Background: Tubal dysfunction is responsible for approximately 30% of infertility cases. Tests to
determine if tubes are open and undamaged are an important part of the infertility workup.
Objectives: The aim of this study was to find out the predictive values of bubble test during office
hysteroscopy in assessment of tubal patency. .
Patients and methods: This study included 100 cases underwent for both hysteroscopy and laparoscopy at
the same setting in department of obstetrics and gynecology , Qena University hospital, South Valley
University, Egypt.
Result: In our study 100 women were included , 74 presented by primary infertility and 26 presented by
secondary infertility..In our study using bubble test for tubal patency as primary outcome , the results
showed that bilateral tubal patency represented 71 %, unilateral tubal block represented 11% and bilateral
tubal block 18%.And the results of laparoscopy with MB injection for tubal patency assessment as
secondary outcome , showed that bilateral tubal patency represented 75%, unilateral tubal patency 13 % and
bilateral tubal block 12%.so , we figured out that Evaluation of Diagnostic Performance of bubble test in
hysteroscopy right in sensitivity of 87.9% specificity of 54.5% positive predictive value of 92.1%, negative
predictive value of 42.9% with diagnostic accuracy of 83.1%
Conclusion: Bubble test had a good predictive value in diagnosis of tubal patency through office
hysteroscopy.
