Some 10 years ago[or more] [should be by now at least some 12 years ago] a patient of mine who was offered to undergo kidney -stone therapy by shock waves ["galiem"] showed me articles where the severe side -effects of this therapy were already described [hypertension.]
She always brought me "chidushim" [this was long before the routine internet use of many of us], 
Seemingly she had siyata d’shemaya finding these articles.
It should be logic to imagine that shock waves which ‘break up stones" may also do something to the delicate kidney tissue, but maybe I am to primitive in my thinking.
The specialist to whom she showed the article[s] was quite upset with her…………
[even if the article was published in his owns specialist-journal!!] 
Since then i advised all patients to look for alternatives [and there are many alternatives]
Surgery is surely not the only alternative as suggested in the article.
Now -so many years later the article below shows up ,which i think would be good to forward to friends. 

Study: Kidney stone treatment boosts diabetes, hypertension risk

Patients who undergo shock wave therapy that breaks up kidney stones, called lithotripsy, are nearly four times more likely to develop diabetes and face a nearly 50 percent higher risk of high blood pressure over the following decades than those getting alternative treatment, according to Mayo Clinic researchers. 

However, that has not changed the use of lithotripsy at the Mayo Clinic, said study author Dr. Amy Krambeck, a urology resident. 


"Most of our patients have been receptive to shock wave therapy," she said, even after being told about the potential long-term risks, preferring it to alternative treatments such as surgery. 

The report appears in the April issue of the Journal of Urology.
