Background: Using living kidney donor's (LKD) organs is one of the strategies for making more transplants available. Results of kidney transplantation are superior when the kidney is obtained from a living donor. It is worthwhile to explain whether expanded criteria living donor kidney's acceptance is safe and offers satisfactory recipient's outcome. Aim: The aim of this study was to analyse living kidney donors and to propose the definition of expanded criteria living kidney donor.
Material/Methods: Eighty four live donor nephrectomies were performed
between 2000 and 2007. Mean donor age was 41.3 years. The donors were
predominantly female (59.2%). Open nephrectomy was performed in all
cases, usually left-sided (71.4%). In 36 (42.8%) cases the harvested kidney
was transplanted to a child. We analysed retrospectively the accessible data
of seventy six donors.
Results: We proposed risk factors that may affect both donor and recipient of the kidney. For each factor a specifi c number of points was assigned. Accordingly, a scale is suggested which defines expanded criteria living kidney donors. Kidney donors were divided into two groups-optimal donors (0-5 points) and expanded criteria donors (more than 5 points). Seven cases (9.2%) of expanded criteria living kidney donors were observed according to the proposed definition.
Conclusions: A comprehensive system of living kidney donors evaluation as
well as an assessment of influence of expanded living kidney donor factors
on short- and long-term donor outcome and recipient and graft survival are
necessary and shall be conducted in the future.
