Treatment Overview
Sonohysterography (Saline Infusion Sonography) is a minimally invasive imaging procedure used to evaluate the uterine cavity and endometrial lining by introducing sterile saline into the uterus while performing a transvaginal ultrasound. This creates a clear, detailed view of the uterine structure, helping detect abnormalities that might contribute to recurrent pregnancy loss (RPL) or infertility.
In Korea, sonohysterography is a cornerstone diagnostic tool in fertility clinics and women’s hospitals. Korean specialists use high-resolution 3D ultrasound systems, advanced Doppler imaging, and pain-minimizing infusion techniques to obtain precise and comfortable evaluations. It is often part of a broader fertility diagnostic workup that includes hormonal, genetic, and immunologic assessments.
Purpose & Benefits
The primary purpose of sonohysterography is to identify structural uterine abnormalities that may interfere with embryo implantation or increase miscarriage risk.
Key benefits include:
- Detects uterine polyps, fibroids, septa, adhesions, or scarring (Asherman’s syndrome).
- Evaluates the endometrial thickness and uniformity, crucial for implantation success.
- Provides a clearer view than standard ultrasound, without radiation exposure.
- Offers a less invasive alternative to hysteroscopy while still providing high diagnostic accuracy.
- Helps guide treatment planning for surgical correction or fertility optimization.
- Can be combined with 3D reconstruction imaging for enhanced anatomical visualization.
Korean fertility centers favor sonohysterography as a safe, accurate, and cost-effective first-line diagnostic test for uterine evaluation in RPL cases.
Ideal Candidates
Sonohysterography is recommended for:
- Women with two or more recurrent miscarriages of unexplained cause.
- Patients with irregular uterine bleeding or suspected endometrial disorders.
- Individuals with abnormal findings on a standard pelvic ultrasound.
- Women with failed IVF or embryo implantation despite good-quality embryos.
- Patients with history of uterine surgery, infection, or scarring.
- Women preparing for assisted reproductive treatments like IVF or IUI.
This test is typically scheduled during the early follicular phase of the menstrual cycle (days 6–11), after menstruation but before ovulation.
Possible Risks & Complications
Sonohysterography is a safe outpatient procedure, but minor side effects may occur:
- Mild pelvic cramping during or after saline infusion.
- Temporary spotting or watery discharge for a few hours.
- Rare infection or allergic reaction to the saline solution.
- Very rare risk of uterine perforation if performed during pregnancy (hence pre-cycle timing is essential).
Korean clinics minimize these risks using sterile, single-use catheters, gentle infusion techniques, and ultrasound-guided precision performed by experienced reproductive imaging specialists.
Techniques & Imaging Methods Used
Korean fertility centers use advanced imaging protocols and technologies for optimal diagnostic accuracy:
- 2D Sonohysterography: Saline is infused through a thin catheter, and real-time ultrasound monitors uterine cavity contours.
- 3D Sonohysterography: Provides a volumetric reconstruction of the uterus, allowing visualization of complex structural anomalies (e.g., uterine septum).
- Color Doppler Integration: Evaluates uterine blood flow and vascularity, useful in assessing endometrial receptivity.
- Contrast-Enhanced Sonohysterography (HyCoSy): Uses specialized contrast agents to simultaneously assess tubal patency.
- AI-Assisted Image Analysis (in select Korean centers): Advanced algorithms enhance diagnostic precision and report generation.
Korea’s use of cutting-edge ultrasound systems from global medical manufacturers ensures exceptional image clarity and diagnostic reliability.
Recovery & Aftercare
Recovery after sonohysterography is fast and uncomplicated:
- Most patients return to normal activities immediately.
- Mild cramping or spotting may occur for a few hours post-procedure.
- Over-the-counter pain relievers (like ibuprofen) may be used if needed.
- Patients are advised to avoid sexual intercourse, tampons, or douching for 24–48 hours.
- Follow-up with the doctor usually occurs within a few days to discuss results and next steps.
Korean clinics ensure post-procedure comfort with personalized aftercare and same-day result explanations.
Results & Longevity
- The test provides high-resolution imaging of uterine shape, lining, and cavity anomalies.
- Findings such as fibroids, polyps, septa, or adhesions can be immediately correlated with miscarriage risk.
- Abnormalities can then be treated surgically (via hysteroscopy) or medically, depending on findings.
- A normal result gives strong reassurance of uterine integrity.
- Results remain valid for future fertility planning unless major uterine changes occur (e.g., surgery or pregnancy).
Korean centers often integrate results into a multidisciplinary fertility conference, combining inputs from reproductive endocrinologists, surgeons, and radiologists for personalized treatment planning.
Treatment Process in Korea
A typical sonohysterography procedure in Korea follows these steps:
- Initial Consultation: Review of miscarriage history, menstrual cycle timing, and prior imaging.
- Preparation: Performed 1 week after menstruation; a mild pain reliever may be recommended beforehand.
- Procedure:
- A speculum is inserted, and a sterile catheter is placed into the uterus.
- Sterile saline is slowly infused while ultrasound images are taken.
- The procedure lasts about 15–30 minutes.
- Analysis: The physician reviews real-time images and records findings.
- Result Discussion: Immediate feedback is given, with detailed follow-up or treatment recommendations if anomalies are detected.
Why Korea is a Top Destination:
- Advanced 3D and contrast-enhanced imaging systems for superior diagnostic detail.
- Painless and efficient procedures performed by skilled fertility radiologists.
- Integration of reproductive endocrinology, gynecologic imaging, and surgery in one facility.
- High-quality care and rapid turnaround time for results.
- Cost-effective pricing compared to Western fertility clinics.
Korea’s medical infrastructure and focus on precision diagnostics make it a global leader in reproductive imaging and fertility care.
Cost Range
The cost of Sonohysterography in Korea varies depending on the imaging method and clinic:
- Standard 2D Sonohysterography: USD 150 – 300
- 3D or Color Doppler Sonohysterography: USD 300 – 600
- Contrast-Enhanced Sonohysterography (HyCoSy): USD 400 – 700
- Comprehensive RPL Imaging Package (HSG + Sono + Consultation): USD 800 – 1,500
Many Korean fertility hospitals include this test within recurrent pregnancy loss diagnostic bundles, offering efficient and affordable evaluations.
