I have had lithotripsy several times and two different ways. About 10 years ago I had my 3rd lithotripsy done at a Lithotriptic Center. The process there was to give me an epidural and happy drugs, lower me into a tank of water and hit my back with shock waves. For a few days I did feel like someone had punched me in the back.
In the past few years I've had another type of lithotripsy done (twice, I think). This time it was on a lithotripsy machine. I was given general anesthesia, and I felt absolutely fine afterwards. No soreness or anything!
With both types my doctor also inserted a stent. This was to make it easier for the remnants of the stones to pass more easily. I agree that the stent is no picnic. My doctor prescribed pain killers and something to prevent spasms because your body does not like having a foreign object inside it. The body will try to reject it. Take the drugs!!!
Each time the stent was removed, I felt instantly better ... except the last time. I went home and felt fine at first. Then I began having spasms. I laid in bed curled up in a ball. I pain felt very much like the stone did when it was first causing me pain ... but not nearly as intense. My husband was at work and the kids were at school. My husband called my doctor for me, and they told me that this does sometimes happen (spasms). They had me come back to the office and gave me a shot of Toradol. It's not a narcotic but relaxes everything. They also gave me a prescription for Toradol that I took for a few days afterward.
Bottom line, this procedure can be uncomfortable for a few days (soreness) and the stent is annoying, to say the least. But the whole thing is relatively painless, and the stent will be gone in about a week.
I noticed Amanda say to "have the doctor make sure they are small enough stones that he will easily pass them once broken." The doctor is going to do everything he/she can to make sure the stones are small enough. The problem with larger stones (I had one that was the size of my thumbnail. That's huge!) is that as they are broken apart, they break into small pieces like sand and it becomes more and more difficult for the doctor to see. This is why the doctor will take followup x-rays. As the teeny, tiny pieces pass it will become easier to see whether or not larger pieces remained. Unfortunately, you just have to wait and see. I once had to have lithotripsy a year later to get that one last piece that was too big to pass. Not my first choice, but what can you do.
It's not so bad, really. And he'll be so glad to have it over and done with.
