Standardized sonographic parameters POV and PVD show association with chronic injury in kidney transplant dysfunction Can an ultrasound scan spot hidden damage in a transplanted kidney?

A retrospective single-center cohort study of 350 kidney transplant biopsies found that standardized sonographic parameters POV and PVD were associated with histopathologic markers of chronic injury, while resistive index showed no association. The findings suggest these non-invasive markers may support biopsy evaluation. However, biopsy remains essential for definitive diagnosis.

When a transplanted kidney starts to fail, doctors need to know why. A new study suggests two specific ultrasound measurements might act as non-invasive clues to chronic damage inside the organ. This could one day help monitor patients, but a biopsy is still the only way to get a definitive answer.
