Toward a Standardized System for Reporting Surgical Outcome of Pediatric and Adolescent Live Donor Renal Allotransplantation

Purpose: There is a lack of a standardized reporting methodology for surgical complications of pediatric renal transplantation. We applied Martin criteria and the modified Clavien-Dindo classification in pediatric renal transplantation.Materials and Methods: We retrospectively reviewed the charts of 447 patients 20 years or younger who underwent renal transplantation between March 1976 and January 2011. Martin criteria were fulfilled and complications were graded according to the modified Clavien-Dindo classification. For early complications grades I and II were considered low grade and III to V high grade. A similar grading system was adopted for late complications.Results: A total of 84 early complications (18.5%) occurred in 77 transplant recipients (17%). Of grade I complications 37 (8.1%) were asymptomatic lymphoceles. Grade II complications were observed in 2 patients (0.4%). Grade IIIa complications included aspiration of hematoma (1 case), percutaneous nephrostomy fixed for ureteral obstruction (3...
