Uretero-Arterial Fistula - Not So Rare?

Area of Science:

• Urology
• Vascular Surgery
• Oncology

Background:

• Uretero-arterial fistulas (UAFs) are rare, with only 139 cases reported by 2009.
• The incidence of UAFs appears to be increasing.
• Aging populations, improved cancer survival, and multimodal pelvic cancer treatments are contributing factors.

Observation:

• Literature review on UAFs, risk factors, pathophysiology, and treatment options.
• Presentation of a case involving a fistulous communication between the internal iliac artery and ureter.
• Identification of a potential novel risk factor for UAFs.

Findings:

• UAFs are more common than previously thought.
• Multimodal pelvic cancer treatments and an aging population are key drivers of increased UAF incidence.
• The internal iliac artery is a common site for UAFs.

Implications:

• Increased awareness and diagnostic vigilance for UAFs are necessary.
• Understanding risk factors and pathophysiology can guide preventative strategies.
• Further research is needed to explore novel risk factors and optimize treatment for UAFs.
