Autonephrectomy, or kidney removal, occurred in 33.3% of pediatric neuroblastoma patients with renal vessel encasement. Meticulous surgical dissection is crucial to prevent kidney damage during tumor removal.

Area of Science:

  • Pediatric Oncology
  • Surgical Oncology
  • Nephrology

Background:

  • Intra-abdominal neuroblastoma is a common pediatric malignancy.
  • Renal vessel encasement presents surgical challenges during tumor resection.
  • Autonephrectomy, the spontaneous loss of kidney function, is an underreported complication.

Purpose of the Study:

  • To evaluate the incidence of autonephrectomy in pediatric neuroblastoma patients with renal vessel encasement.
  • To identify factors contributing to autonephrectomy in these cases.

Main Methods:

  • Retrospective analysis of 39 pediatric neuroblastoma patients undergoing surgery for intra-abdominal tumors with renal vascular encasement.
  • Definition of renal vascular encasement: tumor abutment >180 degrees of the vessel wall.

  • Assessment of renal function via preoperative imaging, intraoperative findings, and postoperative scans.

    • Main Results:

    • 14 out of 39 patients (35.9%) exhibited renal vessel encasement.
    • Four out of 12 patients (33.3%) with encasement developed autonephrectomy at a median of 3.25 months post-surgery.
    • Eight out of 12 patients (66.7%) maintained ipsilateral renal function despite extensive dissection.

    Conclusions:

    • Autonephrectomy is a significant, albeit infrequently reported, complication in neuroblastoma surgery involving renal vessels.
    • Careful surgical technique and meticulous dissection around renal vasculature are essential to minimize the risk of kidney damage.
    • Improved surgical outcomes and patient safety can be achieved through attention to these critical structures.
