Brief Summary

Kidney transplantation from living donors has been shown to carry many benefits over deceased donor transplantation. Because of benefits such as shorter waiting times and improved outcome for transplant recipients, living kidney donation accounts for an increasing number of kidney transplants nationwide. Most published studies about living kidney donation demonstrate that the procedure is safe, but they also emphasize concerns that long-term data on live donor outcomes are insufficient. In particular, data concerning the extent of renal function decline after donation are inadequate. This study will measure glomerular filtration rate (GFR) in previous living donors and aims to more accurately describe renal function after kidney donation.

Outcome Measures

Primary Outcomes (4)

  • Change in measured GFR from before donor nephrectomy compared to early (within first 2 years) after donor nephrectomy.

    Throughout study

  • Change in measured GFR from early after donor nephrectomy compared to late donor nephrectomy. Change in measured GFR from early to late after donor nephrectomy stratified by: time since donation, hypertensive donors, obese donors, and age of donors

    Throughout study

  • Differences in measured GFR in black donors compared to white donors matched by age, sex and time from donation

    Throughout study

  • Incremental differences between measured GFR and estimated GFR before donor nephrectomy, early after donor nephrectomy, and late after donor nephrectomy

    Throughout study

Secondary Outcomes (2)

  • Differences in measured GFR between hypertensive donors and normotensive donors

    Throughout study

  • Differences in measured GFR between donors with familial history of renal disease (LRD) and donors without familial history of renal disease (LURD)

    Throughout study

Study Population

individuals participating in DAIT RELIVE-04 who donated a kidney at the Mayo Clinic-Rochester, University of Minnesota, or the University of Alabama

You may qualify if:

  • Underwent unilateral donor nephrectomy between 5 and 50 years ago; but no later than June 30, 2005 at Mayo Clinic or University of Minnesota
  • Alive at the time of study recruitment
