[Determination of the functional state of the uterine tube by hysteroscopy].

The authors present their observations on the uterine os and signs of patency of the Fallopian tubes based on 240 cases of infertility examined by hysteroscopy. The shape of the cornual region, the adjacent pathological structures, ie., adhesions, polyps, fibroids etc., the outflow of the distending medium towards the Fallopian tubes and the movement of the tubal os were visualised. Intrauterine pressure and flow data were recorded in order to judge tubal patency. The funnel-shaped (in contrast with the flat type) cornual region, rhythmic contraction of the tubal os, the outflow of distending medium, intrauterine pressure under 100-120 Hgmm and standard 25-50 ml/min medium flow were evaluated as characteristic diagnostic signs of tubal patency.
