Abstract: | The objective of this study was to evaluate the management and course of obstructive uropathy secondary to inflammatory aneurysms. From January 1981 to December 2000 a total of 52 patients underwent surgical intervention for inflammatory aneurysms of the abdominal aorta. Eleven of these cases (21%) had obstructive uropathy, which was bilateral in five cases. Preoperative drainage of the urinary tract was done in five ureters in three patients with four double J catheters and one percutaneous nephrostomy; surgical ureterolysis was also carried out in one case. Endoaneurysmorraphy and placement of an aortic graft were performed in all 11 patients. Operative mortality was zero. There was no recurrence of hydronephrosis in seven patients during a mean follow-up of 55 months. Three patients were lost to follow-up and one died. When compared with 41 inflammatory aneurysms in which hydronephrosis did not develop, there were statistically significant differences with respect to lumbar pain and renal insufficiency. The ureter is a structure adjacent to the aorta that is trapped by fibrosis in 21% of patients with inflammatory abdominal aortic aneurysms. The natural tendency of the periaortic fibrosis is to remit following surgery to correct the aneurysm. This results in spontaneous remission of the hydronephrosis, making routine intraoperative manipulation of the ureter unnecessary. |
