Which statement about the Kronig incision is true?

• A. It is an 8 cm vertical incision in the lower uterine segment after the bladder is separated and retracted
• B. It is a transverse incision in the lower uterine segment
• C. It is a vertical incision in the upper uterine segment
• D. It is used only in vaginal hysterectomy

Answer: (A)

The Kronig incision is a vertical opening in the lower uterine segment, about 8 cm in length, made after the bladder has been separated and retracted to protect it. This placement in the lower segment, combined with a vertical orientation, provides rapid access for cesarean delivery and enough space for fetal extraction while minimizing bladder injury.

It is not a transverse incision, it is not located in the upper uterine segment, and it is not restricted to vaginal hysterectomy.
