Surgical complications in pediatric and adolescent renal transplantation

To report the surgical complications among our pediatric and adolescent renal transplants and to compare these results with other reported series in the literature. A total of 50 pediatric and adolescent renal transplants were included in this study. There were 30 boys and 20 girls with a mean age of 13 years (range 6 - 18 years). 70% of patients received their kidneys from living donors. Two patients underwent renal re-transplantation. Among the 52 transplantations, 17 surgical complications were encountered in 15(30%) patients. The incidence of urological and vascular complications was respectively 13.2% and 18.9%. These complications included vesico­ureteral reflux (9.4%), urinary leakage (3.8%), lymphocele (5.8%), peri-renal hematoma (1.9%), renal artery stenosis (3.7%), and thrombosis of the allograft (7.5%). The patients with vesico­ureteral reflux were treated by antibiotic prophylaxis. In four recipients, thrombosis of the allo­graft with subsequent graft loss occurred. The graft survival rate was 90% in 1 year, 77% in 5 years and 40% in 10 years follow-up. The patient survival rate was 94.4% in 1 year and 84% after 8 years follow-up. We conclude that surgical complications can be minimized if basic principles of careful transplant techniques are used. Prompt identification and treatment of any complication are critical for graft and patient survival.
