【 摘 要 】

Due to a significant improvement in quality and quantity of life in most patients with end stage renal disease, kidney transplantation proved to be the best form of cost-effective treatment. The aim of this study was to analyze donor-recipient (n=2550) demographic characteristics associated with kidney transplantation in Isfahan Province/Iran. Demographic and clinical data were recorded in d-base and analyzed using SPSS for windows. A total of (recipient vs donor), 468 vs 63 females and 949 vs 1070 males were identified. The mean age of recipient vs donor was 42.5 ± 15.4 (range 2–87) vs 29.8 ± 6.1 (range 1–75) years (p<0.05). Age in 93% of donor was ranged between 20 to 40 years and in the 92% of recipients age was ranged between 20 to 70 years. With a significant p<0.006, the mean age of kidney transplanted recipients was higher in males than in females. The mean hospital stay was 20.6 days (range 1 to 180 days). In conclusion there was a significant difference between recipient and donor related to mean age and gender. An increase in the number of transplanted kidney recipients from 2008 to 2016, recommended the benefit of further study toward the impact of time to create the vascular anastomoses, graft survival and evidence-based pharmacotherapy strategy in Isfahan, Iran .
