Special Sono-Case: A Doppler case of suspected renal artery stenosis during pregnancy in a patient with an ectopic kidney.

Why this case matters

Pregnancy changes hemodynamics, and an ectopic kidney may have short, multiple, or atypically originating arteries. A complete study requires adapted windows and cautious interpretation of velocity criteria.

The case covers

• Maternal positioning and pregnancy-safe technique
• Localization of the ectopic kidney and accessory arteries
• Direct and indirect Doppler criteria
• Aortic comparison, limitations, and multidisciplinary reporting
