Objective: To explore the impact of insertion timing of iodophor cotton ball on the control of infection complications after transrectal ultrasound (TRUS) guided prostate biopsy.
Methods: A total of 197 patients undergoing TRUS-guided prostate biopsy from March 2012 to January 2013 were randomly divided into post-discharge, pre-discharge and pre-discharge plus post-discharge groups. A prospective study was made on the symptoms of infections, signs and relevant laboratory examinations in all three groups.
Results: Infections occurred in 6/66 patients in the post-discharge group and 2 patients in the other two groups. The prevalence rates were 7.58%, 3.08% and 3.03% respectively. Statistically significant difference existed in the prevalence rate between pre-discharge and post-discharge groups (P < 0.05). Yet no statistically significant difference existed between pre-discharge and pre-discharge plus post-discharge groups (P > 0.05).
Conclusion: During the TRUS guided prostate biopsy, inserting an iodophor cotton ball before placing an ultrasonic probe to the rectum can control the infection and reduce its prevalence rate.
