherapy. The was no difference in overall survival in both the groups. The post-operative GFR was significantly higher in children undergoing NSS, though the serum creatinine was within normal range in all children. The eventful survival was 96.42 %. CONCLUSIONS The oncological outcome of NSS for unilateral Wilms tumor is as good as simple nephrectomy with better preservation of renal function.
