Have Urology Questions? Ask a Urologist Online.
This is Dr. David
a small kidney stone can do this
or a blockage in the bladder can cause one ureter to dilate and become larger than the other.
how old are you?
sometimes a mass in the bladder can cause one ureter to be larger than the other
you need to see a urologist to get a cystoscopy to look inside of the bladder and check for masses.
do you have any blood in your urine?
do you have your full CT scan report? I would be happy to review that with you.
