Bladder Drainage During Labor: A Randomized Controlled Study of Obstetric Foley Therapy (SOFT)

This study has been completed.
Information provided by (Responsible Party):
Loyola University Identifier:
First received: August 14, 2009
Last updated: May 17, 2017
Last verified: May 2017
The goal of this study is to compare two clinically-relevant bladder drainage techniques. This is a randomized controlled trial with a single primary outcome of time to delivery. The results will inform clinical decisions about method of catheterization during labor.

Condition Intervention
Labor Procedure: Indwelling catheter Procedure: Intermittent straight catheterization

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Study of Obstetric Foley Therapy (SOFT Trial)

Further study details as provided by Loyola University:

Primary Outcome Measures:
  • Time to Delivery (by Any Route) [ Time Frame: 1 day ]
    Time to delivery defined as IV placement to delivery of infant.

Secondary Outcome Measures:
  • Difference in Cost Between the Two Interventions [ Time Frame: End of study. ]
    Cost of the intermittent vs. foley catheterization procedures was measured and reported in mean dollars.

Enrollment: 139
Study Start Date: July 2009
Study Completion Date: December 2009
Primary Completion Date: December 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Indwelling foley catheter
Insertion of an indwelling foley catheter when bladder emptying is necessary. The indwelling catheter will remain in place until the time of delivery.
Procedure: Indwelling catheter
Indwelling bladder catheter will remain in place until time of delivery.
Active Comparator: Intermittent straight catheterization
Intermittent straight catheterization will be performed as needed during labor.
Procedure: Intermittent straight catheterization
intermittent straight catheterization will be performed on an as needed basis until time of delivery.

Detailed Description:

Urinary catheterization is a common practice during labor following placement of an epidural for pain control, as this form of anesthesia is known to inhibit normal bladder emptying. There is insufficient evidence to guide clinicians in selection of an indwelling catheter versus intermittent straight catheterization during the course of labor.

The goal of this randomized control trial is to compare two clinically-relevant bladder drainage techniques.
