Abstract

Background and objectives: En bloc kidney transplantation (EBKT) from pediatric donors into adult recipients increases the donor pool. However, this surgical procedure is not widely performed in many transplant centers. To evaluate the long-term outcomes of EBKT from pediatric donors into adult recipients in a single center.

Material and methods: Retrospective analysis of 42 patients who received pediatric cadaveric EBKT in our center since 1999. Median follow-up period was 73 months (5-233) in which renal function tests were taken and complications registered.

Results: We have performed 42 EBKT from pediatric donors into adult recipients in our center. The recipients' age was 44.1 ± 11.8 years. Pediatric donors were 22.4 ± 14.7 months old and weighted 11.3 ± 3.6 kg. Cold ischemia time was 15.7 ± 4.5 h. During a median follow-up of 73 months, 35 patients (83.3%) had graft survival with excellent function (first-year serum creatinine levels of 0.99 ± 0.25 mg/dl). There were seven graft losses (16.7%) in the immediate postoperative period (four cases of vascular thrombosis, one anastomosis dehiscence and two cortical necrosis).

Conclusions: The pediatric en bloc renal graft transplantation into adults is a safe technique with excellent medium- to long-term functional performance. The vast majority of significant complications leading to graft loss were reported in the immediate postoperative period. A good selection of donors and recipients as well as an adequate surgical technique are essential to minimize the occurrence of adverse events.
