Contrast ultrasonography for tubal patency

Area of Science:

• Reproductive Medicine
• Diagnostic Imaging
• Gynecology

Background:

• Tubal patency assessment is crucial for fertility evaluations.
• Laparoscopy with chromopertubation and hysteroscopy are considered the gold standard.
• There is a need for minimally invasive and accurate diagnostic methods.

Purpose of the Study:

• To review hysterosalpingo-contrast sonography (HyCoSy) as a newer diagnostic tool.
• To compare the accuracy of HyCoSy with established methods for evaluating tubal patency and uterine cavity.
• To assess patient preference for HyCoSy in an office setting.

Main Methods:

• Review of existing literature on HyCoSy.
• Comparison of HyCoSy accuracy against laparoscopic chromopertubation and hysterosalpingography (HSG).
• Inclusion of saline solution-enhanced sonohysterography for uterine cavity evaluation.

Main Results:

• HyCoSy demonstrates accuracy comparable to HSG for tubal patency (sensitivity 75-96%, specificity 67-100%).
• HyCoSy accurately identifies tubal occlusion post-sterilization, with high patient preference for in-office procedures.
• Saline-enhanced sonohysterography component of HyCoSy shows >90% accuracy for uterine cavity evaluation.

Conclusions:

• HyCoSy is a minimally invasive, well-tolerated method for fertility workup.
• HyCoSy offers high accuracy for both tubal patency and uterine cavity assessment.
• HyCoSy is a potential replacement for HSG in evaluating tubal disease in subfertile populations.
