Summary
Chronic dialysis patients often have hearing loss, but most do not experience worsening hearing during treatment. This study followed 20 patients undergoing hemodialysis or peritoneal dialysis for 1-4 years.
Area of Science:
- Nephrology
- Audiology
- Otolaryngology
Background:
- Hearing deficits are common in patients with chronic renal failure.
- The etiology of hearing loss in these patients is multifactorial.
Purpose of the Study:
- To assess the effect of chronic dialysis on hearing acuity.
- To determine if hearing loss progresses in patients undergoing maintenance hemodialysis or peritoneal dialysis.
Main Methods:
- A cohort of 20 patients on chronic maintenance hemodialysis or peritoneal dialysis was studied.
- Hearing examinations were conducted every 6 months over a 1-4 year follow-up period.
Main Results:
- 70% of patients had measurable hearing loss at baseline.
- 75% of patients showed no deterioration in hearing acuity during the follow-up period.
Conclusions:
- Hearing loss is prevalent in chronic renal failure patients.
- Most patients undergoing chronic dialysis do not experience further hearing acuity deterioration.
