Impact of insertion timing of iodophor cotton ball on the control of infection complications after transrectal ultrasound guided prostate biopsy

目的 探讨碘伏棉球的放置时机在预防经直肠超声（TRUS）引导下前列腺活检术后感染中的作用.方法 将2012年3月至2013年1月行TRUS引导下前列腺活检术的197例患者,数字随机分为碘伏棉球后放组66例、前放组66例、前放＋后放组65例,前瞻性研究3组患者活检术后感染相关症状、体征及实验室检查,分析不同时机直肠内放置碘伏棉球对控制术后感染发生率的影响.结果 后放组中6例发生感染,前放组及前放＋后放组中各有2例患者发生感染,3组患者感染发生率分别为9.09%（6/66）、3.03%（2/66）、3.08%（2/65）.后放组与前放组及前放＋后放组间感染发生率差异均有统计学意义（均P＜0.05）,前放组与前放＋后放组间差异无统计学意义（P＞0.05）.结论 经TRUS引导下前列腺活检术中,在置入腔内超声探头前于直肠内放入碘伏棉球可在一定程度上预防感染的发生,降低感染发生率.

Objective To explore the impact of insertion timing of iodophor cotton ball on the control of infection complications after transreetal 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 〉 O. 05 ）. Conclusion During the TRUS guided prostate biopsy, inserting an iodophor cotton ball before placing an ultrasonic probento the rectum can control the infection and reduce its prevalence rate.
