Ultrasonography as an Aid in the Diagnosis and Management of Surgical Diseases of the Pelvis

Abstract

Technological advances, particularly the advent of the gray scale technique, has greatly extended the application and usefulness of this modality to clinical diagnoses and surgery. The ultrasonic beam uniquely provides anatomical profiles in the transverse (cross-sectional) and sagittal (longitudinal) planes of the body. Intra-rectal and intra-vaginal ultrasonic probes have provided unique definition of both the normal and pathologic anatomy of the pelvic organs. The present report is drawn from a continuing experience with ultrasonography of the genitourinary system with an update of current technological advances. Ultrasonography has proven especially valuable in the following clinical applications: 1) Early diagnosis of cancer (especially of the prostate); 2) Accurate staging of cancer of the bladder and prostate; 3) Monitoring of the response of the pathologic process to therapy.
