[Vestibular function in calcium and phosphate metabolism disorders in chronic renal failure]

45 patients with chronic renal failure (25 dialysed and 20 undialysed) were examined for function of vestibular organ and 35 patients with chronic renal failure treated by diet and drugs were examined for hearing acuity by pure tone audiometry and above-threshold audiometry. All patients serum sample's were examined for calcium, inorganic phosphates and uric acid. The examination revealed the damage of vestibular organ in 84.4 per cent of patients and statistically significant increase of parathormone serum concentration in patients with central type of damage. The hearing loss was found in 51 per cent of patients. The hearing loss in most number of cases was symmetrical and it was mainly the extracochlear auditory damage. The role of disturbances in calcium and phosphates metabolism in the pathogenesis of hearing loss seems to be unsure.
