Renal transplantation in children

INTRODUCTION: Various immunological, metabolic, and technical factors render pediatric recipients with end-stage renal disease unique from their adult counterparts. In addition, the potential for complications after renal transplantation is far greater in children than in adults. In this study, we retrospectively analyzed 83 pediatric recipients who underwent kidney transplantation at our institution from 1975 to 2004. MATERIALS AND METHODS: From November 1975 to December 2004, 1523 renal transplantations were performed at our institution with 56 procedures in 83 pediatric patients (44 boys and 39 girls; age range, 7 to 17 years; mean age, 14.9 +/- 2.2 years). RESULTS: Long-term follow-up revealed the following morbidities in 14 (16.3%) recipients: lymphocele in 7 (8.1%) patients, perirenal hematoma in 2 (2.3%), graft renal artery stenosis in 2 (2.3%), ureteral stenosis in 2 (2.3%), and ureteral anastomotic leak in 1 (1.2%). Six (7.2%) recipients with a functioning graft died during follow-up (five deaths were infection related, and the cause of one death was unknown). Five grafts failed (four for immunological reasons and one as a result of recurrent disease). The 1-, 3-, 5-year patient and graft survival rates were 98%, 93%, 92% and 91%, 78%, 67% for living related transplantations versus 98%, 91%, 90% and 92%, 76%, 65% for cadaveric transplantations, respectively. DISCUSSION: Better outcomes for renal transplantation in children may be obtained by strict adherence to precise surgical techniques, better immunosuppressive management, and early diagnosis/effective treatment of complications.
