The comparison of results of hysterosalpingography and chromosalpingolaparoscopy to which 174 patients with sterility problems were subjected confirmed that chromosalpingolaparoscopy is an altogether more accurate and reliable test than hysterosalpingography. However, it also showed that chromosalpingolaparoscopy can give false positives in the study of tubal accessibility. The Authors consider hysterosalpingography a fundamental test when studying sterile women, since it is the only examination enabling the observation of tubal passages and also because it is able to show the above-mentioned possible false positives of chromosalpingolaparoscopy. In agreement with most experts in gynecological endoscopy, the Authors consider hysterosalpingography and chromosalpingolaparoscopy two complementary examinations when studying the uterotubal approach while chromosalpingolaparoscopy is a balance test to be used, with rare exceptions, at the end of the diagnostic iter.
The Authors report the results of a microbiological study of 99 patients who had undergone laparoscopy for infertility and/or pelvic pain. In 64% of the cases the microbiological study gave a positive result and in 45% of these 2 or more microorganisms were isolated; this high positive result was due to the presence of microorganisms with low pathogenicity on the cervical and urethral swabs. The microbiological study, B.S.R. and the leucocytes did not show any significant correlation with the pelvic pathologies found by means of laparoscopy. The only exception to this was Chlamydia T. which gave positive results, both in the direct and indirect test, in 22% of the patients, and which was found most often in the cases where laparoscopy had shown pelvic phlogisis.
While there is no disputing the invaluable role of laparoscopy in the study of the infertile woman, the function of hysterosalpingography (HSG) and hysteroscopy is still left open to debate. Our research concerns 100 infertile women undergoing HSG, hysteroscopy and laparoscopy; the aim of the study was to check the diagnostic accuracy of the three tests. The sensitivity and specificity of HSG vs hysteroscopy were 74.2% and 91.3% respectively. The sensitivity and specificity of HSG vs laparoscopy were 64.5% and 63.3% as regards tubal patency and 6.9% and 92.8% in the diagnosis of tubal phimosis and pelvic pathology. Despite the limits HSG revealed, our results show that a correct study of the infertile woman can only be accomplished by a combination of all three tests; we therefore recommend a combined approach using all three procedures in all infertile patients.

The results of panoramic diagnostic microhysteroscopy are reported in 284 patients with sterility or infertility problems. In 33.5% of the patients, microhysteroscopy revealed uterine pathology; in the majority of cases they were pathologies which are unanimously recognized as being causes of sterility, while in others there were pathologies whose role infertilities is still unclear. There was a good correlation between microhysteroscopy and histology in cases of endometrial hyperplasia and of endometritis, whereas in cases of endometrial polyps and functional diagnosis of the endometrium, the correlation was less satisfactory. Although it is not possible at present to draw definite conclusions about the real value and advantages of microhysteroscopy in the diagnosis of female infertility, we are convinced that it is of great use and that it should be at the basis of any investigation involving the infertile woman.
