title: Audiological findings in patients submitted to kidney transplant.
abstract: OBJECTIVE
  To investigate the auditory behavior of patients with chronic renal failure (CRF) undergoing kidney transplantation.
  
  
  METHODS
  Thirty patients were evaluated, 10 (33.33%) females and 20 (66.67%) males, aging from 13 to 26 years (average, 16.97 years; standard deviation, 3.60 years). Patients underwent the following procedures: anamnesis, otolaryngological examination, audiological evaluation (pure tone and high frequency), acoustic impedance measurements and central auditory processing evaluation. A control group was used to compare the high-frequency audiometry results.
  
  
  RESULTS
  The following observations were made: absence of auditory complaints at the time of anamnesis; pure-tone audiometry was predominantly normal; patients presented lower hearing levels at the high-frequency audiometry, when compared to the control group, and as for the acoustic impedance measurements, curves of the type A were predominant; there was a change of the central auditory processing for 14 patients (46.67%) in the Staggered Spondaic Word Test (SSW); there was a significant difference between the age variable and the result of the pure-tone audiometry, that is, hearing sensitivity in thresholds from 250Hz to 8,000Hz decreased with advancing age; and the relation between the type of donor and the SSW test result was significant. Rates were higher when the patients had been transplanted from deceased donors compared to living donors.
  
  
  CONCLUSIONS
  There were no changes in conventional audiological and high-frequency evaluation, or in the central auditory processing. Professionals involved in the care of kidney transplantation recipients must be better informed about the care, prevention, and early identification of auditory disorders.
