[Radiological methods for visualization of the urinary tract].
The methods of radiologic investigation of the urinary tract have radically altered. Sonography has established itself as the basic method of demonstrating the size and shape of the kidney. Ultrasound reliably identifies cysts among renal tumors. It is increasingly used as the primary method in the search for nephrolithiasis or ureteral stones. Urography offers the highest resolution for the delineation of pathologic changes in the renal pelvis. It is no longer available as a screening method in suspected renovascular hypertension. CT serves to clarify doubtful sonographic renal findings. It is the method of choice for staging of renal tumors and the definition of parenchymal as well as perirenal damage after trauma. Angiography, especially as regards the diagnostic value of digital subtraction angiography, is the diagnostic method of choice in suspected renovascular hypertension. The diagnostic value of magnetic resonance imaging in nephrology and urology cannot yet be finally assessed.
