Objective:
A practical attempt to simplify and improve the technique of artificial uterine cavity distension by instilling gel instead of flushing saline.
Design:
Prospective observational study.
Setting:
Teaching hospital.
Patient(S):
One hundred twenty patients with an indication for sonohysterography (abnormal uterine bleeding, exclusion of congenital abnormalities, or preoperative or postoperative evaluation of submucous myomas, polyps, or synechiae).
Intervention(S):
A hydroxyethylcellulose gel containing anesthetic and antiseptic agents was instilled in the uterine cavity through a plastic intrauterine insemination cannula attached to a flexible plastic tube and a syringe. Transvaginal (3-dimensional) ultrasonography was performed concomitantly.
Main Outcome Measure(S):
Stable filling of the uterine cavity allowing a high-quality ultrasonographic visualization.
Result(S):
An optimal distension of the uterine cavity could be achieved with an average of only 4 mL (range, 2-10 mL) in 113 patients. As expected, a stable filling of the uterine cavity permitted a precise visualization of the uterine cavity and its linings and offered an optimal presentation for a 3-dimensional ultrasound recording and reconstruction.
Conclusion(S):
Gel instillation is a simple technique with minimal inconvenience for the patient and seems to be an attractive alternative to saline infusion during sonohysterography.
