Summary

This study looked at whether a simple urine test could predict scarring in kidney transplants, instead of using a needle biopsy. Researchers measured certain genetic markers in urine cells from 300 kidney transplant recipients over the first year after transplant. The goal was to see if these markers could forecast kidney damage early, helping doctors intervene sooner.
