<s>[INST] Hi i'm 45 years old women , who just had a baby 4 months ago,I have recently pain in the lower left side. Ob clear me and i went to urologist, they perform ultrasound and find 2 tiny cysts but the pain is much lower. I asked my primary doctor to send me to ga doctor  ( i was having Ibs many years ago) but he refuse to do,I need a referrals to go to specialist so basically he is forcing me to do ct scan first ? I did many scans before I don't want to have more radiation what to do?Thanks! [/INST] Hello.When a kidney ultrasound shows cysts or other lesions, a more specific test to know the cause of lesions is CT scan.I understand your fear of radiation, but if your urologist request to make CT scan is because it is necessary for a right diagnosis, and because Ct scan benefits outweigh the risks.I wish you good health. </s>
