<s>[INST] Hi for the past 2 months I've had pain in the left kidney area going down to my bladder, I have gone to my GP and had a ultrasound and a CT scan and upon discoveries my left kidney is smaller then my right I have scarring and calcification in the left kidney and I also have 2 ureters. 1 going from the left kidney to the bladder and 1 going from the left kidney to nothing, this one is also dilated. They have also found a 22mm stone in my gall bladder. My GP has said to me to just leave it and see what happens. Should I be asking for a referral to a urologist? As a child I had several operations for duplex kidneys that was at the age of 2 I'm 29 now and haven't had any previous problems. [/INST] Hi ! It is clear from your history that you are asymptomatic despite the abnormality. If in the near future you develop symptoms of pain during urination, fever with chills then you can consider consultation with an urologist.As per your stone in your gall bladder it is better to get it removed by surgery. </s>
