Study on the effect of unilateral donor kidney donated by child for adult recipient transplantation / 中华器官移植杂志

ABSTRACT

Objective:To evaluate the effect of unilateral pediatric kidney donation for adult kidney transplantation.Methods:Retrospective analysis was conducted on the cases of children who donated unilateral donor kidney for adult kidney transplantation recipients in our hospital, and those who were followed up for more than three years were included in this study. The body weight of the recipients in group A was ≤50 kg, and the body weight of the recipients in group B was ≤70 kg.The recipients were divided into 0-5 year old donor group (group A) and 6-17 year old donor group (B group). Clinical data, recipient/kidney survival, graft function and growth, and complications of the recipient were analyzed.Results:A total of 45 adult recipients were enrolled, including 12 in group A and 33 in group B. The renal survival rate at 3 years after operation was (100%, 96.9%)/(91.6%, 93.9%). One week after the operation, the early postoperative recovery of renal function in group B was better than that in group A, and the difference of serum creatinine was statistically significant ( P<0.05), while the difference of serum creatinine in other postoperative follow-up time points was not statistically significant ( P>0.05). Within a year, both groups of grafts continued to grow, reaching adult levels in one year. There was no statistical significance in the incidence of complications between the two groups ( P>0.05). The incidence of protein in the two groups was 33.3% and 6.1%, respectively, 1 case in each group still had proteinuria at 1 year after surgery, and only 1 case in the infant donor kidney recipient in group A had proteinuria at 3 years after surgery. Conclusions:Unilateral donor kidney transplantation from children can provide good results for adult patients with uremia by selecting suitable donors according to the weight of the recipient.
