Overview

Retrospective cohort study reveals early kidney transplant scintigraphy predicts graft survival, suggesting enhanced patient care protocols.

Key Points

  • Evaluate if early post-kidney transplant scintigraphy predicts long-term graft survival.
  • Retrospective cohort study of kidney transplantations at a single academic center from 2015-2019.
  • Included patients underwent 99mTc-MAG3 scintigraphy within 48 hours post-transplantation.
  • Cox proportional hazards regression analysis was used to assess graft survival, adjusting for key variables.
  • Among 317 patients, 25.9% experienced delayed graft function (DGF) with higher rates in lower grade renograms.
  • Grade 4 renograms had a significantly higher risk of graft loss (HR: 3.15; 95% CI: 1.34–7.40; p=0.008).
  • Findings suggest integrating early scintigraphy into risk stratification for long-term graft outcomes.
