I discovered on an ultrasound that I have a gallstone and there are also two more symptoms that I do not know what they are: bilateral renal duplicity suggestive of pelvic duplicity. What would this be?
Expert answer:

Duplication means two (duplicate), renal is referring to the kidneys, bilateral is on both sides (right and left) and pelvic is your pelvis a region of the body, it is your lower abdomen.
