The tubal factor still remains one the most often reason of female infertility. The applying of colour Doppler sonography and up-to-date constant medium (Echovist-Schering) make possible the comparison of clinical value between colour Doppler imaging and others presently used diagnostic methods. The aim of this study was the comparison of results obtained by means of hysterosalpingography, laparoscopy and hysterosalpingosonography (HSSG) directly observing tubal flow as an estimation of tubal patency.
