My understanding was her stones were caused by dehydration. Your poor wife!What happened was the emergency visits for the kidney stones. That got it kicked to a urologist that agreed about the stones likely being caused by the tumor. We had to go to an Endocrine Surgeon to get the diagnosis and finally a contrast scan to find the tumor. We then went to UCSF for the surgery because they are one of the top three in the US that does the surgery.
