Summary
Asymptomatic hydroureteronephrosis (HUN) occurred in 7% of patients post-aortobifemoral graft surgery. These cases resolved spontaneously, suggesting routine screening is unnecessary for this specific complication.
Area of Science:
- Vascular Surgery
- Urology
- Nephrology
Background:
- Aortobifemoral vascular grafts are used to treat peripheral artery disease.
- Hydroureteronephrosis (HUN) is a potential complication following vascular surgery.
- Understanding the incidence and natural history of HUN post-aortobifemoral grafting is crucial.
Purpose of the Study:
- To determine the frequency and natural history of hydroureteronephrosis (HUN) after aortobifemoral vascular graft placement.
- To assess the clinical significance of asymptomatic HUN in this patient population.
Main Methods:
- Prospective study of 30 patients undergoing aortobifemoral graft surgery.
- Evaluation included pre/postoperative kidney function tests, intravenous pyelograms, and late ultrasonography.
- A total of 57 ureters were assessed for HUN.
Main Results:
- Four asymptomatic cases of early HUN were detected (7% incidence).
- All identified HUN cases spontaneously resolved within 30 days.
- No symptomatic early or late HUN was observed in the study cohort.
Conclusions:
- Asymptomatic early HUN is a frequent finding after aortobifemoral grafting but is typically benign.
- The spontaneous resolution of these cases indicates that systematic screening for asymptomatic HUN may not be warranted.
- These findings contrast with symptomatic HUN cases reported in the literature, which require further investigation.
