The tests were made at deparment of infertility at the Gynecology and Obstretics Institute of Clinical Center of Serbia in the period from 01.01. untill 31.12.1998. The three hundred patients, on which hysterosalpingography (HSG) was made, and patients, on which chromolaparoscopy was made, were involved by prospectus studies. In the laparoscopy the larger anomalies of the uterus and significant hypoplasy coincide with HSG finding, while hypoplasy in the lower level or uterus arcuatus always can not be established by laparoscopy.The higher frequency of all pathological alterations of the uterus, except the myoma of the uterus, was established by HSG, relating to laparoscopy. Associate pathological alterations were established in the higher percent by HSG than by the laparoscopy, while the single changes were diagnosed in the lower percent.The deficit in the loading of the uterus by the constrast medium, also the changes at the endometrium, could be proved by HSG only. Intravasation can be identified by the both methods. In the diagnosis of the myoma of the uterus, laparoscopy is more important method than HSG.Pathological alterations of the uterus, especially higher anomalies of the uterus and hypoplasy were established in the higher percent by HSG than by the laparoscopy, but statistically the more significant difference was not established in the application of the both methods

Nowadays, hysterosalpingography and laparoscopy are routine methods of exploration of the oviduct passability.The tests were made at department of infertility at the Gynecology and Obstretics Institute of Clinical Center of Serbia in the period from 01.01. untill 31.12.1998. The three hundred patients, on which hysterosalpingography (HSG) was made, and patients, on which chromolaparoscopy was made, were involved by prospectus studies. The analysis shows, that between hysterosalpingographical and laparoscopical investigation of the passability of the oviducts there exists an extremely high statistical difference in the distributions of findings of particular modalities of the passability of the oviduct. Two-way passability of the oviducts with growths of tissue has been established in a higher percentage in the patients who were examined laparoscopically, while the other alternations have been diagnosed hysterographically i a higher percentage. A statistical processing of data resulted in a significantly high statistical difference in the patients with two-way occlusion of the oviducts, whereas for other modalities no statistically significant difference has been established. The most researchers describe high perccentages of growths of tissue, from 64,0% to 72,0%, which have not been established by HSG. Growths of tissue have been confirmed by this investigation in a high percentage (70,0%). Establishing the passability of the oviducts is particularly important for further treatment of the patients.

Falsely negative hysterosalpingographical (HSG) finding presents regular HSG finding, but the laparoscopical is pathological alterations. Falsely positive HSG findings presents pathological HSG finding, but the laparoscopical is regular finding. A high frequency of falsely negative results can be explained first of all by the presence of growths of tissue. It is known that by HSG peritubar adhesions can be suspected, but they can be diagnosed with absolute certainty only laparotomically and laparoscopically. In the period from 01.01. untill 31.12.1998. the falsely negative and falsely positive HSG findings were identified on 60 patients, which were tested by HSG method and laparoscopy. Obtained results are showed ta2 bular and graphically. Statistical data processing is carried out by Mc Nemar test (c MCN test). In the case of the HSG pathological finding, the same pathological finding has been proved in 28 (63,6%) persons, a different pathological finding in 9 (20,5%) and regular finding in 7 (15,9%). The frequency of falsely negative HSG findins is 25,0% and falsely positive HSG findings 15,9%. The frequency of falsely positive findings extends from 14,6%, 17%, 20% to 29,6%. The majority of authors state that the incidence of falsely negative findings ranges from 15,5%, 15,9%, 18%, 20,7%, 22% to 24,0%. The pathological HSG points out to the necessity of laparoscopy, while the regular HSG is not sufficient proof of normal oviducts and the peritoneal factor
