Ultrasound (US) is often used to guide various interventional procedures in the genitourinary Epub ahead of print (GU) tract because it can provide real-time imaging without any radiation hazard. Moreover, US can clearly visualize the pathway of an aspiration or biopsy needle to ensure the safety of the intervention. US guidance also helps clinicians to access lesions via the transabdominal, transhepatic, transvaginal, transrectal, and transperineal routes. Hence, US-guided procedures are useful for radiologists who wish to perform GU interventions...

Prostate biopsy is typically performed via either the transrectal or transperineal approach. MRI-targeted biopsy, whether using any of the three options of cognitive fusion, MRI-ultrasound fusion software, or in-bore MRI-guided biopsy, can also be performed via either transrectal or transperineal approaches. As an extension of traditional random prostate biopsy, the transrectal approach is far more commonly used for MRI-targeted biopsy due to its convenience. However, in the context of today's increasing multi-drug resistance of rectal flora, the transperineal approach is being used more often due to its lack of septic complications...

Although febrile complications are rarely encountered after a prostate biopsy procedure, in recent years the number of cases of fatal infection after that have increased along with increases in resistant bacteria. The available biopsy approaches are transrectal and transperineal, with the transrectal approach primarily used. As the invasion path of the puncture needle differs between these approaches, pretreatment and the method of administration of preventive antimicrobial drugs should be separately considered for infection prevention...

BACKGROUND: Despite high rates of disease misclassification and sepsis, the use of transrectal biopsy remains commonplace. Transperineal mapping biopsies mitigate these problems but carry increased cost and patient burden. Local anaesthetic, multiparametric magnetic resonance imaging (MRI)-targeted transperineal biopsy may offer an alternative. Here, we aim to determine the feasibility, tolerability and detection rates of clinically significant prostate cancer using a local anaesthetic, transperineal, MRI-targeted biopsy technique...
