Michael A. Gorin, MD, discusses transperineal fusion biopsy as a viable alternative to transrectal prostate biopsy and its complications. He emphasizes the gravity of the risk of infection, given the large number of prostate biopsies performed.

Dr. Gorin then displays American Urological Association (AUA) recommendations for infection avoidance, highlighting the strategy of transperineal biopsy. He explains that the European Association of Urology (EAU) recommends transperineal biopsy as the first choice for infection avoidance, citing data from a meta-analysis that show a decrease in complications with transperineal biopsies versus transrectal biopsies by more than half.

Further, he shares data showing improved detection of anterior tumors with transperineal biopsy and explains the positioning of the biopsy cores in transperineal biopsy is superior to that of transrectal biopsy. Dr. Gorin shares further data illustrating improved cancer detection with transperineal biopsy before turning to methods of performing transperineal prostate biopsy. 

Dr. Gorin addresses magnetic resonance imaging (MRI) targeting, explaining that as of 2020, the AUA endorses the use of pre-biopsy MRI. He displays data showing improved cancer detection with MRI-targeted biopsy and addresses cognitive fusion and explains that a lack of mapping cores is a drawback but explains that today, there are many options for transperineal MRI/transrectal ultrasound (TRUS) fusion prostate biopsy that include grid, mini-grid, and freehand elements.

Dr. Gorin concludes that transrectal prostate biopsy carries a significant risk of infectious complications and transperineal prostate biopsy reduces these risks and can be performed under local anesthesia. Additionally, multiple systems are available to perform transperineal prostate biopsy with TRUS/MRI fusion.
