Description

The primary aim of this study is to evaluate the relalibilty of (1.) the hysteroscopic visualization of a “tubal flow” and (2.) the “Parryscope technique” as compared to the gold standard, namely laparoscopic chromopertubation. The data show that yysteroscopic prediction of Fallopian tube patency was possible in a statistically significant manner in both study groups (p< 0.05). The Parryscope® technique achieved higher sensitivity (90.6%, 95% CI: 61.7-98.4) and specificity (100%, 95% CI: 90.0-100.0) than the flow technique (sensitivity: 73.7%, 95% CI: 48.8-90.9 and specificity: 70.7%, 95% CI: 54.5-83.9).

In a prospective, monocentral, randomized study, 60 women ages 18-45 were enrolled between May and October, 2019 for combined hysteroscopy and laparoscopy with chromopertubation, as part of their infertility evaluation at the Clinical Division of Gynecologic Endocrinology and Reproductive Medicine of the Medical University of Vienna, Austria. All women affirmed informed consent in writing. Patients who had already undergone removal of one or both Fallopian tubes were not eligible for participation. Immediately before commencing surgery, the senior surgeon opened the patient’s study envelope determining which hysteroscopic tube assessment technique was to be performed (with block randomization). The study was approved by the Institutional Review Board of the Medical University of Vienna (IRB number 1341/2019) and was registered in ClinicalTrials.gov (ID NCT04077242).
