Prospective assessment of the impact of intraoperative diuretics in kidney transplant recipient surgery

Area of Science:

• Nephrology
• Transplantation Surgery
• Pharmacology

Background:

• Delayed graft function (DGF) is a complication following kidney transplantation.
• Intraoperative diuretics (furosemide, mannitol) are anecdotally used to prevent DGF, but evidence is limited.
• Practice patterns for diuretic use in kidney transplantation vary significantly.

Purpose of the Study:

• To evaluate the efficacy of intraoperative furosemide or mannitol in reducing DGF after kidney transplantation.
• To compare DGF rates between patients receiving diuretics and those not receiving diuretics.
• To assess secondary outcomes including graft function and potassium levels.

Main Methods:

• A cohort study design was employed.
• Adult kidney transplant recipients were allocated to receive furosemide, mannitol, or no diuretic intraoperatively before reperfusion.
• Primary outcome was DGF; secondary outcomes included 30-day graft function and perioperative potassium levels.

Main Results:

• 162 deceased donor kidney transplants were analyzed over two years.
• No significant difference in DGF rates was observed between individual furosemide, mannitol, and control groups.
• Pooled analysis of diuretic use (furosemide or mannitol) showed a significant reduction in DGF odds compared to the control group (OR 2.10, p=0.03).

Conclusions:

• Intraoperative administration of furosemide or mannitol may decrease the incidence of DGF in kidney transplant recipients.
• The findings suggest a potential benefit of using intraoperative diuretics to improve early kidney graft outcomes.
• A randomized controlled trial is recommended to confirm these findings and establish definitive evidence.
