Older living donors provide excellent quality kidneys: a single center experience (older living donors).Johnson SR, Khwaja K, Pavlakis M, Monaco AP, Hanto DW Division of Transplant Surgery, Department of Surgery, Beth Israel Deaconess Medical Center, Boston, MA 02215, USA. srjohnso@bidmc.harvard.edu BACKGROUND: The role of advanced age live donors remains controversial because of decline in glomerular filtration rate and perceived increased risks of perioperative complications. METHODS: A retrospective review of all live donor transplants performed from January 2000 to December 2003. RESULTS: Seventy-eight live donor transplants were performed during the period of review, 47 (60.3%) female and 31 (39.7%) male. Twenty-two (28.2%) of the donors were >50 yr old, 15 (68%) female and seven (32%) male. Living related donation was performed in 56 (74.4%) and unrelated in 20 (35.6%). Laparoscopic nephrectomy was performed in 29 (37.2%) and open nephrectomy in 49 (62.8%). More donors >50 underwent laparoscopic nephrectomy, 13 of 22 (59.1%) vs. 16 of 56 (28.6%). Overall patient and graft survival at 1 yr are 97 and 97%. One-year patient and graft survival is 100% vs. 96% and 100% vs. 96% in the older vs. young donors. Rejection occurred in nine of 78 (11.5%), but was not different between groups. Older donors had a reduced creatinine clearance 107.5 +/- 3.4 vs. 124.2 +/- 3.1 mL/min (p = 0.002) and a reduced clearance normalized for body surface area 60.6 +/- 3.6 mL/(min m2) vs. 70.2 +/- 2.6 mL/(min m2) (p = 0.045). Recipient serum creatinine was higher on postoperative day 1 in the older donor group 5.4 mg/dL vs. 4.4 mg/dL (p = 0.009). There was no difference in recipient serum creatinine at postoperative day 7, 30, 90, 180, 365 and 730. Donor serum creatinine was not different between groups on postoperative days 1, 7 and 30 but was higher in group 1 vs. group 2 on postoperative day 365, 1.26 +/- 0.26 mg/dL vs. 1.01 +/- 0.18 mg/dL (p = 0.020). CONCLUSIONS: Despite a reduced initial creatinine clearance, renal function is comparable in recipients of both young and old donor kidneys. Older donors had a slightly reduced serum creatinine 1 yr post-donation that warrants additional follow-up to determine if the observations continue. The introduction of laparoscopic nephrectomy may provide additional incentive for older donors to present for live donor nephrectomy. Published 8 September 2005 in Clin Transplant, 19(5): 600-6.
