[Application of extended high frequency audiometry in the patients with chronic renal failure treated by hemodialysis].
OBJECTIVE
To explore the features of hearing changes in patients with renal insufficiency treated with hemodialysis.


METHODS
Forty-nine patients with chronic renal failure ongoing hemodialysis and 66 normal controllers were enrolled in this study.


RESULTS
The changes of the averaged hearing thresholds of high frequency for hemodialysis subgroup were similar to those of the control group, but the impairment of the hearing was more severe. Compared with the control group, there was significant statistically differences in every age segments.


CONCLUSIONS
The hearing impairment in patients with chronic renal failure treated with hemodialysis is characteristic by decreased in high frequency portion.
