OBJECTIVE Infertility problem affects more than 70 million couples worldwide, 5-15% of which are couples in their reproductive age. Less and less invasive endoscopic methods like transvaginal hydrolaparoscopy have been developed by technological progress. This method enables not only precise identification, but is now increasingly used for treatment of tubal and peritoneal factor pathology, which cause approximately 35 per cent of female infertility. OBJECTIVE Evaluation of transvaginal hydrolaparoscopy (HLTV) usefulness for diagnosis of tubal infertility comparing to standard laparoscopy and hysterosalpingography (HSG). RESULTS In evaluation of patent fallopian tubes results of HLTV and HSG examinations are coincide in 87%, while obstruction diagnosed in HSG is confirmed only in 37% during HLTV examination. Transvaginal hydrolaparoscopy and HSG have similar sensitivity and specificity in diagnosis of hydrosalpinx, which is up to 100% . In comparison with HLTV histerosalpingography is less effective in evaluation of peritubal dilatations and adhesions. Both laparoscopic surgery and transvaginal laparoscopy have the same high sensitivity in diagnostics of the fallopian tubes patency and hydrosalpinx, which is up to 100%. In evaluation of peritubal adhesions and dilatations the results are very similar. CONCLUSIONS 1. HLTV is a highly useful method in evaluation of the fallopian tubes pathologies which is significantly more sensitive than HSG in evaluation of such lesions as peritubal adhesions and obstructed fallopian tubes. 2. HLTV is as effective as laparoscopy in evaluation of patency and lesions of the fallopian tubes. 3. HLTV is a less invasive method, much better tolerated than laparoscopy and more suitable for the group of overweight patients. 4. Final assessment of HTLV technique will be possible following performance of a greater number of studies, where the foregoing conclusions present only initial observations.
