Long term outcomes after concurrent ipsilateral nephrectomy versus kidney-sparing surgery for high-risk, intraabdominal neuroblastoma

Retrospective study of 58 high-risk intraabdominal neuroblastoma patients comparing concurrent nephrectomy (n=6) versus kidney-sparing surgery (n=52). While nephrectomy reduced long-term kidney function (eGFR 90 vs 127 ml/min/1.73m²), it showed no survival advantage or difference in recurrence rates, supporting kidney preservation when feasible.
