Transrectal ultrasound (TRUS) is a valuable tool for assessing the prostate and aiding in prostate cancer diagnosis. It can be used in both transrectal and transperineal biopsy approaches with similar detection rates, but different rates of infection and urinary retention. Multiparametric MRI has substantial benefits for prostate cancer diagnosis and can be combined with TRUS for fusion biopsies. Micro-ultrasound provides higher resolution images and is effective at diagnosing prostate cancer. High-intensity focused ultrasound therapy administered via TRUS shows promise for localized disease treatment.
Transrectal ultrasound (TRUS) has been an invaluable tool in the assessment of prostate size, anatomy and aiding in prostate cancer (PCa) diagnosis for decades. Emerging techniques warrant an investigation into the efficacy of TRUS, how it compares to new techniques, and options to increase the accuracy of prostate cancer diagnosis. Currently, TRUS is used to guide both transrectal and transperineal biopsy approaches with similar cancer detection rates, but lower rates of infection have been reported with the transperineal approach, while lower rates of urinary retention are often reported with the transrectal approach. Multiparametric MRI has substantial benefits for prostate cancer diagnosis and triage such as lesion location, grading, and can be combined with TRUS to perform fusion biopsies targeting specific lesions. Micro-ultrasound generates higher resolution images that traditional ultrasound and has been shown effective at diagnosing PCa, giving it the potential to become a future standard of care. Finally, high-intensity focused ultrasound focal therapy administered via TRUS has been shown to offer safe and effective short-term oncological control for localized disease with low morbidity, and the precise nature makes it a viable option for salvage and repeat therapy.
