Residual Intravenous Contrast Mimicking a Ureteral Stent on Noncontrast Computed Tomography in a Patient With Ureterolithiasis

Puntos clave

• Findings indicate that residual intravenous contrast appears similar to a ureteral stent on computed tomography scans, causing potential misdiagnoses.
• Notable evidence shows this occurrence can complicate the assessment of urinary tract conditions, especially in patients with known ureterolithiasis.
• Analysis of imaging records highlights the challenge of distinguishing between actual stents and residual contrast media in diagnostic imaging.
• Implications suggest that clinicians should remain cautious regarding contrast interpretations on noncontrast computed tomography for accurate diagnosis.
