A specially designed rigid salpingoscope has been developed to allow inspection of the tubal mucosa during laparoscopy. The presence and extent of intratubal adhesion formation can be evaluated more accurately by this technique than by either HSG or laparoscopy. In 22 patients with bilateral hydrosalpinges, an intrauterine pregnancy rate of 59% was achieved in the group of patients with very mild mucosal lesions and absence of mucosal adhesions.
