Influence of surgical complications on graft and patients' survival after a kidney transplantation according to donors' age. 
The aim of this study was to determine a frequency and a type of early and late surgical complications in kidney transplantation, their impact on renal graft survival among 80 patients, 54 (67.5%) males and 26 (32.5%) females who had undergone a living and cadaveric kidney transplant at the Surgery Center in Tuzla in the period from 15.09.1999 until 31.12.2008.  The subjects were divided into two groups according to donor age, younger and older than 55.  A significantly higher incidence of early rather than late surgical complications was observed in an experimental group (p=0.001, and p=0.77, respectively).  There was a statistically significant difference in the length of graft survival (p=0.004) and the number of deaths (p=0.038).  Older age of kidney graft donor had an impact on the occurrence of early surgical complications and no influence on the occurrence of late surgical complications.  Fatal outcome after kidney transplantation was significantly higher in patients who received grafts of elderly people.
