title: Prevalence of cystic paraurethral structures in asymptomatic women at endovaginal and perineal sonography.
abstract: OBJECTIVE
  To prospectively assess the prevalence of paraurethral cystic structures in asymptomatic adult women.
  
  
  METHODS
  One hundred and forty consecutive women undergoing endovaginal sonography with no history of lower urinary tract symptoms.
  
  
  RESULTS
  Paraurethral cystic structures were identified in 4/140 subjects (2.9%). Ultrasound assessment allowed rapid definition of the site, size and vascularity of these lesions and was well tolerated by the patient.
  
  
  CONCLUSIONS
  This is the first prospective ultrasound study to determine the prevalence of paraurethral cystic structures in a large consecutive cohort of asymptomatic women. Our findings are in accordance with previously published post-mortem data and surgical series which have estimated the prevalence of paraurethral cystic structures to be between 1 and 6%.
