The genetic and serological characteristics of Escherichia coli isolates from patients with uncomplicated cystitis (UC), complicated cystitis (CC), and complicated asymptomatic bacteriuria (CASB) were determined. Phylogenetic group B2 was predominant in all categories. The prevalences of 14 out of 18 virulence factor genes were similar among the three(More)
OBJECTIVES To determine the relationship between catheter-colonizing bacteria and urinary planktonic bacteria. The significance of catheter-colonizing bacteria for the pathogenesis of urinary tract infection remains unclear, although they are involved in the development of catheter-associated urinary tract infection refractory to antimicrobial chemotherapy.(More)
There is no standard second-line chemotherapy treatment for recurrent or metastatic urothelial cancer (MUC). The purpose of this phase II study was to evaluate the efficacy and toxicity of the three-drug combination of paclitaxel, ifosfamide, and nedaplatin (TIN). Patients with MUC were eligible after treatment failure with methotrexate, vinblastine,(More)
Fluoroquinolones exhibit immunomodulatory effects on monocytes and macrophages, in addition to their bactericidal activities. It remains unknown even whether the quinolones act directly on the prostate. This study was based on the understanding of the molecular mechanisms of the actions of the fluoroquinolones that can be used for the treatment of chronic(More)
The aim of this study was to confirm the clinical efficacy of a single-dose azithromycin (AZM) regimen (1000 mg) for patients with nongonococcal urethritis in real-life practice. The study finally evaluated 55 patients, 42 who were symptomatic and 13 who were asymptomatic, after excluding 40 who visited clinics only once. Sixteen of the symptomatic patients(More)
We report the clinical courses of 3 patients with urinary obstruction who developed acute pyelonephritis caused by multidrug-resistant (MDR) Pseudomonas aeruginosa. Genome fingerprinting was performed to clarify the route of cross-infection, and an imipenem-resistance gene was detected by the polymerase chain reaction (PCR) method. The study included 17(More)
We aimed to determine the safety and efficacy of monthly paclitaxel and carboplatin with oral estramustine phosphate in patients with hormone-refractory prostate cancer (HRPC). Patients with prostate cancer that was progressing despite androgen ablation therapy were treated with i.v. paclitaxel, 175 mg/m2, over 3 h, followed by carboplatin (area under the(More)
OBJECTIVES To compare the surgical invasiveness of laparoscopic adrenalectomy with that of open surgery when the invasiveness is evaluated by the incidence of systemic inflammatory response syndrome (SIRS). METHODS Patients who underwent open adrenalectomy (35 patients) and those who underwent transperitoneal laparoscopic adrenalectomy (35 patients) were(More)
We investigated the induction of interleukin-8 (IL-8) by bacterial lipopolysaccharide (LPS) and peptidoglycan (PGN) in the bladder cancer cell lines T24, 5637, UM-UC-3, and HT1197. T24 and 5637 cells strongly induced IL-8 after stimulation with LPS or PGN in a dose- and time-dependent manner, whereas UM-UC-3 and HT1197 cells did so very weakly. The(More)
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(More)
