Nephrolithiasis, once considered an adult condition, is now increasingly prevalent in pediatric populations, leading to flank pain, hydronephrosis, and potential renal failure. Traditional imaging modalities for diagnosing pediatric nephrolithiasis, such as ultrasound and CT, are evolving, with newer protocols (e.g., ultra-low dose CT with tin filtration) being developed. The aim of this study was to design and validate an ex vivo porcine model to simulate pediatric renal stones, providing a substrate for the advancement of imaging techniques in renal stone detection and characterization.

Pediatric nephrolithiasis is on the rise, and as radiologists, we are faced with increasing demand for optimized diagnostic imaging, particularly in ultrasound and CT. We responded to this challenge by developing an ex vivo porcine model designed to simulate pediatric renal stones. This model serves as a testbed for stone detection and characterization via imaging, thereby providing clinicians with the diagnostic information they need to guide treatment. Read More
