Transrectal Ultrasound: A Key Diagnostic Tool in Urology
Transrectal ultrasound (TRUS) has become an indispensable imaging technique in modern urology. It uses sound waves to create detailed images of the prostate gland and surrounding tissues, allowing physicians to detect abnormalities such as enlargement, inflammation, or tumors. Unlike other imaging methods, TRUS offers real-time visualization, making it especially useful for guiding prostate biopsies with precision.
The procedure is minimally invasive and typically performed in an outpatient setting. A lubricated ultrasound probe is gently inserted into the rectum to capture cross-sectional images. These images help assess prostate size, detect calcifications, and identify suspicious nodules that may indicate cancer. TRUS also assists in evaluating male infertility by analyzing seminal vesicles and ejaculatory ducts.
Advancements in ultrasound technology have made the process more comfortable and efficient. High-frequency transducers now provide clearer resolution, and software enhancements enable better interpretation of results. Moreover, the combination of TRUS with Doppler imaging helps visualize blood flow…
