Expanding the Living Donor Pool "Second Act": Laparoscopic Donor Nephrectomy and ABO-Incompatible Kidney Transplantation Improve Donor Recruitment.

ABSTRACT

BACKGROUND: To safely expand our living donor pool, we recently decided to work on 3 areas analysis of causes of exclusion of potential donors, the results of which we recently published, introduction of laparoscopic donor nephrectomy (LDN), and ABO-incompatible (ABOi) transplantation. We sought to determine the impact of the new strategy on living donor recruitment and transplantation during over a 10-year period at a single institution. METHODS: From January 2005 to September 2014, we evaluated 131 living donors. Of these, 80 (61%) were genetically related, 51 (39%) unrelated, 119 (91%) ABO compatible (ABOc), 12 ABOi (9%). The analysis was divided into 2 eras era 1, 2005-2010 (n = 53) included the use of open lumbotomy and acceptance of ABOc only; and era 2, 2011-2014 (n = 78), which saw the introduction of LDN and ABOi transplantation. RESULTS: Forty-five (34%) potential candidates successfully donated, 67 (51%) were excluded, and 19 (15%) were actively undergoing evaluation. Overall, 53 potential donors were evaluated in era 1 (8.8 donors/year), 78 in era 2 (19.5 donors/year). There were fewer excluded donors in era 2 vs era 1 (62% era 1 vs 44% era 2), and living donor kidney transplantation (LDKT) significantly increased in era 2 vs era 1 (3.3/year era 1 vs 7.1/year era 2). The establishment of an ABOi LDKT program led to a 15% increase of evaluations in era 2 (12/78 donors). CONCLUSIONS: LDN along with ABOi LDKT allowed for an improvement in recruitment of living donors and corresponding LDKT.
