[Intrarectal povidone-iodine to reduce the risk of genitourinary infections after transrectal prostate biopsy].

BACKGROUND

The aim of this study is to compare two different preparations in patients undergoing transrectal prostate biopsies samples (TPBS) and assess the prevalence of genitourinary infections (GUI).

METHODS

A historical cohort of patients undergoing TBPS for suspected prostate cancer. Two groups were compared: one with endorectal lubricant jelly and another with the addition of a povidone-iodine lubricating jelly. Complications were evaluated at three weeks. A bivariate analysis was performed by calculating the OR (95 % CI) to determine if the additional endorectal povidone-iodine pre-TBPS reduced GUI and other complications.

RESULTS

185 patients (Group I n = 86, Group II n = 96) were evaluated. 45 and 25 % had genitourinary tract infection (OR: 0.4, CI: 0.2-0.9, p = 0.004); fever was presented in 21 and 10 % respectively (OR: 0.42, CI: 0.1-0.9, p = 0.04).

CONCLUSIONS

A reduction was observed in the presence of genitourinary infections in patients who had intrarectal povidone-iodine preparation applied.
