title: Prevalence of hysteroscopic findings and histologic diagnoses in patients with abnormal uterine bleeding.
abstract: OBJECTIVE
  To describe the prevalence of hysteroscopic findings and histologic diagnoses in patients with abnormal uterine bleeding (AUB).
  
  
  METHODS
  Retrospective series of consecutive patients.
  
  
  METHODS
  Tertiary care university hospital and private office.
  
  
  METHODS
  Four thousand fifty-four hysteroscopies with biopsy in patients with AUB evaluated between June 1993 and December 2004.
  
  
  METHODS
  Hysteroscopies were performed using 2.9-mm or 4-mm telescopes with CO(2) or saline as the distension media. Biopsies were done with a 5-mm grasper or with a Novak's curette.
  
  
  METHODS
  Prevalence of hysteroscopic findings and histologic analysis of biopsies.
  
  
  RESULTS
  Endometrial polyp was the most frequent hysteroscopic finding, accounting for 1,374 (33.9%) cases. Normal uterine cavity and cervical canal were found in 814 (20.1%) patients. Submucous fibroids were diagnosed in 302 (7.5%) women. Normal endometrium was the most frequent histologic diagnosis, accounting for 1,888 (46.6%) cases. Endometrial polyp was found in 1,115 (27.5%) patients. Endometrial hyperplasia was diagnosed in 613 (15.1%) and endometrial cancer in 105 (2.6%) women.
  
  
  CONCLUSIONS
  Endometrial polyps are the most frequent hysteroscopic findings in patients with AUB, whereas normal endometrium is the most frequent histologic diagnosis.
