I was diagnosed two years ago and had a lap to remove endo. It has now come back and I am waiting to see my consultant next month. My GP decided to do some routine blood tests while I wait and my kidney function showed up as being dodgy so he re-did the test and the same again. I've now got to go for a kidney and renal tract scan at the hospital. Could this be endo related or just something else? Has anyone else had the smae?
