Abstract

Background: Transrectal ultrasound-guided prostate biopsy (TRUS-guided biopsy) remains widely used for the diagnosis of prostate cancer, but it is associated with a risk of infectious complications despite antibiotic prophylaxis.

Objectives: To evaluate the effect of disinfecting the prostate biopsy needle with different antiseptic agents after each core sampling on post-procedural infectious complications.

Design: A prospective, randomized, single-center clinical study.

Methods: Between February and May 2025, 240 patients undergoing TRUS-guided prostate biopsy were randomly assigned to four groups (n = 60 each): no needle disinfection, povidone-iodine disinfection, 10% formalin disinfection, or 70% isopropyl alcohol disinfection after each biopsy core. All patients received standardized empirical antibiotic prophylaxis based on the institutional protocol and local antibiogram data. Prophylaxis consisted of oral cefixime initiated on the day of biopsy and continued for 5-7 days. Patients were actively followed for 30 days for febrile urinary tract infection, hospitalization, sepsis, and microbiological culture results.

Results: The rate of febrile urinary tract infection was highest in the non-disinfection group (11.6%). No cases of fever, hospitalization, or sepsis were observed in the formalin group. Povidone-iodine and isopropyl alcohol disinfection were associated with lower infection rates than no disinfection, but were less effective than formalin. Escherichia coli was the most frequently isolated microorganism in positive cultures.

Conclusion: Disinfection of the biopsy needle after each core sampling is associated with a meaningful reduction in infectious complications following TRUS-guided prostate biopsy. Among the evaluated agents, 10% formalin demonstrated the greatest protective effect; however, further multicenter studies with longer follow-up are required to confirm long-term safety and generalizability.

Trial registration: This trial was prospectively registered at ClinicalTrials.gov (Identifier: NCT06836271; Local trial ID: HititUrology001).

一项前瞻性随机研究:不同消毒剂对超声引导前列腺活检后感染并发症的影响
背景:经直肠超声引导前列腺活检(trus引导活检)仍然广泛用于前列腺癌的诊断,但它与感染并发症的风险相关,尽管抗生素预防。目的:评价每次取芯后用不同消毒剂对前列腺活检针消毒对术后感染并发症的影响。设计:前瞻性、随机、单中心临床研究。方法:于2025年2月至5月,将240例行超声引导前列腺活检的患者随机分为4组(每组60例):活检芯后无针消毒、聚维酮碘消毒、10%福尔马林消毒、70%异丙醇消毒。所有患者均根据机构方案和当地抗生素谱数据接受标准化的经验性抗生素预防。预防包括在活检当天开始口服头孢克肟并持续5-7天。积极随访患者30天,观察发热性尿路感染、住院、败血症和微生物培养结果。结果:未消毒组发热性尿路感染发生率最高(11.6%)。福尔马林组未出现发热、住院或败血症病例。聚维酮碘和异丙醇消毒的感染率低于不消毒,但效果不如福尔马林。大肠杆菌是阳性培养中最常见的分离微生物。结论:每次取样后对活检针进行消毒,可显著减少超声引导下前列腺活检后的感染并发症。在评价剂中,10%福尔马林的保护效果最好;然而,需要进一步的多中心研究和更长的随访时间来确认长期的安全性和普遍性。试验注册:本试验在ClinicalTrials.gov上前瞻性注册(标识符:NCT06836271;本地试验ID: hitirology001)。
