Question 1

What is the Meaning of Saline Infusion Sonohysterography?

Accepted Answer

Saline Infusion Sonohysterography (SIS) is a specialized gynecological imaging technique. It uses transvaginal ultrasound after sterile saline is instilled into the uterine cavity. This enhances visualization of the endometrial lining and internal uterine contours, allowing precise identification of structural anomalies. The fluid distends the cavity, acting as an acoustic contrast medium to improve image clarity.

Question 2

What is the Context of Saline Infusion Sonohysterography?

Accepted Answer

Within reproductive medicine, SIS is a crucial diagnostic tool for assessing the uterine cavity when conventional transvaginal ultrasound is inconclusive. It serves as a second-line investigation for conditions affecting the endometrium and myometrium, vital female reproductive components. This technique integrates into diagnostic pathways for various gynecological concerns, offering clearer understanding of the uterine environment.

Question 3

What is the Significance of Saline Infusion Sonohysterography?

Accepted Answer

The significance of SIS lies in its capacity to improve diagnostic accuracy for uterine pathologies, directly influencing patient management and health outcomes. By providing detailed visualization of the endometrial cavity, this procedure aids in pinpointing causes of abnormal uterine bleeding, infertility, and recurrent pregnancy loss. Accurate diagnosis allows clinicians to formulate targeted treatment plans, potentially avoiding invasive surgical interventions.

Question 4

What is the Mechanism of Saline Infusion Sonohysterography?

Accepted Answer

The mechanism of SIS relies on fluid distension within the uterine cavity to optimize ultrasound imaging. A catheter is inserted through the cervix, introducing sterile saline. This fluid expands the endometrial space, separating uterine walls. The anechoic saline allows ultrasound waves to pass unimpeded, creating stark contrast against endometrial or submucosal lesions, enhancing visibility and enabling accurate differentiation.

Question 5

What is the Application of Saline Infusion Sonohysterography?

Accepted Answer

SIS finds widespread application for evaluating the uterine cavity in women with gynecological concerns. It is routinely employed in fertility clinics to assess structural impediments to conception, including endometrial polyps, submucosal fibroids, or intrauterine adhesions. The procedure also investigates abnormal uterine bleeding, distinguishing between hormonal and structural abnormalities. It serves as a valuable pre-procedural assessment for assisted reproductive technologies.

Question 6

What is the Metric of Saline Infusion Sonohysterography?

Accepted Answer

Assessment from SIS is qualitative and quantitative, focusing on visual characteristics and dimensions of identified uterine abnormalities. Clinicians evaluate endometrial stripe thickness and regularity, noting the presence, size, and location of focal lesions like polyps or submucosal fibroids, providing precise millimeter measurements. Uterine cavity distension, fallopian tube patency, and intrauterine adhesions are meticulously documented, forming a comprehensive report.

Question 7

What is the Risk of Saline Infusion Sonohysterography?

Accepted Answer

While generally a safe outpatient procedure, SIS carries potential risks and contraindications. Patients may experience mild to moderate cramping during or shortly after, with light vaginal spotting. Although rare, a minimal infection risk exists, necessitating aseptic technique. The procedure is strictly contraindicated in cases of known or suspected pregnancy, active pelvic inflammatory disease, or acute cervical infection, as these could lead to adverse outcomes.
