“…Although diminished in participant numbers, these studies bring forth a consistency that supports HyCoSy as a reliable and reproducible screening procedure for subfertility (16,37,41,43,45,(49)(50)(53)(54)(55)(56)(57)(58).…”

“…Hysterosalpingo contrast sonography (HyCoSy) has become an important tool for the diagnosis of uterine or tubal pathologies [12]. According to the literature, this technique has a higher sensitivity than HSG (0.80 versus 0.53) [13], and the specificity (0.84 versus 0.87) is similar for both exams [14]. …”

Hysterosalpingography in the workup of female infertility: indications, technique and diagnostic findings

ObjectivesTo evaluate the spectrum of diagnostic findings in hysterosalpingography (HSG) examinations performed at our institution between 2006–2010 and their prognostic significance for treatment decisions and fertility outcomes.MethodsPatients were filtered from our PACS. Pathological HSG studies were re-evaluated. Indications for referral, technical success and diagnostic findings were analysed. Pathological findings were correlated with further diagnostic workups, treatments and fertility outcomes.ResultsOf 411 HSG examinations, 226 (55 %) were normal, 94 (23 %) showed minor abnormalities and 5 (1.2 %) were not diagnostic. Eighty-six (21 %) examinations were pathological. Twenty-nine patients underwent subsequent laparoscopy, during which proximal tubal occlusion diagnosed at HSG was ruled out in 9/23 cases. Follow-up information was unavailable for 20 patients. Nineteen of 66 patients with follow-ups after pathological HSG had at least one subsequent successful pregnancy. Forty-one patients had no further treatment and no pregnancies.ConclusionsThe detection rate for pathologies at HSG was low (21 %). There was a high false-positive rate (39 %) for proximal tubal occlusion, most likely because of spasms, demonstrating the importance of delayed imaging after injection of antiperistaltic agents. HSG remains a valuable diagnostic tool. Our results, however, indicate that this technique should be more selectively indicated.Main Messages• Good acceptance of HSG by the patients. No complications with antibiotic prophylaxis.• Low detection rate (21 % pathological exams) for pathologies in our study.• High false-positive rate for proximal tubal occlusion.• This demonstrates the importance of waiting longer after injection of buscopan.• High pregnancy rate in pathological cases: Indication too broad or even a therapeutic effect of HSG?

“…[31] In a diagnostic accuracy study of HyCoSy performed with air and saline (Hydro-HyCoSy) and with contrast media (SonoVue-hyCoSy) considering HSG and/or chromopertubation as reference tests, SonoVue-HyCoSy has been found to be more accurate than Hydro-HyCoSy for the assessment of fallopian tubes. [32] While the Sensitivity, specificity and PPVs and NPVs of Hydro-HyCoSy were 91%, 71%, 55% and 95%, respectively, they were 87%, 84%, 69% and 94% respectively for SonoVue-HyCoSy. The diagnostic accuracy of Hydro-HyCoSy and of SonoVue-HyCoSy were 77% and 85%, with a Cohen's kappa of 0.52 and 0.66, respectively.…”

Fallopian tubes make a vital portal for transfer of gametes and embryo. Tubal factor is responsible for infertility in 25-35% of cases. Hysterosalpingography (HSG) has been used to evaluate the uterine cavity and the tubal status since decades. It uses iodinated contrast and X-rays and is painful and inconvenient for patient. Laparoscopy is considered to be the gold standard for tubal evaluation, but is an operative procedure and needs anesthesia. Though ultrasound is a modality of choice for assessment of uterus and ovaries, it does not allow assessment of the fallopian tube unless there is any fluid surrounding it or inside the lumen. This fluid interface can be created artificially by introducing saline in the uterine cavity and fallopian tubes and scanning simultaneously. The procedure is named Saline infusion HSG. Saline infusion sonohysterosalpingography (SIS) can be done with B mode US and Doppler. SIS can demonstrate a patent tube but if blocked, the site of block cannot be demonstrated. Ultrasound contrast agents can be used for tubal assessment using contrast mode on the scanners. This procedure is known as hystero-contrast sonography (HyCoSy). This actually shows the passage of hyperechoic contrast agent through tubal lumen and delineates it and locates the site of block. Using the volume ultrasound may even make the demonstration of tubal status and fimbriae better. Results of HyCoSy have been found to correlate well with laparoscopic findings, which are a gold standard. It is recommended by National Institute for Health and Clinical Excellence as a primary investigation for tubal assessment in patients without any positive history of tubal damage and also can replace a second look laparoscopy.

Transvaginal Hysterosalpingo‐Contrast Sonography (HyCoSy) Compared with Chromolaparoscopy

Abstract: HyCoSy showed good diagnostic performance in the evaluation of the fallopian tubes and uterus in infertile women. The adverse events reported in this study are minor and procedure-related (catheter insertion) rather than the trial substance.
