BACKGROUND The aim of the present study was to assess the usability and efficacy of our new protocol of prophylactic antibiotic use to prevent perioperative infection in urological surgery. METHODS We prospectively investigated 339 cases of typical urological surgery in our department between April 2001 and March 2002 (group I). We classified surgical(More)
In radical cystectomy (RC), surgical-site infection (SSI) remains one of the most frustrating postoperative complications. Only a few reports have assessed SSI after RC according to the guideline authorized by the Centers for Disease Control and Prevention (CDC guideline). In this study, using the guideline, we assessed the incidence, causative organisms,(More)
The aim of this study was to estimate the incidence rates of asymptomatic sexually transmitted infections (STI) in young men in Sapporo, Japan. A survey of 204 healthy male volunteers was conducted. First-voided urine specimens were used for detection of Chlamydia trachomatis and Neisseria gonorrhoeae with polymerase chain reaction assay, and cotton swab(More)
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)
PURPOSE To evaluate the clinical impact on progression and recurrence according to presence and absence of a muscle layer, we conducted a retrospective, multicenter study. METHODS We retrospectively reviewed 247 patients who received transurethral resection (TUR) of bladder tumors and were pathologically diagnosed as having T1G3 bladder cancer from 1990(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)
An adequate protocol for antimicrobial prophylaxis (AMP) in radical prostatectomy has not been established. We retrospectively compared the incidence and severity of infectious complications after radical prostatectomy with three different protocols for AMP. The study cohort consisted of 67 patients with prostate cancer who underwent radical prostatectomy(More)
Surgical site infection (SSI) remains an important cause of morbidity among hospitalized patients. We reviewed 421 patients who underwent open urological operations between January 1993 and December 1997 in our institute. Group I consisted of 259 patients who received uncontrolled antimicrobial prophylaxis (AMP) between 1993 and 1995. Group II consisted of(More)
BACKGROUND We evaluated the relationship between serum PSA and clinical variables to eliminate bone scanning in patients with prostate cancer having a low probability of bone metastasis. METHODS The study included 366 patients with newly diagnosed prostate cancer between 1999 and 2005. Bone metastasis was studied for its correlation with various clinical(More)
BACKGROUND The roles of Toll-like receptor 2 (TLR2) and Mycoplasma in prostate inflammation remain unclear. We investigated whether Mycoplasma induced inflammatory cytokine secretion through TLR2-mediated mechanism in prostate cancer cell line. METHODS Cell surface expression of TLR2 on PC-3 cells were examined by flowcytometry. PC-3 cells were stimulated(More)
