Oral Fleroxacin Prophylaxis in Transurethral Surgery

Prophylactic antibiotics for preventing infection after continence surgery in women with stress urinary incontinence

BACKGROUND

Surgical options for treating stress urinary incontinence (SUI) are usually explored after conservative interventions have failed. Surgeries fall into two categories: traditional techniques (open surgery) and minimally invasive procedures, such as laparoscopic procedures, midurethral sling and injections with urethral bulking agents. Postsurgery infections, such as infections of the surgical site or urinary tract, are common complications. To minimise the risk of postoperative bacterial infections, prophylactic antibiotics may be given before or during surgery.  OBJECTIVES: To assess the effects of prophylactic antibiotics for preventing infection following continence surgery in women with stress urinary incontinence.  SEARCH METHODS: We searched the Cochrane Incontinence Specialised Register, which contains trials identified from CENTRAL, MEDLINE, MEDLINE In-Process, MEDLINE Epub Ahead of Print, CINAHL, ClinicalTrials.gov and WHO ICTRP; and handsearched journals and conference proceedings to 18 March 2021. We also searched the reference lists of relevant articles.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and quasi-RCTs assessing prophylactic antibiotics in women undergoing continence surgery to treat SUI.

DATA COLLECTION AND ANALYSIS

Two review authors selected potentially eligible trials, extracted data and assessed risk of bias. We expressed results as risk ratios (RR) for dichotomous outcomes and as mean differences (MD) for continuous outcomes, both with 95% confidence intervals (CIs). We assessed the certainty of evidence using the GRADE approach.

MAIN RESULTS

We identified one quasi-RCT and two RCTs, involving a total of 390 women. One study performed retropubic urethropexy surgery requiring a transverse suprapubic incision, while the other two studies performed midurethral sling surgery. It should be noted that none of the included studies clearly specified the timing of outcome assessment. We are very uncertain whether prophylactic antibiotics (cefazolin) have an effect on surgical site infections (RR 0.56, 95% CI 0.03 to 12.35; 2 studies, 85 women; very low-certainty evidence) or urinary tract infections or bacteriuria (RR 0.84, 95% CI 0.05 to 13.24; 2 studies, 85 women; very low-certainty evidence). The effect of prophylactic antibiotics (cefazolin) on febrile morbidity is also uncertain (RR 0.08, 95% CI 0.00 to 1.29; 2 studies, 85 women; very low-certainty evidence). We are very uncertain whether prophylactic antibiotics (cefazolin) have any effect on mesh exposure (RR 0.32, 95% CI 0.01 to 7.61; 1 study, 59 women; very low-certainty evidence). None of the three included studies described the assessment of adverse events from antibiotic use, sepsis or bacteraemia in their reports.

AUTHORS' CONCLUSIONS

Only limited data are available from the three included studies and, overall, the certainty of evidence was very low. Moreover, the three included studies evaluated different surgical procedures and dosages of antibiotic administration. Thus, there is insufficient evidence to support or refute the use of prophylactic antibiotics to prevent infection following anti-incontinence surgery. In addition, there were no data regarding adverse effects of prophylactic antibiotics. More RCTs are required.

Perioperative Antimicrobial Prophylaxis in Urology: a Multi-Center Prospective Study

Since there are few published reports regarding the impact of urologic surgery on perioperative infections, an epidemiologic analysis was performed on data from 1,156 open or laparoscopic operations in urology collected by the 21 hospitals participating in this study between September 2002 and August 2003. Prophylactic antibiotics were administered intravenously according to our protocol designed on the basis of the invasiveness and contamination levels. The surgical site infection (SSI) rates following clean, clean-contaminated and contaminated surgery were 1.2%. 5.8% and 23.4%, respectively, while the remote infection (RI) rates were 3.5%. 7.1% and 35.9%, respectively. Methicillin-resistant Staphylococcus aureus (MRSA) was most frequently isolated from SSIs as well as RIs, whereas Enterococcus faecalis and Pseudomonas aeruginosa were more frequently discovered in RIs than in SSIs. Several risk factors for SSI and/or RI, such as older age, high ASA score, obesity, diabetes, preoperative chemotherapy, long operation time and much blood loss, were identified by univariate analysis.

Antibiotic prophylaxis for short-term catheter bladder drainage in adults

BACKGROUND

Urinary tract infections account for about 40% of hospital-acquired (nosocomial) infections, and about 80% of urinary tract infections acquired in hospital are associated with urinary catheters.

OBJECTIVES

To determine if certain antibiotic prophylaxes are better than others in terms of prevention of urinary tract infections, complications, quality of life and cost-effectiveness in short-term catheterisation in adults.

SEARCH METHODS

We searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and MEDLINE in Process, and handsearching of journals and conference proceedings (searched 31st October 2012). Additionally, we examined all reference lists of identified trials.

SELECTION CRITERIA

All randomised and quasi-randomised trials comparing antibiotic prophylaxis for short-term (up to and including 14 days) catheterisation in adults.

DATA COLLECTION AND ANALYSIS

Data were independently extracted by all review authors and compared. Disagreements were resolved by discussion. Data were processed as described in the Cochrane Handbook for Systemtic Reviews of Interventions. Where data had not been fully reported, clarification was sought directly from the authors of the trial.

MAIN RESULTS

Six parallel-group randomised controlled trials with 789 participants met the inclusion criteria. All six trials compared antibiotic prophylaxis versus no prophylaxis. Studies presented a low to unclear risk of bias with similar interventions and measured outcomes.The primary outcome of bacteriuria was less common in the prophylaxis group amongst surgical patients with asymptomatic bacteriuria (I(2) = 0; risk ratio (RR) 0.20; 95% confidence interval (CI) 0.13 to 0.31) . Two non-surgical studies could not be combined in a meta-analysis due to heterogeneity and only one showed significantly fewer cases of bacteriuria (RR 0.19; 95% CI 0.09 to 0.37).Two trials of surgical patients with asymptomatic bacteriuria only (255 participants) compared one type of antibiotic prophylaxis with another and neither study showed a significant difference in cases of bacteriuria.One study (78 participants) compared antibiotic prophylaxis in patients at catheterisation only versus antibiotic prophylaxis throughout catheterisation period with asymptomatic bacteriuria. Antibiotics at catheterisation only, resulted in significantly fewer cases of bacteriuria than giving prophylaxis throughout the catheterisation period (RR 0.29 95% CI 0.09 to 0.91).Secondary data of pyuria were provided by two surgical studies (255 participants). When studies were pooled, pyuria occurred in significantly fewer cases in the prophylactic antibiotic group (RR 0.23, 95% CI 0.13 to 0.42). The number of gram-negative isolates in patients' urine just before catheter removal in one study (RR 0.05, 95% CI 0.00 to 0.79) and six weeks after hospital discharge (RR 0.36, 95% CI 0.23 to 0.56) were significantly lower. There were no events in the treatment group before catheter removal. When pooled data from two studies showed significantly reduced febrile morbidity in those receiving antibiotic prophylaxis (RR 0.53 95% CI 0.31 to 0.89).Although all studies assessed micro-organisms isolated from the urine specimens the data were too heterogenous to pool in a meta-analysis and have been provided in a narrative form. Further secondary data such as economic analysis, length of stay and quality of life were not covered in detail.

AUTHORS' CONCLUSIONS

The limited evidence indicated that receiving prophylactic antibiotics reduced the rate of bacteriuria and other signs of infection, such as pyuria, febrile morbidity and gram-negative isolates in patients' urine, in surgical patients who undergo bladder drainage for at least 24 hours postoperatively. There was also limited evidence that prophylactic antibiotics reduced bacteriuria in non-surgical patients.

Japanese guidelines for prevention of perioperative infections in urological field

For urologists, it is very important to master surgical indications and surgical techniques. On the other hand, the knowledge of the prevention of perioperative infections and the improvement of surgical techniques should always be considered. Although the prevention of perioperative infections in each surgical field is a very important issue, the evidence and the number of guidelines are limited. Among them, the preparation of guidelines has progressed, especially in gastrointestinal surgery. The Center for Disease Control and Prevention (CDC) proposed guidelines for the prevention of surgical site infections, which have been used worldwide. In urology, the original guidelines were different from those of general surgery, due to many endourological procedures and urine exposure in the surgical field. The Japanese Society of UTI Cooperative Study Group has thus framed these guidelines supported by The Japanese Urological Association. The guidelines consist of the following nine techniques: open surgeries, laparoscopic surgeries, transurethral resection of bladder tumor, ureterorenoscope and transurethral lithotripsy, transurethral resection of the prostate, prostate biopsy, cystourethroscope, pediatric surgeries in the urological field, and extracorporeal shock wave lithotripsy and febrile neutropenia. These are the first guidelines for the prevention of perioperative infections in the urological field in Japan. Although most of these guidelines were made using reliable evidence, there are parts without enough evidence. Therefore, if new reliable data is reported, it will be necessary for these guidelines to be revised in the future.

Antibiotic policies for short-term catheter bladder drainage in adults

BACKGROUND

Urinary tract infections account for about 40% of hospital-acquired (nosocomial) infections, and about 80% of urinary tract infections acquired in hospital are associated with urinary catheters.

OBJECTIVES

To determine if certain antibiotic policies are better than others in terms of prevention of urinary tract infections, complications, quality of life and cost-effectiveness in short-term catheterised adults.

SEARCH STRATEGY

We searched the Cochrane Incontinence Group Specialised Register (searched 20 December 2004). Additionally, we examined all reference lists of identified trials.

SELECTION CRITERIA

All randomised and quasi-randomised trials comparing antibiotic policies for short-term (up to and including 14 days) catheterization in adults.

DATA COLLECTION AND ANALYSIS

Data were extracted by both reviewers independently and compared. Disagreements were resolved by discussion. Data were processed as described in the Cochrane Handbook. If data had not been fully reported, clarification was sought directly from the authors of the trial.

MAIN RESULTS

Six parallel-group randomised controlled trials met the inclusion criteria. In one trial comparing antibiotic prophylaxis with giving antibiotics when clinically indicated amongst female surgical patients who had a urethral catheter for more than 24 hours, symptomatic urinary tract infection was less common in the prophylaxis group (RR 0.20, 95% CI 0.06 to 0.66). Five trials compared antibiotic prophylaxis with giving antibiotics when microbiologically indicated, bacteriuria, pyuria and gram-negative isolates in patients' urine were less common in the prophylaxis group amongst surgical patients with bladder drainage for at least 24 hours postoperatively. Bacteriuria rates were also about five-fold lower in the prophylaxis group in trials involving urological surgery patients and non-surgical patients. No trial compared giving antibiotics when microbiologically indicated with giving antibiotics when clinically indicated.

AUTHORS' CONCLUSIONS

There was weak evidence that antibiotic prophylaxis compared to giving antibiotics when clinically indicated reduced the rate of symptomatic urinary tract infection in female patients with abdominal surgery and a urethral catheter for 24 hours. The limited evidence indicated that receiving antibiotics during the first three postoperative days or from postoperative day two until catheter removal reduced the rate of bacteriuria and other signs of infection such as pyuria and gram-negative isolates in patients urine in surgical patients with bladder drainage for at least 24 hours postoperatively. There was also limited evidence that prophylactic antibiotics reduced bacteriuria in non-surgical patients.

Double-blind randomized comparison of single-dose ciprofloxacin versus intravenous cefazolin in patients undergoing outpatient endourologic surgery

OBJECTIVES

To compare the efficacy of single-dose oral ciprofloxacin with intravenous cefazolin as a prophylactic agent in patients undergoing outpatient endourologic surgery.

METHODS

One hundred patients were enrolled in a double-blind, randomized study to receive either ciprofloxacin (500 mg) or cefazolin (1 g) before surgery. A postoperative clinical evaluation and urine cultures were performed 5 to 10 days after surgery. Patients undergoing ureteral stent insertion or exchange, ureteroscopy, bladder biopsy, retrograde pyelography, collagen injection, and internal urethrotomy were included.

RESULTS

Postoperative urinary tract infection occurred in 7 (9.1%) of 77 patients, including 3 (8.1%) of 37 and 4 (10.0%) of 40 of those who received ciprofloxacin and cefazolin, respectively (P = 0.77). There were no episodes of sepsis, and no patient with infection required hospitalization. The total cost associated with the administration of prophylactic antibiotics in the study population was $3657 less in those 50 patients who received ciprofloxacin than in the 50 patients who received cefazolin.

CONCLUSIONS

A single oral dose of ciprofloxacin in patients undergoing outpatient endourologic surgery was equally effective as cefazolin in preventing postoperative urinary tract infection, but was associated with markedly lower overall costs.

An economic analysis of antimicrobial prophylaxis against urinary tract infection in patients undergoing transurethral resection of the prostate

Despite the high level of safety and low incidence of mortality associated with transurethral resection of the prostate (TURP), urinary tract infections (UTIs)-the most common complication associated with this procedure-continue to be an important source of postoperative morbidity and costs. However, there is controversy about whether antimicrobial agents should be used as UTI prophylaxis in patients undergoing TURP and, if so, which agents should be used and for what duration. This retrospective study used multivariate regression analysis to evaluate the different types and durations of antibiotic prophylaxis in 222 patients who underwent TURP at a Veterans Affairs hospital between January 1, 1995, and March 30, 1998. The primary outcome measures were total medical costs (ie, medication use, clinic office visits, and hospital care in the 4 weeks after the procedure), length of hospital stay (total days in hospital due to the procedure), and probability of UTI (incidence of infection in the 4 weeks after the procedure). Results showed that there was no difference in the length of hospital stay regardless of the regimen or duration of pre-TURP antibiotic therapy. Patients who received pre-TURP ampicillin plus ceftizoxime incurred moderately higher total medical costs than did patients who received the least costly drug, cefazolin (P = 0.10). Similarly, patients who received post-TURP quinolones incurred a significantly higher total medical cost than did patients who received co-trimoxazole (P = 0.06). We found no evidence of a relationship between use of specific parenteral or oral antibiotic prophylaxis for UTI in patients undergoing TURP and the rate of UTI in such patients. Thus there is no justification for the use of more expensive antibiotic regimens. At our institution, the preferred pre-TURP prophylactic regimen would be cefazolin, whereas co-trimoxazole would be the most cost-effective post-TURP prophylactic regimen. Because duration of post-TURP prophylaxis does not appear to influence the rate of UTI, 24 hours would seem adequate.

Single-dose antibiotic prophylaxis in transurethral resection of the prostate: a prospective randomized trial

OBJECTIVE

To evaluate the efficacy of single-dose antibiotic prophylaxis in transurethral resection of the prostate (TURP).

PATIENTS AND METHODS

A total of 139 patients were entered into a prospective randomized trial comparing single-dose antibiotic prophylaxis with no antibiotic before surgery. Twelve patients were excluded because they had significant bacteriuria before surgery (defined as > or = 10(5) bacteria/mL). Of the remaining 127 patients, 62 were allocated to the single-dose group (A) and 65 to the no-antibiotic group (B). All 62 patients in group A received 1 g of ceftriaxone intravenously 1-2 h before surgery with the anaesthetic premedication, the 65 in group B receiving none. Urine cultures were collected post-operatively as the catheter was removed and again 4 weeks after hospitalization.

RESULTS

The incidence of post-operative bacteriuria was statistically significantly different, occurring in five patients (9%) in group A and 16 patients (26%) in group B (Fisher's exact test, one-tail P = 0.009). There was no significant difference between the groups 4 weeks after hospitalization. The overall incidence of bacteriuria post-operatively and 4 weeks after hospitalization was 11 patients (18%) in group A and 22 patients (34%) in group B (P = 0.03).

CONCLUSION

Single-dose antibiotic prophylaxis with 1 g of ceftriaxone intravenously is effective in patients undergoing TURP and is recommended for such surgery.
