title: Surgical treatment of pediatric retroperitoneal tumors with invasion of major blood vessels: a single-center experience.
abstract: BACKGROUND
  This study assessed operative experiences with common pediatric retroperitoneal tumors invading major blood vessels.
  
  
  METHODS
  Forty-seven pediatric patients with retroperitoneal tumors were enrolled. They included 22 neuroblastomas, 6 gangliocytomas and 19 Wilms' tumors, and underwent primary surgical resection after vascular skeletonization and manipulations of involved vessels.
  
  
  RESULTS
  In the above tumors, the one-stage gross total resection rates of, respectively, 95.45%, 100% and 100% were obtained. There was only one complication, namely post-operational early acute renal failure that recovered with dialysis. There were no deaths.
  
  
  CONCLUSIONS
  Vascular skeletonization and other vessel manipulations prior to surgery improve the gross total resection rates of pediatric retroperitoneal tumors.
