|Risk of Hysterectomy Following Uterine Rupture
The risk of hysterectomy (Cesarean Hysterectomy, C-Hyst) is lower with TOLAC compared to ERCS (157 versus 280 per 100,000 respectively) and may be lower in women at term. However, when a uterine rupture occurs, the percentage of women requiring C-Hyst is between 14-33%.
Limited evidence suggests that the risk of C-Hyst increases with induction of labor, high-risk pregnancy, and increasing number of cesarean deliveries:
- One previous C/S: 420:100,000 (0.42%)
- Two previous C/S: 900:100,000 (0.9%)
- Three previous C/S: 2410: 100,000 (2.41%)
- Four previous C/S: 3,490: 100,000 (3.49%)
- Five previous C/S: 8,990: 100,000 (8.99%)
