Grey-scale ultrasound in the imaging of urinary tract disease.
Grey-scale ultrasound defines smaller renal lesions that had previously been appreciated and is able to define associated lesions of the liver such as metastases and cysts. The appropriate technique to delineate the normal anatomy of the kidney is described. Ultrasound plays a central role in the identification and characterization of renal mass lesions thus leading to appropriate further work up. In renal transplant evaluation ultrasound is useful as a complementary modality to other imaging studies permitting the recognition of pelvic fluid collections, rejection, and hydronephrosis. Specific findings are present in renal abscess, perirenal abscess, and in several of the renal cystic diseases. Adrenal lesions can be identified and clarified. In the lower urinary tract, ultrasound can identify bladder and prostatic tumors.Ultrasound provides a rapid, safe and non-invasive modality which is complementary to other imaging techniques in the diagnosis of urinary tract disease.
