Intraoperative diuretics during deceased-donor kidney transplants

Official title: A Pilot Randomized, Surgeon-blinded, Trial of Intraoperative Furosemide Versus Mannitol Among Deceased Donor Kidney Transplant Recipients

Run by London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's · NCT07726134 · Data updated 2026-11-12

This trial tests whether using furosemide or mannitol during kidney transplant surgery affects delayed graft function in adults receiving a deceased-donor kidney.

Is this trial a fit for you?

Likely a good fit

Adults 18 years or older undergoing a deceased-donor kidney transplant (NDD or DCD) who consent to participate.

Probably not a fit

Patients who do not experience delayed graft function or who have contraindications to either diuretic may not derive benefit.

What this trial studies

This single-center, prospective, randomized pilot study compares two intraoperative diuretics—furosemide and mannitol—in adult recipients of deceased-donor kidney transplants. Participants are randomized 1:1, stratified by donor type, and surgeon-blinded to the diuretic used. The goal is to determine if one agent more effectively reduces the risk of delayed graft function, defined as dialysis within the first seven days post-transplant. DGF is a common complication linked to longer hospital stays and higher rejection risk, potentially impacting long-term graft survival. The trial will enroll up to 240 participants at London Health Sciences Centre to inform future practice and larger studies.

Why it matters

Potential benefit: If one diuretic proves superior, it could reduce delayed graft function and improve short- and long-term kidney graft outcomes.

How similar studies have gone: There have been decades of intraoperative diuretic use, but no prospective randomized comparison between furosemide and mannitol prior to this trial.
