Evaluation of the Forsvall biopsy needle in anex vivomodel of transrectal prostate biopsy – a novel needle design with the objective to reduce the risk of post-biopsy infection

Transrectal prostate biopsy (TRbx) transfers colonic bacteria into prostatic tissue, potentially causing infectious complications, including sepsis. Our objective was to determine whether biopsy needle shape, surface properties and sampling mechanism affect the number of bacteria transferred through the colon wall, and evaluate a novel needle with improved properties.The standard Tru-Cut biopsy needle used today was evaluated for mechanisms of...
