Infectious Outcomes of Povidone-iodine Rectal Cleansing Plus Formalin Disinfection of Needle During Prostate Biopsy

The main purpose of this study is to compare the infectious outcomes of intrarectal povidone-iodine cleansing plus formalin disinfection of needle tip during transrectal ultrasound guided prostate biopsy. The secondary objective is to evaluate predictive factors of infectious complications after prostate biopsy. Data will be prospectively collected from patients who will undergo prostate biopsy in a single high volume urology center. The patients will be randomized to two different groups: group A - rectal cleansing and disinfection of the needle tip vs group B - controls.
