๐ก C-Section Niche (Isthmocele): A Hidden Cause of Post-Cesarean Symptoms
A C-section niche also called an isthmocele is a small pouch or defect that forms at the site of a previous cesarean-section scar within the uterine wall.
It occurs when the myometrial layer doesn’t heal completely, leaving a thin or recessed area along the scar.
๐ฌ Why It Happens
Incomplete healing of the uterine incision
Infection or inflammation during recovery
Multiple cesarean sections.
Closure technique or suturing method
A very thin lower uterine segment at the time of surgery.
⚠️ Possible Symptoms
-Spotting or brown discharge after menstruation.
-Pelvic pain or a feeling of heaviness
-Difficulty conceiving (secondary infertility)
-Rarely, scar pregnancy or abnormal implantation.
๐ฉบ Diagnosis
Usually detected by:
-Transvaginal ultrasound (TVS)
-Saline infusion sonography (SIS) for better visualization
-Sometimes confirmed by hysteroscopy if intervention is planned.
๐ Management
Depends on the size and symptoms:
Observation if asymptomatic
Hormonal therapy to regulate bleeding
Hysteroscopic repair for small defects
Laparoscopic or combined repair for larger niches causing infertility.
✅ Key Message
C-section niche is not rare it’s just under-diagnosed.
Every woman with unexplained spotting, pelvic pain, or infertility after cesarean delivery should be evaluated for this condition.
Early detection prevents chronic discomfort and improves reproductive outcomes.
