=============================================
Dear Chris,
Your concerns are quite legitimate. From your history you are a chronic stone former. This is of course a very difficult problem to live with, as I am sure you are well aware of.
From your descriptions I suspect that you have blood in your urine causing the discoloration. This could be due to the irritation from the stones or infection or both. You must be evaluated and treated accordingly before too long.
There are different kinds of lithotripters, but the most effective is the original one(HM3) made by Dornier from Germany , which uses a bathtub for the patient to be immersed in. The more modern versions have their own advantages as well, such as being less traumatic, or not requiring any anesthesia , or need for a bathtub. But the stone crushing capacity of the HM3 is superior.
Lithotripsy, even though an effective method , is not the ultimate answer to your dilemma. You need to have a full work-up for your underlying metabolic problem that causes you to form as many stones as you have. This would include a 24hr. urine sample and some blood tests, as well as biochemical analysis of your most recent stones. The results may help to tailor a combination medical/ diet treatment regimen to help decrease, or hopefully stop, your stone formation.
You need to discuss this with your urologist(s), and come up with a plan. If you will not get any results, you may be well advised to find a urologist who specializes in stone disease and treatment.
The best of luck to you.
