Contrast-enhanced Ultrasound Versus CT Scan for Kidney Stone Patient Management

Summary

This study will be a randomized controlled study comparing the use of two clinical management strategies in nephrostomy tube management following percutaneous nephrolithotomy (PCNL). The first strategy entails using contrast-enhanced ultrasound (CEUS) to evaluate the renal collecting system (1). This is a new imaging approach applying ultrasound machines with special software in combination with intraluminal ultrasound contrast agent (Lumason) injection, which is an FDA-approved ultrasound contrast agent (2). The second strategy is a nephrostomy tube capping trial combined with low dose non-contrast computed tomography (CT) scan, one of the most frequently utilized clinical management strategies currently used in clinical practice (3).
