Changes in rates of hysterectomy and uterine conserving procedures for treatment of uterine leiomyoma

Abstract

Objective: The purpose of this study was to investigate treatment of uterine leiomyoma by hysterectomy and uterine conserving procedures (UCPs).

Study design: Data from Kaiser Permanente Northern California members undergoing hysterectomy, myomectomy, uterine artery embolization (UAE) and endometrial ablation (EA) for uterine leiomyoma from 1997-2003 were collected. Statistical analysis included trend tests and survival analysis.

Results: Hysterectomy rates for leiomyoma decreased significantly from 2.13 per 1000 to 1.91 (P < .0001). Rates for myomectomy (.4-.37) and EA (.26-.27) remained stable (P = .17 and .26, respectively), whereas rates for UAE increased significantly from < .01-.24 (P < .0001). The combined rates for hysterectomy and UCPs remained stable at 2.79 (P = .95). Rate of hysterectomy after UCP increased over time, and at 6 years reached 11.5%, 17.7%, and 7.9% for EA, UAE, and myomectomy, respectively.

Conclusion: Whereas rate of hysterectomy for leiomyoma decreased, total rate of invasive treatment remained stable. Increase in rate of UAE had the greatest impact on treatment, possibly replacing hysterectomy.
