First-in-clinical Evaluation of Dual Contrast-enhanced Ultrasound-guided PCNL: A Multicenter Randomized Trial Versus Fluoroscopy.
BACKGROUND AND OBJECTIVE Puncture is critical in percutaneous nephrolithotomy (PCNL), influencing access failure and vascular or adjacent organ injury. This study aimed to compare the clinical efficacy and safety of dual contrast-enhanced ultrasound (D-CEUS) with fluoroscopic guidance for renal access during PCNL. ME...
