Uterine Rupture Most Common After Classical Cesarean

Uterine rupture is a rare but severe complication where the uterus tears. The risk is significantly higher following certain surgical procedures, particularly those involving incisions in the main body of the uterus.

Surgical Procedure Analysis for Uterine Rupture Risk

Evaluating the options provided:

• Classical cesarean: This involves a vertical incision in the upper, thicker part of the uterus. This type of incision has a higher risk of rupture in subsequent pregnancies or labors compared to other types of cesarean incisions. It is the most common risk factor among the choices given.
• Metroplasty: This surgery reshapes the uterus, often for malformations. While it involves uterine surgery, it is not typically associated with the same high risk of rupture as a classical cesarean incision.
• Myomectomy: This procedure removes uterine fibroids. Depending on the size, location, and depth of the fibroid removal, there can be a risk of rupture, but it is generally considered lower than the risk associated with a previous classical cesarean.
• Hysterotomy: This is a general term for a surgical incision into the uterus. A classical cesarean section includes a classical hysterotomy. If the term is used independently, it refers to the incision itself. However, the context of a "classical cesarean" points specifically to the procedure type most linked to rupture risk.

Conclusion: Based on surgical history, a previous classical cesarean section presents the highest risk for subsequent uterine rupture compared to metroplasty or myomectomy.
