Gel instillation sonohysterography: first experience with a new technique.

Area of Science:

• Gynecological imaging
• Medical device technology
• Ultrasound diagnostics

Background:

• Sonohysterography is crucial for evaluating uterine cavity abnormalities.
• Traditional saline infusion can be challenging for stable distension.
• Improving visualization techniques is essential for accurate diagnosis.

Purpose of the Study:

• To evaluate a novel gel instillation technique for artificial uterine cavity distension.
• To simplify and enhance sonohysterography procedures.
• To compare gel instillation with conventional saline infusion.

Main Methods:

• Prospective observational study involving 120 patients.
• Instillation of hydroxyethylcellulose gel with anesthetic and antiseptic agents.
• Concomitant transvaginal 3D ultrasonography for real-time imaging.

Main Results:

• Optimal uterine cavity distension achieved in 113 patients using an average of 4 mL of gel.
• Stable filling allowed precise visualization of uterine lining and structures.
• The technique provided an optimal presentation for 3D ultrasound reconstruction.

Conclusions:

• Gel instillation is a simple and minimally inconvenient method for sonohysterography.
• This technique offers an attractive alternative to saline infusion.
• Improved visualization enhances diagnostic accuracy in gynecological evaluations.
