CT Urography for Evaluation of the Ureter

Area of Science:

• Radiology
• Medical Imaging
• Urology

Background:

• Computed tomographic (CT) urography is now the primary imaging method for urinary tract evaluation.
• It is frequently used in the initial assessment of hematuria.
• Understanding normal ureteral anatomy and pathological findings on CT urography is crucial for radiologists.

Purpose of the Study:

• To review normal ureteral anatomy and pathological conditions as seen on CT urography.
• To discuss indications, imaging protocols, and techniques for optimal ureteral evaluation.
• To cover dose reduction strategies for CT urography.

Main Methods:

• Review of current literature and imaging protocols for CT urography.
• Analysis of common and uncommon ureteral pathologies visualized on CT.
• Emphasis on techniques for detailed ureteral assessment.

Main Results:

• CT urography effectively visualizes normal ureteral anatomy.
• Pathologic findings include congenital abnormalities, filling defects, dilatation, narrowing, and deviations.
• Specific protocols enhance the detection of ureteral abnormalities.

Conclusions:

• CT urography is a vital tool for diagnosing ureteral diseases.
• Knowledge of imaging protocols and potential abnormalities is essential for accurate interpretation.
• Dose reduction strategies should be considered during CT urography examinations.
