Inter-Rater Reliability of Air/Saline HyCoSy, HyFoSy and HyFoSy Combined With Power Doppler for Screening Tubal Patency.

PURPOSE: To estimate the inter-observer reliability and agreement of offline analyses of three different ultrasound techniques for assessing tubal patency. METHODS: 100 tubes (n = 100) in 50 women were evaluated for tubal patency between November 2013 and July 2015 using ultrasound as index tests and laparoscopy as the reference standard. Three different ultrasound techniques were applied: two-dimensional grayscale ultrasound using air + saline as the contrast media (2D-HyCoSy); two- and three-dimensional grayscale ultrasound using foam as the contrast media (2 D/3D-HyFoSy); and the same technique but adding bi-directional power Doppler (2 D/3D-Doppler-HyFoSy). The videos containing full standardized exams using these three techniques were split into three parts, anonymized, encoded, randomized and reassessed in Nov. 2015 by two observers who assessed tubal patency using standardized criteria. These observers were blinded to any clinical information and each other's results. Proportions of observed agreement (po) and Cohen's Kappa (κ) including the 95 % confidence intervals (CI) were calculated. RESULTS: The inter-observer reliability/agreement in 2 D/3D-Doppler-HyFoSy (po = 0.99, κ = 0.95, 95 % CI: 0.93 - 0.97) was higher compared to 2D-air/saline-HyCoSy (po = 0.83, κ = 0.55, 95 % CI: 0.40 - 0.68) and 2 D/3D-HyFoSy (po = 0.92, κ = 0.67, 95 % CI: 0.54 - 0.76). CONCLUSION: The inter-observer reliability and agreement of the diagnosis of tubal patency evaluating stored videos are improved when foam and power Doppler are used during acquisition. Therefore, this technique may be preferred to minimize misclassification and misdiagnosis.

The Relations Between HSG Proven Tubal Occlusion, Stimulated Intrauterine Insemination and Pregnancy Rate.

BACKGROUND: Tubal factor infertility is one of the main causes of female infertility. Although its sensitivity is low, hysterosalpingography (HSG) is remains the first-line method for evaluating tubal patency. AIMS: To compare pregnancy rates in patients with HSG proven proximal or distal unilateral tubal occlusion, and unexplained infertility undergoing both controlled ovarian stimulation (COS) and intrauterine insemination (IUI). STUDY DESIGN: Case control study. METHODS: In total, 237 patients undergoing ovulation induction (OI) with gonadotropins and IUI were divided into two groups and evaluated. Study group consisted 59 patients with HSG proven unilateral tubal pathology, and 178 patients with unexplained infertility taken as control subjects. Cumulative pregnancy rate was the primary endpoint. RESULTS: Cumulative pregnancy rates after three cycles of OI and IUI were 15.25% in study group and 20.79% in control group. Pregnancy rates between two groups were not statistically significant. Although, pregnancy rates in patients with proximal tubal occlusion (21.8%) were higher than in those with distal tubal occlusion (7.4%), the difference was not statistically significant. CONCLUSION: Our study data shows that, regardless of the HCG proven occlusion area, COS and IUI might be a preferred treatment modality in patient with unilateral tubal occlusion.

Utility of Three-Dimensional Ultrasonography to Assess the Position of Essure Tubal Occlusion Device and Its Complications.

BACKGROUND: To determine the utility of three-dimensional (3D) sonography to control the position of hysteroscopic sterilizing device compared to hysterosalpingography (HSG). METHODS: A prospective observational study was carried out on 139 patients who underwent hysteroscopic tubal occlusion method between February 2012 and May 2013. Patients underwent 3D ultrasound scan to control device positioning, and they also underwent HSG as an additional control method. Comparison between both methods was carried out. RESULTS: In all, 17 (12.2%) devices were inserted due to a hydrosalpinx and 122 (87.8%) due to sterilization purposes. In 124 (89.2%) cases, sonography correlated completely to HSG findings. Sonography-positive predictive value was 89.5% to detect correct device positioning. Just 4 (2.8%) patients did not present complete tubal occlusion 3 months after device insertion; one of them presented device expulsion, 2 of them presented previous hydrosalpinx (tubal occlusion was confirmed after 6 months), and the last case rejected to undergo further controls but device seem to be effective. CONCLUSIONS: 3D sonography seems to be effective for the control of sterilization device positioning, but it also detects insertion complications and device migration. Further studies would be required to assess our findings and the role of sonography in case of hydrosalpinx.

Imaging in Infertile Female Patients Who Underwent Hysterosalpingography Investigation at Dhulikhel Hospital.

Background Fallopian tube and uterine abnormalities are the most common cause of female infertility, accounting for 30% of cases. Hysterosalpingography is the safe, minimal invasive radiographic technique for evaluation of uterine cavity and fallopian tubes defects. The purpose of the study was to assess the various uterine and tubal abnormalities leading to infertility Objective To assess the abnormalities in uterus and fallopian tubes detected on Hysterosalpingography (as causative factors of infertility in a tertiary care centre for proper decision making in treatment. Method This is the prospective cross sectional study done in department of radiology Dhulikhel hospital, Kathmandu University Hospital between January 2015 to January 2016 with complain of infertility. Hysterosalpingography was performed using ionic contrast medium (10-20 ml of 76% urograffin) under digital fluoroscopy. Radiographic films were obtained and analyzed. Demographic data and radiological findings were reviewed and the obtained data analyzed with SPSS version 16. Result Out of the total 100 patient, 75 had primary infertility while 25 had secondary infertility. The age ranged from 19 to 43 years with mean age of 27.75 years. Normal Hysterosalpingography findings were seen in 37% cases. Tubal abnormalities were seen in 34%, uterine abnormalities in 23% and both tubal and uterine abnormalities in 6% patients. The most common tubal abnormality detected on Hysterosalpingography was tubal block 75%. Out of the 30 patients who had tubal block, unilateral block was noted in 76.7% patients whereas bilateral block was noted in 23.3%. Hydrosalphinx was seen in 25% cases with tubal abnormality. Among the 29 cases with various uterine abnormalities, bicornuate uterus 9% was the most common abnormality Conclusion Hysterosalpingography is an easily available radiographic procedure that can demonstrate a wide variety of uterine and tubal abnormalities for the initial assessment of infertility which can avoid unnecessary and sometimes more aggressive procedures.

Evaluation and treatment of infertility.

Infertility is defined as the inability to achieve pregnancy after one year of regular, unprotected intercourse. Evaluation may be initiated sooner in patients who have risk factors for infertility or if the female partner is older than 35 years. Causes of infertility include male factors, ovulatory dysfunction, uterine abnormalities, tubal obstruction, peritoneal factors, or cervical factors. A history and physical examination can help direct the evaluation. Men should undergo evaluation with a semen analysis. Abnormalities of sperm may be treated with gonadotropin therapy, intrauterine insemination, or in vitro fertilization. Ovulation should be documented by serum progesterone level measurement at cycle day 21. Evaluation of the uterus and fallopian tubes can be performed by hysterosalpingography in women with no risk of obstruction. For patients with a history of endometriosis, pelvic infections, or ectopic pregnancy, evaluation with hysteroscopy or laparoscopy is recommended. Women with anovulation may be treated in the primary care setting with clomiphene to induce ovulation. Treatment of tubal obstruction generally requires referral for subspecialty care. Unexplained infertility in women or men may be managed with another year of unprotected intercourse, or may proceed to assisted reproductive technologies, such as intrauterine insemination or in vitro fertilization.

Diagnostic accuracy of sonohysterography vs hysteroscopy in benign uterine endocavitary findings.

OBJECTIVE: To compare diagnostic accuracy of sonohysterography vs hysteroscopy in patients with benign uterine endocavitary findings. PATIENTS AND METHODS: This retrospective study evaluated 202 patients submitted to sonohysterography after transvaginal ultrasound examination suspicious for uterine endocavitary findings. Cytological sample was taken and analyzed from the fluid used to distend the uterine cavity. Of 202 patients enrolled for this study, 86 patients underwent gynaecological surgery, of whom 77 were treated with operative hysteroscopy and 9 with other gynaecological surgical techniques. Statistical analysis was performed to evaluate diagnostic agreement between sonohysterography vs hysteroscopy and cytology vs histology. RESULTS: Diagnostic concordance between sonohysterography and hysteroscopy was significant (k value 0.87). The correlation between cytological and histological findings had a moderate level of concordance (k value 0.49). CONCLUSIONS: Sonohysterography provides a diagnostic accuracy as well as hysteroscopy, therefore, it could be considered an alternative procedure in the diagnosis of benign uterine endocavitary findings.

Comparison of Hysterosalpingography and Combined Laparohysteroscopy for the Evaluation of Primary Infertility.

Background Hysterosalpingography (HSG) is a useful screening test for the evaluation of female infertility. Laparoscopy has proven role in routine infertility work up but role of hysteroscopy in an infertile patient with normal HSG for additional information is a subject of debate. Hysteroscopy permits direct visualization of the cervical canal and the uterine cavity and thereby helping in the evaluation of shape, and cavitary lesion. Objective To detect uterine abnormalities in infertile women by various approaches i.e. HSG and hysteroscopy and evaluating the role of combining hysteroscopy with laparoscopy for the evaluation of tubo-uterine factor for primary infertility. Method One twenty eight infertile women were evaluated and HSG was performed as a basic test for evaluation of tubes and uterine cavity. Women were subjected to combined laparoscopic and hysteroscopic examination on evidence of HSG abnormalities. In absence of any HSG abnormality, women were subjected to ovulation induction for three to six months and if they did not conceive during this period they were undertaken for combined laparo-hysteroscopic evaluation. Result The positive predictive value of HSG for detecting the intrauterine abnormalities was 70% among 126 patients where the hysteroscopy could be performed successfully. The diagnostic accuracy of HSG for intrauterine abnormalities revealed false negative rate of 12.96%. The most frequent pathologies encountered by laparoscopy were tubal and/or peritoneal and were found in 68% (87/128) of women. Total 64.06% infertile women had some abnormality on laparoscopy. This detection rate has been increased from 64.06% to 71.86% on including the concomitant hysteroscopy. Conclusion HSG is a good diagnostic modality to detect uterine as well as tubal abnormalities in infertile patient. HSG and hysteroscopy are complementary to each other and whenever the patient is undertaken for diagnostic laparoscopy for the infertility, hysteroscopy should be combined to improve the detection rate of abnormalities especially in communities where there is enormous risk of pelvic infection.

Experience improves performance of hysterosalpingo-contrast sonography (HyCoSy): a comprehensive and well-tolerated screening modality for the subfertile patient.

PURPOSE: To investigate the clinical observations, provider experience, safety, and tolerance of the hysterosalpingo-contrast sonography (HyCoSy) procedure. MATERIALS AND METHODS: A retrospective study design in which data was collected from ninety-six subfertile women who underwent the HyCoSy procedure at the University of Louisville over a 16-month interval. RESULTS: Ninety-six HyCoSy procedures were performed by a single investigator and contained complete records for review. The authors observed significant decreases in the quantities of saline and air utilized per procedure over time (p < 0.0001 and p = 0.0001). Results from the HyCoSy studies were more often non-diagnostic or non-patent in women with a body mass index (BMI) > 30. Reported pain scores did not statistically differ over the course of the study interval. There were no procedure-related complications noted. CONCLUSION: The HyCoSy procedure is a timely and minimally invasive study that can be implemented in an office setting with minimal prior operator experience that improves over time.

CT appearance of the pelvis after Cesarean delivery--what is considered normal?

OBJECTIVE: To describe the normal computed tomography (CT) appearance of the pelvis after uncomplicated Cesarean section (C-section). PATIENTS AND METHODS: Pelvic CT examinations of 31 patients after uncomplicated C-section were reviewed. RESULTS: Higher postoperative day (POD) correlated well with decreases in the uterine long axis and endometrial width but did not correlate to scar width. Full thickness defect of the uterine wall was revealed in 48% of patients. Small volumes of intrauterine gas presented in half of patients at POD 1-26. Free pelvic fluid appeared in 74%. Pelvic collections were rare and small. CONCLUSION: There is wide variability in pelvic CT appearance following uncomplicated C-section.

Transvaginal hydrolaparoscopy for diagnosis of tubal infertility.

OBJECTIVE: Infertility problem affects more than 70 million couples worldwide, 5-15% of which are couples in their reproductive age. Less and less invasive endoscopic methods like transvaginal hydrolaparoscopy have been developed by technological progress. This method enables not only precise identification, but is now increasingly used for treatment of tubal and peritoneal factor pathology, which cause approximately 35 per cent of female infertility. AIM: Evaluation of transvaginal hydrolaparoscopy (HLTV) usefulness for diagnosis of tubal infertility comparing to standard laparoscopy and hysterosalpingography (HSG). RESULTS: In evaluation of patent fallopian tubes results of HLTV and HSG examinations are coincide in 87%, while obstruction diagnosed in HSG is confirmed only in 37% during HLTV examination. Transvaginal hydrolaparoscopy and HSG have similar sensitivity and specificity in diagnosis of hydrosalpinx, which is up to 100% . In comparison with HLTV histerosalpingography is less effective in evaluation of peritubal dilatations and adhesions. Both laparoscopic surgery and transvaginal laparoscopy have the same high sensitivity in diagnostics of the fallopian tubes patency and hydrosalpinx, which is up to 100%. In evaluation of peritubal adhesions and dilatations the results are very similar. CONCLUSIONS: 1. HLTV is a highly useful method in evaluation of the fallopian tubes pathologies which is significantly more sensitive than HSG in evaluation of such lesions as peritubal adhesions and obstructed fallopian tubes. 2. HLTV is as effective as laparoscopy in evaluation of patency and lesions of the fallopian tubes. 3. HLTV is a less invasive method, much better tolerated than laparoscopy and more suitable for the group of overweight patients. 4. Final assessment of HTLV technique will be possible following performance of a greater number of studies, where the foregoing conclusions present only initial observations.

Uterine cavity assessment prior to IVF.

Approximately 15% of couples are affected with subfertility, of which up to 20% remain unexplained. Uterine cavity abnormalities can be a contributing cause of subfertility and recurrent implantation failure. Uterine cavity assessment has been suggested as a routine investigation in the evaluation of subfertile women. Traditionally, hysterosalpingography has been the most commonly used technique in the evaluation of infertility. Transvaginal ultrasound scan allows visualization of the endometrial lining and cavity, and has been used as a screening test for the assessment of uterine cavity. Abnormal uterine findings on a baseline scan can be further evaluated with saline hysterosonography, which is highly sensitive and specific in identifying intrauterine abnormalities. Hysteroscopy is considered as the definitive diagnostic tool to evaluate any abnormality suspected on hysterosalpingography, transvaginal ultrasound scan or saline hysterosonography during routine investigation of infertile patients. Minimally invasive hysteroscopes have minimized the pain experienced by patients during the procedure and made it feasible to use hysteroscopy as a routine outpatient examination. Following recurrent IVF failure there is some evidence of benefit from hysteroscopy in increasing the chance of pregnancy in the subsequent IVF cycle, both in those with abnormal and normal hysteroscopic findings. Various possible mechanisms have been proposed for this beneficial effect, but more randomized controlled trials are needed before its routine use in the general subfertile population can be recommended.

Hysterosalpingography in the investigation of women requesting reversal of sterilization. Should it play a role?

OBJECTIVE: To evaluate the role of hysterosalpingography (HSG) in the investigation of women requesting reversal of sterilization (ROS). STUDY DESIGN: A prospective, cohort study at a university-affiliated, tertiary fertility clinic. All women proceeding to surgery were investigated with HSG in addition to other routine screening. Findings from HSG were tabulated to document the prevalence of abnormalities and correlated with histologic findings in resected tubal segments. RESULTS: One hundred sixteen women of 166 referred for ROS underwent HSG during the initial evaluation. HSG depicted abnormal tubal images in only 2 cases (1.7%) and abnormal uterine images in 15 (12.9%) cases. In the cases of abnormal tubal findings, there was no association with histologic findings. The specificity of HSG as a diagnostic screening tool was 90%; however, the small number of cases with abnormal histology prevented calculation of an accurate estimate of sensitivity of HSG as an investigative tool before ROS. A less invasive method of imaging the uterus, such as a vaginal ultrasound, may provide more valuable information in evaluating the future fertility outcome in these women. CONCLUSION: The prevalence of abnormalities of the proximal oviductal segment identified by HSG is too low to warrant the routine use of HSG as a diagnostic tool.

Follow-up of successful bilateral placement of Essure microinserts with ultrasound.

OBJECTIVE: To evaluate the reliability of pelvic X-ray and transvaginal ultrasound to localize Essure microinserts (Conceptus, San Carlos, California) after successful placement in both fallopian tubes 3 months after placement. DESIGN: Prospective, observational study. SETTING: Gynecology departments at two teaching hospitals. PATIENT(S): One hundred eighty-two patients who underwent hysteroscopic sterilization by placement of Essure microinserts between August 2002 and August 2004. INTERVENTION(S): Transvaginal ultrasound, pelvic X-ray, and hysterosalpingography (HSG) 3 months after sterilization with Essure. MAIN OUTCOME MEASURE(S): Transvaginal ultrasound confirmation of correct localization of microinserts after a 3-month follow-up. RESULT(S): In 150 of 182 patients, confirmation of successful bilateral placement of two microinserts (300 devices) was possible. In 9 patients it was not possible to identify both devices with ultrasound, or there was doubt about the extension of the device through the uterotubal junction. The other 291 devices were identified as being in a good position. CONCLUSION(S): Hysterosalpingography at the 3-month follow-up after successful placement of Essure microinserts can be replaced by transvaginal ultrasonography. A 3-month follow-up with HSG after the Essure procedure is only required after unsatisfactory placements. In those patients in whom transvaginal ultrasonography cannot confirm satisfactory localization, a complementary pelvic X-ray should be performed.

A prospective comparative study between hysterosalpingography and hysteroscopy in the detection of intrauterine pathology in patients with infertility.

AIM: To investigate the accuracy of hysterosalpingography (HSG) in comparison to hysteroscopy in the detection of intrauterine pathology in patients with infertility, where hysteroscopy is the gold standard. METHODS: A prospective, comparative study included 336 patients undergoing both HSG and diagnostic hysteroscopy. Main outcome measures were sensitivity, specificity, positive and negative predictive value, and accuracy rate of HSG. RESULTS: Intrauterine abnormalities were shown on HSG in 286 patients and confirmed in 200 at hysteroscopy. Contrarily intrauterine lesions were detected by hysteroscopy in 4 out of 50 patients in whom HSG were normal. The most common intrauterine finding of 336 patients on hysteroscopy were intrauterine adhesions (IUA) (74), followed by endometrial polyps (56), and submucous myoma, 26 patients. Statistical analysis revealed that HSG in the detection of intrauterine pathology had a sensitivity of 98.0%, specificity of 34.9%, positive predictive value of 69.9%, negative predictive value of 92.0%, and accuracy rate of 73.2% with false-positive and false-negative rates of 30.1% and 8.0%, respectively. The common incorrect diagnoses of HSG were misdiagnosing a condition of cervical stenosis as severe IUA in 24 patients, endometrial polyps as submucous myoma in 22 out of 50 patients, and submucous myoma as endometrial polyps in 12 out of 72 patients. CONCLUSIONS: Hysterosalpingography is still a useful screening test for the evaluation of the uterine cavity. If a hysterogram demonstrates intrauterine abnormalities, hysteroscopy should be considered to make a definite diagnosis and treatment. Both procedures should be complementary to each other.

Tolerability of the mini-pan-endoscopic approach (transvaginal hydrolaparoscopy and minihysteroscopy) versus hysterosalpingography in an outpatient infertility investigation.

OBJECTIVE: To compare the acceptance and tolerability of the mini-pan-endoscopic approach (transvaginal hydrolaparoscopy [THL] combined with minihysteroscopy) versus hysterosalpingography (HSG) for evaluating tubal patency and the uterine cavity in an outpatient infertility investigation. DESIGN: Randomized controlled study. SETTING: University hospital. PATIENT(S): Twenty-three infertile patients without obvious pelvic pathology. INTERVENTION(S): Women were randomly divided into two groups. One group underwent minihysteroscopy and THL with tube chromoperturbation as first investigation and HSG within the following 7 days, while in the other group the investigation sequence was inverted. Women reported pain experienced before and at the end of procedures. MAIN OUTCOME MEASURE(S): Mean duration of procedures, level of pain experienced, diagnostic agreement about tubal patency and uterine cavity normality. RESULT(S): THL and minihysteroscopy took significantly more time but was significantly less painful than HSG. Regarding tubal patency, in 95.5% of cases THL agreed with HSG. In one case, HSG diagnosed a bilateral obstruction of tubes, whereas at THL a bilateral spreading of methylene blue was seen. Agreement on intrauterine pathologies between minihysteroscopy and HSG was poor (43%); the number of intrauterine abnormalities found at hysteroscopy was significantly greater than at HSG. CONCLUSION(S): THL in association with minihysteroscopy provided more information and was better tolerated than HSG in an outpatient infertility investigation.

[Which initial tests should be performed to evaluate meno-metrorrhagias? A comparison of hysterography, transvaginal sonohysterography and hysteroscopy]. / Quelle exploration réaliser de première intention face aux méno-métrorragies? A propos d'une série prospective comparant l'hystérographie, l'hystérosonographie et l'hystéroscopie.

OBJECTIVE: Evaluate the feasibility and the value of hysterography, sonohysterography and hysteroscopy for investigation of abnormal uterine bleeding. Method. Longitudinal blind study of thirty-eight patients consulting for abnormal uterine bleeding during pre- and post menopause. All patients underwent an hysterography and transvaginal sonohysterography, in random order, followed by an hysteroscopy with histological sample. The results were compared with the histo-pathological examination that was used for reference diagnosis. Statistical study of sensitivity, specificity and Positive and Negative Predictive Value (PPV-NPV) of each investigation; rate of agreement by the coefficient of Kappa. RESULTS: The hysterography offers a PPV of 83% and a NPV of 100%. The interpretation errors were associated with the simple mucous hypertrophy interpreted as "hyperplasy". The limits correspond to a contrast agent allergy. The sonohysterography had a VPP of 89% and a VPN of 100%. The false positive is due to the difficulties of distinguishing the clots from the polyps. The limits correspond to the difficulties of cervix catheterization (13%). As regards the hysteroscopy, the VPP was 81.5% and the VPN of 75%. The interpretation mistakes were associated with mucous hypertrophy and the hyperplasy. CONCLUSIONS: The most useful examination for abnormal uterine bleeding, in the first instance, is transvaginal sonography with saline instillation. A complement by Doppler study would probably make it possible to limit the false positives.
