Bottom Line: It is a commonly used initial diagnostic imaging modality as it is rapid, effective, portable, relatively inexpensive, and causes no harm to human health.In the last few decades, there have been significant technological improvements in the equipment as well as the development of contrast agents that allowed ultrasound to be even more widely adopted for urologic imaging.Ultrasound is an excellent guidance tool for an array of urologic interventional procedures and also has therapeutic application in the form of high-intensity focused ultrasound (HIFU) for tumor ablation.

ABSTRACT
Ultrasound is an imaging technology that has evolved swiftly and has come a long way since its beginnings. It is a commonly used initial diagnostic imaging modality as it is rapid, effective, portable, relatively inexpensive, and causes no harm to human health. In the last few decades, there have been significant technological improvements in the equipment as well as the development of contrast agents that allowed ultrasound to be even more widely adopted for urologic imaging. Ultrasound is an excellent guidance tool for an array of urologic interventional procedures and also has therapeutic application in the form of high-intensity focused ultrasound (HIFU) for tumor ablation. This article focuses on the recent advances in ultrasound technology and its emerging clinical applications in urology.

Mentions: CEUS is useful for characterizing focal renal lesions[202122] [Figures 4 and 5]. Renal cell carcinomas (RCCs) are the most common malignant renal neoplasm. On CEUS, RCCs typically show heterogeneous hypervascularity, with an early washout on the delayed phase. A pseudocapsule may be present.[23] Oncocytoma is the most common benign solid renal tumor; however, it shares many imaging features of RCC. On conventional ultrasound, angiomyolipomas (AMLs) are hyperechoic. On CEUS, these lesions tend to enhance peripherally and show less enhancement than the normal cortical renal parenchyma in its central part.[23] Emilio Quaia et al. found that the overall diagnostic accuracy of CEUS was significantly better than unenhanced sonography or CT in the diagnosis of malignancy in complex cystic renal masses.[24]
