Is It Possible For The Shock Waves To Hit The Wrong Area During Lithotripsy?

61 yo Female-had lipotripsy done yesterday morning. (6 yrs ago had same done) Concerned that where they "hit" me is not the correct place.(?) Bruise this time is about 4" down from my left shoulder blade. This is not where my initial pain was(on the left side below my waist. Still have the same stone pain as first felt before the procedure. (3 large stones were to have been in the Left Kidney & had not started down the tube) This just does't seem right????? What's up????

Hi
It is common to have skin irritation symptoms following lithotripsy. The shock waves have to pass through the skin and get focussed on the stone- so the maximum concentration of the shock wave is on the stone but some falls on the skin as well.
This may not be the same achine you have had 6 years ago and power and efficiency of machine can change in a different machine -hence the bruise may not have happened previously. If bruise is large seek medical help and get a blood test to check your coagulation profile done.
Sometimes depending on hardness of the stone, one session may not be enough to break the stone and hence pain relief may not be immediate.
I find this answer helpful
