Abstract: Introduction: This study aimed to investigate the relationship between left ventricular ejection fraction (LVEF) measured on preoperative transthoracic echocardiography (TTE) and peak systolic velocity (PSH) and resistance index (DI) calculated on postoperative renal Doppler ultrasonography. Methods: The study retrospectively included 68 renal transplant patients. TTE measurements were taken for all patients, and LVEF was recorded. Renal Doppler ultrasonography recorded PSH and DI. Patients were divided into two groups based on LVEF below 55% (group 1, n=24) and above (group 2, n=44). Results: Of the patients participating in our study, 21 (30.8%) were female and 47 (69.2%) were male. The mean age of the patients in the study was 53.2±9.27 years. Urea was significantly lower in patients with LVEF values above 55% (85.9±31.5 vs. 103.3±35.2; p=0.02). On the other hand, PSV and RI were significantly lower in the group with LVEF values above 55% (188.2±33.1 vs. 238.7±40.2; p=0.02; 0.64±0.15 vs. 0.78±0.19; p=0.04, respectively). A negative correlation was also found between LVEF values and PSV and RI (r= -0.731, p=0.007; r= -0.602, p=0.01, respectively). Conclusion: In this study, renal transplant patients with echocardiographic LVEF greater than 55% had significantly lower RI and PSV determined by renal Doppler ultrasonography.
