Thank you everyone who has responded with helpful suggestions. We were able to get the Dr. on her case to finally order tests to see if she had anything wrong with her kidneys or ureters and those came back negative. While she was hospitalized she was on antibiotics, so whatever was going on then seems to have been taken care of for the time being. We are doing the research on the ICC and we will ask her regular Dr. to test for that if anything shows up again. Thanks again everyone.
