Is This Correlation Widely Known And Should I Look Into Getting The Renal Cyst Removed To Help Lower My RBC Values To A Normal Level?

Question : Patient ProfileGender: MaleAge: 35Visited a Doctor: YesMedications Tried: N/A
I have had elevated values of hematocrit, hemoglobin and rbcs for the last 5 years or so. My hematocrit is usually around 51 or 52%. I saw a hematologist who ran multiple tests: JAK2 mutation, JAK2 exon 12 mutation, CALC mutation and EPO test, all of which came back normal and negative for polycythemia vera.

I have a history of kidney stones when I was younger (likely from excessive protein during my high school sport days) so I get renal sonograms from time to time. I was born with a pelvic left kidney and a malrotated right kidney but they are essentially normal with no abnormalities.

In 2017, my renal sonogram noted "Newly seen 3.3cm cyst arising from the lower pole of the right kidney." The following year, the sonogram notes "2.8cm cyst not significantly changed". I saw a nephrologist and they said simple renal cysts are normal and since it didn't grow, it's not an issue at all.



However, the nephrologist didn't know about my elevated red blood cell values and I just came across this article: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC0000 , which states: "Patients with simple renal cysts have high values of red blood cells, hematocrit, and hemoglobin. Treatment decreases blood pressure in patients with hypertension. Complications after treatment are rare and mild."

Is this correlation widely known and should I look into getting the renal cyst removed to help lower my RBC values to a normal level?

Thank you, Dr. Madhyastha.

I had my EPO tested twice and it was 7mU/mL (ref range: 3 - 26mU/mL) and then 10mU/mL the 2nd time so it seems to be in the normal range. Also, my JAK2 mutation was negative as well as the JAK2 exon 12 variant of the mutation was negative as well so my doctor thinks it's highly unlikely it's Polycythemia Vera. I saw a pulmonologist and they did a sleep study as well as normal breathing tests and everything came back "normal". I don't smoke or live at high altitude either.
Could this just be simple dehydration?

Thank you. My haemoglobin ranges between 16.6 - 17.9 grams per deciliter, which is slightly above the normal range. I have ranged between those two numbers for the last 5 years or so.
