Effect of rectal mucosa cleansing on acute prostatitis during prostate biopsy: A randomized prospective study.

OBJECTIVE

Infectious complications after transrectal ultrasound-guided prostate biopsy (TRUS-PB) can range from asymptomatic bacteriuria and febrile or non-febrile urinary tract infection (UTI) to sepsis. Cleaning of rectal mucosa with topical antiseptics such as povidone iodine or chlorhexidine before the procedure are alternative prophylaxis methods. We aimed to investigate the effects of these two different topical antiseptic agents on infectious complications and their superiority to each other.

MATERIAL AND

METHODS

The study was conducted with 200 patients. Rectal mucosa cleansings were performed in 50 patients with povidone iodine and 49 patients with chlorhexidine. The remaining 101 patients did not receive any antiseptic treatment. The results were examined according to the hospital admissions or hospitalization for the first 30 days after the procedure due to UTI, body temperature >38.5°C, sepsis, hematuria, rectal bleeding, and urinary retention.

RESULTS

The mean age of study population was 63.3±7.26 years, and the mean prostate specific antigen value was 13.96±29.5 ng/mL. Acute prostatitis occurred in 14 patients (7%), 9 of whom were hospitalized due to sepsis after TRUS-PB. Statistically significant less acute prostatitis was observed in those patients who were treated with topical rectal antisepsis (topical rectal antisepsis 2% vs. no rectal antisepsis 12.1%, p=0.01). Chlorhexidine and povidone iodine were not superior to each other in terms of inhibiting the development of acute prostatitis (chlorhexidine 2% vs. povidone iodine 2%, p=1.00).

CONCLUSION

Rectal mucosal cleansing with chlorhexidine or povidone iodine before TRUS-PB prevented the development of sepsis due to acute prostatitis. We recommend that this effective method, which is easy to apply, cheap, reliable, easily tolerated should be used in all prostate biopsy practice.
