    Abstract:
    PURPOSE: Peri-aneurysmal fibrosis complicating inflammatory aneurysm of the abdominal aorta may involve the ureters, causing urological complications. We assessed patient anatomical and clinical outcomes after conservative ureteral management. MATERIALS AND METHODS: From the operative records of 1,271 consecutive patients who underwent surgical repair of abdominal aortic aneurysms from 1980 to 1999 we identified 77 (6%) who had inflammatory aneurysms, which were complicated in 19 (24.6%) by dense peri-aneurysmal and ureteral fibrosis. Of these 19 patients 15 (78.9%) had coexisting monolateral hydronephrosis, 3 (15.7%) had bilateral hydronephrosis and 1 (5.2%) had renal atrophy. In 14 cases (73.6%) the fibrotic reaction severely impaired renal function. Only 1 patient underwent an emergency operation, while the others underwent elective repair. Only 2 patients (10.5%) underwent a specific urological procedure, including bilateral nephrostomy in 1 and ureterolysis plus ureterolithotomy in 1. Most ureteral complications were treated conservatively by aneurysmectomy only. RESULTS: Immediate postoperative mortality was 7% (1 of 14 cases). Median followup was 48 months. In 1 of the 13 cases (7.7%) a ureteral stent was placed during followup. After aneurysmectomy in 9 of the 12 patients (75%) with renal dysfunction periaortic fibrosis disappeared or decreased as well as associated hydronephrosis. In 11 of the remaining 12 patients (91%) of the 14 with renal failure preoperatively kidney function returned to normal or improved. In the 2 patients who underwent a specific urological procedure renal function improved but did not return to normal. CONCLUSIONS: Inflammatory abdominal aortic aneurysms involving the ureters and compressing the urinary structures respond well to aneurysmal resection only without a urological procedure.
