title: [Kidney transplantation in children weighing 11 kg or less].
abstract: OBJECTIVE
  To evaluate the outcome of kidney transplantation in children with low weight.
  
  
  METHODS
  Retrospective review of the medical records of patients weighing 11 kg or less that received kidney transplantation between 2001 and 2013 were retrospectively reviewed.
  
  
  RESULTS
  Fifty-nine kidney transplantations were performed in pediatric patients in our center, 12 of them were performed in patients weighing 11 kg or less (20%). The mean age of the recipient at the time of transplantation was 2 years (1-3.5); the mean weight was 9.4 ± 1.1 kg (8.3-11). The etiology of kidney failure was malformative in 42% of patients, inherited in 33%, glomerular in 8% and oiler etiologies in 17% of the patients. Two patients did not receive replacement therapy before transplantation (16.7%), nine received peritoneal dialysis (75%) and one of them hemodialysis (8.3%). Eleven of the grafts were from cadaveric donor (91.7%) and one of them from a living donor (8.3%). The mean donor age was 10 years (0.5-29). There was one case of acute graft thrombosis (8.3%) and one case of eventration requiring reoperation; there were no other major complications. Mean follow-up was 59 months (4-130). Overall survival (OS) was 100% at 1 year and 91.7% at 5 years. There was one death in a patient with mitochondrial disease with a functioning graft. Graft survival (GS) was 92% at 1 year and 75% at 5 years.
  
  
  CONCLUSIONS
  Kidney transplantation is the treatment of choice for end-stage kidney failure in the young child. It provides good results in terms of patient and graft survival.
