The aim of this preliminary study is to analyze and compare tridimensional coded contrast imaging hysterosalpingocontrast- sonography (3D-CCI HyCoSy) with conventional hysterosalpingo-contrast-sonography (HyCoSy) with saline serum for the evaluation of tubal patency in women with sterility.

This was a prospective preliminary observational study performed in the Clinica Universidad de Navarra. Intending to compare 3D-CCI HyCoSy with conventional HyCoSy, we decided and perform conventional HyCoSy between 1st of January 2015 and 15th of February 2015 and 3D-CCI HyCoSy between 16th of February and 15th of April 2015, in different sets of patients. Exclusion criteria were: recent vaginal infection, previous pelvic inflammatory disease, previous salpingectomy or hidrosalpinx diagnosed previously or while performing the ultrasound examination.

Total number of cases was 22 (12 women underwent conventional HyCoSy and 10 a 3D-CCI HyCoSy). The mean age of patients was 33.8 years (SD: 3.2 range: 23–40 years). Three cases (100%) of Fallopian tube obstruction were detected by 3D-CCI HyCoSy and confirmed by laparoscopic tubal chromopertubation (LTC). Four of the six cases (67%) of obstruction detected by conventional HyCoSy were confirmed by hysterosalpingography/LTC (HSG/LTC). Two cases of severe post-procedure pain were reported in women who underwent conventional HyCoSy.

The results of the study show that 3D-CCI HyCoSy was better to visualize the entire Fallopian tube and evaluate its patency
