Obstructive nephropathy as a result of retroperitoneal fibrosis: a review of its pathogenesis and associations

Abstract

Retroperitoneal fibrosis is a rare disease, typically with an insidious clinical course. It is thought that this disease process is perhaps an exaggerated reaction to an inciting inflammatory event. In this study, a case of retroperitoneal fibrosis is reported, in which the patient presented with typical symptoms of retroperitoneal fibrosis, along with some atypical vasculitic symptomatology. Retroperitoneal fibrosis is a disease process with an unknown etiology, which has been observed to be associated with a number of different possible inciting factors. Two factors that have been documented in the literature as being associated with retroperitoneal fibrosis include the use of beta-blocking agents, and connective tissue disease processes such as systemic lupus erythematosus. The patient discussed was using beta-blocker medication and also had signs and symptoms suggestive of a lupus syndrome. There are no reported cases of the combined association of beta-blocker usage, lupus, and retroperitoneal fibrosis.
