Ultrasonic lithotripsy often doesn't always work and can damage your kidneys. When it didn't work for me after two tries, another urologist stepped in, said it could be potentially damaging and took different path.
The procedure that worked for me several times was ureteroscopic laser lithotripsy where a laser is used to blast the stone into pieces that will pass. The downside to that is that it feels like your pissing glass for several days due to the irritation of scope going up and back out your johnson.
