BUT I AM NOT SATSFIED WITH THESE AS I KNOW SEVERAL MESSED UPS. PLEASE ADVICE ME
[|AI|]  From the information provided I understand your friend has had stents placed in the ureters. He will need further tests to find out the cause including CT/MRI of abdomen, and he might need ureteroscopy which is camera inspection of the ureters. Unless we look at your old records and scans done previously we cannot comment on it father. There are multiple causes for the blockage including stones, blockage by birth called PUB obstruction, growth within your abdomen or growth within the ureters, scar from previous operations, etc.
