Ultrasonic Evaluation of Renal Diseases / 대한비뇨기과학회지

ABSTRACT

Ultrasonography is a useful diagnostic modality in evaluating the non-visualized kidney on IVP because visualization by this technique depends only on the morphologic and acoustic characteristics of the kidney and is independent of renal function. This non-invasive technique can accurately guide percutaneous puncture of the collecting system, permitting antegrade localization of the obstructing lesion, and percutaneous nephrostomy under the ultrasonic guidance can be performed as a means for rapid, usually temporary, urinary diversion in patients with obstructive uropathy. Many causes of IVP non-visualization have a typical sonographic appearance. 35 patients with non-visualized kidney were examined ultrasonically and 13 AGP were carried out.
