Hysterectomy prevention using the uterine hollow obliterations (HYUNHO) method for placenta previa
1Department of Obstetrics and Gynecology, Soonchunhyang University Bucheon Hospital, Bucheon, Republic of Korea.
Objective:
We have invented a method of hysterectomy prevention called the uterine hollow obliteration (HYUNHO) method to preserve the uterus and fertility after treating placenta previa or accreta.
Methods:
Eighty patients underwent cesarean section because of placenta previa between January 2003 and December 2009. All patients eligible for the study were evaluated by followup and a telephone questionnaire about fertility, menstruation recovery, and complications.
Results:
The success rate on preserving the uterus with the HYUNHO method was 96.2%. Three cases required additional procedures, including a cesarean hysterectomy or uterine artery embolization (UAE), two cases underwent a cesarean hysterectomy after delivery, and one case underwent UAE.
Conclusion:
The HYUNHO method is a safe, easy method for placenta previa, although it should be evaluated in a randomized controlled trial.
