Because of the increasing bacterial resistance of uropathogens against standard antibiotics, such as trimethoprim (TMP), older antimicrobial drugs, such as nitroxoline (NTX), should be reevaluated. This randomized crossover study investigated the urinary concentrations of parent drugs and their metabolites and their antibacterial activities (urinary inhibitory titers [UITs] and urinary bactericidal titers [UBTs]) against uropathogens at three different urinary pH values within 24 h in six healthy volunteers after a single oral dose of NTX at 250 mg versus TMP at 200 mg. In three additional volunteers, urinary bactericidal kinetics (UBK) were studied after oral administration of NTX at 250 mg three times a day.

Methods: Urinary concentrations and urinary bactericidal titers (UBT) of finafloxacin 200- and 800-mg single doses in 6 healthy volunteers were measured up to 48 h. UBT were determined for a reference strain and 9 selected clinical uropathogens at the pH of native, acidified (pH 5.
Introduction: Benign prostatic hyperplasia (BPH) may ultimately result in acute urinary retention (AUR). This study was performed to assess the impact of transurethral resection of the prostate (TURP) on urodynamic parameters in patients with BPH using pre- and postoperative pressure-flow studies (PFS) and compare those between patients with and without preoperative AUR.
Patients And Methods: 78 patients underwent TURP because of symptoms due to BPH and were evaluated preoperatively and at follow-up after a mean ± SD of 27 ± 11.
Objective: Uncomplicated cystitis in women is among the most frequent infections in the community setting. The German results of the international ARESC Study are reported concerning clinical aspects, epidemiology, and antimicrobial susceptibility of uropathogens.
Patients And Methods: Patients between 18 and 65 years of age with symptoms of uncomplicated cystitis were consecutively enrolled and investigated clinically including urinalysis and urine culture.
The aim of this study was to investigate the urinary bactericidal titers (UBTs) and 24-h area under the UBT-versus-time curve (AUBT) of intravenous doripenem (500 mg every 8 h [q8h]), a new carbapenem, versus those of intravenous levofloxacin (250 mg q24h) in patients with complicated urinary tract infections (cUTIs) or pyelonephritis. UBTs and AUBTs are pharmacokinetic/pharmacodynamic parameters able to reflect the activity of an antimicrobial substance in the urine. Doripenem and levofloxacin show comparable urinary excretion of approximately 80% and are therefore registered for the treatment of UTIs.
