A cost-effective transperineal prostate biopsy method utilizes the original transrectal setting.

purposeTransperineal prostate biopsy (TPB) offers an alternative to transrectal prostate biopsy (TRB) for prostate cancer diagnosis. However, TPB may result in additional disposable and capital equipment costs, which can limit implementation within urology practice. Herein, we report the initial experience of a novel TPB technique within a tertiary referral center in Taiwan. MATERIALS AND

methodsA retrospective review of all men undergoing prostate biopsy January to October in 2021 was performed. Both biopsy techniques were performed with the same setting using the convex-convex array ultrasound probe under local anesthesia alone or with the addition of sedation using double free-hand technique. Complications within 30 days and cancer detection rate (CDR) were compared between the groups.

resultsA total of 118 biopsies were included for final analysis. Eleven patients received systematic biopsy with additional MRI-targeted biopsy (TB) cores with all performed via a transperineal approach. The TPB group (n = 47) and TRB group (n = 58) had similar CDR after excluding TB cores (46.8% vs. 44.8%, p = 0.675). General complication rates for TPB were significantly lower than in the TRB group (27.7% vs. 46.6%, p = 0.047). No patients undergoing TPB had infectious complications, where five episodes were recorded in the TRB group (p = 0.114).

conclusionsTPB performed with convex-convex ultrasound probe and double free-hand technique is safe, feasible, cost-effective, and demonstrates equivalent CDR to TRB. Its use may eliminate infectious hospitalizations while minimizing the need for additional capital in the adoption of TPB.
