replies: text: 100 shockwaves of WHAT frequency? 1 Hertz? 10 Hertz? 1 gigahertz? There is frequency of the PULSE and there is the frequency of event (the shockwave). From two documents, the physics seems to be a bit complex for Wikipedia. First, for current model machines, a 1-5 MHZ pulse is sent. Immediately after, a 100 khz - 1 MHZ pulse is sent, which causes a cavitation cloud around the stone to resonate. One power setting (or possibly, cumulative effects of each pulse) will shatter the stone. From http://www.jsme.or.jp/English/news06.pdf and http://www.eng.bu.edu/~robinc/pubs/ClevelandMcAteerSTEU06.pdf , to reveal my sources of a 3 second Google search. READING the documents took a bit longer, but gave me some REALLY cool ideas on multi-focal applications of certain lower frequencies.  :)   Wzrd1 (talk) 05:02, 19 October 2011 (UTC)

text: There is not a single frequency, but a peak on the frequency distribution where the energy is greatest.  To see this, look at the Fourier transform of an average pulse.  For an HM3 in usual operation, the transform peaks around 300khz, and has fallen by 15db at 1mhz. The squarer the pulse, the flatter the distribution, the closer the pulse resembles half a sine wave, the spikier the distribution. Rule of thumb, take the most energetic frequency as f=1/t where t is the pulse duration.  — Preceding unsigned comment added by 75.130.24.169 (talk) 17:18, 11 February 2015 (UTC)

message: The article on gallstones state that it is a common misconception that ESWL is used to remove gallstones, whereas the very first sentence in this article state ESWL is indeed used to this purpose. Anyone knows the truth?
I am by no means a doctor, but I personally have had both gallstones and kidney stones and as a result of the gallstones I had my gall bladder removed. No one ever even mentioned this procedure. I had never even heard of it until my urologist instructed me to have it done next Wednesday for my kidney stones. I will write back and let you all know how it feels.75.67.60.74 11:46, 2 June 2007 (UTC)
thread_title:  Misconception? 

message: Under "How it works", the patient is said to be sedated or anaesthetised, but later in that paragraph it says that the patient might be sedated in order to suppress pain. These statements seem to contradict each other: the first states that the patient is always sedated or anaesthetised while the second implies that this isn't necessarily so. Could someone clear up this anomaly please? I am not a doctor. :)  — Preceding unsigned comment added by Schmeditator (talk • contribs) 11:44, 17 January 2012 (UTC)
