I was diagnosed with polycystic kidney disease about 25 years ago. I have had regular bloodwork done since then. I have watched my creatinine level which has alway been between .9 and 1.1 until this last fall. I had gone to my eye doctor with glaucoma symptoms, and found out that I had psydotumor cerebri. This is excess spinal colum pressure in my brain pushing my optic nerves into my eye. I was starting to lose vision. He had me do a very complete blood test that showed slightly elevated sugars, 111, and my createnine was 1.3. A month later, it was back to 1.14. When I saw my doctor, he told me that I had 50% kidney function. It was not my normal doctor, I didn't know what to ask. I later found that my filtration rate was low, around 40.
My question is, what is used to determine kidney function. I thought I was doing fine as my creatinine was low.
My older sister had a transplant several years ago, and my sister 2 years younger had her kidneys removed in November and is awaiting a transplant. She told me that her function was 50% a year before. I will see my doctor and review bloodwork I will have taken this week next week. I want to make sure I ask the correct questions.
I still have high pressure in my spinal column. When I have a spinal tap, my blood pressure is easier to control for a week or so after. Is there any relation to high spinal column pressure (35) normal is less than 20, and kidney function.
