Summary

Patients with chronic kidney disease show impaired high-frequency hearing. High-frequency audiometry can detect these hearing changes and monitor disease progression in chronic renal failure patients.

Area of Science:

  • Nephrology
  • Audiology
  • Ototoxic effects of medications

Background:

  • Chronic kidney disease (CKD) affects multiple organ systems.
  • Hearing impairment is a potential complication of CKD.
  • Early detection of hearing changes is crucial for management.

Purpose of the Study:

  • To investigate hearing function in patients with chronic renal failure (CRF).
  • To assess the utility of high-frequency audiometry in detecting hearing changes in CRF.
  • To monitor hearing function over time in CRF patients.

Main Methods:

  • High-frequency audiometry (9-18 kHz pure tones) was conducted.
  • Study included 37 CRF patients on conservative treatment.
  • A control group of 96 patients was included for comparison.

Main Results:

  • Significantly higher high-frequency hearing thresholds were observed in CRF patients compared to controls.
  • A notable deterioration in hearing function was documented after one year of follow-up.
  • High-frequency hearing loss progression was evident in the CRF cohort.

Conclusions:

  • High-frequency audiometry is a sensitive tool for identifying auditory changes in CRF.
  • This method can effectively monitor hearing function in patients with chronic kidney disease.
  • Early detection via high-frequency audiometry aids in managing potential hearing complications in CRF.
