Vaginal Ultrasonography versus colpo cysto urethrography in the evaluation of female urinary incontinence
Acta Obstetricia et Gynecologica Scandinavica, 1994Co-Authors: Lone Mouritsen, Charlotte StrandbergAbstract:To compare the information of bladder neck suspension given by colpo-cysto-urethrography (CCU) and Vaginal ultra-sonography (US), 44 women with various grades of incontinence were examined by both methods. The criteria for evaluation of incontinence for each method were applied on both procedures. CCU-diagnoses of type of bladder neck descent were compared as well as US-measurements of bladder neck position and mobility in relation to the symphysis pubis during rest, Valsalva and withholding. The interobserver agreement of diagnoses was 58%, which is comparable to interobserver agreement for CCU. The measurements of bladder neck suspension by bladder to symphysis (BS)-distance and rotation-angle in relation to the symphysis pubis, revealed almost identical results for the two procedures. The US-measurements had a better accuracy than the CCU measurements. Furthermore, hypermobility of the bladder neck was related to grade of incontinence and to diagnoses including anterior suspension defects. Presence of a cysto- or rectocele affected the size of the rotation angles. Patients with a cystocele had a 16o larger rotation angle by both procedures. Presence of a rectocele increased the rotation angle, measured by US, but decreased the angles, measured by CCU. Furthermore, the ability to withhold was decreased, when the patient had a rectocele. Since the same information of bladder neck suspension is provided by the two methods, and since the US-criteria revealed a better accuracy and a good clinical reliability, Ultrasonography is recommended for evaluation of bladder neck anatomy - also for practical and economical reasons.

Vaginal Ultrasonography versus endometrial biopsy in women with postmenopausal bleeding.
American journal of obstetrics and gynecology, 1997Co-Authors: Anne M. Weber, Jerome L. Belinson, Linda D. Bradley, Marion R. PiedmonteAbstract:Abstract OBJECTIVE: Our goal was to compare the predicted outcomes and costs of two diagnostic algorithms for postmenopausal bleeding. STUDY DESIGN: Two algorithms for postmenopausal bleeding were developed, one with Vaginal Ultrasonography and the other with office endometrial biopsy as the first test. Literature review was performed to estimate the probability of either an abnormal result of Ultrasonography or a nondiagnostic biopsy, or both. Cost and sensitivity analyses were performed. RESULTS: Estimated probability of a nondiagnostic endometrial biopsy was 28%, and estimated probability of an abnormal result of Vaginal Ultrasonography (either inconclusive or endometrial thickness >4 mm) was 55%. Cost analysis showed that Vaginal Ultrasonography as the first diagnostic test cost $230 per patient on average compared with $244 for endometrial biopsy, with savings ranging from $14 to $20 per patient over a wide range of possible values for estimated parameters. CONCLUSION: Vaginal Ultrasonography costs slightly less than office endometrial biopsy as the first test in the diagnostic evaluation of women with postmenopausal bleeding.

ultrasound assessment of ovarian tumors comparison between transVaginal 3d technique and conventional 2 dimensional Vaginal Ultrasonography
Ultraschall in Der Medizin, 2008Co-Authors: G Weber, Eberhard Merz, Franz Bahlmann, D. MacchiellaAbstract:DEFINITION Three-dimensional (3D) ultrasound is capable of visualising all three orthogonal planes simultaneously. With the stored volumetric data, imaging planes can be reconstructed that are not visible when using standard vaginosonographic procedures. AIMS OF THE STUDY In patients with ovarian tumours, diagnosis and the appropriate therapeutic approach depend to a crucial degree upon the results of sonographic investigations, which therefore need very exact diagnostic data. Two-dimensional (2D) vaginosonography can only yield sagittal and frontal sections of the lesser pelvis; 3D volume scanning, however, visualises all three perpendicular planes simultaneously on a monitor screen. In cystic tumours of the ovary, conspicuous parietal structures can be specifically localised and rendered three-dimensionally in the surface mode. Such imaging capabilities create new perspectives in assessing ovarian tumours. METHOD Within the framework of a prospective study at the Gynecological Clinic of the University of Mainz, we compared the sonographic findings obtained for 45 patients with ovarian tumours using 2D and 3D vaginosonography. After the transVaginal application of conventional 2D vaginosonography, the tumours were examined by means of 3D sonography. RESULTS The use of 3D volume scanning was advantageous because we could image specifically targeted planes and reconstruct image planes that cannot be shown using standard vaginosonography. In addition, the volumetric technique allows 3D surface reconstruction of conspicuous parietal structures from a wide variety of different perspectives. These advantages allow one to better assess the grading of tumours especially of those that are cystic. Problems associated with the application of this transVaginal 3D technique module orientation within a given volume, the overlapping of sonographic planes, increase the time required for surface calculations and increased data storage capacity. CONCLUSION TransVaginal 3D sonography represents a new technique of imaging. Owing to its ability to register all three imaging planes simultaneously as well as to visualise surfaces three-dimensionally, this technique opens up new sonomorphologic possibilities in the evaluation of ovarian tumours.
