(Introduction)HoLEP's role in the surgical management of benign prostatic hyperplasia (BPH) is steadily growing. In this study, a questionnaire containing questions about perioperative management was submitted to HoLEP surgeons to help establish standard surgical training procedures. (Methods)We sent a comprehensive 17 questionnaires on HoLEP procedures to 18 surgeons.

The antimicrobial susceptibility patterns of bacterial pathogens isolated from patients with complicated urinary tract infections were analyzed using national surveillance data. The data consisted of 881 bacterial strains from eight clinically relevant species. The data were collected for the third national surveillance project from January 2015 to March 2016 by the Japanese Society of Chemotherapy, the Japanese Association for Infectious Disease, and the Japanese Society of Clinical Microbiology.

Article Synopsis
  • A nationwide surveillance study conducted in Japan from April 2009 to November 2010 examined antimicrobial susceptibility patterns of uropathogens causing acute uncomplicated cystitis in women, involving 43 hospitals.
  • The study identified E. coli as the most common bacteria (77.8%) in urine samples, with significant occurrences of S. saprophyticus in premenopausal women, while also analyzing their resistance to 19 antimicrobial agents.
  • Results indicated high susceptibility of E. coli to fluoroquinolones and cephalosporins, but a rising trend in fluoroquinolone-resistant and ESBL-producing strains highlights the need for careful selection of empirical treatments based on patient characteristics.
