Hearing Loss in Chronic Renal Failure Patient Undergoing Hemodialysis

End stage renal failure patients, face to multiple
complications. One of them is the involvement of auditory
system. There are several proposed mechanisms for
occurrence of hearing loss in these patients. There is no
study performed in Iran for determining the status of
hearing loss and results of audiometric tests in chronic
renal failure patients. To assess prevalence, type and
accompanying factors of auditory complications in end
stage renal disease patients. Seventy chronic renal failure
patients underwent clinical examination and audiometric
tests. Their medical records reviewed to find out any
contributing factor with auditory complications. There was
higher prevalence of sensory neural hearing loss in CRF
patients. The hearing loss was more obvious in higher
frequencies. Its prevalence and severity increased with
chronicity of renal failure and hemodialysis. There was not
any difference regarding the sex. The hearing loss did not
disturbed speech discrimination score and acoustic reflex.
Sensory–neural hearing loss is common among CRF
patients and deserves more attention than is paid by current
approaches
