High-frequency hearing loss in chronic kidney disease: a frequency-specific analysis across renal function stages

< 0.01) These findings provide novel frequency-specific evidence that compared with controls, patients with non HD CKD already demonstrate poorer high-frequency thresholds, suggesting possible early involvement even prior to the initiation of HD. The results underscore the importance of routine high-frequency audiological screening for CKD patients, as early detection may help to prevent or mitigate further deterioration in auditory function. This study is among the first to demonstrate frequency-specific differences in hearing loss across distinct renal function groups.
