EMR Search Terms for Renal Ultrasound

If you cannot find "renal ultrasound" in your EMR, search for "US kidney retroperitoneal" or "US kidneys and bladder retroperitoneal" or "US color Doppler kidneys and bladder retroperitoneal"—these are the standardized radiology nomenclature terms used in ordering systems. 1, 2

Alternative Search Terms to Try

Based on ACR (American College of Radiology) standardized terminology, try these exact phrases in your EMR search:

  • "US kidney retroperitoneal with duplex Doppler" - This is the most comprehensive renal ultrasound order and includes Doppler evaluation 1
  • "US kidneys and bladder retroperitoneal" - Standard term for basic renal ultrasound 2
  • "US color Doppler kidneys and bladder retroperitoneal" - Includes vascular assessment 2, 3
  • "Renal sonography" - Alternative medical terminology 4, 5
  • "Kidney ultrasound" - Simplified common term 6, 5
  • "Abdominal ultrasound" - May include kidneys but less specific 2

Why the Terminology Matters

The ACR Appropriateness Criteria use specific standardized nomenclature that most EMR systems adopt for radiology orders 1. The term "US kidney retroperitoneal" is the official designation because it specifies both the organ (kidney) and the anatomic approach (retroperitoneal), distinguishing it from other abdominal imaging 1, 2.

Common Pitfall to Avoid

Do not order "US abdomen" when you specifically need renal imaging 2. US abdomen is a less comprehensive examination of the genitourinary system and may not adequately image the kidneys, particularly if you need to evaluate for hydronephrosis, renal size, echogenicity, or obstruction 2, 6.

When Doppler is Needed

Order the Doppler version ("US kidney retroperitoneal with duplex Doppler") if you are evaluating for: 1

  • Renovascular hypertension or renal artery stenosis
  • Suspected vascular abnormalities
  • Transplant kidney assessment
  • Need for resistive index measurements

Order the standard version ("US kidneys and bladder retroperitoneal") for: 6, 7

  • Screening for hydronephrosis/obstruction
  • Evaluating decreased renal function
  • Assessing kidney size and echogenicity
  • Detecting masses or cysts
