Summary

The Econolith 2000 lithotriptor, used for kidney stones, generates noise levels up to 96 decibels. However, with protective ear use, it does not cause hearing damage in patients.

Area of Science:

  • Nephrology
  • Audiology
  • Biomedical Engineering

Context:

  • Urolithiasis treatment relies on lithotripsy, which generates significant noise.
  • Occupational hearing damage is a concern above 85 decibels.
  • The Econolith 2000 is an electrohydraulic lithotriptor requiring safety assessment.

Purpose:

  • To assess the potential for hearing damage from the Econolith 2000 lithotriptor.
  • To measure sound intensity during lithotripsy procedures.
  • To evaluate the effectiveness of hearing protection.

Summary:

  • Audiometry was performed on 10 patients before and 24 hours after lithotripsy.
  • Sound intensity measured 96 dB in the operating room and 70 dB outside.
  • No hearing damage was observed in patients using protective ear devices.
