The Effect of Hemodialysis on Sensorineural Hearing Loss in Chronic Renal Failure Patients

Sensorineural hearing loss (SNHL) can occur in patients with chronic renal failure (CRF) who receive hemodialysis (HD). SNHL is caused by hemodialysis occured in any frequency. The factors affect the disease include, among others, age, hypertension, and diabetes mellitus (DM). The effect of hemodialysis onSNHL occurrence in patients with CRF was analyzed in this study. It was a cohort study on 52 patients with CRF who met the inclusion criteria. The sample consists of two groups, 26 patients with CRF who received hemodialysis and 26 patients with CRF who did not received hemodialysis. Timpanoaudiometry was performed on HD group (patient with HD) before the first HD and after the third HD. Timpanoaudiometry was performed on HD group (patient without HD) at the same time with the first group. The data on age, hypertension, and DM were obtained from medical records. The results were analyzed with Chi-Square test. It was found that 30.7% SNHL patients were in the HD group consisting of 26.9% mild degree patients and 3.8% moderate degree patients. Mean of hearing threshold decrease was 8.13 5.30. There was no patient with SNHL in the non-HD group. Analysis with Chi-Square test showed that hemodialysis affects SNHL occurrence (p=0.004). Age (p=0.084), hypertension (p=0.215), and DM (p=0.683) do not affect SNHL occurrence. It is concluded that hemodialysis affects SNHL occurrence whileage, hypertension, and DM do not.
