<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am 50 years old. ultra sonography shows a big cyst occur right kidney . what can I do now?  <response>: Hello;welcome to Chat Doctor The cyst in the ultrasound needs to be differentiated to see if it is benign or hemorrhagic cyst ;also whether you have pain or now is important. Please consult a Urologist and get examined. He will prescribe the needed medicines and if it is a simple cyst it may reduce in size or resolve completely in 2-3 weeks but if it does not then the Urologist will tell you regarding further management. Thanks
