Gray scale ultrasound and the genitourinary tract. A review of clinical applications.

Diagnostic ultrasound has many well established indications in the evaluation of genitourinary tract disease. Musch of this information complements or corroborates findings derived from other investigations. The role of ultrasound as a primary diagnostic modality is still evolving, but it appears to be useful in a variety of clinical situations, especially in azotemia, suspected hydronephrosis, and renal transplantation. Ultrasound also has a place in the evaluation of the retroperitoneum, the perirenal space, and the adrenal glands, and preliminary work suggests a role in prostatic and testicular abnormalities as well. State of the art prospective comparisons with computed tomography need to be made in many of these areas before the precise role of ultrasound can be defined.
