The effect of povidone-iodine rectal cleansing on post-biopsy infectious complications.

OBJECTIVE

To evaluate the effect of pre-biopsy povidone-iodine rectal cleansing on post-biopsy hospitalization rates due to prostate biopsy-related infectious complications.

MATERIAL AND

METHODS

In this retrospective study, we reviewed 552 patients who underwent ultrasonography-guided transrectal prostate biopsy between 2014 and 2022. Group 1, 361 patients (January 2014-October 2020) were not applied povidone-iodine rectal cleansing, and group 2, 191 patients (November 2020-January 2022) were applied povidone-iodine rectal cleansing since we changed our biopsy protocol. All patients were given the same antibiotic prophylaxis, ciprofloxacin 500 mg, and ornidazole 500 mg twice daily starting 24 h before the biopsy and lasting a total of 5 days. Sodium phosphate enema was applied to all patients in the biopsy morning. The outcome was the hospitalization rates of patients because of infectious complications a month after the biopsy.

RESULTS

No patients were hospitalized in the povidone-iodine rectal cleansing group because of biopsy related complications. The hospitalization rate of group 1 was 3% and there was a statistical difference between groups.

CONCLUSION

The povidone-iodine solution is cheap, safe and easy to apply. The povidone-iodine rectal cleansing method seems to decrease infectious complications related to prostate biopsy procedure, but we need a randomized controlled trial to confirm our study.

TRIAL REGISTRATION: We got permission for this retrospective study from the Karabuk university ethics council with the number 2021/649 on 1 October 2021.
