title: Prevalence and treatment efficacy of genitourinary mycoplasmas in women with overactive bladder symptoms.
abstract: OBJECTIVE
  To evaluate the incidence of genitourinary mycoplasmas and the efficacy of antibiotics in women with overactive bladder (OAB) symptoms.
  
  
  METHODS
  Women with OAB symptoms (micturition ≥8/24 hours and urgency ≥1/24 hours) for ≥3 months were screened for Mycoplasma hominis (M. hominis), Ureaplasma urealyticum (U. urealyticum), and Chlamydia trachomatis (C. trachomatis). Specimens from urethral and cervical vaginal swabs were examined for M. hominis and U. urealyticum by using the Mycoplasma IST2 kit and for C. trachomatis by using PCR. Women with positive results were treated with a 1 g dose of azithromycin. Persistent infection was treated with doxycycline. Changes in a 3-day bladder diary, Patient Perception of Bladder Condition (PPBC), and International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptoms (ICIQ-FLUTS) were evaluated 4 weeks after negative conversion. Patient satisfaction was assessed.
  
  
  RESULTS
  Of 84 women screened, 42.8% were positive (U. urealyticum, 40.5%; M. hominis, 7.1%; C. trachomatis, 3.6%; two organisms, 8.3%). After treatment, 82.7% obtained negative conversion, and their median number of micturition episodes decreased from 10.6/24 hours to 8.1/24 hours (p=0.002). PPBC and domain scores of the ICIQ-FLUTS (filling and quality of life) significantly improved. About 87.5% women with negative conversion were satisfied with the treatment.
  
  
  CONCLUSIONS
  Considering diagnostic tests and treatment for genitourinary mycoplasmas might be beneficial before invasive workup or treatment in women with OAB symptoms.
