Abstract：Objective:To explore the feasibility and effectiveness of " one-puncture one-needle" transrectal ultrasound (TRUS)-guided prostate biopsy in the prevention of postoperative infections.Methods:We retrospectively analyzed the clinical data about "one-puncture one-needle" (the observation group) and " one-person one-needle" (the control group) TRUS-guided prostate biopsy performed in the Second People's Hospital of Guangdong Province from January 2005 to December 2015,and compared the incidence rates of puncture-related infection between the two strategies.By "one-puncture one-needle",one needle was used for one biopsy puncture,while by "one-person one-needle",one needle was used for all biopsy punctures in one patient and the needle was sterilized with iodophor after each puncture.Results:Totally,120 patients received 6 + 1-core or 12 + 1-core " one-person one-needle" and 466 underwent 12 + 1-core "one-puncture one-needle" TRUS-guided prostate biopsy.There were no statistically significant differences between the two groups of patients in age,the prostate volume,the serum PSA level,or the detection rate of prostate cancer (P ＞ 0.05).Compared with the control group,the observation group showed remarkably lower incidence rates of puncture-related urinary tract infection (7.5 ％ vs 0.9％,P ＜ 0.05),fever (5.0％ vs 1.1％,P ＜ 0.05),bacteriuria (2.5％ vs 0.2％,P ＜ 0.05),and total infections (16.7％ vs 2.6％,P ＜0.05) postoperatively.Two cases of bacteremia or sepsis were found in each of the groups,with no significant difference between the two.Conclusion:"One-puncture one-needle" TRUS-guided prostate biopsy can effectively prevent puncture-related infections.
