Objective: To determine whether hysterosalpingo-foam sonography (HyFoSy) is a less painful first line tubal patency test than serial hysterosalpingography (HSG).

Design: A two-center, prospective, open-label, randomized, controlled trial.

Setting: University hospital and teaching hospital.

Patient(s): 40 subfertile women, ages 18 to 41 years, with an indication for tubal patency testing as part of the fertility workup according to the Dutch Nederlandse Vereniging voor Obsteterie & Gynaecologie-guidelines.

Intervention(s): Tubal patency testing by HyFoSy versus serial HSG.

Main Outcome Measure(s): Visual Analogue Scale (VAS) pain scores during tubal patency testing.

Result(s): The median VAS score for pain perception during the HyFoSy procedure was 1.7 cm (interquartile range: 2.1) compared with 3.7 cm (interquartile range: 4.2) during HSG. The HyFoSy procedure also had a statistically significantly shorter procedure time compared with HSG, with a median of 5.0 minutes (interquartile range: 3.0) for HyFoSy versus 12.5 minutes (interquartile range: 16.0) for HSG.

Conclusion(s): The HyFoSy procedure is a less painful and less time-consuming tubal patency test compared with HSG.

Clinical Trial Registration Number: Netherlands National Trial Register NTR3457.

: Hysterosalpingography (HSG) is pivotal in delineating tubal pathology, but is associated with pain and exposure to ionizing radiation. This study investigated which reproductive factors predict HSG-identified tubal pathology. : From May 2016 to August 2023, 3322 infertile females with HSG (mean age 33.

Background: Chronic endometritis (CE), frequently asymptomatic, is associated with female infertility. Fallopian tube obstruction (FTO) is also one of the factors contributing to female infertility. More than 90% of cases of proximal FTO can be successfully treated after fallopian tubal recanalization (FTR) and the spontaneous pregnancy rate of treated women after FTR is only about 30%.

Article Synopsis
  • The study investigates the occurrence of contrast-induced nephropathy (CIN) in 65 women who underwent hysterosalpingography (HSG) for infertility evaluations.
  • The results showed a CIN rate of 12.3% among participants, with a significant difference in baseline serum creatinine levels between women with and without CIN.
  • Baseline serum creatinine levels were identified as an independent risk factor for developing CIN following the HSG procedure.

Objective: To determine the frequency of uterine contrast agent intravasation during HyCoSy/HyFoSy for assessing tubal patency in infertile women.

Methods: Prospective observational multicenter study performed in nine European university hospitals, comprising a series of non-consecutive women who underwent HyFoSy (ExEm foam) for tubal patency assessment in the context of infertility between May 2016 and December 2022. All examinations were performed using the same scanning protocol.
