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.
