The impact of the angioplasty of the renal artery and cold ischemia time in kidney transplantation on graft function.

The aim of this study was to analyze the benefit of the patients after renal transplantation with an assessment of the significance of different surgical techniques in patients with renal transplantation (not only from the dead but also the living donors) with multiple arteries. 457 patients with end stage renal disease (ESRD) in the treatment using the extracorporeal elimination method (haemodialysis, or peritoneal dialysis), who in the period from 2005 to 2015 had a kidney transplant were included in our retrospective study. Our results confirm that the patients after kidney transplantation with cold ischemia time more than 12 hours have 2.5 times higher risk of delayed onset, possibly failure of graft function compared to those with cold ischemia time less than 12 hours. This confirms our experience that the best option for the patient to achieve a stable graft function with long-term perspective is cold ischemia time of less than 12 hours and the realisation of renal artery angioplasty. In this case, the risk of delayed onset of transplanted kidney function or graft failure decreases 4.5 times compared to the respondents with cold ischemia time more than 12 hours without carrying out arterial angioplasty (Tab. 1, Fig. 4, Ref. 16).
