	Ligation group (n = 48)	Control group (n = 56)	p value
• Preoperative Hb (g/dL)	11.1 ± 0.61	11.2 ± 0.6	0.6
• Postoperative Hb (g/dL)	10.2 ± 0.34	9.3 ± 0.56	0.0001*
• Intraoperative blood loss (mL)	569.3 ± 202.1	805.1 ± 224.5	0.0001*
• Operative time (min)	54.2 ± 11.2	57 ± 10.9	0.2
• Amount of blood transfusion (mL)	755 ± 56	786 ± 83	0.03*
• Further surgical interventions:	0	3 (5.4%)
➢ IIA ligation	0	2 (3.6%)	0.001*
➢ Supravaginal hysterectomy	0	1 (1.8%)	0.001*
• Urinary bladder injury	1 (2.1%)	2 (3.6%)	0.2
• Bleeding from varicosities over bladder surface	2 (4.2%)	3 (5.4%)	0.6
• Postpartum hemorrhage (n)	0	2 (3.6%)	0.02*

12 cases were excluded from ligation group in the final analysis due failure of the procedure. Results remained significant by comparing 56 patients in the control group versus 60 patients in the ligation group
