Ureteral obstruction as a complication in aorto-iliac reconstructive surgery
Scandinavian Journal of Urology and Nephrology
|January 1, 1983
Summary
Ureteral obstruction can occur after aorto-iliac reconstruction with grafts. This complication, caused by fibrosis or mechanical compression, often presents with diffuse symptoms but has a good prognosis after treatment.
Area of Science:
- Vascular Surgery
- Urology
Background:
- Aorto-iliac reconstruction using bifurcation aortic grafts is a common procedure for treating aortic aneurysms and occlusive disease.
- Ureteral obstruction is a rare but serious complication following this type of surgery.
Observation:
- This study describes two cases of ureteral obstruction secondary to aorto-iliac reconstruction with bifurcation aortic grafts.
- A review of 28 additional cases from the literature was performed to analyze the etiology and outcomes.
Findings:
- Two primary etiological factors were identified: localized fibrosis around the graft and mechanical compression of the ureter, often due to its posterior placement relative to the graft.
- Symptoms are frequently diffuse and non-specific, potentially delaying diagnosis.
Implications:
- Despite often diffuse symptoms, prompt operative intervention leads to a favorable prognosis for patients experiencing ureteral obstruction post-aorto-iliac reconstruction.
- The true incidence of this complication remains unknown, highlighting the need for increased awareness among surgeons.
