The sedimentation rate may be elevated. An abdominal CT scan may reveal the retroperitoneal mass. An IVP may indicate obstruction and deviation of the ureters, usually toward the midline. The treatment of symptoms associated with obstructive uropathy may be required. Stents or drains placed in the ureter or in the renal pelvis may provide short-term relief of the symptoms until the mass is removed.
Surgical removal is the fibrosis.
Kidney damage may be temporary or permanent. Call your health care provider if symptoms of retroperitoneal fibrosis develop, including decreased urine volume .
