ABSTRACT

OBJECTIVES: To evaluate a regimen of targeted prophylaxis using rectal swab culture in patients undergoing transrectal ultrasound-guided prostate biopsy, and to investigate the characteristics of isolated fluoroquinolone-resistant Escherichia coli. METHODS: A prospective study was carried out from June 2013 through December 2014. Rectal swabs were cultured on agar plates containing either 2 µg/mL levofloxacin or 1 µg/mL sitafloxacin before transrectal ultrasound-guided prostate biopsy. Patients with susceptible organisms received levofloxacin or sitafloxacin, whereas those with resistant organisms received directed antimicrobial prophylaxis according to the results of the antimicrobial susceptibility test. Patients with infectious complications after prostate biopsy were identified, and characteristics of patients carrying fluoroquinolone-resistant Escherichia coli were analyzed. RESULTS: A total of 397 men underwent transrectal ultrasound-guided prostate biopsy. Of these patients, 74 (18.6%) had fluoroquinolone-resistant Escherichia coli. All fluoroquinolone-resistant Escherichia coli were susceptible to amikacin and meropenem. The risk factor for possible fluoroquinolone-resistant Escherichia coli was age of ≥73 years. Three (0.7%) patients who received appropriate antimicrobial prophylaxis had high-grade fever after the prostate biopsy. However, the pathogens were not fluoroquinolone-resistant Escherichia coli. CONCLUSIONS: Targeted antimicrobial prophylaxis in patients undergoing transrectal ultrasound-guided prostate biopsy can be associated with reducing severe infectious complications caused by fluoroquinolone-resistant Escherichia coli.

ABSTRACT

The number of patients with acute cystitis caused by extended spectrum ß lactamase (ESBL)-producing Escherichia coli (E. coli) is increasing gradually. Although it is reported that ESBL-producing E. coli are sensitive to faropenem (FRPM), there are few clinical studies on the efficiency of FRPM against acute cystitis caused by the bacteria. Therefore, we retrospectively reviewed the medical charts of patients with acute cystitis caused by ESBL-producing E. coli who were treated with the oral antimicrobial agent faropenem (FRPM) in our institution from June 2011 to May 2015. Ten patients with acute cystitis caused by ESBL producing E. coli were treated with FRPM. Although clinical cure was achieved in 9 of them, it reoccurred in 3. This study revealed that the treatment regimen with FRPM for patients with acute cystitis caused by ESBL-producing E. coli is promising. However, a non-negligible number of recurrences were caused by ESBL-producing E. coli because of the nature of underlying diseases or pathologies in the urinary tract.

ABSTRACT

We report a patient with infective endocarditis and pyrogenic spondylitis occurring simultaneously. The patient was a 59-year-old man. He was suspected of having prostate cancer due to a high prostate-specific antigen concentration noted in a checkup. He then underwent a transrectal ultrasound guided prostate biopsy with cefotiam as antimicrobial prophylaxis. He had a fever higher than 38 °C and lumbar pain for a few days after the biopsy. Enterococcus faecalis was isolated from 2 sets of blood culture. Magnetic resonance imaging revealed an abnormal image at C7/Th1 with a signal decrease in T1-weighted sequences and signal increase in T2-weighted sequences that were suspected to be due to bone destruction. Therefore, he was diagnosed as having pyogenic spondylitis by an orthopedist. At the same time, he complained of palpitation and a heart murmur was detected. Then transesophageal echocardiography was performed by a cardiologist and it revealed vegetation in his left ventricle and aortic regurgitation, and finally acute cardiac insufficiency was determined. He was treated with tazobactam/piperacillin and aortic valve displacement surgery. Based on the results of the prostate biopsy and image inspection, he was diagnosed as having localized prostate cancer. He was treated by androgen deprivation therapy and external beam radiation therapy. We have to keep in mind that E. faecalis can be a potential pathogen for severe infectious complications after prostate biopsy, especially if a cephalosporin is selected for antimicrobial prophylaxis.

ABSTRACT

OBJECTIVE: We evaluated who would need further evaluations such as retrograde pyelography (RP) and/or ureteroscopy to diagnose upper urinary tract urothelial cancers (UUTUCs) when abnormal findings for the upper urinary tract (UUT) were detected by enhanced computed tomography (CT). METHODS: We retrospectively analyzed 125 patients who underwent enhanced CT for various reasons and had abnormal findings for the UUT. Patients whose tumors were suspected to be of extraureteral origin were excluded. All patients received RP and/or ureteroscopy to evaluate the UUTUCs. RESULTS: The median age of the 125 patients was 70 years and gross hematuria (26.4%) was the most frequently observed symptoms. RP, ureteroscopy and both were performed for 121, 59 and 55 patients, respectively. CT revealed tumor-like lesions in 58 patients and the other patients had non-tumor-like lesions. UUTUCs were found in 43 (34.4%) of the 125 patients. All of them had tumor-like lesions on CT. In 58 patients who had tumor-like lesions on CT, univariate and multivariate analyses revealed that tumor diameter and tumor enhancement were significant predictive factors for UUTUCs. ROC curve analysis of enhanced CT to diagnose UUTUCs revealed that a tumor diameter of 18 mm was the best cutoff point. The sensitivity, specificity and accuracy were 90.0%, 98.8% and 92.7% for RP and 95.5%, 100% and 97.1% for ureteroscopy, respectively. Both of them had high sensitivity, specificity and accuracy. CONCLUSION: We should decide to evaluate the UUT according to the tumor diameter on enhanced CT. When we evaluate the UUT in patients with tumor diameters of less than 20 mm, ureteroscopy is recommended.

ABSTRACT

One of the major complications of clean intermittent catheterization (CIC) is urinary tract infection (UTI). Recent reports showed that community-acquired UTIs caused by antimicrobial-resistant pathogens were gradually presenting in adults. However, there have been few reports about UTIs caused by antimicrobial-resistant bacteria in pediatric patients. Therefore, we retrospectively reviewed the medical charts of 45 children with CIC due to neurogenic bladder dysfunction from January 2010 to March 2013. Sixty-two episodes of cystitis occurred in 27 patients. Seventy bacterial strains were isolated from urine samples. The rate of Gram-negative bacteria was 84.3%. Six extended-spectrum ß-lactamase (ESBL)-producing Escherichia coli (E. coli) strains were isolated from 4 patients. An ESBL-producing Proteus mirabilis strain and a methicillin-resistant Staphylococcus aureus strain were isolated from one patient each. Most of the pathogens of cystitis in the pediatric patients with CIC were Gram-negative bacilli, especially E. coli. We should be aware that ESBL producing E. coli as potential pathogens cause cystitis and regularly survey antimicrobial susceptibility to understand the resistant strains that develop.

ABSTRACT

We retrospectively reviewed the medical records of patients with metastatic clear cell renal cell carcinoma who received molecular targeted therapy between 2005 and 2011. Cancer-specific survival was analyzed using the Kaplan-Meier method. Predictors of cancer-specific survival were analyzed using the Cox regression hazards model. A total of 89 patients, consisting of 50 first line patients and 39 patients receiving prior cytokine were included in the analysis. The two-year cancer-specific survival rate of the firstlinegroup was 60.2% and that of theprior cytokinethe rapy group was 62.1%. In univariateanalysis, Karnofsky performance status (KPS)<80%, time from diagnosis to treatment less than one year, bone metastasis and C-reactive protein (CRP)>1.3 mg/dl in were statistically significant prognostic factors (p<0.05). In multivariate analysis, time from diagnosis to treatment less than one year (HR 2.46, 95%CI 1.11-5.82, p=0.025) and CRP (HR 4.92, 95%CI 2.23-11.3, p<0.001) were independent prognostic factors. Time from diagnosis to treatment less than one year and CRP were independent prognostic factors in patients who received molecular targeted therapy.

ABSTRACT

We examined the usefulness of measurement of procalcitonin (PCT) for patients, who developed febrile neutropenia during cancer chemotherapy for urological cancer. Of the Patients who underwent cancer chemotherapy for bladder, renal pelvic or ureteral, and testicular cancer in our department from 2010 to 2013, 51 had febrile events. Their clinical courses and PCT values were retrospectively reviewed and analyzed. PCT was positive in 12 patients and negative in 39. The duration with febrile status was significantly longer in the PCT-positive group than in the PCT-negative group. There was no significant difference between the blood count values in each group, but C-reactive protein (CRP) was significantly higher in the PCT-positive group than in the PCT-negative group. There were no significant differences between the 2 groups in other tests with blood. There were 12 patients with febrile neutropenia (FN) but all were classified into low-risk by the MASCC scoring system. Four of these 12 patients were positive for PCT. Our results suggested that, in patients with a fever of 37.5°C or more during the course of cancer chemotherapy for urologic cancer, bacteremia possibly existed if the patient was positive for PCT. In addition, the duration of fever tended to be longer and the condition was more severe. When the patients with urological cancer undergo cancer chemotherapy manifest high-grade fever, PCT is promising and valuable as an indicator of the severity of infection.

ABSTRACT

OBJECTIVES: The aims of this study were to clarify the frequency and prognosis of febrile neutropenia (FN) in patients who received urological anticancer chemotherapy. METHODS: Between May 2005 and January 2010, 141 patients underwent urological anticancer chemotherapy at the Sapporo Medical University Hospital, Sapporo, Japan. They consisted of 124 men and 17 women aged 62 (range 16-80) years. The patients underwent a total of 626 treatment courses of urological anticancer chemotherapy. RESULTS: Of the 626 urological anticancer chemotherapy courses, grades 3 and 4 neutropenia occurred in 451 (72.0 %) courses. FN developed in 57 (9.1 %) courses in which 7 (12.3 %) and 50 (87.7 %) patients were classified as high risk and low risk, respectively, according to the Multinational Association for Supportive Care in Cancer (MASCC) risk index scoring system. There was no anticancer chemotherapy-related death in either the high- or low-risk group. The frequencies of bacteria isolated from courses with FN were 0 and 10.0 % for the high- and low-risk groups, respectively. CONCLUSIONS: According to the MASCC scoring system, there were fewer patients in the high-risk group than in the low-risk group in this study. There were no cases of anticancer chemotherapy-related death in either group. Therefore, urological anticancer chemotherapy can be conducted safely with the proper management of neutropenia and FN.

ABSTRACT

To clarify the discrepancy in the incidence and severity of surgical site infections (SSI) for radical cystectomy between reports based on the CDC guideline and those using the Clavien-Dindo classification we evaluated 449 consecutive patients who underwent radical cystectomy for bladder cancer between 1990 and 2012. Of the 115 (25.6%) patients with SSI defined by the CDC guideline, 89 could be analyzed. We compared the SSI rates and severity defined by the CDC guideline and Clavien-Dindo classifications. There were 58 patients with superficial SSI, 16 with deep SSI, and 15 with organ/space SSI according to the CDC guideline. All patients with organ/space SSI were judged as "not having SSI" by the Clavien-Dindo classification. They were classified as having "intestinal prolapse", "intestinal fistula", "abdominal abscess" and "pelvic abscess." There was a significant association between the treatment duration and depth of SSI based on the CDC guideline by Spearman's rank-correlation coefficient (p < 0.001, r = 0.614) and with the grade of complications (p < 0.001, r = 0.632) in the Clavien-Dindo classification. Multivariate analysis showed that patients with grade III SSI in the Clavien-Dindo classification needed a significantly longer treatment duration. It is necessary to be aware that a discrepancy can occur automatically due to the different natures of the definitions. Using the CDC guideline, we can effectively estimate the future treatment period when SSI occurs. With the Clavien-Dindo classification, grade III SSI requires a longer treatment duration.

ABSTRACT

There is still controversy about whether post-void residual (PVR) urine volume affects the onset of urinary tract infection (UTI). In addition, although male patients with lower urinary tract symptoms (LUTS) might potentially have PVR, the association between LUTS and UTI or asymptomatic pyuria with or without bacteriuria remains unclear. We studied the frequency of asymptomatic pyuria, with and without bacteriuria, in patients with LUTS without a previous history of urinary tract manipulation at the first visit and their sequential courses. This retrospective study was done by reviewing medical charts. A total of 453 male patients who complained of LUTS and visited our outpatient clinic in 2008 were included in this study. The frequency of pyuria, with or without bacteriuria, in this study at the first visit was 4.9%. The median PVR volumes at the initial examination were 79 ml in the 22 patients with pyuria and 22 ml in the 431 patients without pyuria. The difference of the PVR volume between the patients with pyuria and those without pyuria was statistically significant (p = 0.0095). Twelve patients were treated with alpha-blockers without antimicrobial chemotherapy and pyuria disappeared in 5 (41.7%) of them. However, the decrease in the rate of PVR was not significantly different between the patients with persisting pyuria and those without pyuria. A not negligible number of patients with LUTS had pyuria at the first visit; however, there was no febrile UTI in their clinical course even if they received no urological manipulation.

ABSTRACT

We retrospectively investigated the incidence of genitourinary tract infection in 5895 patients who underwent transrectal and/or transperineal prostate biopsy procedure between January and December 2011 at 46 institutions belonging to Japanese Research Group for Urinary Tract Infection (JRGU). The total rate of genitourinary tract infection after prostate biopsy was 0.76%, while that following transrectal procedure was 0.83% and following transperineal procedure was 0.57%, which were not significantly different. In contrast, febrile infection associated with a fever (≥38 °C) occurred significantly more frequently after transrectal (0.71%) than transperineal (0.16%) approach (P = 0.04). Notably, in infectious cases, Escherichia coli was most frequently isolated. Of the 9 E. coli strains isolated by urine culture, 6 (66.7%) produced extended spectrum ß-lactamase (ESBL) and 7 (77.8%) showed levofloxacin resistance. Similarly, of 6 E. coli strains isolated by blood culture, 4 (66.7%) produced ESBL and 6 (100%) showed levofloxacin resistance. When the efficacy of antimicrobial prophylaxis (AMP) with levofloxacin for the patients undergoing transrectal or transperineal biopsy was compared between a single dose (500 mg) and that given for 2 or more days, no significant difference was observed for the rate of infection (transrectal: 0.82% vs. 1.04%, p = 0.94; transperineal: 0.30% vs. 0.46%, p = 0.68). Although a single dose of levofloxacin for AMP is sufficient to prevent genitourinary infection after transrectal or transperineal prostate biopsy, and recommended in this era of increased multi-drug resistant pathogens, the increase in fluoroquinolone-resistant E. coli and ESBL-producing E. coli has emerged as a profound problem for surveillance.

ABSTRACT

To clarify the incidence of surgical site infection (SSI) after urological scrotal and inguinal surgical procedures and the preventive effect of antimicrobial prophylaxis for SSI, retrospective analysis was performed. The patients who underwent scrotal and inguinal operations from 2001 to 2010 were included in this analysis. A first or second generation cephalosporin was administered as antimicrobial prophylaxis just before the start of surgery and no additional prophylaxis was conducted. The surgery was classified into 76 (38%) cases with testicular sperm extraction (TESE), 72 (36%) with radical orchiectomy, 29 (14.5%) with bilateral orchiectomy (surgical castration) and 23 (11.5%) with other scrotal and inguinal operations. The median age and age range were 36 years and 18-81 years, respectively. SSI occurred in 7 (3.5%) cases. The frequencies of SSI were 6.5% in the patients with urological inguinal surgery and 1.6% in those with scrotal surgery. The frequency of SSI in the patients with urological inguinal surgery was not negligible even though it is considered a clean operation, and further analysis is warranted to prevent SSI.

ABSTRACT

To clarify the clinical efficacy of a single oral 2 g dose of azithromycin extended-release for heterosexual male patients with urethritis, and the current antimicrobial sensitivity of Neisseria gonorrhoeae to azithromycin, a prospective clinical trial was conducted from 2011-2013. In patients with gonococcal urethritis, the eradication rate was 90.9% (30 of 33). The susceptibility rates of isolated Neisseria gonorrhoeae strains to ceftriaxone, spectinomycin, cefixime and azithromycin were 100%, 100%, 95.3% (41/43) and 37.2% (16/43), respectively. In the patients with nongonococcal urethritis, the eradication rate was 90.0% (45 of 50). The microbiological eradication rates for the pathogens were 90.9% (30/33) for Neisseria gonorrhoeae, 91.5% (43/47) for Chlamydia trachomatis, 71.4% (5/7) for Mycoplasma genitalium, and 100% (13/13) for Ureaplasma urealyticum. The main adverse event was diarrhea and its manifestation rate was 35.2% (32 of 120). The symptom of diarrhea was mostly temporary and resolved spontaneously. The conclusion was that the treatment regimen with a single oral 2 g dose of azithromycin extended-release would be effective for patients with urethritis. However, the antimicrobial susceptibilities of Neisseria gonorrhoeae and Mycoplasma genitalium should be carefully monitored because of possible treatment failure.

ABSTRACT

PURPOSE: To survey the present condition of administration method of the antimicrobial prophylactic (AMP) agents for the perioperative infection in Japan on revising "The Japanese guidelines for prevention of perioperative infections in urologic field (2006)". PATIENTS AND METHODS: With the approval of the Japanese Urological Association (JUA) in 2011, all of the principal urological training institutions certified by JUA (n = 836) were encouraged to participate to survey their adherence to the JUA guidelines (published in 2006) for AMP to prevent perioperative infection in urological field, and 446 (53.3%) institutions responded to the questionnaire. RESULTS: The rates of following the JUA guidelines of, "completely", "mainly", "not too much", and "not at all" were 6.5%, 69.7%, 22.0% and 1.6%, respectively. The guidelines were followed for open clean operations in 48.5%, open clean-contaminated operations in 66.4%, open contaminated operations in 61.8%, laparoscopic clean operations in 54.1%, laparoscopic clean-contaminated operations in 61.2%, transurethral resection of bladder tumor in 71.5%, transurethral resection of prostate in 68.9%, ureteroscopy and transurethral ureterolithotomy in 68.2%, prostate biopsy in 43.2%, and cystoscopy were in 42.2%, respectively. However, in terms of duration of AMP administration, the longer duration than those recommended by the guidelines were observed for clean surgery, transurethral resection of bladder tumor, ureteroscopy and transurethral ureterolithotomy, prostate biopsy, and cystoscopy. CONCLUSIONS: In terms of kinds of AMP, the guidelines were almostly followed in all operative procedures. However, the duration of AMP administration were longer than those recommended by the guidelines. On revision of "Japanese guidelines for prevention of perioperative infections in urologic field (2006)", these data would be taken into consideration to avoid dissociation between the guidelines and the practical side in the urologists.

ABSTRACT

OBJECTIVE: The "Japanese guidelines for prevention of perioperative infections in urological field" was edited by the Japanese Urological Association in 2007. They are the first Japanese guidelines for antimicrobial prophylaxis specifically to prevent perioperative infections in the urological field. We report here the results of a multicenter prospective study conducted to examine the validity and usefulness of these guidelines. PATIENTS AND METHODS: The subjects were 513 patients who had undergone urological surgeries between July and September 2008 at 10 nationwide university institutions in the Japanese Society of UTI Cooperative Study Group. These surgeries were transurethral resection of bladder (TURBT), transurethral resection of prostate (TURP), adrenalectomy, nephrectomy, nephroureterectomy, radical prostatectomy and total cystectomy. Analysis was performed on patient information, surgical procedures, types and durations of administration of prophylactic antibiotic agents, and the presence of surgical site infections (SSI) and remote infections (RI). RESULTS: Of 513 patients, 387 (75.4%) were administered prophylactic antibiotic agents according to the guidelines. In these patients, the incidences of SSI and RI were 5.9% and 4.1%, respectively. Multivariate analysis showed that significant factors for SSI were the surgical risk (according to the ASA physical status classification system), diabetes, and operation time, and that the only significant factor for RI was the operation time. CONCLUSIONS: More large-scale study and evidences are necessary in order to demonstrate the validity and usefulness of these guidelines.

ABSTRACT

Radical cystectomy followed by urinary diversion or reconstruction (RC) is a standard treatment for patients with muscle-invasive bladder cancer. In these operations, a high frequency of complications, especially postoperative infection, has been reported. However, there have only been a few studies about postoperative anaerobic bacterial infection. To clarify the significance and role of anaerobic bacteria in postoperative infection, we retrospectively analyzed cases in which postoperative infection by these organisms developed. A total of 126 patients who underwent RC from 2006 to 2010 were included in this study. Various types of postoperative infection occurred in 66 patients. Anaerobic bacterial infections were detected with cultures for urine and blood in one case, for blood in two cases, and for surgical wound pus in four. The frequency of postoperative anaerobic bacterial infection in RC was less than that of colon surgery. However, this study revealed the possible development of a nonnegligible number of postoperative anaerobic bacterial infections. Therefore, we should consider anaerobic bacteria as possible pathogens in postoperative infection after RC.

ABSTRACT

The spread of antimicrobial-resistant Neisseria gonorrhoeae worldwide is a critical issue in the control of sexually transmitted infections. The purpose of this study was to clarify recent trends in the susceptibility of N. gonorrhoeae to various antimicrobial agents and to compare these data with our previous data. Minimum inhibitory concentrations (MICs) of various antimicrobial agents were determined in N. gonorrhoeae strains clinically isolated from male gonococcal urethritis. In addition, amino acid sequencing of penicillin-binding protein (PBP) 2, encoded by the penA gene, was analyzed so that genetic analysis of mosaic PBP 2 could clarify the susceptibility of the strains to cefixime and other cephalosporins. The susceptibility rate for ceftriaxone, cefodizime, and spectinomycin, agents whose use is recommended by the guideline of the Japanese Society of Sexually Transmitted Infections (JSSTI), was 100 %. The susceptibility rates of the strains to penicillin G and ciprofloxacin were lower than those in previous reports. Mosaic PBP 2 structures were detected in 51.9 % of the strains and the MICs of the strains with the mosaic PBP 2 to cefixime were much higher than those of the strains without the mosaic PBP 2. In the clinical situation, the treatment regimen recommended by the JSSTI remains appropriate; however, the susceptibility to cephalosporins should be intensively surveyed because strains with mosaic PBP 2 were commonly detected.

ABSTRACT

A 67-year-old woman diagnosed with pyonephrosis and perinephric abscess because of an impacted urinary stone in the pelvicoureteric junction was admitted to the hospital with a high-grade fever. Although construction of a right nephrostomy for drainage of the abscess improved her general condition, she had a fever again 2 weeks after the initial treatment. Computed tomography revealed a persistent perinephric retroperitoneal abscess and a second drainage procedure was performed. Then, imaging examination revealed fistula formation between the cavity of the perinephric retroperitoneal abscess and the duodenum. The patient received conservative management including percutaneous drainage, discontinuation of oral intake, and antimicrobial chemotherapy. Three days after the second drainage and discontinuation of oral intake, imaging examination revealed complete closure of the fistula. Fistula formation between a perinephric abscess and the duodenum is very rare but a favorable outcome was obtained by our conservative management.

ABSTRACT

After treatment with antimicrobial chemotherapy for the elimination of urinary multidrug-resistant Pseudomonas aeruginosa (MDRP), a 48-year-old man with recurrence of bladder cancer complained of acute onset of dyspnea, and computed tomography revealed multiple nodular lesions in the lung. Candida albicans was isolated from both urinary and blood samples. He was diagnosed as having a septic pulmonary embolism caused by C. albicans. Fungal septic pulmonary embolism is a rare condition; however, we must be cautious about superinfection as a consequence of strong antimicrobial chemotherapy, and understand that the treatment for urinary MDRP is likely to be difficult.
