Comparison of Native Ureteral Ligation and Open Nephrectomy for Pediatric Renal Transplantation

Purpose: In pediatric renal transplant recipients there are some indications for native nephrectomy, which can be performed before, during or after transplantation. Indications include massive proteinuria resistant to therapy, intractable hypertension, polyuria and chronic or recurrent kidney infections. Several scientific studies of adults have demonstrated a minimally invasive alternative to native nephrectomy, which consists of ligation of the native ureter without removing the kidney. We evaluated the safety and efficacy of this minimally invasive technique in pediatric recipients of renal transplantation.Materials and Methods: A total of 29 pediatric kidney transplant recipients underwent unilateral native ureteral ligation during renal transplantation between 2009 and 2013 (group A). In addition, a control group of 21 pediatric renal transplant recipients was enrolled who had undergone unilateral native nephrectomy between January 2005 and December 2008 (group B). Both groups were evaluated preopera...
