Endoluminal ultrasonography (ELUS) is a noninvasive diagnostic technique used in urology to image tubular structures of the urinary tract. Through advancements in technology, modern ELUS is able to create three-dimensional images, which provide valuable clinical information for the diagnosis and treatment of urologic disorders. The efficiency and accuracy of this technology is confirmed through validation studies using human and animal models. Although a relatively new method, the clinical application of this technique holds great promise in the field of endourology. The technology, advantages, limitations, validation studies, clinical applications, and future of ELUS are explored through this comprehensive review of current urologic literature.
