"One-stop shop" for the evaluation of the infertile patient: hystero-salpingo foam sonography combined with two and three dimensional ultrasound and sonohysterography.

Hysterosalpingo-foam sonography (HyFoSy) is considered an acceptable alternative for hysterosalpingography (HSG). By combining HyFoSy with two and three-dimensional (2D and 3D) ultrasound and hysterosonography, a complete fertility work-up can be done. We aimed to evaluate the value of a combined ultrasound examination for fertility work-up. During the study period 113 women were examined. Five of 113 (4.4%) examinations were abandoned due to intra-uterine adhesions that were detected by hysterosonography, and five (4.4%) were abandoned due to technical difficulties. Of 103 women who had completed the examination, 2D ultrasound revealed six patients with hydrosalpinx (5.8%) and sonographic signs of adenomyosis in 13 (12.6%) patients. By combining 2D ultrasound with hysterosonography, two (1.9%) fibroids that were penetrating the uterine cavity and seven (6.8%) endometrial polyps were detected. HyFoSy showed bilateral patent tubes in 58 patients (56.3%), unilateral tubal occlusion in 29 (28.1%) and bilateral tubal occlusion in 16 (15.5%). This study shows that the 'one-stop shop' examination is feasible. The combined examination had detected 16 pathological findings that would have not been detected by HyFoSy alone. Hence, it should be offered to couples undergoing routine infertility work-up.IMPACT STATEMENT The accuracy of the HyFoSy alone has been evaluated in different studies, but this presented ultrasound scan is integrating 4 different modalities in one exam (2D scanning of the pelvis, 3D scanning of the uterus, hysterosonography and HyFoSy) and we were able to evaluate the female pelvic organs, including the uterine cavity, the tubes and the ovaries, in order to expand the range of diagnosed pathologies. The concept of 'one-stop shop' for the evaluation of female pelvis in couples suffering from infertility is feasible, has comparable accuracy as HSG for tubal occlusion, and higher detection rate for uterine malformations. We suggest to incorporate this examination in routine fertility work-up.
