Uterine Niche

A uterine niche is a defect in the myometrium at the site of a previous cesarean section scar. It is also known as a cesarean scar defect or isthmocele. This condition can lead to various gynecological symptoms and complications, including abnormal uterine bleeding, pelvic pain, and secondary infertility.

Anatomy and Pathophysiology

The uterine niche is typically located at the lower segment of the uterus, where the cesarean section incision was made. The defect occurs when the myometrial tissue does not heal properly, resulting in a pouch or indentation. This can cause the endometrial lining to become trapped, leading to the accumulation of menstrual blood and other symptoms.

Clinical Presentation

Patients with a uterine niche may present with:

Abnormal uterine bleeding, particularly postmenstrual spotting
Pelvic pain
Dysmenorrhea
Dyspareunia
Secondary infertility

Diagnosis

The diagnosis of a uterine niche is typically made using imaging techniques such as:

These imaging modalities can help visualize the defect and assess its size and depth.

Treatment

Treatment options for a uterine niche depend on the severity of symptoms and the patient's reproductive plans. They may include:

Hysteroscopic surgery to resect the niche
Laparoscopic surgery for more extensive repair
Hormonal therapy to manage symptoms

Prognosis

The prognosis for patients with a uterine niche varies. Surgical repair can alleviate symptoms and improve fertility outcomes, but the success rate depends on the size and location of the niche.

-A '''uterine niche''' is a defect or indentation in the uterine wall at the site of a previous [[cesarean section]] scar. It is a condition that can affect women who have undergone a cesarean delivery, and it may have implications for future pregnancies and gynecological health.

-The formation of a uterine niche is primarily associated with the healing process of the uterine incision made during a cesarean section. Factors that may contribute to the development of a niche include the surgical technique used, the number of previous cesarean sections, and the individual's healing response. Inadequate healing of the uterine scar can lead to the formation of a niche.
