Retroperitoneal Fibrosis

Retroperitoneal fibrosis is the formation of scar or fibrous tissue in the area behind the abdomen, where structures such as the ureters and the great blood vessels are located. That tissue can compress the urinary ducts and make it hard for urine to pass to the bladder.

Possible manifestations: dull pain in the lower back, the flanks, or the abdomen, general malaise, and in some cases changes in kidney function or in the amount of urine.

Why it is worth evaluating: by involving the ureters, it can have repercussions on the kidneys, so detecting it and following up on it in time is important.

Who to see? Retroperitoneal fibrosis is addressed with support from nephrology and urology, which assess both the kidney and the urinary tract. If you have persistent lower back pain with no clear cause, discussing it with one of these specialists makes it possible to study it properly.
