Study Overview

Brief Summary

The anastomotic and peripheral stenosis of the transplanted kidney artery is one of the most important causes of graft failure in renal transplantation. The injury of vascular intima and the formation of microthrombosis may play a significant role in the stenosis of transplanted renal artery of recipients. Inhibiting this process with aspirin may protects against the stenosis of transplanted renal artery.

This is a prospective, randomized, controlled, clinical trial to investigate the efficacy and safety of prevention of renal artery stenosis in recipients.
