The assessment of endometrial pathology and tubal patency: a comparison between the use of ultrasonography and X-ray hysterosalpingography for the investigation of infertility patients.
(1/50)
OBJECTIVES: The aim of the present study was to examine the role of hysterosalpingocontrast sonography (HyCoSy) as a screening test for endometrial and tubal pathology at the start of the infertility investigation protocol. METHODS: HyCoSy was compared with X-ray hysterosalpingography (HSG) for the assessment of the endometrial cavity and Fallopian tube patency. A total of 103 women with a history of at least 1 year's infertility were included. Each woman underwent both HyCoSy and HSG on the same day. Laparoscopy was performed in 43 cases. For HyCoSy examinations, saline was used for evaluation of the endometrial cavity and Echovist contrast medium to assess Fallopian tube patency. RESULTS: The concordance between HyCoSy and HSG for the presence of endometrial cavity pathology was 90%, but for tubal patency the concordance was lower (72%). HyCoSy classed more examinations of tubal patency as uncertain. HSG more frequently classified tubes as occluded. In the subset of patients in whom all three techniques were used, HSG and HyCoSy demonstrated a high concordance with laparoscopy (83% and 80%, respectively). The prevalence of occluded tubes according to laparoscopy as the reference standard was 13%. The two methods had a high negative predictive value for tubal disease (HSG, 94%; HyCoSy, 88%), and the positive predictive values were 47% and 75%, respectively. The detection rate for occluded tubes was 73% and 27%, and specificity 87% and 90%, respectively. CONCLUSIONS: Our data demonstrate that HyCoSy obtains similar information about the status of the endometrial cavity and Fallopian tube patency to that of HSG. It is possible that in some cases HyCoSy may replace HSG in order to select women with patent tubes who may be suitable for further infertility treatment without more invasive investigation. (+info)
Transvaginal salpingosonography for assessing tubal patency in women previously treated for pelvic inflammatory disease and benign ovarian tumors.
(2/50)
OBJECTIVE: The aim of this study was to evaluate the role of transvaginal salpingosonography in the assessment of tubal patency among women previously treated conservatively for pelvic inflammatory disease and surgically for a benign ovarian tumor. DESIGN: Twenty-two women were recruited for this study at the University Hospital of Oulu. Transvaginal salpingosonography was scheduled to be performed twice within a 3-month interval. X-ray hysterosalpingography was chosen as a reference method and was performed within 2 days of the second salpingosonography examination during the same menstrual cycle. Altogether, 31 Fallopian tubes were assessed with the second salpingosonography examination and X-ray hysterosalpingography. RESULTS: Twenty-nine Fallopian tubes were observed by both methods to be patent (i.e. 29 tubes by each method, but not necessarily the same tubes). An occlusion was diagnosed by each method in two tubes only, of which one appeared occluded by both methods, while one tube from each method appearing to be occluded was demonstrated to be patent using the other method. The agreement of transvaginal salpingosonography compared with X-ray hysterosalpingography was 94%, the sensitivity 50%, the specificity 97%, the positive predictive value 50% and the negative predictive value 97%. Two successive transvaginal salpingosonography examinations were performed in 18 patients with 27 Fallopian tubes. Disagreement was observed for only one tube. The agreement between these two examinations was 96%, the sensitivity 100%, the specificity 96%, the positive predictive value 67% and the negative predictive value 100%. The kappa coefficient was 0.78 (95% confidence interval 0.75-0.81). CONCLUSIONS: In conclusion, transvaginal salpingosonography can be used in patients with previous pelvic inflammatory disease and adnexal surgery due to its ease of use, reliability and low costs on an out-patient basis. Among these patients, tubal patency was a common finding. (+info)
Hysterosalpingo contrast sonography as a screening test for tubal patency in infertile women.
(3/50)
The most informative method for assessing tubal patency in subfertile women is laparoscopy-and-dye. This investigation, however, puts a large burden on services and a screening test is needed that identifies a high likelihood of occlusion. In our infertility programme we introduced hysterosalpingo contrast sonography for this purpose, operated entirely by ultrasonographers. A series of audits indicated that this innovation speeded the process of investigation by several weeks and reduced the number of laparoscopy-and-dye procedures by 75%. The negative predictive value was 89% and the positive predictive value was 44%. The main limitation of the method was the long period required for training, in those without extensive experience of vaginal ultrasonography. (+info)
The value of Chlamydia trachomatis antibody testing as part of routine infertility investigations.
(4/50)
Laparoscopy is considered the gold standard for the evaluation of tubal disease but it is an invasive and costly procedure. Chlamydia trachomatis antibody testing is simple and inexpensive and causes minimal inconvenience to the patient. Using the micro-immunofluorescence technique we assessed the significance of positive serology. There was a marked association between the titre and the likelihood of tubal damage. In the group with low titres (1 in 32) there was only a 5% incidence of tubal damage; however, there was a progressive increase in the incidence of tubal damage in those with higher titres. Twenty out of 57 patients with titres higher than 1 in 32 had tubal damage (35%). The difference between the two groups was statistically significant (P < 0.0001, chi(2) test). By using C. trachomatis antibody testing more widely it may be possible to reduce the number of laparoscopies performed. It should therefore become an integral part of the fertility work-up. (+info)
A technique for the evaluation of failed fallopian tube ligation with metal clips.
(5/50)
The evaluation of fallopian tubes after failed tubal ligation can be difficult because conventional histopathological techniques are unable to section the metal clips when in situ. Once the clips have been removed, any evidence of tube patency is lost. This report describes a technique of embedding and sectioning that enables sections to be made while the metal clips are still in situ. This is a modification of a method first described to embed mineralised bone and involves the use of plastic embedding and a diamond saw. Using this technique, a permanent record is made of the tube location and patency. (+info)
Air-contrast sonohysterography as a first step assessment of tubal patency.
(6/50)
We assessed the use of air as a sonographic contrast agent in the investigation of tubal patency by sonohysterography. We examined 115 women assessed for infertility. After saline sonohysterography, small amounts of air were insufflated, and the tubal passage of bubbles was monitored. In five patients (excluded from the results), cervical stenosis prevented the procedure. Ninety-one tubes (right side) and 86 tubes (left side) were definitively patent; 5 and 7, respectively, were probably patent; and 12 and 16, respectively, were nonvisualized. Nine patients had polyps, 3 had synechiae, and 2 had submucosal fibroids. None of the patients had infectious complications. Air-sonohysterography and laparoscopy with chromopertubation showed agreement in 79.4%. In 17.2% of patients, the tubes were considered nonvisualized by air-sonohysterography when they were patent. The sensitivity was 85.7% and specificity 77.2%. In conclusion, air-sonohysterography is a comfortable, simple, and inexpensive first line of tubal patency investigations yielding high accuracy.

Effects of methylene blue, indigo carmine solution and autologous erythrocyte suspension on formation of adhesions after injection into rats.
(7/50)
The aim of this study was to determine whether autologous erythrocyte suspension can be used as a dye for evaluation of tubal patency and whether it has any advantages over methylene blue or indigo carmine solutions. Reproductively healthy female nulliparous Wistar Albino rats (n = 30), aged 6 months, mass 165-195 g, were assigned randomly to three groups. Rats received a 1 ml i.p. injection of 5% (w/v) methylene blue solution (methylene blue group: n = 10), 5% (w/v) indigo carmine solution (indigo carmine group: n = 10) or 5% (v/v) fresh autologous erythrocyte suspension (autologous erythrocyte group: n = 10). At 4 weeks after injection, a small sterile opening was made in the peritoneal cavity of each rat. The cavity was rinsed once with TCM-199 to collect macrophages. The rinsed peritoneal contents were cultured overnight to evaluate macrophage activation. The peritoneal opening was expanded for evaluation of adhesion formation. Only one rat from the autologous erythrocyte group had intra-peritoneal adhesions (score 2), whereas all rats in the methylene blue group (score 1: n = 1; score 2: n = 4; score 3: n = 4; and score 4: n = 1) and seven rats in the indigo carmine group (score 1: n = 1; score 2: n = 2; score 3: n = 3; and score 4: n = 1) had intra-abdominal adhesions. Macrophage activity was observed in the cultured peritoneal contents collected from the methylene blue and indigo carmine groups but not from the autologous erythrocyte group. Adhesion formation could be due to macrophage activation caused by methylene blue and indigo carmine solutions. These results indicate that tubal patency can be observed by laparoscopy using autologous erythrocyte suspension. The results of this study are believed to be the first to indicate that a patient's own erythrocyte suspension could be used during observation of tubal patency by laparoscopy. However, further studies are required. (+info)
Three-dimensional power Doppler imaging in the assessment of Fallopian tube patency.
(8/50)
OBJECTIVE: The aim of the study was to evaluate the feasibility of three-dimensional power Doppler imaging (3D-PDI) in the assessment of the patency of the Fallopian tubes during hysterosalpingo-contrast sonography (HyCoSy). METHODS: Women attending the fertility clinic were offered a Fallopian tubal patency test as part of the initial investigation. Hysterosalpingo-contrast sonography using contrast medium Echovist was performed on 67 women. Findings on the two-dimensional (2D) gray-scale scanning and three-dimensional power Doppler imaging were compared. The first technique visualizes positive contrast in the Fallopian tube; the second demonstrates flow of medium through the tube. RESULTS: Contrast medium Echovist produced prominent signals on the 3D-PDI image. Free spill from the fimbrial end of the Fallopian tubes was demonstrated in 114 (91%) tubes using the 3D-PDI technique and in 58 (46%) of tubes using conventional HyCoSy. The mean duration of the imaging procedure was less with 3D-PDI, but the operator time which included postprocedure analysis of the stored information was similar. A significantly lower volume of contrast medium (5.9 +/- 0.6 mL) was used for 3D-PDI in comparison with that (11.2 +/- 1.9 mL) used for conventional 2D HyCoSy. CONCLUSION: Color coded 3D-PDI with surface rendering allowed visualization of the flow of contrast through the entire tubal length and free spill of contrast was clearly identified in the majority of cases. The 3D-PDI method appeared to have advantages over the conventional HyCoSy technique, especially in terms of visualization of spill from the distal end of the tube, which was achieved twice as often with the 3D technique. Although the design of the investigation did not allow the side effects of the two techniques to be compared, the shorter duration of the imaging and lower volume of the contrast medium used suggested that the 3D-PDI technique might have a better side-effect profile. The 3D-PDI technique allowed better storage of the information for re-analysis and archiving than conventional HyCoSy. (+info)
