Selective angioembolization as a management strategy for angiomyolipoma causing urinary tract obstruction

Area of Science:

• Urology
• Interventional Radiology

Background:

• Angiomyolipoma (AML) is a common benign renal tumor, often asymptomatic.
• Rarely, AML can cause urinary tract obstruction and renal colic.
• Surgical removal is the traditional treatment for obstructing AML.

Observation:

• A patient presented with renal colic due to an obstructing AML.
• Selective angioembolization was considered as a treatment option.
• This approach had not been previously documented for obstructing AML.

Findings:

• The obstructing AML was treated with selective angioembolization.
• The procedure resulted in the resolution of urinary tract obstruction.
• The patient experienced symptom relief following the intervention.

Implications:

• Selective angioembolization is a viable and effective alternative to surgery for obstructing renal AML.
• This minimally invasive technique offers a potentially less morbid option for managing symptomatic AML.
• Further research may explore angioembolization as a primary treatment for specific AML presentations.
