A member asked:

Can you tell me what do ultrasound machines do?

Dr. Steven Chmielewski answered

Specializes in Diagnostic Radiology

Ultrasound (U/S): Works similarly to sonar. Sound wave are sent through tissues and the changes in their waveforms are recorded by the transducer. Because sound travels at different speeds through different tissues (or not at all) we can recreate images of structures by measuring the changes in the return echo from the initial sound wave.

Dr Fowler and another doctor agreed

I have a rather large kidney stone and it definitely wont pass. Also I have no insurance. Are there any alternatives to lithotripsy to break up the stone? Possibly a shockwave pain therapy ultrasound machine?
