[Renal transplantation in children. Surgical aspects]

Abstract

The renal transplantation in children has some specificities: urologic anomalies (vesico ureteral reflux, posterior urethral valves) are frequently the cause of the renal failure, and necessitate a thorough surgical preparation before transplantation (nephrectomy, reconstitution of urinary tract). The child must have a sterile, compliant and continent urinary tract on the day of the operation. In small children (< 15 kg), it is often necessary to operate through a transperitoneal incision, especially if the donor is an adult: the anastomoses will then concern the aorta and vena cava. The results are good, even better than in adults, except for very young children (under six years of age). Transplantation with living related donor (LRD) give the best results. Currently, the graft survival is 87% to 90% after three years with LRD, versus 65 to 77% with cadaveric donors.
