January of 2002 I had may kidney stones removed via soundwave or litrotipsy. And this coming August 27 2007 I'am due fo a gallbladder operation(open suregry). I dont get it why stones are appearing on my body. I dont eat to much fat as others and I used to be very active til my collegedays unlike others who were never been into sports or competitions. Im 28 years old now. Is there something wrong with my body? Until when will stones appear in my body? what can I do to prevent them? Im sick in tired of going in and out of the hospital (physically and emotionally) and it is financially draining to our family. Hope you can enlighten me. Thanks By the way What will expect after the operation?what will i do to prepare for the surgery?
