Living‐unrelated kidney donation: a single‐center experience

Abstract

For 140 consecutive renal transplants performed from January 1995 to October 1997, 25 (18%) were from living-unrelated donors (15 women, 10 men, aged 25-63, mean 43 yr). All donors had pre-transplant imaging evaluation of renal anatomy following renal function assessment (minimal creatinine clearance 75 cm3/min). Admission to the hospital on the day of donation preceded nephrectomy under general anesthesia using an anterior flank, extra-retroperitoneal approach (no rib resection). Post-operative epidural pain control was used for all but 1 donor. The 25 kidney donors were hospitalized for 2 (n = 1), 3 (n = 12), 4 (n = 7), or 5-8 d (n = 5) (average 3.9 d) and had a mean hospitalization charge of $15,501 (range $10,808-$29,579). One intra-operative hemorrhage required transfusion; 1 late neural-related pain syndrome required outpatient wound exploration. Two kidneys were lost: a husband recipient from repetitive acute rejections at 3 months; a friend recipient from chronic rejection at 2.5 yr; both await cadaver transplant. The other 23 kidneys are functioning with a mean serum creatinine of 1.8 (range 1.0-3.3) at 3-36 months (patient survival 100%; graft survival 92%). While most donors were spouses (8 husbands and 10 wives), friends, distant cousins, in-laws, and adoptive relatives did well as donors and recipients. Transplantation may increase by 20% or more at centers which encourage broad application of living donor nephrectomy.
