My mother recently had a cat scan and ultrasound of the stomach and it was found that she has a cyst in her right kidney measuring 2.0 centimeters.  No gall stones or kidney stones were seen although my mother had been having discomfort with urination for at least a week.  Now I notice that she has a hot stomach from time to time.  What is causing this hot stomach?  Should she be further tested?
Hi, welcome to Chat Doctor. Cyst in the kidney is mostly a benign finding and most of the time accidentally detected. It requires evaluation with CT scan with contrast. This will tell us the nature and stage of the cyst and further plan of action. Do basic urine report, S. Creatinine and then consult Nephrologist before doing CT scan. Hot stomach require gastroenterologists consultation with sometime UGI copy required. Feel free to communicate further with your reports. Besy wishes. TC. Chat Doctor.
