Abstract
ObjectiveOur purpose was to investigate the predictive value of visible air bubble sign for real tubal patency during hysteroscopic procedures. MethodsIn this cross-sectional study, clinical data of 61 infertile women who underwent diagnostic hysteroscopy and laparoscopy have been analysed. ResultsMean age of patients was 33.45 ± 3.25 years. Bubble sign for the detection of patency demonstrated 73 % (95 % CI: 57–86 %) sensitivity, 70 % (95 % CI: 46–88 %) specificity, a positive predictive value of 83 % (95 % CI: 67–94 %), and a negative predictive value of 56 % (95 % CI: 35–76 %). ConclusionsA visible tubal “flow” of air bubbles during hysteroscopy was not accurate in the prediction of tubal patency.
