Abstract

Background: Delayed graft function, involving at least one dialysis session in the first week post-renal allotransplantation, is a growing early complication of kidney transplantation.

Aim: To examine the relationship between delayed graft function and resistive index in renal graft recipients (KTR).

Patients and methods: This cross-sectional study was conducted on 30 renal transplant recipients who received kidney grafts in Cairo Fatemic Hospital (Unit of Kidney Transplantation) in collaboration with Bab Al-Shareia University Hospital over one year from August- 2023 to August- 2024. Cases were divided into two groups: The study group, which included 15 cases having delayed graft function (DGF), and the Control group, which included 15 cases having no DGF.

Results: There was a statistically significant difference between no-DGF and DGF regarding cold ischemia time, mean arterial pressure, operative time, and length of hospital stay. No statistically significant differences between no-DGF and DGF regarding heart rate and surgical complications were found. A notable positive correlation was observed between cold ischemia time and RI (r = 0.65; p < 0.001), RI and MAP (r = 0.47; p = 0.009), operative time and RI (r = 0.86; p < 0.001), length of hospitalization and RI (r = 0.73; p < 0.001).

Conclusion: Results showed that renal resistive index (RI) and Doppler parameters were significantly associated with DGF occurrence. Elevated RI, prolonged cold ischemia time, lower intraoperative mean arterial blood pressure, and higher renal injury markers correlated with DGF.
