"Hemodialysis is one of the most important and effective dialysis therapies for chronic renal failure. Despite hemodialysis Function is Blood detoxification but it has Complication such as fatigue, anemia, heart problems and hearing disorders that are created on the basis of these Complications, so patients should be followed in dialysis duration. In this study, patients were followed up for the high-frequency hearing losses are discussed. This a cohort study, Patients with chronic renal failure were randomly selected and examined prior to the start of dialysis. Patient with normal Examination were has been Test with Tympanometry and acoustic reflex testing SDT, SRT, PTA. 40 patients undergoing dialysis, 22 patients [57.1%] males and 18 [42.9%] female and the mean age of study participants was 15.4 ± 46.9 years. SDS test the relationship between the left and right were statistically significant. [P <0.001] between the right and left SRT test did not show any significant difference .In PTA testes in the High Frequency The mean follow-up of three frequencies 10000 and 12500, with p = 0.0001 and p = 0.005 statistically significant relationship was found., And the 16000 frequency with p = 0.212 There was no significant relationship. Frequencies 10000 and 12500 are more susceptible to hearing loss or Ototoxicity. Recommended it's better to follow hemodialysis patient use Ultra high frequencies."
