RESUMO
STUDY OBJECTIVE: To evaluate the accuracy of the "Parryscope" and "flow" techniques for hysteroscopic assessment of tubal patency. DESIGN: Prospective randomized clinical trial. SETTING: From May to October 2019, women with subfertility undergoing laparoscopic and hysteroscopic surgery at the Medical University of Vienna were invited to participate in the study. The primary outcome was accuracy of Fallopian tube patency relative to the gold standard of laparoscopic chromopertubation. PATIENTS: Sixty women with subfertility. INTERVENTIONS: Hysteroscopy with either the "Parryscope" or the "flow" techniques for tubal assessment, directly followed by laparoscopy with chromopertubation. MEASUREMENTS AND MAIN RESULTS: Hysteroscopic prediction of fallopian tube patency was possible in a statistically significant manner in both study groups (p <0.05). The Parryscope technique achieved higher sensitivity (90.6%, 95% CI: 61.7-98.4) and specificity (100%, 95% CI: 90.0-100.0) than the flow technique (sensitivity: 73.7%, 95% CI: 48.8-90.9 and specificity: 70.7%, 95% CI: 54.5-83.9). CONCLUSION: Using the Parryscope technique to determine if air bubbles traverse the ostia can provide valuable additional information during hysteroscopy and is more accurate in predicting fallopian tubal occlusion than the flow method.

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.

OBJECTIVE: To describe our simplified technique for falloposcopic tuboplasty (FT) and demonstrate its principle and results. DESIGN: A step-by-step description of the technique and demonstration of its principle using a clay model. SETTING: Private infertility clinics in Osaka and Tokyo operated by 10 physicians. PATIENT(S): A total of 431 infertile women with a diagnosis of unilateral or bilateral proximal tubal occlusion (6 cm from the uterotubal ostia), between October 2013 and February 2019 were included. These patients underwent routine work-ups for infertility, including a semen analysis, hysterosalpingography, antimüllerian hormone, basal luteinizing hormone/follicle-stimulating hormone and prolactin concentrations during menstruation, postcoital test in the periovulatory period, and estradiol and progesterone concentrations in the middle of the luteal phase. Physicians performed hysterosalpingography to evaluate tubal patency and uterine shape. Saline infusion sonography was not conducted because it does not accurately identify regions of tubal occlusion and/or stenosis. INTERVENTION(S): The principle of our simplified technique for FT is that a hole is located at the side of the FT catheter tip. Therefore, the balloon and fiberscope move away from the catheter line (Fig. 1). The uterotubal ostium is located at the tip-end of the triangle of the uterine cavity. When a balloon is inserted while visualizing the uterotubal ostium at the nearest position to the ostium, the balloon hits the uterine wall. When a balloon is inserted 5-10 mm from the uterotubal ostium without visualization, the balloon may be easily placed in the ostium through its convex angle, allowing it to slide into the uterine wall (Figs. 2 and 3). Step 1: Confirm anteflexion or retroflexion of the uterus by ultrasound. Step 2: Confirm the direction of the uterotubal ostia by hysteroscopy. Step 3: Adjust the angle of the FT catheter according to steps 1 and 2, insert the catheter into the end of the uterus, pull it back 5-10 mm (without visualizing the uterotubal ostia), and then fix it to the forceps. Catheter placement away from the tubal ostium is confirmed by the residual length of the moving part of the catheter. An attending instructor should ask the operator about the feeling of rigidity when the catheter does not advance and then suggest whether to proceed or stop. In the latter case, the catheter is not moved, saline is infused for 1 minute for lubrication, the balloon is pulled back using the fiberscope to remove the bunching of the balloon, and balloon pressure is changed as follows: 6â8â6â10â6 mmHg. Our institutional review board stated that approval was not required because the video describes the technique of our routine procedure. MAIN OUTCOME MEASURE(S): A description of the FT technique using a clay model and a demonstration of its application in our clinic. RESULT(S): The average operative time was 15.4 minutes, and the clinical pregnancy rate was 24.4% (natural conception and intrauterine insemination without in vitro fertilization). No significant differences were observed in the operative time or pregnancy rate among physicians. Approximately 17 FT procedures may be performed using one fiberscope. CONCLUSION(S): Our simplified technique, which was described and demonstrated in this video article, is a feasible and practical approach for performing FT. It provides excellent cost performance by saving fiberscopes. The most important point is "Introduce the balloon and fiberscope 5-10 mm away from the uterotubal ostia without visualizing it." To facilitate learning this technique, we recommend watching the video and then practicing FT without searching for the uterotubal ostia. Physicians master FT without any assistance by an attending instructor in ≤3 attempts.

OBJECTIVE: To demonstrate a novel approach to office tubal patency assessment through infusing air into saline during flexible office hysteroscopy. We also provide data addressing pain and patient experience relative to hysterosalpingography (HSG). DESIGN: Video presentation of clinical technique with supportive crossover data (Canadian Task Force classification II-1). Its University of Mississippi Medical Center Institutional Review Board protocol number is 2013-0230. SETTING: Academic hospital. PATIENT(S): Women undergoing office hysteroscopy and ultrasound, with a subset also having HSG. INTERVENTION(S): Air infusion into saline during office hysteroscopy. MAIN OUTCOME MEASURE(S): The focus is on demonstrating how the technique appears and is performed, with supplemental Likert data addressing subjective pain and preference relative to HSG. RESULT(S): When performed as described, this office technique has 98.3%-100% sensitivity to tubal occlusion and 83.7% specificity. The gentle technique is central to accurate outcomes, which is facilitated through use of a small-caliber (<3 mm), flexible hysteroscope and avoiding uterine overdistention. Patients are far more likely to report maximum discomfort with HSG. Among patients who also had HSG, 92% somewhat or strongly prefer hysteroscopic assessment. Also, 96% of patients reporting maximum discomfort with HSG had mild to no discomfort with the described technique. CONCLUSION(S): Air-infused saline at flexible office hysteroscopy can accurately, gently, and rapidly assess tubal patency. Coupled with strong patient preference for this technique over HSG, it is a promising option for evaluating fertility. CLINICAL TRAIL REGISTRATION NUMBER: NCT02005263.

Laparoscopic chromopertubation is considered "gold standard" for checking the tubal patency. Foley catheter is frequently used for blue dye during chromopertubation. Complications associated with the intra-uterine use of Foley catheter are infrequent. The mean normal capacity of the uterine cavity is about 9 ml, and an inflation of up to 30 ml (e. g. during thermal balloon ablation procedures) is considered safe. We report a uterine rupture in a 36-year-old woman undergoing laparoscopic chromopertubation due to primary infertility. Thirteen years ago, the patient had three consecutive laparotomies because of appendicitis, peritonitis and retroperitoneal abscess. For the present laparoscopy, the Foley catheter (Nelaton, charier 10, balloon 5 ml) was used. The first blocking of the balloon with 3.5 ml saline was insufficient; however after inflating with 5 ml, a rupture of the uterine fundus occurred. The balloon remained intact and both tubes appeared patent. The myometrium was sutured and the postoperative course was uneventful. We presume that-in the present case-the expansive capacity of the uterine wall may have been reduced after the series of severe pelvic inflammations. Nevertheless, if using a Foley catheter for the chromopertubation, the optimal pressure for its intrauterine fixation needs still to be determined.

OBJECTIVE: To compare the ability of four chromotubation techniques to generate and maintain intrauterine pressures in the diagnosis of proximal tubal obstruction. METHODS: Sixteen extirpated uteri were used for this study. A pressure catheter was placed through the fundus into the endometrial cavity. Three cannulas were evaluated: 1) the Cohen cannula with hold and no-hold techniques, 2) the BARD cervical cannula (dual intrauterine and intracervical balloons), and 3) the Harris-Kronner uterine manipulator-injector catheter with an intrauterine balloon. Intrauterine pressures were monitored while warm saline was infused. The studies were performed with the tubes obstructed, and measurements of peak attainable intrauterine pressures were recorded. Data were analyzed by t test, with significance set at P < .05. RESULTS: Peak intrauterine pressures for the four groups were as follows: 1) Cohen cannula, not holding, 40.7 +/- 5.1 mmHg; 2) Cohen cannula, holding in place, 63.6 +/- 5.3 mmHg; 3) BARD cannula, 112.4 +/- 3.5 mmHg; and 4) Harris-Kronner cannula, 106.3 +/- 4.3 mmHg. The BARD and Harris-Kronner cannulas achieved significantly higher intrauterine pressures than either method of using the Cohen cannula (P < .001). There was no statistically significant difference between the BARD and Harris-Kronner cannulas. CONCLUSION: Significant differences in achievable intrauterine pressures were demonstrated among catheters in our in vitro model. Based on these findings, we believe that the BARD, Harris-Kronner, or other intrauterine balloon-type cannula should be used before diagnosing proximal tubal obstruction.

Using a pediatric Foley catheter, salpingography, CO2 insufflation, hydrotubation, pelvic pneumography, pelvic pneumoperitoneum for laparoscopy, and pneumohysterosalpingography were performed in more than 1000 cases. The Foley catheter technic was fully described and the advantages outlined. In general, the Foley catheter proved to be a simple and atraumatic technic, eliminating some of the difficulties associated with the use of the metal cannula.

OBJECTIVE: Evaluation of selective salpingography for diagnosis and treatment of tubal injection failure during hysterosalpingography (HSG). DESIGN: Prospective study. SETTING: Obstetrics and Gynecology Department, University of Genoa (Italy)--tertiary care. PATIENTS: One hundred eighty infertile women with unilateral or bilateral proximal tubal injection failure during HSG were submitted to the procedure. INTERVENTION: Under fluoroscopy, a 4.5-F nylon catheter (3-F tip) was inserted into the ostium with or without the aid of a J-shaped, coaxial, angiographic guide wire, and 2 to 3 mL of contrast medium were injected. The procedure lasts 20 to 30 sec/tube. MAIN OUTCOME MEASURES: Of 155 tubal ostia, 145 (94.2%) were catheterized. RESULTS: Of the 146 catheterized tubes, 110 (75%) were rendered patent. Of the others, 21 (14.3%) presented hydrosalpinx or distal obstructions, and isthmic obstruction was present in 5 (3.4%). Patency of at least one tube was achieved in 82 (81.2%) of the 101 catheterized women; 8 conceived spontaneously and 11 after gamete intrafallopian transfer to the recanalized tube. CONCLUSIONS: During HSG, selective salpinography can be performed when proximal injection failure is observed to determine its cause or to restore patency.

Rapid progress has been made in the last 10 years regarding minimally invasive access to the human fallopian tube. Coaxial catheter systems are being used with hysteroscopy, fluoroscopy, ultrasonography, and tactile sensation to cannulate the fallopian tube transcervically with consistent success. Uterotubal obstruction viewed at the time of hysterosalpingogram can often be successfully cannulated with intrauterine pregnancies resulting. This review surveys all available published series of transcervical tubal cannulation with discussion of methodology, success in establishing patency, and the resultant pregnancy rates. It also describes how this technology has been applied to the intratubal deposition of gametes and embryos, direct visualization of the tubal epithelium, (falloposcopy), and contraception. Collectively, these techniques are defining tubal pathology more precisely, allowing us to prescribe the proper therapy.

Tubal patency was studied in 17 sterile women by means of colour-coded duplex sonography (CCDS) with local injection of an ultrasonic contrast medium. The results were compared with a conventional hysterosalpingogram. CCDS demonstrated all the soft tissues and their mobility. The ultrasonic contrast medium was SH U 454 (Schering). The colour signals generated by the air bubbles makes it possible to demonstrate tubal patency on both sides. The combination of an ultrasonic contrast medium and CCDS provides a simple, rapid, accurate and safe method for demonstrating tubal patency. Tubal patency can be demonstrated in the presence of anatomical complications and requires only a small amount of contrast medium.

A linear everting catheter in combination with a 0.5-mm microendoscope enables the visualization of the tubal lumen. In 35 sterility patients, diagnostic tuboscopies were performed. Physiological and pathological results of tubal mucosa are described. Tuboscopy is a main tool in the diagnosis of the tubal factor. First steps are taken to use tuboscopy not only for diagnostic but also for therapeutic reasons. Yet, the role of this technique in cases of tubal pregnancies cannot be evaluated.

It is considered that one out of five couples present a transitory problem of infertility during their reproductive life and the most frequent cause is the tubarian pathology; from these, the proximal obstruction occupies between 25 and 30% of the cases. Unfortunatelly, the conventional method use to study tubarian patency such as histerosalpingography or the direct observation by laparoscopy and selective chromotubation, frequently do not allow to differentiate between an insufficient filling of the tubes, tubarian spasm or a true mechanical obstruction. There are certain selective tubarian cannulation techniques, for example, the catheterism with hysteroscopic guidance which is extremely usefull in the diagnosis of tubarian patency or in the confirmation of partial or total proximal tubal disease. The procedure permits to diagnosticate precisely the tubarian obstruction and also if it is due to the presence of a true pathology or simply functional, or secondary to a tubarian spasm; besides it also works as a therapeutic procedure since in the first case permits the lysis of laxe adherencies and the removal of the amorfus material that obstructs the tube and permits the catheterization. The present study determines the utility of catheterization of the tubarian ostium by hysteroscopy with laparoscopic control using the Novy (Cook, Ob/ Gyn) catheter in patients with infertility problems due to proximal obstruction of one or both of the fallopian tubes, to confirm or discard the presence of a pathological obstruction. The results are evaluated in terms of tubarian permeability and the pregnancy rate after the procedure.

UNLABELLED: BUT: Introducing a new sonographic method for evaluation the patency of fallopian tubes. MATERIAL AND METHODS: Transvaginal hysterosalpingosonography (HSSG), using chlorocid as a contrast material was performed in 52 infertile women, 12 of with after ectopic pregnancy. RESULTS: Transvaginal hysterosalpingosonography showed as patent 24 fallopian tubes and 68 obturated. LSC and/or HSG pointed 30 patent and 62 obturated. Compared to LSC and HSG, transvaginal HSSG showed 100% sensitivity and 88% specificity. CONCLUSIONS: This investigation revealed the good diagnostic value of HSSG with chlorocid as an easy and not expensive method for the evaluation of the patency of fallopian tubes.

OBJECTIVE: To assess histologic damage and functional impairment following coaxial tubal catheterization. DESIGN: Prospective randomized controlled study. SETTING: Research laboratory. PATIENT(S): Ninety-two female New Zealand rabbits. INTERVENTION(S): Tubal cannulation and mating. MAIN OUTCOME MEASURE(S): Rabbits randomized for placement of unilateral catheter and guide wire (group 1), unilateral catheter and guide wire plus falloposcope (group 2), and catheterization as in group 1 or 2 but using a cage catheter (groups 3 and 4, respectively). A fifth group consisted of rabbits with tubal perforations. Rabbits were killed at 2 or 4 weeks after catheterization or after mating. The sixth group consisted of only control rabbits. RESULT(S): Only one catheterized tube in groups 1 and 3 showed inflammation, fibrosis, or edema. None of the tubes manifested ciliary loss. Serosal tubal adhesions were identified in two tubes in group 1, in one in group 3, in three tubes in group 5, and one in the control group. The nidation index in control and nonperforated catheterized tubes ranged from 72%-95% (not significant). Nidation index in tubes unintentionally perforated was 81%. CONCLUSION(S): Catheterization of the uterotubal junction and fallopian tube in rabbits does not cause long-term tubal damage or impair tubal function.

OBJECTIVE: Since 1990 we have undertaken a trial to evaluate if TVS, even without contrast media, could diagnose tubal patency. MATERIALS AND METHODS: A detailed description of the technique is given. Two hundred and seventy-three patients underwent sonosalpingography in our department in the period 1990-1993. The sonographic findings were matched in 43 cases to hysterosalpingography and in 55 cases to laparoscopy. RESULTS: Tubal patency was demonstrated in 218 patients (80.5%), monolateral patency in 41 (15.1%) patients and bilateral tubal occlusion in 12 (4.4%) patients. In the 43 patients undergoing hysterosalpingography, discordance between the two examinations was observed in five cases (11.6%). However, only six out of 86 salpinxes had different results (6.9%). In only one case was total discordance observed. In three out of four other cases the difference was due to patency diagnosed at SSG and occlusion at HSG. Of the 55 patients undergoing laparoscopy 12 cases (21.8%) had discordant results. Complete discordance was observed in two cases while in ten cases one salpinx had a different patency report. The discordance goes to 12.7% when we take into account all the salpinxes evaluated. CONCLUSION: Sonosalpingography gives very similar results to hysterosalpingography and may be used on clinical basis for tubal patency evaluation.

There will be demonstrated a method in order to contrast the cavum uteri and the uterine tubes by means of a x-ray TV amplifier in combination with simultaneous intrauterine pressure monitoring. We could demonstrate that measuring the intrauterine pressure during continuous flow of radio-opaque material at hysterosalpingography results in additional informations about tubal patency.
