[Urinary stone imaging tests.].

Imaging in urolithiasis has a wide group of techniques, with different characteristics, limitations, and indications, which together allow the management of this prevalent pathology. Plain abdominal radiography and ultrasound are very accessible and in expensive techniques that combined present an acceptable sensitivity and specificity. They are widely used for monitoring the evolution of stone disease and for evaluation after treatments (surgery or SWL). Ultrasound is the primary radiological diagnostic tool in the pediatric population and in pregnant women. CT has prevailed over IVP in the anatomical assessment of the urinary tract and the description of the characteristics of the lithiasis, although it shows a greater exposure to ionizing radiation, so the use of low and ultra-low dose CT is spreading. In this article we also discuss other imaging techniques suchas Digital to mosynthesis, Fluoroscopy and DMSA Scintigraphy.
