Renal transplant anastomotic time-Every minute counts!

Area of Science:

• Nephrology
• Transplant Surgery
• Urology

Background:

• Anastomotic time is a controllable factor influencing delayed graft function (DGF) after renal transplantation.
• The precise impact of anastomotic time on DGF incidence is not well-established.
• Delayed graft function (DGF) is a significant complication affecting renal transplant outcomes.

Purpose of the Study:

• To quantify the association between anastomotic time and the incidence of DGF in renal transplant recipients.
• To identify controllable surgical factors impacting DGF.
• To provide evidence for optimizing surgical procedures to improve graft survival.

Main Methods:

• Retrospective review of 424 renal transplants (2006-2020), with a focus on 247 deceased donor transplants.
• Patients categorized into groups based on the presence or absence of DGF.
• Binary logistic regression analysis used for variables with p < 0.3 to determine significant predictors of DGF.

Main Results:

• Anastomotic time was significantly associated with DGF (OR 1.04 per minute), indicating a 4% increase in DGF risk for each additional minute.
• Donated Cadaveric Donor (DCD) status (OR 8.7) and donor terminal creatinine were also significant predictors of DGF.
• Surgical duration, specifically the time taken for vascular anastomosis, directly correlates with post-transplant graft function.

Conclusions:

• Anastomotic time is a significant, modifiable risk factor for developing DGF in renal transplantation.
• Reducing anastomotic time during surgery is recommended to minimize the incidence of DGF.
• Further research into surgical techniques to shorten anastomotic time may improve renal transplant outcomes.
