What are the side effects of radiation used in lithotripsy?

Hello doctor,

I am 24 years old. I had my kidney stone removed a year ago for causing mild hydronephrosis at my right kidney. During the treatment, I was exposed to full of radiation, abdominal CT scan, lithotripsy, fluoroscopy, and another fluoroscopy during stent insertion. I am not sure how the doctor manages the radiation. I did my treatment abroad and it is not really a well-developed country. He might not even care bout it. I studied some about radiation when I was in dental school so I am very scared of the side effects. So if I am to have another case of hydronephrosis, should I just remove the kidney rather than undergoing such radiation which may cause me high risk of future cancer? Because as you can see, I am still so young and I just started my career. What do you suggest? Do the pros outweigh the cons or vice versa? Is there another less risky treatment in terms of radiation? How about invasive treatment? Is the risk higher aside from the slow healing? And I am serious about the removal if indeed it has lower radiation risk, even though I know kidney is very important. Please suggest.
