Uterine Niche

Dr. Raanan Meyer specializes in the accurate diagnosis and minimally invasive surgical treatment of uterine niche, offering personalized care that addresses both symptoms and reproductive goals.

What Is a Uterine Niche?

A uterine niche, also known as an isthmocele or Cesarean scar defect, is a pouch-like defect that develops at the site of a previous C-section incision. This indentation in the lower uterine segment can collect menstrual blood and disrupt the normal function of the uterus. While often overlooked or misdiagnosed, a uterine niche can lead to abnormal bleeding, pelvic pain, and even fertility challenges.

What Causes a Uterine Niche?

Uterine niche formation is most commonly associated with previous Cesarean deliveries. During a C-section, the uterus is incised and sutured. In some cases, this area does not heal evenly or completely, leaving a small defect or indentation.

Contributing factors may include:
  • Multiple C-sections
  • Low uterine incisions
  • Infections or inflammatory responses post-surgery
  • Anatomic variations of the uterus

Although not every woman who has had a C-section will develop a niche, the risk increases with each additional Cesarean delivery.

Symptoms of Uterine Niche

Many patients with a uterine niche are asymptomatic and only discover it during evaluation for another condition. However, for others, the defect can cause persistent and distressing symptoms.
Common symptoms include:
  • Prolonged menstrual bleeding or spotting after periods (postmenstrual spotting)
  • Pelvic pain or cramping
  • Lower abdominal pressure
  • Pain during intercourse (dyspareunia)
  • Infertility or difficulty conceiving
  • Secondary amenorrhea or irregular cycles
  • Recurrent miscarriage or failed embryo implantation

The most classic presentation is light brown or bloody discharge that occurs several days after the end of menstruation, often due to blood pooling in the niche.

How Uterine Niche Affects Fertility

  • A uterine niche can interfere with the normal function of the uterine lining, endometrial receptivity, and cervical mucus clearance. It may act as a physical barrier to sperm transport or embryo implantation. Additionally, fluid trapped in the niche may flow back into the uterine cavity, disrupting embryo development in natural and assisted reproduction cycles.

In women undergoing IVF or fertility treatments, untreated uterine niches are associated with lower implantation rates and increased risk of miscarriage.

How Is a Uterine Niche Diagnosed?

  • Because uterine niches are underdiagnosed, it is essential to see a gynecologic specialist familiar with advanced imaging and surgical evaluation.
Dr. Meyer uses a combination of techniques to identify and assess the depth and severity of the niche:
  • Transvaginal ultrasound with saline infusion (sonohysterography)
  • 3D ultrasound for volumetric imaging of the niche
  • Pelvic MRI to assess associated adhesions or other uterine abnormalities
  • Diagnostic hysteroscopy to visualize the defect from inside the uterine cavity
  • Laparoscopy for direct assessment when needed

The size, depth, and location of the niche help determine the appropriate treatment approach, especially if fertility preservation is a goal.

Minimally Invasive Treatment Options for Uterine Niche

Dr. Raanan Meyer offers state-of-the-art surgical options for treating uterine niche, with a strong emphasis on minimally invasive techniques and fertility preservation.

Hysteroscopic Niche Resection

This is a scarless procedure performed through the cervix, often recommended for small to moderate-sized niches in women who do not desire future pregnancies.

  • No abdominal incisions
  • Same-day outpatient procedure
  • Quick recovery and symptom relief
  • Effective reduction of postmenstrual bleeding

Hysteroscopic niche repair involves removing the fibrotic tissue inside the niche and reshaping the cavity to improve fluid drainage and eliminate residual bleeding.

Laparoscopic or Robotic Niche Repair

For larger or deeper niches—especially in women planning future pregnancies—laparoscopic or robotic repair is the preferred approach. This technique allows for precise excision of the defect, removal of scar tissue, and layered closure of the uterine wall.

Dr. Meyer uses advanced laparoscopic or robotic tools to perform this repair with maximum precision and minimal trauma to the surrounding tissue.

Advantages of laparoscopic/robotic repair:
  • Fertility-preserving
  • Restoration of healthy uterine anatomy
  • Reduced risk of uterine rupture in future pregnancies
  • Improved implantation and live birth outcomes in IVF patients

When Is Surgery Recommended?

You may be a candidate for niche repair if you:

  • Have ongoing abnormal spotting or postmenstrual bleeding
  • Experience pelvic pain or pressure after your period
  • Have had failed IVF cycles or recurrent pregnancy loss
  • Are planning future pregnancy and have a known niche defect
  • Have imaging-confirmed niche with retained menstrual blood

Dr. Meyer performs a full evaluation to determine the most appropriate treatment pathway based on your symptoms, reproductive plans, and overall uterine health.

Recovery and Outcomes

Most minimally invasive niche repairs offer fast recovery and excellent symptom resolution. Patients typically return to work and normal activities within one week, with very low rates of complications.

Studies show that surgical niche correction significantly improves menstrual symptoms, patient satisfaction, and fertility outcomes. For patients with secondary infertility or failed IVF due to fluid buildup in the cavity, niche repair can dramatically increase the chances of a successful pregnancy.
