Infectious complications after transrectal ultrasound-guided prostatic biopsy. Analysis of our experience.

Objectives: To establish the rate of infectious complications derived from the use of transrectal ultrasound-guided prostate biopsy (TRUS), identify its microbiological profile and related risk factors.

Methods: We designed a prospective non-randomized study in which we enrolled 220 patients undergoing TRUS biopsy at our centre between April and September 2008. The inclusion criteria were: suspicious digital rectal examination, PSA >10 ng/ml, and free/total ratio of PSA is assessed in patients with PSA 4-10 ng/ml.
