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...
متن کاملUltrasound-Guided Needle Technique Accuracy
BACKGROUND AND OBJECTIVES Ultrasound-guided regional anesthesia facilitates an approach to sensitive targets such as nerve clusters without contact or inadvertent puncture. We compared accuracy of needle placement with a novel passive magnetic ultrasound needle guidance technology (NGT) versus conventional ultrasound (CU) with echogenic needles. METHODS Sixteen anesthesiologists and 19 reside...
متن کاملUrinary bladder cancer: diffusion-weighted MR imaging--accuracy for diagnosing T stage and estimating histologic grade.
PURPOSE To prospectively evaluate the ability of diffusion-weighted (DW) magnetic resonance (MR) imaging to be used to determine the T stage of bladder cancer and to measure the correlation between the apparent diffusion coefficient (ADC) and histologic grade. MATERIALS AND METHODS This study was approved by the local institutional review board. All patients gave written informed consent. For...
متن کاملUse 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...
متن کاملAccuracy of ultrasound estimates of urine volume.
Ultrascan and actual catheterization volumes were compared on 48 urology, general surgery, and rehabilitation patients. The findings suggest that mean scan and actual urine volumes can be considered equal. In clinical situations where it is necessary to determine residual urine volume, the bladder scan technology is a good alternative to an invasive catheterization procedure.
