Die Messung des infrapubischen Winkels in der 3-D-Perineal-Sonografie und seine Beziehung zu geburtshilflichen Parametern

2012

Ziel: Die 3-D-Sonografie bietet einige Vorteile gegenuber der 2-D-Sonografie in der Urogynakologie. Neben den Weichteil-Strukturen ermoglicht die Darstellung der axialen Ebene die Identifikation des Levators und der Symphyse. Ziel dieser Arbeit war es, eine genaue Messung des infrapubischen Winkels sowie des Symphysenspalts durch Rotations-Anpassung zu beschreiben und die Inter-Observer-Variabilitat zu bestimmen. Zusatzlich wurden die Korrelationen des infrapubischen Winkels mit dem Auftreten von Levator-Defekten und der Dauer der Austreibungsperiode untersucht. Material und Methoden: Am 2. bis 3. Tag postpartal nach Vaginalgeburt wurde eine 3-D-Sonografie durchgefuhrt. Die Auswertung erfol…

Zur Wirkung gepulster elektromagnetischer Felder geringer Leistungen auf Gedächtnisprozesse

2004

Zusammenfassung In einer Pilotstudie sollte die Wirkung elektromagnetischer Felder auf den Organismus untersucht werden. Mittels eines psychophysiologischen Tests wurde die Veranderung der Gedachtnisleistungen unter den Bedingungen mit und ohne Belastung durch gepulste Felder (GMS-Standard) an 33 Probanden uberpruft. Zur Objektivierung der kognitiven Leistungen fand das psychophysiologische Verfahren zur Bewertung der “Ordnungsschwelle” (OS) Verwendung. Die Untersuchung erfolgte in einem akustisch abgeschirmten Raum, in dem die Versuchsteilnehmer sich auf einer Liege entspannen sollten. Wahrend dieser Relaxationsphase (30 Min.) fand die Feldexposition statt. Durch Messungen vor und nach die…

P20Early membrane funnelling may occur from 16 weeks onwards and carries a worse prognosis

2000

Background Sonographic screening for cervical incompetence during pregnancy is currently a routine procedure. However, no consensus exists on the optimal gestational age to perform such screening. Method Serial transvaginal ultrasound examinations of the uterine cervix were routinely performed from 12 weeks onwards. The screening was considered positive when membrane funnelling was present or the cervical length was < 2 cm. Therapeutic measures included bed rest, antibiotics, tocolytic treatment and a modified McDonald's cervical suture (up to 25 weeks). Results Membrane funnelling was detected between 16 and 22 weeks (group A) in 9 women (31%); between 23 and 28 weeks (group B) in 11 women…

Measurement of subpubic arch angle by three-dimensional transperineal ultrasound and impact on vaginal delivery

2015

Objectives To assess whether antepartum measurement of the subpubic arch angle (SPAA) as a parameter of the bony pelvic outlet can predict vaginal delivery. Methods Between January 2007 and June 2011, 625 nulliparous women with a singleton pregnancy were recruited from the antenatal clinic to be interviewed and have a four-dimensional transperineal ultrasound examination. Ultrasound examinations were performed between 34 and 36 weeks of gestation. Volume ultrasound data were saved for offline analysis, blinded against all other data. The SPAA was measured in the axial plane and logistic regression analysis was used to examine the association between SPAA and outcomes of vaginal delivery vs …

Prevalence of Levator Ani Defects in Urogynecological Patients

2016

Introduction: Defects of the levator ani muscle complex could represent a pathophysiological link between vaginal birth trauma and urogynecological symptoms many years later. The aim of our study was to determine the prevalence of levator ani muscle defects using 3D or 4D ultrasound and palpation in urogynecological patients. Material and Methods: Urogynecological patients were retrospectively investigated using 3D or 4D ultrasound. Clinical examination consisted of palpation and 3D or 4D imaging of the levator ani muscle. Results: A total of 319 women were included in the analysis. Mean age was 64.9 years, average parity was 2.1. Stress incontinence was present in 50.8 %, overactive bladde…

Sonographic size of uterus and ovaries in pre- and postmenopausal women

1996

Uterine and ovarian size were measured in 765 pre- and postmenopausal women by transvaginal ultrasound. Of these, 263 (premenopausal, n = 155; postmenopausal, n = 108) were found to have neither uterine nor ovarian pathological findings. According to parity, premenopausal women were separated into three groups: nullipara, primipara and multipara. Postmenopausal women were separated into two groups according to years since menopause: 5 years since menopause. In the premenopausal group, a parity-related enlargement in uterine size was observed between nulliparous and parous women. After the menopause, a significant reduction in uterine size and in the corpus-cervix ratio was observed. The red…

F117Hystero-embryoscopic findings in early nonviable pregnancies

2000

Background A high proportion of early pregnancy losses are associated to abnormal embryo development. However, chromosomal analysis of routine curettage samples are of limited value; and histopathological examinations of the embryos are rarely performed in clinical practice. Method A transcervical hystero-embryoscopy was performed prior to the curettage in 31 nonviable first-trimester pregnancies and a control group of 5 early terminations of pregnancy. In the study group, the estimated gestational age according to the ultrasound findings was 6.7 (4–9) menstrual weeks. Direct biopsies of different gestational structures were taken during the endoscopic procedure. Results In nonviable pregna…
