Im sorry to hear about your symptoms. Well lithotripsy generally speaking is a very safe procedure the complications occur very infrequently but there is certainly a risk of them occurring. Usually the risk is less than 1% in most cases. The complications which can occur are the following,
Bleeding around the kidney
Obstruction of the urinary tract by stone fragments
Stone fragments left that may require more lithotripsies
Now whether you should gpo through with the procedure or not, i would recommend that you DO go through with the procedure the reason being that you have multiple stones present in both kidneys, although they are not causing an obstruction in the flow of the urine at the moment, they can at any point which can lead to damage to the kidneys in the long run. Secondly since you are in pain it is imperative that the stones be taken care of so that your pain can be controlled. While it is true that pain usually occurs when the stones move through the urinary system, it can occur without them moving as well. One more thing i would like to point out is that since you have calcium stones, it would be wise to get a parathyroid hormone level done if it hasnt been already to determine what is the cause of the repeated stone formation. In addition looking in RTA type I as a cause would be recommended as well.
But in short i would recommend that you do go ahead with the procedure. The risk is very small as compared to the benefits of the procedure. There are other ways to remove them including surgery and basket removal but those would be implemented if the stones were larger in size and present just below the kidney, it wouldnt be wise to go directly into the kidney via surgery to remove stones this small. Only if theye were larger in size and causing damage to the kidney would surgery be recommended, lithotripsy is the best option, along with alkanization of urine.
