The goal is to see whether changes in the kidney's small blood vessels can help predict how well the transplanted kidney will work early after transplant, including whether delayed graft function may occur.\n\nInvestigators hope this technique can become a safe, noninvasive way to evaluate transplanted kidneys without needing as many invasive biopsies. It may also help doctors better assess donor kidneys at higher-risk of suboptimal functioning.",[25,26,27,28],"End Stage Chronic Renal Failure","Renal Transplant","Microvascular Changes","Microvascular Circulation",[30,31,32,33,34,35,36,37,38,39],"renal allograft","kidney allograft","kidney transplant","super-resolution ultrasound","lipid microspheres","renal microvasculature","kidney microvasculature","delayed graft function","Kidney Donor Profile Index","deceased donor kidney transplant","NOT_YET_RECRUITING","2026-06-08",{"date":43,"type":44},"2026-06-12","ACTUAL",{"date":46,"type":20},"2026-06-01",{"date":48,"type":20},"2028-06-30",{"name":50,"class":51},"Roderick Tan","OTHER",""]
