Michael A. Gorin, MD, presented “Crossing the Divide from Transrectal to Transperineal Biopsy” for the Grand Rounds in Urology audience in June, 2020.

Presentation Summary:

Michael A. Gorin, MD, a urologist at Urology Associates of Cumberland, Maryland, and Director of Medical Affairs for Perineologic, discusses the benefits of transperineal prostate biopsy over transrectal biopsy. He notes that transrectal prostate biopsy leads to infections in 5-7% of patients, and argues that transperineal biopsy is the best alternative for avoiding infection. Dr. Gorin acknowledges that the use of a grid-stepper unit for performing transperineal biopsy can be uncomfortable for patients, but suggests that new technology and techniques like the PrecisionPoint™ Transperineal Access System solve many of these issues. The presentation is followed by a Q&A in which Dr. Gorin discusses the importance of new coding for transperineal biopsy and the potential of variable length needles.

Disclosures: Dr. Gorin is a consultant for Perineologic.

Q&A – Summary:

E. David Crawford, MD, interviews Michael A. Gorin, MD, on advances in transperineal prostate biopsy. When asked to predict what percentage of prostate biopsies will be performed transperineally in a year, Dr. Gorin opines that wider adoption of the technique will require a new insurance code, since it is currently billed under the same code as transrectal biopsy and doctors are therefore less well-compensated. Drs. Gorin and Crawford then discuss a new 3DBiopsy™ variable-length needle currently in development that Dr. Gorin suggests is critical for both transrectal and transperineal biopsy since it will allow urologists to take longer cores. Dr. Gorin concludes by affirming his commitment to teaching fellow urologists about transperineal biopsy.
