Analysis of the Factors Influencing Living Kidney Donation: The Experience in National Taiwan University Hospital

Introduction. Kidney transplantation provides a choice of active treatment for patients with chronic renal failure. However, the sources of organs are limited; therefore, living kidney donation is an alternative source. The regulation of organ donation in Taiwan stipulates that living organ donation is restricted to living related recipients. We sought to investigate factors that influenced or prevented individuals from living kidney donation in our center. Materials and methods. From January 2005 to December 2008, there were 266 potential candidates who underwent evaluation for living kidney donation in our center. Results. Among the potential candidates, most were spouses (n = 85, 31.9%), followed by parents (n = 67, 25.1%), siblings (n = 62, 23.3%), and children (n = 40, 15%). Eventually, 124 candidates (47%) completed organ donation, most of whom were siblings (n = 39, 31.5%), then parents (n = 38, 30.6%), spouses (n = 26), and children (11 = 18). Most donors were females, including mothers and sisters. The most frequent reason to not donate was unwillingness, due to potential influences on their health, economic stress due to suspension of their job, and objection of family members. In 34 candidates (23.9%), adverse health factors of potential candidates prohibited them from donating, including age, chronic medical illness, hepatitis carrier status, severe depression, or mental retardation. Among 59 potential donor-recipient pairs with incompatible ABO blood types or highly sensitized to potential donors, 22 candidates completed living kidney donation. Conclusion. Although laparoscopic nephrectomy for living kidney donation decreases the discomfort and hospital stay after donation, we can only promote living kidney donation if we can deal with the possible factors that prohibit candidates from living kidney donation, such as morbidity after organ donation, anxiety, or other factors. After analyzing those factors, we must also develop a protocol to closely follow the living kidney donors to ensure their health status and relieve their anxiety.
