This study includes infertile women subjected to combined hysteroscopy and laparoscopy UGA. During hysteroscopy, on each side, three patency test are done successively: flow test, bubble flow test and peristalsis test. Gold standard diagnosis of tubal patency and status is concomitant laparoscopy.
Fallopian tube (FT) function is complex. One of the main functions is transport of sperms for fertilization and transport of the embry for implantation. Hysteroscopic access to Darwish Hysteroscopic Triad allows excellent way to assess FT patency. This study compares three ways of assessing FT patency separably or in combination: flow test, bubble flow test and peristalsis test. Combined bubble flow test and peristalsis test is recently published and coined (Darwishscope)1.
