Prevalence of cystic paraurethral structures in asymptomatic women at endovaginal and perineal sonography

AIM: To prospectively assess the prevalence of paraurethral cystic structur es in asymptomatic adult women. PATIENTS AND METHODS: One hundred and forty consecutive women undergoing en dovaginal sonography with no history of lower urinary tract symptoms. RESULTS: Paraurethral cystic structures were identified in 4140 subjects (2 .9%). Ultrasound assessment allowed rapid definition of the site, size and vascularity of these lesions and was well tolerated by the patient. CONCLUSION: This is the first prospective ultrasound study to determine the pre-valence of paraurethral cystic structures in a large consecutive cohor t of asymptomatic women. Our findings are in accordance with previously pub lished post-mortem data and surgical series which have estimated the preval ence of paraurethral cystic structures to be between 1 and 6%. Cross, J.
