Hydronephrosis complicating aortic reconstruction.
The British Journal of Surgery
|May 1, 1975
Summary
Hydronephrosis can complicate aortic reconstruction surgery. This study found a 10% incidence in patients undergoing vascular reconstruction near the ureter, with some cases resolving post-operation.
Area of Science:
- Urology
- Vascular Surgery
- Radiology
Background:
- Hydronephrosis is a potential complication following aortic reconstruction.
- Synthetic materials used in aortic repair can pose a risk to adjacent ureters.
Purpose of the Study:
- To investigate the incidence and characteristics of hydronephrosis after aortic reconstruction involving synthetic materials near the ureter.
- To assess the long-term outcomes of ureteral complications in these patients.
Main Methods:
- A consecutive series of twenty patients undergoing aortic reconstruction for occlusive vascular disease were studied.
- Intravenous pyelography was used to evaluate for hydronephrosis in the postoperative period and at long-term follow-up (1 year or more).
Main Results:
- The incidence of hydronephrosis was 10% of patients and 5-7% of at-risk ureters.
- Dilatation was typically observed in the immediate postoperative period.
- Approximately 50% of immediate postoperative dilatations resolved within one year.
Conclusions:
- Aortic reconstruction requiring synthetic grafts near the ureter carries a risk of hydronephrosis.
- While some hydronephrosis may resolve spontaneously, vigilant monitoring is warranted.
- Further research may explore preventative strategies for ureteral complications during aortic surgery.
