title: Sonohysterography in premenopausal women with and without abnormal bleeding.
abstract: OBJECTIVE
  To estimate the prevalence of abnormalities detected by sonohysterography in premenopausal women who were asymptomatic or had abnormal uterine bleeding.
  
  
  METHODS
  Standard sonohysterography was done in 100 asymptomatic premenopausal women age 30 and older. The prevalence of uterine abnormalities was recorded and compared with findings in 80 premenopausal women evaluated in our unit for abnormal uterine bleeding.
  
  
  RESULTS
  Compared with asymptomatic women, premenopausal women with abnormal uterine bleeding had a higher prevalence of polyps (33 versus 10%), intracavitary myomas (21 versus 1%), and intramural myomas (58 versus 13%). Ten percent of asymptomatic women had polyps, but these polyps tended to be smaller than the polyps found in women with abnormal bleeding (8.5 versus 13.9 mm, P = .064). Polyps were associated significantly with myomas, and both were more common in older premenopausal women.
  
  
  CONCLUSIONS
  Intracavitary lesions and intramural myomas are more prevalent in women with abnormal uterine bleeding than in asymptomatic women, suggesting a causative relationship. However, small endometrial polyps are common and frequently asymptomatic.
