Abdominal aortic aneurysm: Perianeurysmal fibrosis and ureteric obstruction and deviation.

Seven cases of ureteric obstruction and one case with bilateral medial ureteric deviation complicating inflammatory aneurysm of the aorta are reported. The value of routine preoperative pyelography in all patients with abdominal aortic aneurysm is emphasized. Diagnostic difficulties that may arise when these conditions coexist are discussed. Our experience suggests that these patients are best treated by both aneurysmectomy and ureterolysis and that long-term follow-up is advisable.
