Complete or incomplete uterine inversion depends on whether fundus has passed through:-
**Core Concept**
Uterine inversion is a rare but serious complication of childbirth where the uterus turns inside out, often requiring immediate medical attention. The type of inversion depends on the extent to which the uterus is inverted.
**Why the Correct Answer is Right**
Complete uterine inversion occurs when the fundus (the upper part of the uterus) passes through the cervix and into the vagina. This is often associated with a more severe inversion, where the uterus is completely inverted. In contrast, incomplete uterine inversion occurs when the fundus only partially passes through the cervix, but not through the vaginal apex. This may be less severe, but still requires prompt medical attention to prevent further complications.
**Why Each Wrong Option is Incorrect**
* **Option A:** Incorrect, as this option does not specify the extent of the inversion or the location of the fundus.
* **Option B:** Incorrect, as this option does not accurately describe the criteria for complete or incomplete inversion.
* **Option D:** Incorrect, as this option is not relevant to the criteria for complete or incomplete uterine inversion.
**Clinical Pearl / High-Yield Fact**
It's essential to recognize the signs of uterine inversion, including severe abdominal pain, vaginal bleeding, and a soft, boggy uterus. Prompt recognition and treatment can prevent long-term complications, such as infertility and recurrent miscarriage.
**Correct Answer: C.**
