Abstract
The fallopian tubes are essential for human fertility, facilitating the movement of sperm and oocytes to the fertilization site and transporting fertilized oocytes to the uterus. Infertility can result from changes in the fallopian tubes due to tubal endometriosis and women's aging. In this study, we modeled human fallopian tubes with and without endometriosis for different women's age groups to evaluate the chances of normal sperm cells reaching the fertilization site and oocytes arriving at the uterine cavity. For this purpose, we employed a distinctive combination of simulation tools to develop a dynamic three-dimensional (3D) model of normal human sperm cells and oocytes swimming inside normal and endometriosis-affected human fallopian tubes for different women's group ages. We observed that in tubal endometriosis cases, fewer sperm cells reach the fertilization site and more oocytes become trapped in the tube walls compared to normal tubes. Additionally, aging decreases the number of sperm cells and oocytes reaching the fertilization site in normal and endometriosis-affected tubes. Our model evaluates the mechanisms of sperm and oocyte behaviors due to women's aging and fallopian tube issues caused by endometriosis, presenting new avenues for developing diagnostic and treatment tools for tubal endometriosis and age-related infertility issues.

Abstract
STUDY QUESTION What are the costs and effects of tubal patency testing by hysterosalpingo-foam sonography (HyFoSy) compared to hysterosalpingography (HSG) in infertile women during the fertility work-up? SUMMARY ANSWER During the fertility work-up, clinical management based on the test results of HyFoSy leads to slightly lower, though not statistically significant, live birth rates, at lower costs, compared to management based on HSG results. WHAT IS KNOWN ALREADY Traditionally, tubal patency testing during the fertility work-up is performed by HSG. The FOAM trial, formally a non-inferiority study, showed that management decisions based on the results of HyFoSy resulted in a comparable live birth rate at 12 months compared to HSG (46% versus 47%; difference -1.2%, 95% CI: -3.4% to 1.5%; P = 0.27). Compared to HSG, HyFoSy is associated with significantly less pain, it lacks ionizing radiation and exposure to iodinated contrast medium. Moreover, HyFoSy can be performed by a gynaecologist during a one-stop fertility work-up. To our knowledge, the costs of both strategies have never been compared. STUDY DESIGN, SIZE, DURATION We performed an economic evaluation alongside the FOAM trial, a randomized multicenter study conducted in the Netherlands. Participating infertile women underwent, both HyFoSy and HSG, in a randomized order. The results of both tests were compared and women with discordant test results were randomly allocated to management based on the results of one of the tests. The follow-up period was twelve months. PARTICIPANTS/MATERIALS, SETTING, METHODS We studied 1160 infertile women (18-41 years) scheduled for tubal patency testing. The primary outcome was ongoing pregnancy leading to live birth. The economic evaluation compared costs and effects of management based on either test within 12 months. We calculated incremental cost-effectiveness ratios (ICERs): the difference in total costs and chance of live birth. Data were analyzed using the intention to treat principle. MAIN RESULTS AND THE ROLE OF CHANCE Between May 2015 and January 2019, 1026 of the 1160 women underwent both tubal tests and had data available: 747 women with concordant results (48% live births), 136 with inconclusive results (40% live births), and 143 with discordant results (41% had a live birth after management based on HyFoSy results versus 49% with live birth after management based on HSG results). When comparing the two strategies-management based on HyfoSy results versus HSG results-the estimated chance of live birth was 46% after HyFoSy versus 47% after HSG (difference -1.2%; 95% CI: -3.4% to 1.5%). For the procedures itself, HyFoSy cost €136 and HSG €280. When costs of additional fertility treatments were incorporated, the mean total costs per couple were €3307 for the HyFoSy strategy and €3427 for the HSG strategy (mean difference €-119; 95% CI: €-125 to €-114). So, while HyFoSy led to lower costs per couple, live birth rates were also slightly lower. The ICER was €10 042, meaning that by using HyFoSy instead of HSG we would save €10 042 per each additional live birth lost. LIMITATIONS, REASONS FOR CAUTION When interpreting the results of this study, it needs to be considered that there was a considerable uncertainty around the ICER, and that the direct fertility enhancing effect of both tubal patency tests was not incorporated as women underwent both tubal patency tests in this study. WIDER IMPLICATION OF THE FINDINGS Compared to clinical management based on HSG results, management guided by HyFoSy leads to slightly lower live birth rates (though not statistically significant) at lower costs, less pain, without ionizing radiation and iodinated contrast exposure. Further research on the comparison of the direct fertility-enhancing effect of both tubal patency tests is needed.

Abstract
Objective To determine the feasibility, safety, and outcomes of an oil-based, iodinated contrast using office-based, ultrasound-imaged hysterosalpingography in women with infertility. Design Randomized Controlled Double Blind Clinical Trial. Setting Academic health center. Interventions Tubal flushing with oil-based contrast medium (Lipiodol UF) versus saline. Main Outcome Measures Ongoing pregnancy rate, pain, quality of life, and thyroid function. Results Forty-eight patients (24 in each group) were analyzed. The groups were well-matched at baseline. Ongoing pregnancy was noted in 17% (4/24) of the oil-contrast group versus 37% (9/24) in the saline group. Saline group patients more frequently initiated infertility therapy in the six-month follow-up period (saline, 67% vs. oil, 33%), and no serious adverse events in either group. There were no differences in pain from the procedure between groups. There were no differences in thyroid function tests postprocedure between groups, but within the oil-contrast group, there was a slight increase in thyroid-stimulating hormone (post vs. preratio of geometric means: 1.18; 95% confidence interval [CI], 1.02-1.38) and decrease in Free T4 (postdifference vs. predifference in means: 0.08 ng/dL; 95% CI, -0.14 to -0.01). Immediately after the test, the physicians correctly guessed 79% of oil and 71% of saline randomization assignments, whereas patients correctly guessed 63% of oil and 38% of saline. Conclusions This pilot study demonstrates the safety and feasibility of giving an oil-based contrast medium during ultrasound-imaged hysterosalpingography. Pregnancies were seen after oil-based administration, and this contrast is associated with minor thyroid function impairment.

Abstract
Infertility is a problem that affects both developed and developing countries today. Many couples choose to have financial stability before conception, irrespective of age. Tubal blockage accounts for 30%-40% of a woman's fertility. Congenital abnormalities, acute and persistent inflammatory diseases, endometriosis, and different pathologies are associated with infertility and cause partial or complete obstruction of the fallopian tubes. Approximately 30% of women experience infertility due to fallopian tube illness, with 10%-25% of these women experiencing proximal fallopian tube obstruction. The fallopian tube is an integral part of the union of sperm, and its normal function is a prerequisite for natural conception. Tubal obstruction is a common cause of infertility. These patients are keen to unblock their blocked fallopian tubes and restore reproductive function. Accurate diagnosis and optimal treatment options are essential for treating infertility.

Abstract
BACKGROUND In 60% of sterile couples a female factor is present, with these being tubal factors in 30-50% of cases. A tubal patency test is also required in women without a male partner undergoing fertility treatment. Thus, an accurate, safe and tolerable technique should be available. The aim of this study is to determine and to compare hysterosalpingo-foam sonography (HyFoSy) and hysterosalpingography (HSG) tolerability in terms of pain and anxiety. METHODS This is a prospective real-world setting multicentre study conducted in two tertiary hospitals in Madrid. 210 infertile women/women without a male partner looking to get pregnant were recruited; 111 for the HyFoSy group and 99 for the HSG group. Tolerability was measured in terms of anxiety by the State Trait Anxiety Inventory (STAI) and pain by the Visual Analogue Scale (VAS). RESULTS Median VAS score in HyFoSy group was 2 (P25; P75: 1; 3) versus 5 (4; 8) in HSG group, p < 0.001. The median State-STAI score in the HSG group was 18 points (10; 26) versus 10 (7; 16) in the HyFoSy group (p < 0.001); the median Trait-STAI score in the HSG group was 15 (11; 21) versus 13 (9; 17) in the HyFoSy group (p = 0.044). CONCLUSIONS HyFoSy shows higher tolerability to both: pain and anxiety. It is related to less pain and less post-test anxiety than HSG.

Abstract
Imaging plays a crucial role in evaluating newborns and infants with cloacal and urogenital malformations. Contrast-enhanced genitosonography (ceGS) and contrast-enhanced colosonography (ceCS) are sensitive and radiation-free alternatives to fluoroscopic genitography and colography for diagnosis and surgical planning. These imaging techniques are performed by instilling a US contrast agent into specific body cavities to define the genitourinary and colorectal anatomy. This review article presents the experience with ceGS and ceCS applications in children, focusing on the background, examination technique, and interpretation of imaging findings, as well as strengths and weaknesses compared to conventional techniques.

Abstract
OBJECTIVE To explore the association between Fallopian tubal patency and the slope of the increasing pressure curve for ultrasound contrast agent. MATERIALS AND METHODS A total of 136 patients underwent transvaginal 4-dimensional hysterosalpingo-contrast sonography (TVS 4D HyCoSy) between August 2015 and January 2016. We divided the patients into 3 groups according to different Fallopian tubal patency status: 71 patients (48.97%) in bilateral tubal patency group, 45 (31.03%) in unilateral tubal patency group, and 20 in bilateral tubal nonpatent group. The ultrasound contrast agent was injected and the pressure curve was recorded automatically in real time using a liquid-injecting machine that traces it as a pressure curve. The slopes of the different groups are compared through independent sample t test. RESULTS The slopes of the 3 groups were 1.242 ± 0.572, 1.472 ± 0.638, and 2.068 ± 1.236 kPa/s. A correlation was observed between the slope of the increasing pressure curve and tubal patency (R = 0.287, P < .05). The slopes differed significantly between the bilateral tubal patency group and bilateral tubal nonpatent group (P = .001) and between the unilateral tubal patency group and bilateral tubal nonpatent group (P = .012). However, the difference between the bilateral tubal patency and unilateral tubal patency groups was not significant (P = .266). CONCLUSION The increase of the injecting pressure curve's slope for contrast agent during 4D HyCoSy is associated with the nonpatent degree of the tube. This condition can be used as an objective index of tubal patency and can be a reference in diagnosis and treatment.

Thus, the objective of this study is to compare the diagnostic accuracy of the hysterosalpingo-foam sonography (HyFoSy) in tubal patency testing with the traditional hysterosalpngography (HSG) for establishing a new diagnostic strategy in infertility. Material and Methods: Prospective observational diagnostic accuracy was performed in a private fertility clinic in which 106 women undergoing a preconceptionally visit were recruited. All of them had low risk for tubal disease, had performed an HSG and were negative for Chlamydia trachomatis antibody. Main outcome measures were tubal patency and pain grade. Results: Evaluation of tubal patency by HyFoSy showed a total concordance with the results of the previous HSG in 72.6% (n = 77), and a total discordance for 4.7% (n = 6), with the inter-test agreement Kappa equal to 0.57, which means moderate concordance. Among the patients, 59.1% did not report pain during the procedure, while the remaining 48.1% indicated pain in different degrees; patients usually report less pain and only 6.6% described more pain with HyFoSy than with HSG (OR 6.57 (CI 95% 3.11–13.89)). Clinical outcomes after performing HyFoSy were not affected. Conclusions: HyFoSy is in concordance with HSG regarding tubal patency results and it is a less painful technique than HSG. HyFoSy is more economical and can be performed in an exam room only equipped with an ultrasound scanner. Based on these results, HyFoSy could be the first-choice diagnostic option to assess tubal patency in patients with low risk of tubal disease.

Pain Perception and Side Effects During Saline Infusion Sonohysterography With a Balloon Catheter: A Randomized Comparative Study of Cervical Versus Intrauterine Catheter Placement. JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2020; 39:1829-1837. [PMID: 32302018 DOI: 10.1002/jum.15292] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/08/2019] [Revised: 03/20/2020] [Accepted: 03/23/2020] [Indexed: 06/11/2023]
Abstract
OBJECTIVES This study aimed to evaluate whether the site of the balloon placement into either the uterine cavity or cervical canal can affect the intensity of pain during sonohysterography. METHODS In this randomized clinical trial, women who underwent saline infusion sonohysterography (SIS) were randomized to intracervical or intrauterine balloon placement between May 2012 and May 2014. The examination was scheduled at the early follicular phase of the menstrual cycle. The primary outcome measures included the degree of pain after inflation and then after deflation of the balloon catheter. Data were analyzed on the basis of the intention-to-treat principle for each woman who underwent SIS. RESULTS A total of 300 infertile women were assigned to the treatment groups. There were no significant differences in inflation and deflation pain and the total procedure time between the 2 groups. The total volume of required saline for adequate distention of the cavity was significantly lower in the cervical group than the intrauterine group (p = .015). Nulliparous women had insignificantly more pain after the initial inflation of the balloon compared with multiparous women (p = .069). The pain score was not associated with patients' age, the volume of the saline infused, the presence of intrauterine abnormality, and the procedure time. CONCLUSIONS Intracervical catheter placement did not reduce pain during or after SIS. However, intracervical balloon insertion requires a less-significant volume of saline compared with intrauterine placement, leading to a reduced risk of intrauterine infection and the spread of malignant endometrial cells into the peritoneal cavity at the time of the procedure.

Abstract
PURPOSE To estimate the diagnostic efficacy of saline-air hysterosalpingo-contrast sonography (SA-HyCoSy) compared with the modified hysterosalpingogram (mHSG) for confirmation of both coil location and tubal occlusion following hysteroscopic sterilization. METHODS This study included 19 women who underwent both SA-HyCoSy and mHSG where 1 test was followed by the other. Sensitivity, specificity, and positive and negative predictive values for tubal occlusion against the mHSG were calculated for each fallopian tube by 2 independent interpreters. Interrater reliability was assessed using Cohen κ statistic. Procedure time and pain level by 11-point numeric rating scale of SA-HyCoSy and mHSG were also compared. RESULTS Thirty-eight fallopian tubes were evaluated. Tubal occlusion was noted in 97.3% of tubes for both interpreters with the mHSG compared with 92.1% and 94.7% with SA-HyCoSy. The positive and negative predictive values for tubal occlusion were 100%/100% and 50%/33%, respectively, with an overall agreement of 97.4% and 95.7%, κ = 0.48, P < 0.01. Saline-air HyCoSy changed interpretation of coil insert location in 50% and 44.7% for each interpreter, being downgraded from optimal to satisfactory in 42.9% (9/21) and 36% (9/25) and upgraded to optimal in 58.8% (10/17) and 61.5% (8/13), respectively. There were no statistically significant differences in procedural time (7.5 vs 9.4 minutes, P > 0.05) or maximum pain scores (2.3 vs 3.1, P > 0.05) for the mHSG compared with SA-HyCoSy. CONCLUSIONS Our findings revealed a high degree of diagnostic accuracy with SA-HyCoSy for tubal occlusion, although coil location changed in nearly half of cases. Avoidance of radiation and patient convenience/compliance with SA-HyCoSy may outweigh the drawbacks.

Abstract
In this meta-analysis, we aimed to compare the diagnostic accuracy of 2D- and 3D/4D-HyCoSy for the assessment of tubal occlusion in women with infertility, using a laparoscopic tubal chromoperturbation dye test as the reference standard. Studies assessing 2D- and 3D/4D-HyCoSy for the assessment of tubal occlusion in women with infertility were searched from January 1990 to April 2019 using Medline and Web of Science databases by three of the authors, using the terms: 'hysterosalpingo-contrast-sonography', 'sonohysterosalpingography', 'HyCoSy', 'HyFoSy', 'three-dimensional', 'four-dimensional', 'ultrasound', 'tubal patency' and 'tubal occlusion'. Data quality was determined using the QUADAS-2 tool. Thirty articles were included; twenty-one studies used 2D-HyCoSy to assess tubal occlusion, six used 3D/4D-HyCoSy, one study used both techniques but in a different set of patients and two used both techniques in the same patients. The risk of bias for most studies was low as determined by QUADAS-2, except for the patient selection domain. Overall, pooled estimated sensitivity and specificity of 2D-HyCoSy were 86% (95% CI = 80%-91%) and 94% (95% CI = 90%-96%), respectively. The corresponding figures for 3D/4D HyCoSy were 95% (95% CI = 89%-98%) and 89% (95% CI = 82%-94%). High heterogeneity was found for both sensitivity and specificity. No statistically significant differences were found between the methods (p = 0.13). We concluded that 2D-HyCoSy has a similar diagnostic performance to 3D/4D-HyCoSy.

Abstract
PURPOSE To compare hysterosalpingo-contrast-sonography (HyCoSy) and magnetic resonance-hysterosalpingography (MR-HSG) in the diagnosis of fallopian tubal patency. MATERIALS AND METHODS The databases of PubMed, Embase, and the Cochrane Library were searched for records up to November 30, 2019. Studies involved in the diagnostic detection of HyCoSy or MR-HSG for fallopian tubal patency using conventional HSG or laparoscopy as the reference test were included. Data was analyzed by meta-analysis. We compared sensitivity, specificity, positive and negative likelihood ratios (PLR and NLR), diagnostic odds ratio (DOR), and summary receiver operating characteristic (sROC) plots of both HyCoSy and MR-HSG. Quality was assessed using the QUADAS-2 tool. RESULTS The analysis included 24 articles involving 1340 patients. HyCoSy was studied in 17 studies, and MR-HSG was studied in seven studies. For HyCoSy in diagnosis of fallopian tubal patency, pooled sensitivity was 89 % (95 % confidence interval [CI], 87 %-91 %), and specificity was 93 % (95 % CI, 91 %-94 %). For MR-HSG in diagnosis of fallopian tubal patency, pooled sensitivity was 100 % (95 % CI, 98 %-100 %), and specificity was 82 % (95 % CI, 74 %-89 %). The sROC showed similar diagnostic accuracy for MR-HSG and HyCoSy. 3D/4D HyCoSy with ultrasound microbubbles had equal sensitivity (95 % vs. 100 %, P = 0.186) and significantly higher specificity (94 % vs. 82 %, P = 0.005) compared with MR-HSG. CONCLUSIONS HyCoSy and MR-HSG showed similar overall diagnostic performance for diagnosing fallopian tubal patency. 3D/4D HyCoSy with ultrasound microbubbles could significantly improve the diagnostic specificity of HyCoSy.

Abstract
PURPOSE To compare saline infusion sonohysterography (SIS) versus hysterosalpingogram (HSG) for confirmation of tubal patency. METHODS Secondary analysis of a randomized controlled trial, Pregnancy in Polycystic Ovary Syndrome II (PPCOS II). Seven hundred fifty infertile women (18-40 years old) with polycystic ovary syndrome (PCOS) were randomized to up to 5 cycles of letrozole or clomiphene citrate. Prior to enrollment, tubal patency was determined by HSG, the presence of free fluid in the pelvis on SIS, laparoscopy, or recent intrauterine pregnancy. Logistic regression was conducted in patients who ovulated with clinical pregnancy as the outcome and HSG or SIS as the key independent variable. RESULTS Among women who ovulated, 414 (66.9%) had tubal patency confirmed by SIS and 187 (30.2%) had at least one tube patent on HSG. Multivariable analysis indicated that choice of HSG versus SIS did not have a significant relationship on likelihood of clinical pregnancy, after adjustment for treatment arm, BMI, duration of infertility, smoking, and education (OR 1.14, 95% CI 0.77, 1.67, P = 0.52). Ectopic pregnancy occurred more often in women who had tubal patency confirmed by HSG compared to SIS (2.8% versus 0.6%, P = 0.02). CONCLUSIONS In this large cohort of women with PCOS, there was no significant difference in clinical pregnancy rate between women who had tubal patency confirmed by HSG versus SIS. SIS is an acceptable imaging modality for assessment of tubal patency in this population.

Abstract
OBJECTIVES The purpose of the study was to assess the accuracy of hysterosalpingo-contrast sonography (HyCoSy) for evaluation of the uterine cavity. METHODS Hysterosalpingo-contrast sonography was compared with hysteroscopy for assessment of the uterine cavity. This work was a descriptive prospective study to assess the concordance between pathologic intrauterine findings using the Cohen κ coefficient. Ninety infertile patients from Puerta de Hierro University Hospital were included in the study. They underwent HyCoSy between June 2016 and April 2017. Fifteen of them had pathologic findings in the uterine cavity during HyCoSy and therefore underwent hysteroscopy. Clinical and sonographic findings were compared in those 15 patients by to evaluate the agreement between both techniques. RESULTS In this study, intrauterine sonographic findings on HyCoSy and hysteroscopic features of the uterine cavity reached 100% concordance, with a κ coefficient of 1.000 and a 100% agreement rate. CONCLUSIONS Hysterosalpingo-contrast sonography permits a very accurate evaluation of the uterine cavity, which could be of interest for infertile patients who might be examined for tubal patency.

Abstract
Abstract Contrast-enhanced ultrasound (CEUS) is a technique that has developed as an adjunct to conventional ultrasound. CEUS offers a number of benefits over conventional axial imaging with computerised tomography and magnetic resonance imaging, primarily as a “beside” test, without ionising radiation or the safety concerns associated with iodinated/gadolinium-based contrast agents. Intravascular use of ultrasound contrast agents (UCAs) is widespread with extensive evidence for effective use. Despite this, the potential utility of UCAs in physiological and non-physiological cavities has not been fully explored. The possibilities for endocavitary uses of CEUS are described in this review based on a single-centre experience including CEUS technique and utility in confirming drain placement, as well as within the biliary system, urinary system, gastrointestinal tract and intravascular catheters. Teaching Points • CEUS offers an excellent safety profile, spatial resolution and is radiation free. • Endocavitary CEUS provides real-time imaging similar to fluoroscopy in a portable setting. • Endocavitary CEUS can define internal architecture of physiological cavities. • Endocavitary CEUS can confirm drain position in physiological and non-physiological cavities.

One-step transvaginal three-dimensional hysterosalpingo-foam sonography (3D-HyFoSy) confirmation test for Essure® follow-up: a multicenter study. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2018; 51:134-141. [PMID: 28067009 DOI: 10.1002/uog.17398] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/09/2016] [Revised: 10/31/2016] [Accepted: 12/13/2016] [Indexed: 06/06/2023]
Abstract
OBJECTIVE To evaluate, in patients who underwent Fallopian-tube sterilization by hysteroscopic insertion of an Essure® device, the feasibility and accuracy of three-dimensional (3D) transvaginal sonography (TVS) to check the position of the device and 3D hysterosalpingo-foam sonography (3D-HyFoSy) using contrast-enhanced gel foam to assess consequent tubal occlusion. METHODS This was a prospective multicenter study conducted from June 2012 to July 2014 in four Italian centers, which included 50 women who underwent hysteroscopic Essure microinsert placement in a total of 95 Fallopian tubes. Placement of the microinserts was performed in an outpatient setting following standard procedure recommendations. All patients underwent transvaginal 3D-HyFoSy and hysterosalpingography (HSG) approximately 12-14 weeks after the procedure. The position of the devices was first checked on 3D-TVS and classified according to specific criteria (Positions A, B, C and D). Then, 3D-HyFoSy with ExEm® gel foam as the ultrasound contrast agent was performed to confirm tubal occlusion by the absence of contrast agent within the tubes and/or around the ovaries. To evaluate the feasibility of 3D-HyFoSy, consecutive volume acquisitions were performed while injecting the gel foam. After sonographic evaluation, women underwent HSG to assess the success of sterilization, as standard methodology. Side effects and pain evoked during and after 3D-HyFoSy and HSG were evaluated using a numeric pain rating scale. RESULTS On 3D-TVS, 10 devices (10.5%) were in Position A, two (2.1%) in Position B, 59 (62.1%) in Position C and 24 (25.3%) in Position D. During 3D-HyFoSy, tubal occlusion was observed in 89 of 95 tubes (93.7%). In the six cases in which the passage of the contrast was observed, one device (16.7%) was in Position B, one device (16.7%) in Position D and four devices (66.7%) were found to lie in Position C. Tubal patency was confirmed at HSG with a concordance rate of 100%. The mean pain score associated with 3D-HyFoSy was significantly lower than that on HSG. CONCLUSIONS 3D-TVS with HyFoSy allows accurate assessment of the position of Essure microinserts and tubal occlusion. It can be considered a safe, reliable, non-invasive alternative to HSG.

Abstract
At the present time, imaging guided renal biopsy is used to provide diagnoses in most types of primary and secondary renal diseases. It has been claimed that renal biopsy can provide a link between diagnosis of renal disease and its pathological conditions. However, sometimes there is a considerable mismatch between patient renal outcome and pathological findings in renal biopsy. This is the time to address some new diagnostic methods to resolve the insufficiency of conventional percutaneous guided renal biopsy. Nanotechnology is still in its infancy in renal imaging; however, it seems that it is the next step in renal biopsy, providing solutions to the limitations of conventional modalities.

Abstract
PURPOSE To compare sonohysterosalpingography (sono-HSG) with foam instillation (HyFoSy) versus saline solution (HyCoSy) in the evaluation of tubal patency. METHODS We prospectively enrolled 37 infertile women, scheduled for laparoscopy. The women were randomized into two groups: HyFoSy (group I) and HyCoSy (group II). The patients of both groups underwent laparoscopy with dye test. We assessed the diagnostic performance (sensitivity, specificity, and overall accuracy) of HyFoSy and HyCoSy, compared with laparoscopy and dye test, in the assessment of tubal patency. RESULTS Sono-HSG findings in tubal patency assessment obtained in the HyFoSy group were concordant with laparoscopic results in 94.4% of cases, with a sensitivity of 87.5% and a specificity of 100%, whereas in the HyCoSy group, concordance occurred in only 57.8% of examinations, with a sensitivity of 50% and a specificity of 66.6%. CONCLUSIONS HyFoSy allows a more accurate diagnosis of tubal patency compared with HyCoSy. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound 45:67-71, 2017.

Abstract
We present an overview of the common types of tubal patency tests, with a focus on hysterosalpingo-foam sonography (HyFoSy). Current evidence suggests that HyFoSy is an accurate alternative to X-ray hysterosalpingography (HSG) for outpatient tubal evaluation in women who are at low risk for tubal disease. It may be superior to saline hysterosalpingo-contrast sonography (HyCoSy) in excluding tubal occlusion. A hyperechogenic medium may enhance contrast visualization and enable clearer delineation of tubal anatomy. This may enhance confidence in the diagnosis of tubal patency, reduce false occlusion results, and improve the diagnostic yield of the test. It would be reasonable to deduce that HyFoSy would have similar performance characteristics as HyCoSy with other positive contrast agents. The available evidence supports the accuracy of HyFoSy compared to other forms of tubal investigation. We suggest a decision-making pathway based on the most current professional recommendations and available evidence. However, in this article, we do not provide a definitive exposition of the methods used for investigating tubal patency. Rather, we explore the contexts in which the various investigations are most and least suitable, and identify their strengths and limitations. Finally, we also discuss challenges encountered when performing tubal contrast sonography in clinical practice, including the problem of false occlusion results.

Abstract
OBJECTIVE To evaluate the efficacy of selective salpingography and tubal canalization (TC) procedure among patients diagnosed with proximal tubal occlusion (PTO). METHODS We conducted a retrospective cohort study on 61 sub-fertile patients aged 32.6 ± 4.9 years that were referred between the years of 2011 and 2013 with the diagnosis of PTO by prior hysterosalpingography. Patients underwent TC and were classified as bilateral PTO or unilateral PTO. Information regarding the patient's reproductive outcome within the 12 months following the procedure was collected by a telephone survey. RESULTS During the study period, 58/61 (95 %) patients underwent TC, resulting in bilateral open tubes in 54 patients (93.1 %). 53/58 (91.3 %) patients answered our survey. There were 23/53 (43.4 %) patients with a successful procedure who conceived after spontaneous or COH + IUI resulting in 15/23 live births (65.2 %). CONCLUSION Tubal canalization is a safe and minimally invasive procedure that can be used effectively to restore patency in a proportion of cases of PTO thus avoiding the need for expensive and invasive procedures such as assisted reproductive techniques.

Abstract
The objective of this study was to estimate the subsequent cancer risk of women after receiving hysterosalpingography (HSG) by conducting a nationwide retrospective cohort study. We identified a study cohort of 4,371 patients who had had a HSG examination and a comparison cohort of 17,484 women without HSG examination between 1998 and 2005. Both cohorts were followed up with until the end of 2010 to measure the incidence of cancer. The risk of developing cancer for patients with HSG was assessed using the Cox proportional hazard model. In the multivariate analyses, the HSG cohort did not have a significantly greater risk of cancer (Hazard Ratio [HR] = 1.02, 95% CI = 0.79-1.31) than the non-HSG cohort. The HR was highest for genital cancer (HR = 1.32, 95% CI = 0.77-2.25), followed by urinary system cancer (HR = 1.11, 95% CI = 0.23-5.40), and abdominal cancer not involving the GU system (HR = 1.04, 95% CI = 0.53-2.03), all of which were non-significant elevations. The cancer incidence rates, especially that for urinary system cancer, were increased in the HSG cohort, but the increase in cancer incidence was small and not statistically significant.

Abstract
OBJECTIVES To evaluate perception of pain during Fallopian-tube patency testing by hysterosalpingo-foam sonography (HyFoSy). METHODS In this cross-sectional study, 216 consecutive women presenting at a university fertility clinic for HyFoSy examination were included. Patients were instructed to take ibuprofen 1 hour before the procedure. Immediately after the procedure, patients filled in a questionnaire concerning discomfort or pain experienced during the process, including a visual analog scale (VAS) score for perception of pain. RESULTS The median VAS score for perception of pain during transvaginal ultrasound examination and during HyFoSy examination was 1.5 (95% CI, 1.2-1.7) and 3.6 (95% CI, 3.0-4.0), respectively. One-third of women reported that the level of discomfort or pain during HyFoSy examination was similar to that during the preceding transvaginal ultrasound examination and 48% of women considered HyFoSy examination to be neutral/unpleasant, but not painful. There was an inverse association between both patients' age and parity and the pain experienced. CONCLUSIONS HyFoSy examination is tolerated well and allows for reliable tubal patency testing without exposing the patient to ionizing radiation in an outpatient setting with a low technical failure rate.

Abstract
A state-of-the-art overview of the safety and side-effects of ExEm-gel for uterine cavity distension and ExEm-foam for tubal patency testing is presented. A literature search was carried out using PubMed, textbooks, pharmaceutical databases and reports of toxicity tests. Information on clinical use in humans and experiments in animal models was collected and grouped according to the following components: glycerol, hydroxyethyl cellulose and purified water; subjects included toxicity test, influence on sperm cells, oocytes, blastocyst development, uterine cavity distension, tubal patency testing, pain and obstetric applications. No unknown side-effects of gel or foam, or unexpected concerns about safety, were reported. More information than expected was available on the absence of effects of the components on various human tissues. Although it is difficult to prove that the search is complete, and it is possible that side-effects remain unreported, the combination of glycerol, hydroxyethyl cellulose and purified water is considered to be safe for intrauterine application and tubal patency testing, indicating an optimal risk-benefit ratio in clinical use. The safest strategy, however, is to restrict clinical examinations with gel and foam to the pre-ovulatory phase of the menstrual cycle.

Abstract
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.

Abstract
Background Tubal and uterine cavity diseases commonly compromise female fertility. At the present time, hysteroscopy, laparoscopy with chromopertubation and RX-Hysterosalpingography (RX-HSG) are widely accepted screening procedures enabling the effective assessment of both tubal patency and uterine cavity. Nevertheless, consistent evidence supports the reliability of Hysterosalpingocontrast sonography (HyCoSy) in uterine cavity and tubal patency investigation, as a part of the standard infertility work-up. This prospective study was aimed at evaluating the tolerability of the technique as well as the incidence of related side effects and complications in a large series of infertile patients. Methods Pain perception of 632 infertile women was measured by means of an 11-point numeric rating scale. Side effects and late complications were also recorded. Results The mean numeric rating scale was 2.15 ± 2.0 SD. Most of the patients (374/632, 59.17%) rated HyCoSy as a non-painful procedure, whereas 24.36% (154/632) women reported mild pelvic pain and 9.96% (63/632) classified the discomfort as “moderate”. Only 6.48% (41/632) of the patient population experienced severe pelvic pain. Fifteen (2.37%) patients required drug administration for pain relief. Twenty-six patients (4.11%) showed mild vaso-vagal reactions that resolved without atropine administration. No severe vaso-vagal reactions or late complications were observed. Conclusions HyCoSy is a well-tolerated examination and the associated vagal effects are unusual and generally mild. Consequently, we support its introduction as a first-line procedure for tubal patency and uterine cavity investigation in infertile women.

Abstract
BACKGROUND Hysterosalpingosonography has been suggested as a less invasive alternative to hysterosalpingography for detecting tubal occlusion among subfertile women. We aim to determine the diagnostic accuracy of hysterosalpingosonography and to compare it to hysterosalpingography. METHODS/DESIGN We will conduct a systematic review of diagnostic test accuracy. We will search Medline, Embase, Cochrane Library, Web of Science and Biosis, as well as reference lists of included studies and previous related review articles. Diagnostic studies that compared hysterosalpingosonography ± hysterosalpingography to laparoscopy with chromotubation in women suffering from subfertility will be eligible. Two authors will independently screen for inclusion, data extraction, and quality assessment. Methodological quality will be assessed using the Quality Assessment of Diagnostic Accuracy Study 2 tool (QUADAS-2). We will use SAS 9.3 (SAS Institute Inc., Cary, NC, USA, 2011) to program bivariate random-effects models, estimate pooled sensitivity and specificity with 95% confidence intervals and to generate summary receiver operating characteristics curves. We will perform sensitivity analyses to examine the effect of differences in techniques used for hysterosalpingosonography and in methodological quality of studies. DISCUSSION This systematic review will help to determine if hysterosalpingosonography is an adequate alternative screening test for diagnosing tubal occlusion. Accuracy of specific sono-HSG techniques may also be identified. TRIAL REGISTRATION This review has been registered at PROSPERO. The registration number is CRD42013003829.

Automated three-dimensional coded contrast imaging hysterosalpingo-contrast sonography: feasibility in office tubal patency testing. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2013; 41:328-335.

Abstract
OBJECTIVE To evaluate the feasibility of transvaginal hysterosalpingo-contrast sonography (HyCoSy) with new automated three-dimensional coded contrast imaging (3D-CCI) software in the evaluation of tubal patency and visualization of tubal course. METHODS Patients undergoing HyCoSy with automated 3D-CCI software were evaluated prospectively. First, to evaluate the feasibility of 3D visualization of tubal course, we performed consecutive volume acquisitions while injecting SonoVue contrast agent. We then performed conventional two-dimensional (2D) real-time HyCoSy to confirm tubal patency status by detection of saline and air bubbles moving through the Fallopian tubes and around the ovaries. We also evaluated visualization with CCI of the contrast agent around the ovaries, side effects and pain during and after the procedure, by visual analog scale (VAS) (ranging from 0 to 10, with 0 corresponding to no pain and 10 corresponding to maximum pain). RESULTS A total of 126 patients (252 tubes) underwent 3D-CCI HyCoSy followed by 2D real-time HyCoSy. According to the final 2D real-time evaluation, bilateral tubal patency was observed in 111 patients, bilateral tubal occlusion in four patients and unilateral tubal patency in 11 patients. The concordance rate for tubal patency status between the first 3D volume acquisition and the final 2D real-time evaluation was 84% and that between the second 3D volume acquisition and the final 2D real-time evaluation was 97%. A pain score >5 on VAS was recorded in 58% of patients during the procedure, but a pain score ≤ 5 was recorded in 85.7% of patients immediately after the procedure. CONCLUSIONS HyCoSy with automated 3D-CCI technology retains the advantages of conventional 2D HyCoSy while overcoming the disadvantages. 2D HyCoSy is highly observer-dependent and is only accurate in the hands of experienced investigators; by obtaining a volume of the uterus and tubes, automated 3D volume acquisition permits visualization of the tubes in the coronal view and of the tubal course in 3D space, and should allow less experienced operators to evaluate tubal patency status relatively easily.

Abstract
Objective To evaluate the effect of hysterosalpingo-contrast sonography (HyCoSy) on natural conception in the infertile patient. Methods We conducted a prospective observational study recruiting 180 patients admitted to Infertility Center of Ferrara University from January 2010 to February 2012. The essential inclusion criteria was the couple's desire to perform only diagnostic evaluation on infertility causes and to wait for natural conception before proceeding with further management. Couples were investigated with hormonal profile, semen analysis and HyCoSy. Expected time for spontaneous pregnancy was 180 days from HyCoSy. First datation sonography of pregnancy was used calculating time elapsed from HyCoSy at conception. Results Forty patients (22.2%) obtained spontaneous pregnancy within 6 months after HyCoSy. The mean of "conception time" was 75 days. The pregnancy rate was significantly higher in the first 30 days (45%) compared to other the months of observation (p<0.0005). Multiple linear regression analysis showed that maternal age and sterility duration proved independent variables in detecting the "conception time" after HyCoSy (t=3.742, p=0.001, t=2.371, p=0.02, respectively). Conclusion A possible beneficial effect of HyCoSy is feasible especially in the days following its execution. This temporal correlation supports its therapeutic use.

Abstract
AIMS To evaluate the feasibility and the reliability of hysterosalpingo-foam sonography (HyFoSy) using gel foam in the assessment of tubal patency. METHODS Nonrandomized, observational, academic and single-center study of 20 women being investigated because of subfertility and scheduled for a laparoscopy with chromopertubation. A detailed description of HyFoSy with a newly developed gel foam is given in the way it proved to be most efficient in our hands. The results of HyFoSy are compared to the data regarding tubal patency testing during laparoscopy by chromopertubation. RESULTS All 20 HyFoSy were technically successful. Four of the 40 tubes, 1 right tube and 3 left tubes, were not patent at HyFoSy (3 tubes with proximal block and 1 tube with distal block). There was a 100% agreement between tubal patency data according to HyFoSy testing and laparoscopic chromopertubation testing. CONCLUSION HyFoSy is both feasible and accurate in the diagnosis of tubal patency.

Abstract
PURPOSE To evaluate the efficacy, compliance, and cost effectiveness of sonohysterosalpingography (HyCoSy) compared with hysteroscopy for uterine cavity evaluation and compared with RX-hysterosalpingography (RX-HSG) for tubal patency determination. METHODS Three hundred and eight infertile patients underwent HyCoSy, hysteroscopy, and RX-HSG. We compared sensitivity, specificity, positive and negative predictive values (PPV and NPV), discomfort level, and cost of all three procedures. RESULTS Sensitivity, specificity, PPV, and NPV were higher for HyCoSy than for hysteroscopy but the differences were not significant. HyCoSy also has the same accuracy as RX-HSG. Pain perception and cost were higher for RX-HSG and hysteroscopy than for HyCoSy. CONCLUSIONS HyCoSy can be regarded as a procedure for initial evaluation of the uterine cavity and of tubal patency in infertile patients.
