Perianeurysmal fibrosis and ureteric obstruction: case report and review of literature.

A case of ureteric obstruction due to perianeurysmal fibrosis is reported and the literature reviewed. Reports of 56 previous cases showed striking male predominance, the presenting symptoms being abdominal pain, flank pain and back pain with radiation to the groin or leg. Anuria occurred in 14.2%, and an abdominal mass was palpable in 45%. The pathogenesis and pathology of perianeurysmal fibrosis is discussed. The treatment of choice is bilateral ureterolysis and resection of the aneurysm, but in elderly, sick or uremic patients more limited procedures may be indicated.
