P26.16: Reliability of three-dimensional ultrasound fetal urinary bladder volume measurement

Is portable three-dimensional ultrasound a valid technique for measurement of postpartum urinary bladder volume?

OBJECTIVE To determine the accuracy of bladder volume (BV) measurement and to identify factors that influenced the ultrasound bladder scanner (UBS) measurement of BV in postpartum women compared with transurethral catheterization. MATERIALS, METHODS AND RESULTS A total of 190 paired measurements were performed on 190 women aged between 16 and 47 years. Majority of the women (36.9%) were in th...

Three-dimensional Ultrasound in the Assessment of Fetal Limb Volume*

Measurement of fetal nuchal translucency thickness by three-dimensional ultrasound.

OBJECTIVE To investigate the feasibility and repeatability of nuchal translucency thickness measurement using three-dimensional ultrasound. METHODS Forty consecutive women with uncomplicated singleton pregnancies attending for Down syndrome screening at 11-14 weeks' gestation were included in this prospective crossover trial. Nuchal translucency thickness was measured using both two-dimension...

Use of bladder volume measurement assessed with ultrasound to predict postoperative urinary retention

OBJECTIVE Postoperative urinary retention (POUR) is a common complication after spinal anesthesia. Ultrasound (US) is a simple, non-invasive method to estimate bladder volume before and after surgery. Primary aim of the present study was to investigate utility of bladder volume measured before and after surgery in prediction of POUR risk. Secondary aim was to investigate necessity of urethral c...

Fetal Heart Assessment Using Three-dimensional Ultrasound

Cardiac anatomy is complex and often difficult to visualize or comprehend. 3D echocardiography is an area undergoing rapid development that represents a natural extension of conventional sonography methods which require integrating a series of 2D image slices to develop a 3D impression of underlying anatomy or pathology. This paper will review some of the basic concepts behind three-dimensional...
