hi....
lithotrepsy is a good non invasive procedure for small stones....
but it has a shortcoming of being small particles left some time,which then act as a nidus for recurrant stone....
now depends on the size of stone...if its size is less than 7mm,then it can pass out by itself in urine....if medium size go for
lithotripsy,if very large then open surgery....
wish you good health..
