Hysterectomy, the most common major nonobstetric operation, is performed in more than 570,000 women in the United States each year. Although the number of hysterectomies has decreased in recent years, many authorities believe that hysterectomy is often unnecessary and unjustified. There is no universally accepted set of criteria regarding the appropriate indications for hysterectomy. The main indications for hysterectomy include the following conditions: uterine leiomyomas, dysfunctional uterine bleeding, endometriosis/adenomyosis, chronic pelvic pain and genital prolapse. Current literature, however, routinely recommends conservative management of most nonmalignant gynecologic conditions, with hysterectomy reserved for refractory cases. Several nonmedical factors, such as patient race, age, geographic location, medical history and background, as well as health care provider characteristics, such as time since completion of training, gender, and affiliation with teaching hospitals, are also associated with hysterectomy rates.
