Objectives: To prospectively evaluate the efficacy of single dose antibiotic prophylaxis in 12‐core transrectal ultrasonography (TRUS) guided prostate biopsy. Methods: A total of 400 patients who underwent prostate biopsy with TRUS guidance were included. The patients were prospectively randomized in three groups regarding antibiotic prophylaxis. The first group (139 patients) received a single gram of intramuscular ceftriaxone, while the second group (131 patients) had a 3‐day course of oral ciprofloxacin. The third group (130 patients) had single oral 500 mg of ciprofloxacin. All patients had urine cultures prior to biopsy and on the second day after biopsy. Results: The study groups were compared in terms of the results of urine cultures and clinical parameters. Overall, only seven patients (1.8% of the cases) had positive urine cultures with no difference between these three groups. Additionally, no significant difference was observed regarding morbidity rates in all groups. Only eight patients (2%) developed major complications requiring hospitalization. There was no increase in the rate of infectious complications when the biopsy core numbers were increased up to 12. Conclusions: The current study suggests that a single oral dose of antimicrobial prophylaxis is reasonable in TRUS prostate biopsy even in the case of 12‐core sampling. 相似文献

Study Type – Diagnostic (exploratory cohort) Level of Evidence 2b What's known on the subject? and What does the study add? Template assisted transperineal biopsy of the prostate has become increasingly popular over the past decade. Several studies have demonstrated that transperineal prostate biopsy (TPB) is associated with an increased rate of cancer detection, increased histological concordance with final prostatectomy samples and an increase in anterior and apical prostate cancers than standard TRUS biopsy. However, interpretation of the literature is difficult due to considerable variation between studies in terms of technique and equipment. We examined a small cohort (n= 40) of patients using a standardized 36 core template assisted TPB technique. We show that utilising this technique is associated with high cancer (68%) detection rate in patients with two previous negative TRUS biopsies. Of patients were found to have anterior gland tumours which would not have been detected by standard TRUS guided biopsy.
OBJECTIVE
? To determine the efficacy and safety of a standardized 36 core template‐assisted transperineal biopsy technique for detecting prostate cancer in patients with previously negative transrectal ultrasonography‐guided prostate biopsies and elevated prostate‐specific antigen (PSA) levels.PATIENTS AND METHODS
? Between April 2008 to September 2010, a total of 40 patients with a mean (range) age of 63 (49–73) years, a mean (range) elevated PSA level of 21.9 (4.7–87) ng/mL and two previous sets of negative TRUS‐guided prostate biopsies underwent standardized 36 core template‐assisted transperineal prostate biopsies under general anaesthetic as a day case procedure. ? The cancer detection rate and complications for all cases were evaluated.RESULTS
? In total, 27 of 40 (68%) patients were found to have adenocarcinoma of the prostate, two patients (5.0%) had atypical small acinar proliferation, one had high‐grade prostatic intraepithelial neoplasia (2.5%), four (10%) had chronic active inflammation and six (15%) had benign histology. ? Gleason scores were in the range 6–9, with a median Gleason score of 7. ? There were no cases of urosepsis, urinary tract infections or haematuria. A single patient experienced acute urinary retention, with a subsequent succesful trial without a catheter, and haematospermia was common, although minor.CONCLUSIONS
? Our standardized 36 core template‐assisted transperineal prostate biopsy technique is safe and associated with a high detection rate of prostate cancer. ? This technique should be considered in patients with elevated PSA levels and previously negative TRUS‐guided prostate biopsies. 相似文献6.

OBJECTIVE
To compare the incidence of infective events between a single dose and 3‐day antibiotic prophylaxis for transrectal ultrasonography (TRUS)‐guided prostate biopsy.PATIENTS AND METHODS
Patients were randomized to receive either one preoperative dose consisting of two ciprofloxacin 500 mg tablets 2 h before prostate biopsy, or 3 days of ciprofloxacin treatment. They had a clinical examination at study inclusion, the day of the biopsy and 3 weeks later. The day after the procedure all patients were contacted by telephone to inquire about any significant event. Biological testing and urine cultures were conducted 5 days before and then 5 and 15 days after the biopsy; a self‐administered symptom questionnaire was completed by the patient 5 days before and then at 5 and 15 days.RESULTS
The study group included 288 men, of whom 139 were randomized to the single‐dose arm and 149 to the 3‐day arm. Six patients in each group had an asymptomatic bacteriuria with no leukocyturia. One patient in each group had documented prostatitis, with Escherichia coli identified on urine culture. The strain identified in the patient from the 3‐day group was resistant to ciprofloxacin. There was no difference between groups in symptoms at 5 and 21 days after biopsy.CONCLUSIONS
Current TRUS‐guided prostate biopsy techniques lead to very few clinical infectious complications when accompanied by antibiotic prophylaxis. We found no argument to advocate the use of more than one dose of antibiotic prophylaxis. 相似文献8.

This systematic review was performed to compare the efficacy and complications of transperineal (TP) vs. transrectal (TR) prostate biopsy. A systematic research of PUBMED, EMBASE and the Cochrane Library was performed to identify all clinical controlled trials on prostate cancer (PCa) detection rate and complications achieved by TP and TR biopsies. Prostate biopsies included sextant, extensive and saturation biopsy procedures. All patients were assigned to a TR group and a TP group. Subgroup analysis was performed according to prostate-specific antigen (PSA) levels and digital rectal examination (DRE) findings. The Cochrane Collaboration's RevMan 5.1 software was used for the meta-analysis. A total of seven trials, including three randomized controlled trials (RCTs) and four case-control studies (CCS), met our inclusion criteria. There was no significant difference in the cancer detection rate between the sextant TR and TP groups (risk difference (RD), -0.02; 95% confidence interval (CI), -0.08-0.03; P=0.34). Meta-analysis for RCTs combined with CCS showed that there was no difference in the cancer detection rate between the extensive TR and TP group (RD, -0.01; 95% CI, -0.05-0.04; P=0.81). There was no significant difference in PCa detection rate between the saturation TR and TP approaches (31.4% vs. 25.7%, respectively; P=0.3). There were also no significant differences in cancer detection between the TR and TP groups in each subgroup. Although the data on complications were not pooled for the meta-analysis, no significant difference was found when comparing TR and TP studies. TR and TP biopsies were equivalent in terms of efficiency and related complications. TP prostate biopsy should be an available and alternative procedure for use by urologists. 相似文献

To compare the incidence of infective complications after transrectal ultrasonography (TRUS)‐guided biopsy with either empirical fluoroquinolone or culture‐based targeted antimicrobial prophylaxis, and the prevalence of fluoroquinolone resistance (FQ‐R) in men undergoing prostate biopsy. A systematic review of the literature was performed following Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines. We included studies of patients undergoing TRUS‐guided biopsy that compared infective outcomes of those who received targeted antimicrobial therapy based on the results of pre‐procedural rectal swab cultures, with those receiving empiric fluoroquinolone antimicrobial prophylaxis. The prevalence of FQ‐R was recorded as a secondary outcome measure. Studies with no control group were excluded. From 125 studies screened, nine studies (4 571 patients) met the inclusion criteria. All studies were of cohort design, and included a combination of retrospective and prospective data. Six studies included were undertaken in North America. The remaining studies were undertaken in Spain, Turkey and Columbia. Within these studies, 2 484 (54.3%) patients received empirical fluoroquinolone prophylaxis, whilst 2 087 (45.7%) patients had pre‐biopsy rectal swabs and targeted antibiotics. The mean FQ‐R was 22.8%. Post‐biopsy infection and sepsis rates were significantly higher in groups given empirical prophylaxis (4.55% and 2.21%) compared with groups receiving targeted antibiotics (0.72% and 0.48%). Based on these results 27 men would need to receive targeted antibiotics to prevent one infective complication. Our systematic review suggests that targeted prophylactic antimicrobial therapy before TRUS‐guided prostate biopsy is associated with lower rates of sepsis. We therefore recommend changing current pathways to adopt this measure. 相似文献

OBJECTIVE
To evaluate the effect of transperineal template‐guided prostate mapping biopsy (TTMB) on urinary, bowel and erectile function.PATIENTS AND METHODS
In all, 129 men had TTMB; a median of 56 biopsy cores were obtained per patient. Tamsulosin (0.8 mg daily) was initiated 2 days before TTMB and continued for 2 weeks. The International Prostate Symptom Score (IPSS), Rectal Function Assessment Score (R‐FAS), International Index of Erectile Function (IIEF)‐6 and the postvoid residual volume (PVR) were assessed at baseline and after 30 days, except for the IPSS, which was also assessed at 7 days. Several variables were evaluated as predictors of TTMB‐induced morbidity.RESULTS
The mean patient age was 64.7 years with a mean prostate volume of 74.3 mL; 60 men (46.5%) were diagnosed with prostate cancer. After TTMB, 39.4%, 7.1% and 1.6% of patients remained catheter‐dependent at 0, 3 and 6 days. The median catheter‐dependency was 0, 1, 2 and 3 days for prostate volumes of <60, 60–90, 90–120 and >120 mL, respectively. No patient remained catheter‐ dependent for >12 days or required a transurethral resection secondary to TTMB. The mean IPSS before TTMB was 10.4, and was 4.6 and 3.8 at 7 and 30 days. At baseline and 30 days the mean PVR was 35 and 40 mL, and the median R‐FAS and IIEF scores for patients potent before TTMB were 2.0 and 2.2, and 27.0 and 26.0, respectively.CONCLUSIONS
TTMB is a promising procedure for diagnosing prostate cancer. TTMB‐related morbidity differs from that of standard TRUS biopsy primarily in the incidence of temporary urinary retention, and is comparable in terms of urinary, bowel and erectile function. 相似文献15.

AIM: The optimal biopsy strategy for prostate cancer detection, especially in men with isolated prostate-specific antigen (PSA) elevation, remains to be defined. We evaluated diagnostic yield and safety of transrectal ultrasound (TRUS)-guided transperineal systematic 14-core biopsy and compared the spatial distribution of cancer foci detected with this technique in men with and without abnormality on digital rectal examination (DRE). METHODS: In a prospective study, 289 men aged between 50 and 87 years (median age, 70 years) underwent TRUS-guided transperineal systematic 14-core prostate biopsy because of elevated PSA and/or abnormal DRE findings. Using the fan technique, 12 cores from the peripheral zone and two cores from the transition zone were obtained systematically. To characterize the spatial distribution of cancer positive cores, site-specific overall and unique cancer detection rates were compared between stage T1c and T2 cancers. RESULTS: Prostate cancer was detected in 105 of the 289 patients (36%). Major complications requiring prolonged hospital stay or re-hospitalization during a 4-week postbiopsy period were rare (1.4%). Sixty-seven stage T1c cancers were identified. These cancers were associated with significantly lower PSA and a smaller number of cancer positive cores when compared with stage T2 cancers (n= 38). The overall cancer detection rate was highest at the anterior peripheral zone and the posterior peripheral zone in stage T1c and stage T2 cancers, respectively. The unique cancer detection rate at the anterior peripheral zone was significantly higher in stage T1c cancers than in stage T2 cancers. Therefore, when the prostate is extensively biopsied using the transperineal approach, cancer positive cores are characteristically distributed anteriorly in stage T1c cancers and posteriorly in stage T2 cancers. CONCLUSIONS: TRUS-guided transperineal systematic 14-core biopsy showed an apico-anterior distribution of cancer foci in stage T1c prostate cancers. 相似文献

AIM: To establish whether extended transrectal (TR) and extended transperineal (TP) biopsies are equivalent in detecting prostate cancer. METHODS: Due to an elevated prostate-specific antigen (PSA) greater than 2.5 ng/mL or abnormal digital rectal examination findings, 783 men underwent a transrectal ultrasound-guided three-dimensional 26-core biopsy, a combination of TR 12-core and TP 14-core biopsies. Using recursive partitioning, the best combination of sampling sites that gave the highest cancer detection rate at a given number of biopsy cores was selected either with a TR or a TP approach. The cancer detection rate and characteristics of detected cancers were compared between the TP 14-core and the TR 12-core biopsies and between selected subset biopsy schemes. RESULTS: Prostate cancer was detected in 283 of the 783 men (36%). There was no statistical difference in cancer detection rate or in the characteristics of detected cancers between TP 14-core and TR 12-core biopsies. As far as the best combination of sampling sites was selected, there was no statistical difference in cancer detection rates or in the characteristics of detected cancers between the TP and the TR subset biopsy schemes up to 12 cores. TP and TR biopsies performed equally, regardless of a history of negative biopsy, a digital rectal examination finding, the PSA level or the prostate volume. CONCLUSIONS: We demonstrated for the first time that extended TP biopsy is as effective as its TR counterpart in detecting cancer and the characteristics of detected cancers, as far as sampling sites are selected to maximize the cancer detection rate. 相似文献
