It should be recommended only when the potential benefit exceeds the anticipated risks and costs. However, a wide variation in the use of periprocedural prophylactic antibiotics has been demonstrated, which frequently is incurred as an inappropriate selection of antimicrobials, inadequate schedule of administration or excessive duration of prophylaxis.\n\nThe increase in multidrug resistance of antibiotics in recent decades has been associated with its misuse, resulting in an increased rate of morbidity and mortality, prolonged hospital stays and increased care costs. Specifically, resistance to fluoroquinolones has increased its prevalence, a group of antibiotics widely used in urology. Therefore, local resistance patterns should be considered before following recommendations, especially in populations with poor control of antimicrobial use.\n\nTransurethral resection of bladder (TURB) has become a frequent surgical procedure, as it is the main diagnostic and therapeutic tool for bladder cancer, representing the ninth most common malignancy in the world. However, no recent randomized clinical trial has investigated antimicrobial prophylaxis for TURB. It is well known that an expected complication of TURB is urinary tract infection (UTI), which is the most common healthcare related infection worldwide.\n\nUnder this premise, a randomized clinical trial is proposed to analyze the current panorama of UTI as a transcendent postoperative complication of TURB, under the context of the new emerging resistance parameters. The use of fosfomycin trometamol is proposed as a good potential option for urological procedures due to its high activity against multidrug-resistant gram-negative bacteria and its favorable pharmacokinetic parameters that guarantees wide tissue penetration and a high urinary concentration, in a single dose, the which will be compared with the control group with traditional prophylaxis (amikacin). The relative risk of UTI will be estimated, as well as the attributable risk of the main risk factors associated with this infection, allowing a better characterization of this population for adequate decision making regarding this clinical challenge.', 'detailedDescription': 'In 1931, Stern and McCarthy created the first practical cut-out resectoscope, allowing endoscopic diagnosis and treatment of bladder tumors for the first time in history. From now on, TURB has been the cornerstone of the management of bladder tumors. Histological evaluation is essential for the precise classification and staging of this cancer, as well as the therapeutic modality of choice for most patients with bladder cancer\n\nEpidemiology Bladder cancer is the most common malignancy of the urinary tract, being the seventh most common cancer in men and number 17 in women. The worldwide incidence is 9 per 100,000 men and 2 per 100,000 women. More than 75,000 new cases of bladder cancer are diagnosed in the United States of America annually, making bladder cancer the ninth most common malignancy of the urinary tract. In addition, bladder cancer is responsible for 15,000 annual deaths in the United States of America, which makes it the thirteenth cause of death in general and the second most common cause of death among genitourinary tumors\n\nIn Latin America, bladder cancer has an incidence of 5.6 per 100,000 inhabitants. Mexico lacks reliable records of cancer epidemiology, however, in Mexico it corresponds to 14.4% of genitourinary cancers, ranking as the fourth most frequent. Mortality in men is 3 per 100,000 and in women 1 per 100,000 with very high geographical variation due to unequal access to health services. In a second level hospital in Mexico City were reported 861 cases of genitourinary cancer, bladder cancer was accounted for 13%.\n\nUrinary tract infection as a postoperative complication In urology, the act of instrumentation is a potential contributor of infection risk.\n\nBefore finalizing the TURB, a urethral catheter is placed to irrigate and wash the bladder three times with 100 mL of saline. At the end of the procedure, the bladder is completely drained and the function of the catheter is guaranteed to assess a subsequent irrigation in the postoperative period, for complications that may occur, such as haematuria or urinary retention due to obstruction of a clot and / or irrigation of intravesical chemotherapy. In the absence of complications, the catheter can be removed after 24 hours.\n\nThe risk of urinary tract infection is directly proportional to the duration of the catheterization, measured in days (catheter days) and the surgical time. It is reported a mean catheter day of 1.9 +/- 1.7 in 130 post-TURB patients. It is well known that urinary tract infection (UTI) associated with catheter use is the most common healthcare related infection in the world and is the result of widespread use of urinary catheterization. The incidence reported of UTI in the literature after surgery is 5-10%. Antimicrobial prophylaxis in TURB decreases the risk of UTI from 10.1% to 2.9%. In a series of 10,559 patients in the United States of America the incidence of UTI in post-TURB patients was 3 to 5%, being the most observed complication. The investigators concluded that as surgery time increased, urinary tract infection increased (2.8% in 0-30min to 5.4% in\\> 90 min, P \\<0.001).\n\nIn addition, a patient with cancer is a host with increased susceptibility to acquire infections. In the last 50 years the epidemiology of bacterial infections in cancer patients has presented a continuous change influenced by the nature and intensity of chemotherapeutic and immunosuppressive regimes and the widespread use of empirical and prophylactic antibiotics\n\nAntimicrobial prophylaxis in TURB Surgical antimicrobial prophylaxis is the systemic administration of an antibiotic before, during and / or shortly after a urological procedure aimed to reduce the risk of local and systemic postoperative infections, such as urinary tract infection or surgical site infection. The optimal antimicrobial drug should be a microbiologically active agent against the most frequent potential pathogens and must have good pharmacological properties.\n\nAntibiotics The antibiotics used for prophylaxis must be effective against the characteristic bacterial microbiota of the surgical site and relevant to the disease. In addition, it must be considered the properties of the antimicrobial agent, such as cost, convenience and safety. It should reach tissue serum levels that exceed the minimum inhibitory concentration for microorganisms characteristic of the surgical site, in this case Enterobacteriaceae and Enterococci. Moreover, it must have a long half-life to maintain sufficient serum and tissue concentrations throughout the procedure without the need to administer another dose. It must be safe, cheap and unlikely to promote bacterial resistance.\n\nFor the urinary tract, cephalosporins, fluoroquinolones and aminoglycosides are generally effective, have a long half-life, are cheap (when used as a single dose) and are rarely associated with allergic reactions. In addition, fluoroquinolones and aminoglycosides can be used in patients with a beta-lactam allergy. These antimicrobials can effectively cover the expected organisms and meet the criteria indicated above.\n\nCurrent recommendations and the context in Mexico The American Urological Association (AUA) and the Japanese guidelines recommend the use of fluoroquinolones, trimethoprim- sulfamethoxazole, penicillins, first or second generation cephalosporins or aminoglycosides before the start of TURB as an antimicrobial prophylaxis. According to the guidelines of the Canadian Urology Association (CUA), any randomized clinical trials of antimicrobial prophylaxis in TURB were found, so the recommendations about antibiotic prophylaxis are based on other endoscopic urological procedures. Use of fluoroquinolone are recommended for prophylaxis before surgical procedure, also trimethoprim- sulfamethoxazole or third generation cephalosporins can be used.\n\nIn a study of TURB in 2006, the investigators used oral levofloxacin 200mg as prophylactic antibiotic, which was given 30-60 minutes before the procedure. However, in this context it would not be convenient to use this regime, because in a study conducted in 2015 specified that countries with poor control of the use of antimicrobials such as Mexico, there is a trend towards bacterial resistance, placing fluoroquinolones as the second line of treatment in urinary tract infection . An important cause of the emergence of these resistant strains is the excessive use (treatment when it is not needed and prolonged exposure to therapy) of antimicrobial agents for all indications.\n\nFluoroquinolone-based regimens, a pillar of prophylaxis guidelines, are increasingly ineffective due to a constant increase in multidrug-resistant gram-negative bacteria (MDR). The same concerns apply with second and third generation cephalosporins, which have resistance problems and, if administered orally, do not have a good penetration in tissues such as prostate.\n\nProblem definition Since 2000 a serious global public health problem has arisen in relation to the increase in antimicrobial resistance, particularly among the pathogens of the ESKAPE group (Enterococcus faecium, Staphylococcus aureus, Clostridium difficile, Acinetobacter species, Pseudomona aeruginosa and Enterobacteriaceae), which are microorganisms that cause urinary tract infection. In addition to the increase in multidrug resistance to antibiotics and their misuse, this has been associated with an increased rate of morbidity and mortality, prolonged hospital stay and increased care costs.That\'s why antimicrobial prophylaxis is of such magnitude and importance that it needs to be updated to its reasoned use in order to improve its performance.\n\nIn the case of TURB, there is little evidence in the literature that recommends the use of preoperative antimicrobial prophylaxis in TURB, due to the lack of studies on this subject. The incidence of UTI in TURB has been reported between 2 to 39% and risk of infection in TURB from 18 to 75%.\n\nJustification Nosocomial infection has been associated with an increased length of postoperative stays, rate of hospital readmission and the outpatient use of antimicrobial agents, which significantly increases the costs and use of medical resources.\n\nOptimally, the specific prophylactic regimen should be supported by clinical trials evidence. In many cases, randomized clinical trials are not available. Such lack of data does not impede the adequacy of some antibiotic regimes based on the efficacy of the drugs, the cost, safety and knowledge of the microbiota of the surgical site. When selecting the antimicrobial for prophylaxis, the clinician should be aware of the different resistance patterns in the local community. Specifically, resistance to fluoroquinolones, which has increased their prevalence, therefore, should be considered due to the high use of these agents for antimicrobial prophylaxis in urological surgery.\n\nRegarding the premise, "surgical antimicrobial prophylaxis is recommended only when the potential benefit exceeds the risks and anticipated costs," information on the costs associated with the prophylactic use of antimicrobials specifically for urological surgery cannot be easily obtained, however, data from other surgical disciplines can guide us in making decisions. For example, the use of prophylaxis in transurethral resection of the prostate, where there are multiple clinical trials and it is recommended the use of prophylaxis with pre-procedure third-generation cephalosporins. On the contrary, excessive and / or inappropriate antimicrobial prophylaxis increases costs, which can be reduced with measures to improve commitment with evidence-based recommendations. In general, the financial costs of prophylaxis are controlled using the least expensive and safest effective agent for the shortest time that is compatible with good clinical practice.\n\nThere are currently few randomized clinical studies (conducted more than 25 years ago) on the subject. In 1988 a randomized clinical trial was conducted with 243 patients undergoing TURB, three perioperative doses of cefradine were compared with placebo, observing a significant reduction in the rate of bacteriuria. However, no similar randomized clinical trials have been performed, as well as for other cystoscopic procedures that involve transurethral manipulation (bladder biopsy, ureteral catheterization, laser prostatectomy, etc.). For this reason, updated and available evidence is required for this widely used procedure.\n\nThe American Urological Association and the Japanese guidelines recommend the use of fluoroquinolones, trimethoprim, penicillins, first or second generation cephalosporins or aminoglycosides before the start of TURB as an antimicrobial prophylaxis In countries with poor control of the use of antimicrobials such as Mexico, there is a tendency towards bacterial resistance, placing fluoroquinolones as the second line of treatment for urinary tract infection. Therefore, the use of fluoroquinolone-based regimens, a pillar of prophylaxis guidelines, is increasingly ineffective due to a constant increase in resistant multidrug gram negative bacteria. The same applies with second and third generation cephalosporins, which also have resistance problems.\n\nIn 2007 a randomized clinical trial was performed and the effectiveness of fosfomycin against cefotiam to prevent infections associated with urological surgery was compared ,the response rates reported were 92.9% for fosfomycin and 94.9% for cefotiam in patients with transurethral surgery. Therefore, fosfomycin trometamol may be a potential option for urological procedures, due to its high effectiveness against resistant multidrug gram negative bacteria and its favorable pharmacokinetic parameters.\n\nThe aim of the study is to provide evidence to help clarify the usefulness and feasibility of antimicrobial prophylaxis, being fosfomycin trometamol an antibiotic that meets the necessary characteristics for this intervention. Therefore it will contribute to the characterization of the population that undergoes this procedure, which includes the description of risk factors and microbiological characteristics, such as the identification of emerging resistant strains. The results obtained will contribute towards the decision-making of this and other cytoscopic procedures due to the similarities in terms of invasiveness and possible tissue trauma, suggesting that the data regarding transurethral bladder resection can reasonably be extrapolated to other cystoscopic procedures with manipulation. The above will be compared with the antimicrobial prophylaxis that usually occurs in the Instituto Nacional de Ciencias Medicas y Nutricion Salvador Zubiran which is based on aminoglycosides (Amikacin) administered in anesthetic induction before the surgical procedure.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Patients 18 years old of age\n* Patients with a programmed TURB\n* Absence of urinary tract infection (negative urine culture and no clinical manifestations for urinary tract infection)\n\nExclusion Criteria:\n\n* Patients with asymptomatic bacteriuria\n* Patients with positive urine culture before procedure\n* Patients with urinary catheterization'}, 'identificationModule': {'nctId': 'NCT04209192', 'briefTitle': 'Antimicrobial Prophylaxis in Patients Who Underwent a Transurethral Resection of Bladder (TURB)', 'organization': {'class': 'OTHER', 'fullName': 'Instituto Nacional de Ciencias Medicas y Nutricion Salvador Zubiran'}, 'officialTitle': 'Randomized Phase II Study of Antibiotic Prophylaxis With Fosfomycin vs Amikacin in Transurethral Resection of Bladder', 'orgStudyIdInfo': {'id': 'URO-2995-19-20-1'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Control group (Amikacin)', 'description': 'Patients in the control group will receive amikacin as prophylactic antibiotic.
