Ultrasonography is a commonly used radiographic technique in patients who present with kidney disease because of its safety, its ease of use, and the information this modality provides. Because obstruction is a readily reversible disorder, all patients who present with acute or chronic failure of unknown etiology should undergo ultrasonography, the modality of choice to assess possible obstructive disease. Although less sensitive than computed tomography (CT) scanning in initially revealing a renal mass, ultrasonography can be useful in differentiating a simple benign cyst from a more complex cyst or a solid tumor. This technique is also commonly used to screen for and to diagnose types of polycystic kidney disease.
