Thanks so much @colleenyoung 😊 You posted the perfect link for me to read the previous discussions on renal complex cysts. Thank you! This is exactly the information I was looking for.
My doctor told me "not to worry" and we will retest with ultrasound in 6 months to make sure there is "interval stability". I assume that means to make sure it's not changing or growing. I am not sure if a Cat Scan or MRI might help to give additional details regarding the cyst or if it's unnecessary to have more details at this time.
He also mentioned that the cyst may be a result of the one year protocol kidney biopsy that I just had in August. I found that comment to be interesting since the frequency of all the protocol biopsies concerned me before this new cyst diagnosis. I don't like the idea of poking holes in my new wonderful kidney on a regular basis, but I want to follow the medical protocols too. It's a dilemma.
