Asymptomatic bacteriuria (ASB) is a common finding in many populations, including healthy women and persons with underlying urologic abnormalities. The 2005 guideline from the Infectious Diseases Society of America recommended that ASB should be screened for and treated only in pregnant women or in an individual prior to undergoing invasive urologic procedures. Treatment was not recommended for healthy women; older women or men; or persons with diabetes, indwelling catheters, or spinal cord injury. The guideline did not address children and some adult populations, including patients with neutropenia, solid organ transplants, and nonurologic surgery. In the years since the publication of the guideline, further information relevant to ASB has become available. In addition, antimicrobial treatment of ASB has been recognized as an important contributor to inappropriate antimicrobial use, which promotes emergence of antimicrobial resistance. The current guideline updates the recommendations of the 2005 guideline, includes new recommendations for populations not previously addressed, and, where relevant, addresses the interpretation of nonlocalizing clinical symptoms in populations with a high prevalence of ASB.

Purpose: We identify which nonantibiotic strategies could reduce the risk of infectious complications following prostate biopsy. Materials and Methods: We performed a literature search on MEDLINEÒ, EmbaseÒ and the Cochrane Database for randomized controlled trials (inception to May 2020) assessing nonantibiotic interventions in prostate biopsy. Primary outcome was pooled infectious complications (fever, sepsis and symptomatic urinary tract infection) and secondary outcome was hospitalization. Cochrane risk of bias tool and GRADE approach were used to assess the bias and the certainty of evidence. The study protocol was registered with PROSPERO (CRD42015026354). Results: A total of 90 randomized controlled trials (16,941 participants) were included in the analysis, with 83 trials being categorized into one of 10 different interventions. Transperineal biopsy was associated with significantly reduced infectious complications as compared to transrectal biopsy (RR 0.55, 95% CI 0.33e0.92, p[0.02, I 2 [0%, 1,330 participants, 7 studies). Rectal preparation with povidone-iodine was also shown to reduce infectious complications (RR 0.50, 95% CI 0.38e0.65, p <0.000001, I 2 [27%, 1,686 participants, 8 studies) as well as hospitalization (RR 0.38, 95% CI 0.21e0.69, p[0.002, I 2 [0%, 620 participants, 4 studies). We found no difference in infectious complications/hospitalization for 6 other interventions, ie number of biopsy cores, periprostatic nerve block, number of injections for periprostatic nerve block, needle guide type, needle type and rectal preparation with enema. In 2 interventions (needle diameter, rectal preparation with chlorhexidine) meta-analysis was not possible. Finally, 7 studies had unique interventions. The certainty of evidence was rated as low/ very low for all interventions. Conclusions: Transperineal biopsy significantly reduces infectious complications compared to transrectal biopsy and should therefore be preferred. If transrectal biopsy is performed, rectal preparation with povidone-iodine is highly recommended. The other investigated nonantibiotic strategies did not significantly influence infection and hospitalization after prostate biopsy.

Purpose: Infectious complications following prostate biopsy are increasing and fluoroquinolone prophylaxis has recently been banned by the European Commission. In this systematic review we summarize the evidence for different antibiotic prophylaxis regimens. Materials and Methods: We searched MEDLINEÒ, EmbaseÒ and Cochrane Database for randomized controlled trials (inception to October 2019) assessing antimicrobial interventions in prostate biopsy. Primary outcome was infectious complications. Exclusion criteria were simultaneous interfering interventions. GRADE (Grading of Recommendations, Assessment, Development and Evaluations) was used to assess the certainty of evidence. Protocol was registered with PROSPERO (CRD42015026354). Results: Overall 59 randomized controlled trials (14,153 participants) and 7 different antimicrobial interventions were included. Antibiotic prophylaxis reduced infectious complications compared to no prophylaxis (RR 0.56, 95% CI 0.40e0.77, p[0.0005, I 2 [15%, participants 1,753, studies 11). A short-term prophylaxis (single shot to 3 days) was inferior to a long-term prophylaxis (1 to 7 days) with fluoroquinolone (RR 1.89, 95% CI 1.37e2.61, p[0.0001, I 2 [0%, participants 3,999, studies 17). Fosfomycin trometamol was an alternative to fluoroquinolone with reduced rates of infectious complications (RR 0.49, 95 CI 0.27e0.87, p[0.02, I 2 [54%, participants 1,239, studies 3). Empiric prophylaxis was inferior to targeted prophylaxis (RR 1.81, 95% CI 1.28e2.55, p[0.0008, I 2 [48%, participants 1,511, studies 6). Standard prophylaxis was inferior to augmented prophylaxis (using multiple rather than single agent) using a fixed model (RR 2.10, 95% CI 1.53e2.88, p <0.0001, I 2 [71%, participants 2,597, studies 9), but not using a random model (p[0.07). No difference was observed in infectious complications based on route or timing of antimicrobial prophylaxis. The certainty of evidence was rated as low/very low. Conclusions: In countries where fluoroquinolones are allowed as antibiotic prophylaxis, a minimum of a full 1-day administration as well as targeted therapy in case of fluoroquinolone resistance is recommended.
