This will be a descriptive study measuring the post—void residual of patients in the third trimester and postpartum. Also, bladder scan values will be compared to the amount of urine obtained from a Foley catheter to determine the accuracy of the bladder scanner in the third trimester and postpartum.

Further study details as provided by West Virginia University:

Primary Outcome Measures:
  • Define normal post-void residual volume in third trimester pregnancy and post-partum. [ Time Frame: 12-24 hours ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Calculate the validity of measurements form the bladder scanner ultrasound for bladder volumes during the third trimester of pregnancy and post-partum. [ Time Frame: 12-24 hours ] [ Designated as safety issue: No ]

Enrollment: 35
Study Start Date: October 2008
Primary Completion Date: December 2009 (Final data collection date for primary outcome measure)
