Statistical analysis: chi-square test, Fisher's exact test.

Data were expressed as number (%).

UCS: uterine compression suture.

^*Analysis between preservation of uterus and hysterectomy after uterine compression sutures.

^†Analysis between total uterine compression sutures and postpartum hysterectomy.

Data of age, BMI, gravidity, duration of labor, weeks'gestation, admission hemoglobin were expressed as mean (range).

Data of nulliparity, mode of delivery, induction of labor, multiple pregnancy were expressed as number (%).

BMI: body mass index, Hb: hemoglobin.

^*P<0.005 compared with uterine compression sutures by Bonferroni and Tukey analyses.

^†P<0.05 compared with uterine compression sutures by Bonferroni and Tukey analyses.

^‡P<0.005 between postpartum hysterectomy and hysterectomy after compression sutures by Bonferroni and Tukey analyses.

Data of operative time, EBL, number of packed RBC were expressed as mean (range).

Data of methods of anesthesia, transfusion were expressed as number (%).

EBL: estimated blood loss, RBC: red blood cell.

^*P<0.005 compared with uterine compression sutures by Bonferroni and Tukey analyses.

^‡There were 6 cases with bladder laceration and the operative indications were adhesive placenta in 4 women and placenta previa in 2 women. One case of ureteral injury complained left flank pain at three days after cesarean hysterectomy and showed left hydronephrosis due to distal ureteral obstruction. She had undergone abdominal re-exploration for release of ureteral obstruction.
