High-yield and rapid isolation of extracellular vesicles by flocculation via orbital acoustic trapping: FLOAT. MICROSYSTEMS & NANOENGINEERING 2024; 10:23. [PMID: 38317693 PMCID: PMC10838941 DOI: 10.1038/s41378-023-00648-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 11/01/2023] [Accepted: 11/11/2023] [Indexed: 02/07/2024]
Abstract
Extracellular vesicles (EVs) have been identified as promising biomarkers for the noninvasive diagnosis of various diseases. However, challenges in separating EVs from soluble proteins have resulted in variable EV recovery rates and low purities. Here, we report a high-yield ( > 90%) and rapid ( < 10 min) EV isolation method called FLocculation via Orbital Acoustic Trapping (FLOAT). The FLOAT approach utilizes an acoustofluidic droplet centrifuge to rotate and controllably heat liquid droplets. By adding a thermoresponsive polymer flocculant, nanoparticles as small as 20 nm can be rapidly and selectively concentrated at the center of the droplet. We demonstrate the ability of FLOAT to separate urinary EVs from the highly abundant Tamm-Horsfall protein, addressing a significant obstacle in the development of EV-based liquid biopsies. Due to its high-yield nature, FLOAT reduces biofluid starting volume requirements by a factor of 100 (from 20 mL to 200 µL), demonstrating its promising potential in point-of-care diagnostics.

Patient Reported Outcomes of Transperineal Prostate Biopsy With Tumescent Local Anesthesia. Urology 2023; 182:33-39. [PMID: 37742847 DOI: 10.1016/j.urology.2023.09.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Revised: 08/01/2023] [Accepted: 09/12/2023] [Indexed: 09/26/2023]
Abstract
OBJECTIVE To report the outcomes of performing transperineal prostate biopsy in the office setting using the novel anesthetic technique of tumescent local anesthesia. We report anxiety, pain, and embarrassment of patients who underwent this procedure compared to patients who underwent a transrectal prostate biopsy using standard local anesthesia. MATERIALS AND METHODS Consecutive patients undergoing either a transperineal prostate biopsy under tumescent local anesthesia or a transrectal prostate biopsy with standard local anesthetic technique were prospectively enrolled. The tumescent technique employed dilute lidocaine solution administered using a self-filling syringe. Patients were asked to rate their pain before, during, and after their procedure using a visual analog scale. Patient anxiety and embarrassment was assessed using the Testing Modalities Index Questionnaire. RESULTS Between April 2021 and June 2022, 430 patients underwent a transperineal prostate biopsy using tumescent local anesthesia and 65 patients underwent a standard transrectal prostate biopsy. Patients who underwent a transperineal biopsy had acceptable but significantly higher pain scores than those who underwent a transrectal prostate biopsy (3.9 vs 1.6, P-value <.01). These scores fell to almost zero immediately following their procedure. Additionally, transperineal biopsy patients were more likely to experience anxiety (71% vs 45%, P < .01) and embarrassment (32% vs 15%, P < .01). CONCLUSION Transperineal biopsy using local tumescent anesthesia is safe and well-tolerated. Despite the benefits, patients undergoing a transperineal prostate biopsy under tumescent anesthesia still experienced worse procedural pain, anxiety, and embarrassment. Additional studies examining other adjunctive interventions to improve patient experience during transperineal prostate biopsy are needed.

Abstract
PURPOSE Transperineal prostate biopsy (TPB) offers an alternative to transrectal prostate biopsy (TRB) for prostate cancer diagnosis. However, TPB may result in additional disposable and capital equipment costs, which can limit implementation within urology practice. Herein, we report the initial experience of a novel TPB technique within a tertiary referral center in Taiwan. MATERIALS AND METHODS A retrospective review of all men undergoing prostate biopsy January to October in 2021 was performed. Both biopsy techniques were performed with the same setting using the convex-convex array ultrasound probe under local anesthesia alone or with the addition of sedation using double free-hand technique. Complications within 30 days and cancer detection rate (CDR) were compared between the groups. RESULTS A total of 118 biopsies were included for final analysis. Eleven patients received systematic biopsy with additional MRI-targeted biopsy (TB) cores with all performed via a transperineal approach. The TPB group (n = 47) and TRB group (n = 58) had similar CDR after excluding TB cores (46.8% vs. 44.8%, p = 0.675). General complication rates for TPB were significantly lower than in the TRB group (27.7% vs. 46.6%, p = 0.047). No patients undergoing TPB had infectious complications, where five episodes were recorded in the TRB group (p = 0.114). CONCLUSIONS TPB performed with convex-convex ultrasound probe and double free-hand technique is safe, feasible, cost-effective, and demonstrates equivalent CDR to TRB. Its use may eliminate infectious hospitalizations while minimizing the need for additional capital in the adoption of TPB.

Abstract
Prostate cancer (PCa) faces great challenges in early diagnosis, which often leads not only to unnecessary, invasive procedures, but to over-diagnosis and treatment as well, thus highlighting the need for modern PCa diagnostic techniques. The review aims to provide an up-to-date summary of chronologically existing diagnostic approaches for PCa, as well as their potential to improve clinically significant PCa (csPCa) diagnosis and to reduce the proliferation and monitoring of PCa. Our review demonstrates the primary outcomes of the most significant studies and makes comparisons across the diagnostic efficacies of different PCa tests. Since prostate biopsy, the current mainstream PCa diagnosis, is an invasive procedure with a high risk of post-biopsy complications, it is vital we dig out specific, sensitive, and accurate diagnostic approaches in PCa and conduct more studies with milestone findings and comparable sample sizes to validate and corroborate the findings.

Abstract
INTRODUCTION Robot-assisted devices have been recently developed for use in prostate biopsy. However, it is possible advantages over standard biopsy remain unclear. We aimed to assess the diagnostic performance and safety of robot-assisted targeted (RA-TB) and systematic prostate biopsies (RA-SB). METHODS A systematic literature search was performed in MEDLINE and Scopus databases. The detailed search strategy is available at Prospero (CRD42021269290). The primary outcome was the clinically significant prostate cancer (PCa) detection rate. The secondary outcomes included the overall detection rate of PCa, cancer detection rate per core, and complications. RESULTS The clinically significant cancer detection rate, overall cancer detection rate, and "per patient" did not significantly differ between RA-TB and RA-SB [OR = 1.02 (95% CI 0.83; 1.26), p = 0.05, I2 = 62% and OR = 0.95 (95% CI 0.78; 1.17), p = 0.17, I2 = 40%, respectively]. There were no differences in the clinically insignificant cancer detection rate "per patient" between RA-TB and RA-SB [OR = 0.81 (95% CI 0.54; 1.21), p = 0.31, I2 = 0%]. RA-TB had a significantly higher cancer detection rate "per core" [OR = 3.01 (95% CI 2.77; 3.27), p < 0.0001, I2 = 96%]. CONCLUSION RA-TB and RA-SB are both technically feasible and have comparable clinical significance and overall PCa detection rates.

Abstract
Approaches and techniques used for diagnostic prostate biopsy have undergone considerable evolution over the past few decades: from the original finger-guided techniques to the latest MRI-directed strategies, from aspiration cytology to tissue core sampling, and from transrectal to transperineal approaches. In particular, increased adoption of transperineal biopsy approaches have led to reduced infectious complications and improved antibiotic stewardship. Furthermore, as image fusion has become integral, these novel techniques could be incorporated into prostate biopsy methods in the future, enabling 3D-ultrasonography fusion reconstruction, molecular targeting based on PET imaging and autonomous robotic-assisted biopsy.

Abstract
Background Infectious complications after a transrectal prostate biopsy may be severe. In Sweden, a routine culture prior to all prostate biopsies was introduced to enable targeted antimicrobial prophylaxis and reduce postbiopsy infections. Objective To investigate whether a clinical routine with a urine culture prior to a prostate biopsy and targeted prophylactic antibiotic therapy reduces postbiopsy infections. Design setting and participants In 2015, a site-specific antimicrobial stewardship programme with a urine culture prior to a prostate biopsy was initiated in Region Kronoberg. To evaluate this routine, we designed a population-based register study including all men who had an outpatient prostate biopsy in 2015-2019 and a control period including all men who had a biopsy in 2010-2014, when a urinary culture was obtained only on clinical suspicion. Outcome measurements and statistical analysis The primary outcome was infectious complications within 10 d and the secondary outcome was a change in antibiotic prophylactic treatment. An infectious complication was defined as prescription of antibiotics for urinary tract infections or admission to hospital for urinary tract infections or sepsis after a biopsy. Results and limitations The urine culture period included 2971 prostate biopsy procedures, of which 2684 (90%) were preceded by a urine culture. The control period included 2818 procedures, of which 135 (4.8%) were preceded by a urine culture. Infectious complications were slightly more common during the urine culture period (5.0%) than during the control period (4.3%, p = 0.17), as was inpatient care for infections (3.5% vs 2.2%, p = 0.002). The routine identified 5.4% men with asymptomatic bacteriuria. Despite targeted antibiotic treatment (1.5% received a nonfluoroquinolone treatment), the rate of infectious complications (6.3%) was similar to that in the control period. Conclusions Prebiopsy urine culture did not lead to fewer postbiopsy infections. Other measures are needed to reduce infectious complications after a prostate biopsy. Patient summary In this report, we evaluated a routine with urine culture prior to a transrectal prostate biopsy and found that it did not lead to fewer infectious complications.

Fosfomycin Trometamol for the Prevention of Infectious Complications After Prostate Biopsy: A Consensus Statement by an International Multidisciplinary Group. Eur Urol Focus 2022; 8:1483-1492.

Abstract
CONTEXT Transrectal ultrasound-guided prostate biopsy (TRPB) has been a standard of care for diagnosing prostate cancer but is associated with a high incidence of infectious complications. OBJECTIVE To achieve an expert consensus on whether fosfomycin trometamol provides adequate prophylaxis in TRPB and discuss its role as prophylaxis in transperineal prostate biopsy (TPPB). EVIDENCE ACQUISITION An international multidisciplinary group of experts convened remotely to discuss how to best use fosfomycin in various clinical settings and patient situations. Six statements related to prostate biopsy and the role of fosfomycin were developed, based on literature searches and relevant clinical experience. EVIDENCE SYNTHESIS Consensus was reached for all six statements. The group of experts was unanimous regarding fosfomycin as a preferred candidate for antimicrobial prophylaxis in TRPB. Fosfomycin potentially also meets the requirements for empiric prophylaxis in TPPB, although further clinical studies are needed to confirm or refute its utility in this setting. There is a risk of bias due to sponsorship by a pharmaceutical company. CONCLUSIONS Antimicrobial prophylaxis is mandatory in TRPB, and fosfomycin trometamol is an appropriate candidate due to low rates of resistance, a good safety profile, sufficient prostate concentrations, and demonstrated efficacy in reducing the risk of infectious complications following TRPB. PATIENT SUMMARY Patients undergoing transrectal ultrasound-guided prostate biopsy (TRPB) have a high risk of infectious complications, and antimicrobial prophylaxis is mandatory. However, increasing antimicrobial resistance, as well as safety concerns with fluoroquinolones, has restricted the number of antimicrobial options. Fosfomycin trometamol meets the requirements for a preferred antimicrobial in the prophylaxis of TRPB.

Prevalence of Plasmid-Mediated Quinolone Resistance (PMQRs) Determinants and Whole Genome Sequence Screening of PMQR-Producing E. coli Isolated from Men Undergoing a Transrectal Prostate Biopsy. Int J Mol Sci 2022; 23:ijms23168907. [PMID: 36012180 PMCID: PMC9408980 DOI: 10.3390/ijms23168907] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 07/29/2022] [Accepted: 08/05/2022] [Indexed: 11/30/2022] Open
Abstract
Fluoroquinolones (FQs) are recommended as prophylaxis for men undergoing transrectal prostate biopsy (TRUS-Bx). Recent studies suggest a significant share of FQ-resistant rectal flora in post-TRUST-Bx infections. Methods: 435 Enterobacterales isolates from 621 patients attending 12 urological departments in Poland were screened by PCR for PMQR genes. PMQR-positive isolates were tested for quinolone susceptibility and investigated by whole genome sequencing (WGS) methods. Results: In total, 32 (7.35%) E. coli strains with ciprofloxacin MIC in the range 0.125–32 mg/L harbored at least one PMQR gene. qnrS and qnrB were the most frequent genes detected in 16 and 12 isolates, respectively. WGS was performed for 28 of 32 PMQR-producing strains. A variety of serotypes and sequence types (STs) of E. coli was noticed. All strains carried at least one virulence gene. AMR genes that encoded resistance against different classes of antibiotics were identified. Additionally, five of 13 ciprofloxacin-susceptible E. coli had alterations in codon 83 of the GyrA subunits. Conclusion: This study provides information on the common presence of PMQRs among E. coli, which may explain the cause for development of post-TRUS-Bx infections. High numbers of virulence and antimicrobial resistance genes detected show a potential for analysed strains to develop infections.

Comparison of Fluoroquinolones and Other Antibiotic Prophylaxis Regimens for Preventing Complications in Patients Undergoing Transrectal Prostate Biopsy. Antibiotics (Basel) 2022; 11:antibiotics11030415. [PMID: 35326878 PMCID: PMC8944856 DOI: 10.3390/antibiotics11030415] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2022] [Revised: 03/16/2022] [Accepted: 03/18/2022] [Indexed: 01/26/2023] Open
Abstract
Our study aimed to compare the incidence of infective complications after transrectal ultrasound-guided prostate biopsy (TRUSBx) when adopting different antimicrobial prophylaxis regimens. A multi-institutional cohort of 1150 patients who underwent TRUSBx was retrospectively analyzed. Procedures were performed between 2017 and 2019 (before and after the EMA warning about the use of fluoroquinolones for the antibiotic prophylaxis of patient candidates to TRUSBx). The primary endpoint was the occurrence of infective complications, including sepsis and/or fever. The population was stratified according to the antibiotic prophylaxis adopted: fluoroquinolones (levofloxacin, ciprofloxacin, prulifloxacin), cephalosporins (cefixime, ceftriaxone) or trimethoprim/sulfamethoxazole. Univariable and multivariable binomial logistic regression models were used to assess the odds ratio (OR) with 95% confidence interval (CI) testing of the risk of infective complication after adjusting for each prebiopsy covariate. In total, 478 (41.6%) patients received fluoroquinolone-based prophylaxis. Among these, 443 (38.5%), 25 (2.2%) and 10 (0.9%) patients received levofloxacin prophylaxis, ciprofloxacin and prulifloxacin, respectively while 14.6% received cefixime, 20.7% received the comedication of ceftriaxone/fosfomycin and 23.1% received trimethoprim/sulfamethoxazole. The trimethoprim/sulfamethoxazole and fluoroquinolone regimens were significantly associated with a lower risk of infective complications (OR 0.15, 95% CI 0.03−0.48, p = 0.003 and OR 0.17, 95% CI 0.06−0.43, p < 0.001, respectively). The ceftriaxone/fosfomycin (OR 0.21, 95% CI 0.04−0.92, p = 0.04) and fluoroquinolone (OR 0.07, 95% CI 0.00−0.70, p = 0.048) prophylaxis were associated with a lower risk of infective sequelae. Fluoroquinolone-based prophylaxis was associated with a lower risk of infective complications after TRUSBx compared to other prophylaxis regimens although its clinical application was recently forbidden by European Medical Agency restrictions.

Comprehensive analysis of complications after transperineal prostate biopsy without antibiotic prophylaxis: results of a multicenter trial with 30 days' follow-up. Prostate Cancer Prostatic Dis 2022; 25:264-268. [PMID: 34267332 PMCID: PMC9184280 DOI: 10.1038/s41391-021-00423-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2021] [Revised: 06/21/2021] [Accepted: 06/28/2021] [Indexed: 12/02/2022]
Abstract
BACKGROUND To investigate infectious and non-infectious complications after transperineal prostate biopsy (TPB) without antibiotic prophylaxis in a multicenter cohort. Secondly, to identify whether increasing the number of cores was predictive for the occurrence of complications. Thirdly, to examine the relation between TPB and erectile dysfunction. METHODS We analyzed a retrospective multicenter cohort of 550 patients from three different urological centers undergoing TPB without antibiotic prophylaxis. The median number of cores was 26. Demographic and clinical data were extracted by reviewing patients' electronic medical records and follow-up data such as postoperative complications obtained by structured phone interviews. To investigate the influence of the number of cores taken on the occurrence of complications, we performed univariate and multivariate mixed effects logistic regression models. RESULTS There was no case of sepsis reported. Overall, 6.0% of patients (33/550) presented with any complication besides mild macrohematuria. In all, 46/47 (98%) complications were ≤Grade 2 according to Clavien-Dindo. In multivariate regression analyses, an increased number of cores was associated with overall complications (odds ratio (OR) 1.08, 95% confidence interval (CI) 1.02-1.14, P = 0.01) and specifically bleeding complications (OR 1.28, 95% CI 1.11-1.50, P = 0.01) but not with infectious complications (OR 1.03, 95% CI 0.97-1.10, P = 0.67). A total of 14.4% of patients referred impairment of erectile function after TPB. Of note, 98% of these men were diagnosed with prostate cancer. CONCLUSIONS This is the first multicenter trial to investigate complications after TPB without antibiotic prophylaxis. In our study, we found no case of sepsis. This underlines the safety advantage of TPB even without antibiotic prophylaxis and supports the ongoing initiative to abandon TRB of the prostate. A higher number of cores were associated with an increase in overall complications specifically bleeding complications, but not with infectious complications. Post-biopsy erectile dysfunction was mainly present in patients diagnosed with PCa.

The molecular mechanisms of fluoroquinolone resistance found in rectal swab isolates of Enterobacterales from men undergoing a transrectal prostate biopsy: the rationale for targeted prophylaxis. Ann Clin Microbiol Antimicrob 2021; 20:81.

Abstract
Background Transrectal ultrasound-guided prostate biopsy (TRUS-Bx) is considered an essential urological procedure for the histological diagnosis of prostate cancer. It is, however, considered a “contaminated” procedure which may lead to infectious complications. Recent studies suggest a significant share of fluoroquinolone-resistant rectal flora in post-biopsy infections. Methods The molecular mechanisms of fluoroquinolone resistance, including PMQR (plasmid-mediated quinolone resistance) as well as mutation in the QRDRs (quinolone-resistance determining regions) of gyrA, gyrB, parC and parE, among Enterobacterales isolated from 32 of 48 men undergoing a prostate biopsy between November 2015 and April 2016 were investigated. Before the TRUS-Bx procedure, all the patients received an oral antibiotic containing fluoroquinolones. Results In total, 41 Enterobacterales isolates were obtained from rectal swabs. The MIC of ciprofloxacin and the presence of common PMQR determinants were investigated in all the isolates. Nine (21.9%) isolates carried PMQR with qnrS as the only PMQR agent detected. DNA sequencing of the QRDRs in 18 Enterobacterales (E. coli n = 17 and E. cloacae n = 1) isolates with ciprofloxacin MIC ≥ 0.25 mg/l were performed. Substitutions in the following codons were found: GyrA—83 [Ser → Leu, Phe] and 87 [Asp → Asn]; GyrB codon—605 [Met → Leu], ParC codons—80 [Ser → Ile, Arg] and 84 [Glu → Gly, Met, Val, Lys], ParE codons—458 [Ser → Ala], 461 [Glu → Ala] and 512 [Ala → Thr]. Six isolates with ciprofloxacin MIC ≥ 2 mg/l had at least one mutation in GyrA together with qnrS. Conclusions This study provides information on the common presence of PMQRs among Enterobacterales isolates with ciprofloxacin MIC ≥ 0.25 mg/l, obtained from men undergoing TRUS-Bx. This fact may partially explain why some men develop post-TRUS-Bx infections despite ciprofloxacin prophylaxis.

Abstract
Introduction and objectives This study aimed to assess the incidence of urinary tract infections (UTIs) after transperineal prostate biopsy (TP-PB) comparing patients who underwent antibiotic prophylaxis (AP) with patients who had no prophylaxis. Materials and methods This prospective, double-center trial was conducted between August and December 2020. Patient candidates to PB were included with 1:1 allocation to case (Group A-no AP) and control group (Group B-standard AP). All TP-PBs were performed in an outpatient setting under local anesthesia. Data collected 2 weeks after the procedure included incidence of UTIs or bacteriuria, evaluated with a urine culture (UC), main symptoms, and complications related to TP-PBs. Results A total of 200 patients were included (100 patients in each group). The mean age was 66.2 ± 7.7 in Group A and 67.4 ± 8 years in Group B (P = 0.134). Mean prostate volume was 65.5 ± 26.7 vs. 51 ± 24.6 cc (P < 0.001), number of biopsy cores was 17.8 ± 2.4 vs. 14.9 ± 0.8 (P < 0.001), and PSA value was 15.9 ± 28.1 vs. 13.3 ± 22.3 ng/ml (P = 0.017). Overall PCa detection rate was 55% vs. 59% (P = 0.567). Postoperative UTI occurred in one patient in Group A vs. zero in Group B. Asymptomatic bacteriuria was present in 3 vs. 5 patients (P = 0.470) and was not treated with antibiotics. Postoperative hematuria was observed in 13 patients vs. 29 (P < 0.05), and acute urinary retention was observed in one patient in each group. Conclusions The incidence of bacteriuria and UTIs in TP-PBs is not related to AP. Therefore, AP could be discontinued in TP-PB candidates without the risk of increasing UTI-related complications.

Abstract
Infection is the second leading cause of death in patients with cancer. Loss of efficacy in antibiotics due to antibiotic resistance in bacteria is an urgent threat against the continuing success of cancer therapy. In this review, the authors focus on recent updates on the impact of antibiotic resistance in the cancer setting, particularly on the ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp.). This review highlights the health and financial impact of antibiotic resistance in patients with cancer. Furthermore, the authors recommend measures to control the emergence of antibiotic resistance, highlighting the risk factors associated with cancer care. A lack of data in the etiology of infections, specifically in oncology patients in United States, is identified as a concern, and the authors advocate for a centralized and specialized surveillance system for patients with cancer to predict and prevent the emergence of antibiotic resistance. Finding better ways to predict, prevent, and treat antibiotic-resistant infections will have a major positive impact on the care of those with cancer.

Abstract
PURPOSE Worldwide, transrectal ultrasound-guided prostate needle remains the most common method of diagnosing prostate cancer. Due to high infective complications reported, some have suggested it is now time to abandon this technique in preference of a trans-perineal approach. The aim of this study was to report on the infection rates following transrectal ultrasound-guided prostate needle biopsy in multiple Australian centres. MATERIALS AND METHODS Data were collected from seven Australian centres across four states and territories that undertake transrectal ultrasound-guided prostate needle biopsies for the diagnosis of prostate cancer, including major metropolitan and regional centres. In four centres, the data were collected prospectively. Rates of readmissions due to infection, urosepsis resulting in intensive care admission and mortality were recorded. RESULTS 12,240 prostate biopsies were performed in seven Australian centres between July 1998 and December 2020. There were 105 readmissions for infective complications with rates between centres ranging from 0.19 to 2.60% and an overall rate of 0.86%. Admission to intensive care with sepsis ranged from 0 to 0.23% and overall 0.03%. There was no mortality in the 12,240 cases. CONCLUSION Infective complications following transrectal ultrasound-guided prostate needle biopsies are very low, occurring in less than 1% of 12,240 biopsies. Though this study included a combination of both prospective and retrospective data and did not offer a comparison with a trans-perineal approach, TRUS prostate biopsy is a safe means of obtaining a prostate cancer diagnosis. Further prospective studies directly comparing the techniques are required prior to abandoning TRUS based upon infectious complications.

Abstract
Background The ability to discriminate indolent from clinically significant prostate cancer (PC) at the initial biopsy remains a challenge. The ExoDx Prostate (IntelliScore) (EPI) test is a noninvasive liquid biopsy that quantifies three RNA targets in urine exosomes. The EPI test stratifies patients for risk of high-grade prostate cancer (HGPC; ≥ Grade Group 2 [GG] PC) in men ≥ 50 years with equivocal prostate-specific antigen (PSA) (2–10 ng/mL). Here, we present a pooled meta-analysis from three independent prospective-validation studies in men presenting for initial biopsy decision. Methods Pooled data from two prospective multi-site validation studies and the control arm of a clinical utility study were analyzed. Performance was evaluated using the area under the receiver-operating characteristic curve (AUC), negative predictive value (NPV), positive predictive value (PPV), sensitivity, and specificity for discriminating ≥ GG2 from GG1 and benign pathology. Results The combined cohort (n = 1212) of initial-biopsy subjects had a median age of 63 years and median PSA of 5.2 ng/mL. The EPI AUC (0.70) was superior to PSA (0.56), Prostate Cancer Prevention Trial Risk Calculator (PCPT-RC) (0.62), and The European Randomized Study of Screening for Prostate Cancer (ERSPC) (0.59), (all p-values <0.001) for discriminating GG2 from GG1 and benign histology. The validated cutoff of 15.6 would avoid 23% of all prostate biopsies and 30% of “unnecessary” (benign or Gleason 6/GG1) biopsies, with an NPV of 90%. Conclusions EPI is a noninvasive, easy-to-use, urine exosome–RNA assay that has been validated across 3 independent prospective multicenter clinical trials with 1212 subjects. The test can discriminate high-grade (≥GG2) from low-grade (GG1) cancer and benign disease. EPI effectively guides the biopsy-decision process independent of PSA and other standard-of-care factors.

Abstract
OBJECTIVE The aim of this study was to compare diagnostic and infectious outcomes between MRI-guided transrectal (TR) and transperineal (TP) prostate biopsies, in order to evaluate implementation of local-anaesthesia TP biopsies in a Swedish university hospital setting. METHODS In this non-randomized observational study, we recruited 105 patients who underwent TR or TP software-based MRI-ultrasound fusion prostate biopsies between April and August 2020. Information on outcome and covariates were obtained from hospital records. We compared detection rates of overall prostate cancer (PCa) and clinically significant PCa (≥ISUP2) between the two groups using simple and multivariable-adjusted analyses. As a secondary outcome, we descriptively compared infection-related outcomes between the two groups. RESULTS Of the total population, 72 patients underwent TR and 33 patients underwent TP biopsies. Biopsies were positive for PCa in 50 (69.4%) patients of the TR group and 23 (69.7%) patients of the TP group. Clinically significant cancer was found in 28 (38.9%) patients of the TR group and 10 (30.3%) patients of the TP group. Simple and multivariable-adjusted analyses did not indicate any statistically significant difference between groups. Post-biopsy infection was diagnosed in one patient (3%) of the TP group and eight patients (11.1%) in the TR group, conforming to previous reports of low infection rates after TP biopsies. CONCLUSIONS Our results conform to data suggesting that the transition from TR to TP MRI-guided biopsies is feasible and safe, maintaining a high diagnostic quality while possibly reducing the risk of infection-related complications.

Changing the Prostate Cancer Detection Paradigm: Clinical Application of European Association of Urology Guideline-recommended Magnetic Resonance Imaging-based Risk Stratification in Men with Suspected Prostate Cancer. Eur Urol Focus 2021; 7:1011-1018. [PMID: 33036953 DOI: 10.1016/j.euf.2020.09.014] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2020] [Revised: 09/02/2020] [Accepted: 09/22/2020] [Indexed: 12/31/2022]
Abstract
BACKGROUND Multiparametric magnetic resonance imaging using the Prostate Imaging Reporting and Data System version 2.1 allows for a personalized, risk-stratified approach to indicating prostate biopsies (PBx) in order to reduce PBx and concomitant complications in men with suspected prostate cancer (PCa). One way to achieve this goal is to implement the risk-stratified pathway (RSP) using the Rotterdam Prostate Cancer Risk Calculator. OBJECTIVE To describe the clinical implementation of the RSP and to examine its impact on the number of PBx and the resulting changes in the PCa detection pattern compared with men undergoing PBx in a detection-focused pathway (DFP) without prior risk assessment. DESIGN, SETTING, AND PARTICIPANTS An institutional dataset of 505 consecutive patients with suspected PCa between July 2019 and February 2020 was used. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Chi-square test and Mann-Whitney U test were employed to examine differences in the number of PBx and the PCa detection pattern between the DFP (n = 195, 38.6%) and the RSP (n = 310, 61.4%). To minimize differences in risk stratification, inverse probability of treatment weighting was used. RESULTS AND LIMITATIONS After implementing the RSP, the overall biopsy rate could be reduced by 11.2% (100% vs 88.8%, p < 0.001. Additionally, compared with the DFP, the number of biopsy cores per patient was reduced in the RSP (14 [interquartile range {IQR} 14-15] vs 14 [IQR 6-14], p < 0.001) and the detection of clinically significant PCa was increased (44.3% vs 57.7%, p = 0.038). Overdiagnosis of clinically insignificant disease was decreased in the RSP (22.8% vs 12.6%, p = 0.039). CONCLUSIONS Implementation of the RSP in clinical practice reduced the number of PBx and brought forth a shift in the PCa detection pattern toward clinically significant disease, while reducing overdiagnosis of clinically insignificant disease. PATIENT SUMMARY In this study, we examined the impact of risk stratification on the number of prostate biopsies (PBx) and the consecutive detection pattern in men with suspected prostate cancer (PCa). We found that the risk-stratified pathway reduced the number of PBx while simultaneously shifting the PCa detection pattern toward clinically significant PCa.

Rationale and protocol for randomized study of transrectal and transperineal prostate biopsy efficacy and complications (ProBE-PC study). Prostate Cancer Prostatic Dis 2021; 24:688-696. [PMID: 33767354 DOI: 10.1038/s41391-021-00352-1] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2020] [Revised: 02/21/2021] [Accepted: 03/08/2021] [Indexed: 02/01/2023]
Abstract
BACKGROUND Rrisk of infection and hospitalization after transrectal prostate biopsy (TRBx) has been increasing worldwide. Several modified antibiotic regimens have met with variable success in preventing such infections. Transperineal prostate biopsy (TPBx) is increasingly recommended as the preferred alternative due to a potentially lower risk of post-biopsy infections. Aim of this review is to define the magnitude of post-biopsy complications and the effectiveness of preventive strategies, including TPBx approach. METHODS We performed a focused review of literature on infectious complications after TRBx and detailed the use of various preventive measures. We summarized the effectiveness of several preventive measures, including TPBx, and outlined the inconsistencies in reported outcomes. We identified potential barriers to the uptake of TPBx, including the gap in knowledge such as lack of high-quality evidence. RESULTS Several antibiotic prophylaxis protocols, including targeted and augmented, have been utilized for TRBx without demonstrating a clearly superior regimen. Of the non-antibiotic preventive measure, povidone-iodine rectal prep appears to be most effective strategy. Several single-arm cohort studies have reported very low rates of infections after TPBx and demonstrated the feasibility of an office-based procedure. However, barriers to the adoption of TPBx exist including retrospective data, and conflicting results showing minimal reduction in complications with increased burden of resource utilization. Presently, there are no randomized studies comparing the infectious complications after TRBx and TPBx. We discuss the rationale and protocol for a randomized controlled trial to determine the comparative effectiveness of biopsy techniques. CONCLUSIONS TPBx approach has the potential to lower the rate of post-biopsy infections and hospitalizations. However, there are several barriers to widespread adoption of this approach including inconsistencies in reported outcomes and lack of Level-1 evidence. Randomized controlled studies are required to directly compare the infectious complications associated with each biopsy procedure.

Abstract
OBJECTIVE To externally validate and compare the performance of the European Randomized Study of Screening for Prostate Cancer risk calculator 3/4 (ERSPC-RC3/4), the Prostate Biopsy Collaborative Group risk calculator (PBCG-RC) and the van Leeuwen model to determine which prediction model would perform the best in a contemporary Australian cohort undergoing transperineal (TP) biopsy. MATERIALS AND METHODS A retrospective review identified all patients undergoing TP biopsy across two centres. Of the 797 patients identified, 373 had the data required to test all three risk calculators. The probability of high-grade prostate cancer, defined as International Society of Urological Pathology Grade Group >1, was calculated for each patient. For each prediction model discrimination was assessed using area under the receiver-operating characteristic curve (AUC), calibration using numerical and graphical summaries, and net benefit using decision curve analysis. RESULTS Assessment of model discrimination for detecting high-grade prostate cancer showed AUCs of 0.79 (95% confidence interval [CI] 0.74-0.84) for the ERSPC-RC3/4, 0.81 (95% CI 0.77-0.86) for the van Leeuwen model, and 0.68 (95% CI 0.63-0.74) for the PBCG-RC, compared to 0.58 (95% CI 0.52-0.65) for prostate-specific antigen alone. The ERSPC-RC3/4 was the best calibrated in the moderate-risk range of 10-40%, whilst the van Leeuwen model was the best calibrated in the low-risk range of 0-10%. The van Leeuwen model demonstrated the greatest net benefit from 10% risk onwards, followed closely by the ERSPC-RC3/4 and then the PBCG-RC. CONCLUSION The ERPSC-RC3/4 demonstrated good performance and was comparable to the van Leeuwen model with regard to discrimination, calibration and net benefit for an Australian population undergoing TP prostate biopsy. It is one of the most accessible risk calculators with an easy-to-use online platform, therefore, we recommend that Australian urologists use the ERSPC-RC3/4 to predict risk in the clinical setting.

Abstract
OBJECTIVES The aim of this study was to assess the incidence of infection after transrectal prostate biopsy (TRbx). Secondary objectives were to describe infection characteristics, antibiotic resistance patterns, ICD-10 coding, and costs. METHODS TRbx carried out at the hospitals of Ängelholm and Helsingborg, Scania, Sweden, between October 2017 and March 2019, were identified based on the NOMESCO Classification of Surgical Procedures code for TRbx, TKE00. All patients received per oral antibiotic prophylaxis, usually 750 mg ciprofloxacin at biopsy. Other preventative measures were not used. Medical care within 30 days of the biopsy was evaluated through a manual retrospective medical chart review. Data on patient and infection characteristics were collected. The costs of infections causing hospitalization were estimated. RESULTS After 36 (5.4%) of 670 biopsies, the patient developed post-biopsy infection within 30 days after TRbx. Twenty-six patients (3.9%) required hospitalization for an average of 6 days, at an estimated direct cost of USD 9174 (EUR 8031) per patient. Nine patients (1.3%) had a complicated infection leading to intensive care, multiple hospitalizations or emergency department visits. The inpatient care episodes for the 26 hospitalized patients were categorized with 15 different ICD-codes. In 6 episodes no ICD-code related to infection was used. CONCLUSIONS In this study, we found an infection rate of 5.4% after TRbx; 3.9% of the patients were hospitalized for a post-TRbx infection and 1.3% had complicated infections. A specific ICD code for post-TRbx infections would facilitate evaluation and monitoring of this common, costly, and sometimes serious complication.

Abstract
BACKGROUND Transrectal prostate biopsy (TRbx) transfers colonic bacteria into prostatic tissue, potentially causing infectious complications, including sepsis. Our objective was to determine whether biopsy needle shape, surface properties and sampling mechanism affect the number of bacteria transferred through the colon wall, and evaluate a novel needle with improved properties. METHODS The standard Tru-Cut biopsy needle used today was evaluated for mechanisms of bacterial transfer in a pilot study. A novel Tru-Cut needle (Forsvall needle prototype) was developed. TRbx was simulated using human colons ex-vivo. Four subtypes of the prototype needle were compared with a standard Tru-Cut needle (BARD 18 G). Prototype and standard needles were used to puncture 4 different colon specimens in 10 randomized sites per colon. Needles were submerged into culture media to capture translocated bacteria. The media was cultured on blood agar and then the total amount of transferred bacteria was calculated for each needle. The primary outcome measure was the percent reduction of bacteria translocated by the prototype needles relative to the standard needle. Secondary outcome measures were the effects of tip design and coating on the percent reduction of translocated bacteria. RESULTS Prototype needles reduced the number of translocated bacteria by, on average, 96.0% (95% confidence interval 93.0-97.7%; p < 0.001) relative to the standard needle. This percent reduction was not significantly affected by prototype needle tip style or surface coating. CONCLUSIONS The Forsvall needle significantly reduces colonic bacterial translocation, suggesting that it could reduce infectious complications in prostate biopsy. A clinical trial has been initiated.

Abstract
BACKGROUND Transrectal prostate biopsy (TRbx) carries an increasing risk of infection. The Forsvall Needle Prototype (FNP) is a novel biopsy needle that reduces bacterial load brought across the rectum and may therefore reduce infection risk. The objective of this study was to compare biopsy length, quality and patient experience for the FNP Version 2 (FNP2) versus a standard Tru-Cut needle. METHODS We conducted a randomized, parallel-group, non-inferiority trial with twenty consecutive patients eligible for TRbx. Participants were randomized to undergo TRbx using either FNP2 or a standard Tru-Cut needle. The primary outcome was difference in mean biopsy lengths measured by the pathologist. FNP2 biopsy lengths ≤1.35 mm of the standard needle length were considered non-inferior. Secondary outcomes were biopsy length in the needle chamber and immediately after removal, biopsy quality, biopsy fragmentation, patient discomfort/pain, and complications (immediate and after 14 and 30 days). RESULTS Mean pathologist-measured FNP2 biopsy length was non-inferior compared to the standard Tru-Cut needle (0.02 mm longer, 95%CI-0.73 to 0.76 mm). Biopsy length in the needle chamber and immediately after removal were also non-inferior. Biopsy quality and patient discomfort were not significantly different for the FNP2 and the standard Tru-Cut needle. Biopsy fragmentation was more common in the FNP2 group. CONCLUSIONS The FNP2 biopsy needle is non-inferior to the Tru-Cut needle in terms of biopsy length and not significantly different in terms of biopsy quality and patient experience. Future studies will evaluate the Forsvall needle design's effect on post-biopsy infection risk.

Abstract
Objectives: This study aimed to describe a UK institution’s experience with local anaesthetic (LA) transperineal (TP) prostate biopsies (PB), and to report 30-day complications following LATPPB, including a large cohort that did not receive antibiotic prophylaxis. Patients and methods: A prospective database of 313 consecutive patients undergoing LATPPB was maintained, describing patient and disease characteristics, and complications. From September 2019 to January 2020, antibiotic prophylaxis was given before LATPPB ( n=149). Following a change to routine care, from January 2020 to July 2020, prophylactic antibiotics were not given before LATPPB ( n=164). A comparative analysis was performed to determine complication rates following antibiotic prophylaxis discontinuation using electronic hospital and primary care records. Results: Patient and disease characteristics were comparable in antibiotic and non-antibiotic cohorts, and representative of PB and prostate cancer cohorts described in the urological literature. The infection-related complication rate was 0.32% across all patients, and 0% for those not receiving antibiotic prophylaxis. The overall complication rate was 0.64%, and 0.61% for those not receiving antibiotic prophylaxis. There were no severe (Clavien–Dindo 3–5) complications. The unplanned hospital admission rate was 0.64%. Conclusion: The complication rate after LATPPB was low, with no infection-related complications in patients who did not receive antibiotic prophylaxis. This provides further evidence supporting the discontinuation of routine prophylactic antibiotics before TPPB. Level of evidence: Level 2b.

Abstract
STUDY AIMS To investigate safety and side effects of transperineal prostate biopsy without antibiotic prophylaxis. Secondary aim was to identify whether the number of cores influenced the occurrence of complications. PATIENTS AND METHODS A cohort of 184 patients undergoing perineal prostate biopsy without antibiotic prophylaxis from 2015 to 2017 was analyzed retrospectively. On average, 41 cores were taken via two perineal skin punctures. Demographic and clinical data were obtained from patients´ electronic medical records. Binary logistic regression was performed to identify predictors for complications with the following covariates: age, prostate specific antigen (PSA), prostate volume, Prostate Imaging Reporting and Data System score, history of prostatitis, therapeutic anticoagulation, risk factors for urinary tract infection, surgery duration, and the number of biopsy cores. Furthermore, we calculated chi-squared tests with post hoc analyses for differences in the occurrence of complications between quartiles of the above-mentioned parameters. RESULTS The overall complication rate was 10.8% (20/185). Out of 20, 19 (95 %) complications were ≤ grade 2 according to the Clavien-Dindo classification. There were two cases of afebrile urinary tract infection, and no patient developed fever or sepsis. Acute urinary retention was reported in 10 patients (5.4 %). The total number of cores was not associated to infectious complications or acute urinary retention rates. CONCLUSIONS Transperineal prostate biopsy without antibiotic prophylaxis is a safe procedure. Neither postoperative fever nor sepsis occurred. An increased number of cores through two skin punctures was not associated with more complications.

Abstract
Transperineal biopsy is becoming more commonly used, driven by improved detection rates, better complication profile and increasing application of prostate MRI leading to guided biopsy. However, it can still lead to complications such as urinary retention, postoperative pain and erectile dysfunction. There is also a potential for adverse events such as severe infection, abscess and fistula. This article describes a case of an intrascrotal abscess post-transperineal biopsy, which required an orchidectomy.

Abstract
Background: The recent plethora of reports of "free-hand" transperineal prostate biopsy (fTP-Bx) under local anesthesia (LA) demonstrate that many centers consider this technique to be a safer and possibly more accurate approach to prostate biopsy in the clinic setting. Materials and Methods: The literature was searched for fTP-Bx, and summary tables were compiled. Studies on the costs of postprostate biopsy sepsis were also researched. Results: The search found 11,999 cases of fTP-Bx under LA with and without sedation over 29 mutually exclusive studies. Pooled averages calculated for age, prostate-specific antigen (PSA), prostate volume, PSA density, and cores sampled were 67.3 years, 10.4 ng/mL, 47.7 mL, 0.24 ng/mL/cc, and 15.3 cores, respectively. Detection of overall prostate cancer (PCa) and clinically significant (Gleason score ≥7) prostate cancer (csPCa) averaged 45.5% (3796/8338) and 25.1% (1141/4541), respectively. After subgrouping the studies by biopsy technique, studies that used MRI/ultrasound fusion-targeted biopsy in some or all biopsy cases averaged an overall PCa and csPCa detection rate of 50.0% (741/1483) (p < 0.0001) and 42.8% (635/1483) (p < 0.0001), respectively. Visual analog scale pain ratings and procedure times averaged 3.17 and 13.1 minutes, respectively. Averages for complications of sepsis and acute urinary retention were 0.0% (0/7396) and 2.1% (120/5693), respectively. A total of 10.2% (1055/10,334) of cases received no antibiotic prophylaxis. If fTP-Bx under LA replaced transrectal prostate biopsy (TR-Bx) in the United States, the estimated annual savings would be $341,676,800-$752,540,000 through the virtual elimination of admissions for postbiopsy sepsis. Conclusions: Many centers around the world have adopted fTP-Bx because it virtually eliminates sepsis, may improve detection rates of csPCa and can be easily integrated into a normal clinic workflow using only LA. If all urologists in the United States abandoned TR-Bx for fTP-Bx, the potential savings in health care costs of complications would be significant.

Abstract
BACKGROUND Transrectal (TR) and transperineal (TP) approaches for prostate biopsy have different morbidity profiles. Our institution transitioned to a preference for multiparametric MRI-based triage and TP biopsy since 2014. The aim of this study was to compare clinical, microbiological and health economic outcomes between TR and TP prostate biopsy. METHODS A consecutive cohort study considered prostate biopsies over an 11 year period. Hospital presentations across the region within 30 days of biopsy were analysed for details and subsequent outcomes according to biopsy approach. Cost for each encounter (routine and unplanned) were analysed and generalised linear models applied, as well as cost implications for inclusion of mpMRI-based triage and TP biopsy preference. RESULTS In total, 2048 prostate biopsies were performed. Similar re-presentation rates per occurred for each biopsy approach (90 patients, TR 4.8%, TP 3.8%, p = 0.29), with 23 patients presenting more than once (119 total presentations). Presentations after TR biopsy were more likely to be of infectious aetiology (TR 2.92%, TP 0.26% de novo, p < 0.001) and result in hospital admission (TR 43/49, 93.4%; TP 14/24, 58.3%; p = 0.007) for similar rates of urinary retention (TR 2.76% vs TP 3.63%, p = 1). The mean overall cost (biopsy and re-presentations) was higher for the TP group (p < 0.001), adjusted for year and age, but reduced over time and was similar for patients who re-presented (p = 0.98). Incorporation of mpMRI (with subsequently avoided biopsies), TP biopsy and re-presentations resulted in AU$783.27 saving per biopsy. CONCLUSIONS TR biopsy resulted in more infectious complications and hospital admissions than TP biopsy for similar rates of re-presentation and urinary retention. TP biopsy costs reduced over time and use in conjunction with mpMRI provides an overall cost saving. Routine TP biopsy is safe and feasible, with further cost savings expected with other approaches (local anaesthetic) under investigation.

Multicentre clinical evaluation of the safety and performance of a simple transperineal access system for prostate biopsies for suspected prostate cancer: The CAMbridge PROstate Biopsy DevicE (CamPROBE) study. JOURNAL OF CLINICAL UROLOGY 2020; 13:364-370. [PMID: 33072331 PMCID: PMC7521793 DOI: 10.1177/2051415820932773] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2020] [Accepted: 05/16/2020] [Indexed: 01/26/2023]
Abstract
Objectives: To report the prospective multicentre clinical evaluation of a first-in-man disposable device, Cambridge Prostate Biopsy Device, to undertake local anaesthetic outpatient transperineal prostate biopsies. Material and methods: Disposable single-use Cambridge Prostate Biopsy devices were manufactured based on a previous prototype. The lead site developed a user training course and disseminated the method to other sites. The Cambridge Prostate Biopsy Device (CamPROBE) was offered as an alternative to transrectal ultrasound guided biopsy to men due for a biopsy as part of their clinical management. Data on safety (infections and device performance), clinical utility, patient reported experience, biopsy quality and cancer detection were collected. Procedure time and local anaesthetic use was recorded in the lead site. The study was funded by a United Kingdom National Institute for Health Research (NIHR) i4i product development award. Results: A total of 40 patients were recruited (median age 69 y) across six sites; five sites were new to the procedure. Overall, 19/40 were first prostate biopsies and 21/40 repeat procedures. Both image-targeted and systematic biopsy cores taken. There were no infections, device deficiencies or safety issues reported. The procedure was well tolerated with excellent patient-reported perception and low pain scores (median of 3, scale 0–10). Histopathology quality was good and the overall cancer diagnosis rate (first diagnostic procedures) was 68% (13/19) and for significant cancers (⩾ histological Grade Group 2), 47% (9/19). In the lead centre (most experienced), median procedure time was 25 minutes, and median local anaesthetic use 11 ml (n=17). Conclusions: Data from this device evaluation study demonstrate that the United Kingdom-developed Cambridge Prostate Biopsy Device/method for transperineal biopsies is safe, transferable and maintains high diagnostic yields. The procedure is well tolerated by patients, suited to the local anaesthetic outpatient setting and could directly replace transrectal ultrasound guided biopsy. Level of evidence: Level III

Infectious complications of prostate biopsy: winning battles but not war. World J Urol 2020; 38:2743-2753. [PMID: 32095882 DOI: 10.1007/s00345-020-03112-3] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2019] [Accepted: 01/30/2020] [Indexed: 12/27/2022] Open
Abstract
BACKGROUND Prostate biopsy is a standard tool for diagnosing prostate cancer, with more than 4 million procedures performed worldwide each year. Infectious complications and economic burden are reportedly rising with continued use of trans-rectal ultrasound-guided biopsy, despite the transperineal approach being associated with less infectious complications. OBJECTIVE AND METHODS In this review, the contemporary literature on pathophysiology, epidemiology, risk factors, causative organisms and emerging approaches for prevention of infectious complications are outlined. RESULTS Management of infectious complications after TRUSB has caused significant financial burden on health systems. The most frequent causative agents of infectious complications after prostate biopsy are Gram-negative bacilli are particularly concerning in the era of antibiotic resistance. Increasing resistance to fluoroquinolones and beta-lactam antibiotics has complicated traditional preventive measures. Patient- and procedure-related risk factors, reported by individual studies, can contribute to infectious complications after prostate biopsy. CONCLUSIONS Recent literature shows that the transrectal ultrasound-guided prostate biopsy results in higher infectious complication rate than the transperineal prostate biopsy. NAATs, recently introduced technique to detect FQr may detect all antibiotic-resistant rectal microbiota members-included MDRs-although the technique still has limitations and economical burdens. Transient solutions are escalating antibiotic prophylaxis and widening the indications for TPB.
