TRUS, an acronym for Transrectal Ultrasound, refers to a diagnostic imaging technique utilizing sound waves to visualize and produce images of the prostate gland, located near the rectum. The procedure involves inserting a probe, or transducer, into the rectum to obtain a clear and detailed view of the prostate's internal structure and surrounding tissues.
This technique is primarily employed in urology to assess prostate health, screen for cancer, and guide interventions such as biopsies or brachytherapy. TRUS provides real-time imaging, facilitating the identification and measurement of abnormalities, including nodules or tumors, inflammation, cysts, or any enlargement or irregularity of the prostate. By allowing physicians to evaluate the size, shape, and characteristics of the gland, TRUS aids in the diagnosis and staging of prostate cancer, as well as monitoring disease progression or treatment response.
During the TRUS examination, the transducer emits high-frequency sound waves that travel through the rectal wall and bounce back upon encountering different tissues. These echoes are then translated into images, which can be observed on a monitor and interpreted by medical professionals. The procedure is generally considered safe, minimally invasive, and well-tolerated, although some discomfort or pressure sensations might occur. TRUS plays a crucial role in the early detection and management of prostate conditions, contributing to improved patient outcomes and overall care.
