Routine hysteroscopy in infertility?

Fifty patients from the infertility Clinic at Groote Schuur Hospital who underwent laparoscopy as part of their work-up had a routine hysteroscopy at the same time, with the Hamou II hysteroscope. In all cases carbon dioxide was used as the distending medium. Only 4 patients had abnormalities detected by hysteroscopy. Three out of those 4 abnormalities could have been diagnosed by hysterosalpingography. Compared with hysteroscopy the diagnostic value of hysterosalpingography as a routine screening procedure was found to be adequate.
