[The evaluation of some parameters of hearing in patients treated by long-term hemodialysis].

Audiologic examinations were performed in 10 patients with chronic renal failure treated by long hemodialysis. Hearing loss was found in 4 ears (20%). We didn't find correlation between the hearing loss and the levels of sodium, potassium or uremic toxin. After using tympanometry and audiological tests we conclude that hemodialysis "per se" does no harm to the function of middle ear and cochlea.
