I think i can help your wife. I not only have had stones but I was the very first Extracorporeal Shockwave lithtotripsy Program Coordinator in the Veterans Administration Medical Centers in the US.
I really feel for anybody going through kidney stones! Labor pains were easier! If you or your wife care to contact me you can email me at
sunnymaryann@bellsouth.net. I will be happy to answer any questions you may have. I am probably more alert to emails than postings on this forum since i check my mail every few hours.
