Doppler ultrasound evaluates transplant kidney function

Tuesday, November 28 | 1:50 p.m.-2:00 p.m. | T6-SSGU04-3 | Room N227B

Attendees will learn how Doppler ultrasound can image the renal function of transplanted kidneys in this session.

Eujin Lee, MD, from Soonchunhyang University Hospital in South Korea will show how drawing a region of interest along the border of a transplanted kidney can measure the vascular index in superb microvascular imaging, is reproducible, and correlates well with estimated glomerular filtration rate (eGFR).

Previous research highlights the utility of Doppler ultrasound for measuring the vascular index of lesions in the neck and breast areas. Lee and colleagues wanted to explore the reproducibility and value of the vascular index of superb microvascular imaging in Doppler ultrasound in evaluating the renal function in transplanted kidneys.

The researchers found statistically significant differences in the vascular index of the transplanted kidney according to chronic kidney disease groups based on eGFR (p < 0.001 for all) and disease risk groups based on eGFR and albuminuria. The team also reported that the interobserver agreement of three different vascular index measurements was excellent and that urine albumin-creatine ratio was independently associated with eGFR.

“The vascular index of superb microcvascular index in Doppler ultrasound provides a noninvasive, quantitative, and reproducible assessment of renal function in the transplanted kidney,” the team wrote in its abstract.

To find out what else the researchers found, attend this session.
