Clinical selection of infertile patients for laparoscopy.

For a period of time routine hysterosalpingography and laparoscopy were carried out in every patient complaining of more than 2 years of primary infertility. The records of 433 such patients were retrospectively evaluated according to their clinical aspects. Complete agreement between the two diagnostic methods was found in 70.9% of this unselected population. Almost 50% of the population had some abnormalities in either hysterosalpingography or laparoscopy. According to the patient's past history, pelvic examination, and the duration of infertility, the unselected infertile population was classified into a) high risk infertility and b) low risk infertility. High risk infertility patients had (P less than 0.01) greater abnormal findings at both hysterosalpingography and laparoscopy. In this high risk group we recommend early laparoscopy and the postponement of hysterosalpingographic investigation for patients with suspected cornual occlusion or destruction of ampullary rugae (valuable in assessing tubal damage). Low risk infertility patients had (P less than 0.01) low abnormal findings at both hysterosalpingography and laparoscopy, and in these patients hysterosalpingography does not discriminate the group of higher abnormal laparoscopic findings. Hysterosalpingography can be initially indicated as a less invasive investigation in the low risk group. We conclude that clinical data are very valuable in the selection of infertile patients for early or late laparoscopy.
