Ureteric Obstruction Due to Peri-Aneurysmal Fibrosis

Abstract

CULP AND BERNATZ (1961) found that 10 per cent. of 400 cases of aneurysm of the abdominal aorta had symptoms suggestive of a genito-urinary disorder. They pointed out that although the ureters are often displaced by the aneurysm, this displacement rarely results in obstruction even on the surface of huge aneurysms, unless the ureter is caught in peri-aneurysmal fibrosis. Careful review of the literature has revealed only 6 such cases which were treated surgically.A further case is described here in which ureteral obstruction due to peri-aneurysmal fibrosis was relieved surgically, and this condition is considered in the light of previously reported cases.

Uretero-Iliac Artery Fistula: A Diagnostic and Therapeutic Challenge

“…The ureter can become fixed and obstructed by the surrounding inflammatory process. Chronic pulsations to the fibrosed, less compliant ureter can cause necrosis and eventually formation of a fistula [3]. Fistula formation could further be hastened by having a fixed ureteral stent in place [1].…”

“…Ureteroscopy under high pressure gradient has also been reported to confirm the site of hematuria, with a diagnostic accuracy of 64% [3]. …”
