Objective To probe into the clinical feature of hysteroscopy in the diagnosis and treatment of abnormal uterine bleeding and to summarize its clinical value.Method Clinical data of 68 cases of patients with abnormal uterine bleeding who had been diagnosed and treated with hysteroscopy in our hospital from october 2007 to october 2009 was statistically analyzed.Results Among the 68 cases of patients with abnormal uterine bleeding

hysteroscopy detected positive lesions in 55 cases with a positive rate of 80.9%.The detection rate of submucous hysteromyoma and incarceration of intrauterine device was the highest with a percentage of 100%

which was remarkably higher than that of endometrial cancer

endometrial polyp

atypical hyperplasia of endometrium

simple endometrial hyperplasia and complex endometrial hyperplasia

and the differences were statistically significant（p<0.05）.For the 55 cases detected

37 cases undergone diagnostic hysteroscopy and curettage

11 cases hysteroscopic electrosurgery and 7 cases hysterectomy

and no case was recurred after one year follow-up.Conclusion Hysteroscopy has a high positive rate in diagnosing abnormal uterine bleeding and it has less bleeding and clear vision during operation and can conserve fertility used for treating abnormal uterine bleeding

which also has the advantages of minimal trauma

quick recovery

short hospitalization time and low recurrent rate

therefore it is preferred to treat abnormal uterine bleeding caused by intrauterine benign lesions.
