Hi,I just found out that I have a fairly large peripelvic kidney cyst causing distotion of the pelvocaliiceal system.  What kind of doctor treats this.  I have been experiencing considerable pain.  I was told this after having a CT scan by a surgeon and he referred me to a urologist.
Hello, Large perihelia renal cyst which is causing pain or symptoms will need either excision or Chat Doctor.  A urologist. After studying the CT report and depending on the size and extent of the cyst, the surgeon will take a call on the procedure required. As you haven't mentioned the detail CT report here, I am having limitation to comment anything. But a urologist is the person you should be consulting with the report of CT scan. Kindly revert if you have any more query. Thank you
