The Effect of Increasing Intra-abdominal Pressure on the Position of the Bladder Neck in Ultrasound Imaging

Abstract: Zweck, Anlage und Ort der Studie: Position und Beweglichkeit des Blasenhalses sind wichtige Faktoren in der ¾tiologie der echten Stressinkontinenz. Zweck der Studie war die Bewertung der Wirkung verschiedener intraabdominaler Druckwerte (30 cm H 2 O und maximaler intraabdominaler Druck) auf die Position und Mobilität des Blasenhalses und die Bestimmung der dadurch bedingten Veränderungen anderer sonographischer Parameter der ableitenden Harnwege. Angelegt als Prospektivstudie. Ort der Studie: Geburtshilfliche … Show more

“…a rectal balloon catheter. Other methods, such as the use of a spirometer, are likely to lead to suboptimal Valsalva maneuvers; the pressures used in the one study describing the use of such a device35 were clearly insufficient to achieve maximal or even near‐maximal descent36.…”

“…Some investigators measure the retrovesical (RVA or posterior urethrovesical PUV) angle between proximal urethra and trigone ( [27], see Fig. 3), others determine the angle γ between the central axis of the symphysis pubis and a line from the inferior symphyseal margin to the bladder neck [28,29]. Of all those ultrasound parameters of hypermobility, bladder neck descent may have the strongest association with Urodynamic Stress Incontinence (USI) [30].…”

“…It is likely that methodological differences such as patient position, bladder filling and quality of Valsalva manoeuvre (i.e., controlling for confounders such as concomitant levator activation) account for the above discrepancies, with all known confounders tending to reduce descent. Attempts at standardizing Valsalva manoeuvres [38,39] have not found widespread application since this requires intraabdominal pressure measurement, i.e., a rectal balloon catheter. Other methods such as the use of a spirometer are likely to lead to suboptimal Valsalva manouvres; the pressures used in the one study describing the use of such a device [38] were clearly insufficient to achieve maximal or even nearmaximal descent [39].…”
