Risk factors for infection and acute urinary retention following transperineal prostate biopsy

Purpose To calculate the frequency of infection and acute urinary retention (AUR) following transperineal (TP) prostate biopsy at a single high-volume academic institution and determine risk factors for developing these post-biopsy conditions. Methods Men undergoing TP prostate biopsy from 2012 to 2...

Description
Summary:Purpose To calculate the frequency of infection and acute urinary retention (AUR) following transperineal (TP) prostate biopsy at a single high-volume academic institution and determine risk factors for developing these post-biopsy conditions. Methods Men undergoing TP prostate biopsy from 2012 to 2022 at our institution were retrospectively identified and chart reviewed. TP biopsies were performed with TR ultrasound (TRUS) guidance with anesthesia using a brachytherapy grid template. TRUS volumes were recorded during the procedure, and magnetic resonance imaging (MRI) volumes were calculated using the ellipsoid formula. When available, MRI volume was used for all analysis, and when absent, TRUS volume was used. AUR was defined as requiring urinary catheter placement within 72 h post-biopsy for inability to urinate. Univariable analysis was performed and variables with p   61.21 cc were three times as likely ( p  = 0.019). Conclusion According to our model, AUR is the greatest risk factor for infection post-TP biopsy. With regard to AUR risks, infection post-biopsy and prostate size > 61.21 cc are the greatest risk factors.
