Further study details as provided by Mayo Clinic:

Primary Outcome Measures:
  • Need for insertion of catheter after Foley removed. [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 5 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Development of urinary tract infection [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 5 weeks ] [ Designated as safety issue: No ]

Estimated Enrollment: 242
Study Start Date: December 2011
Estimated Study Completion Date: December 2014
Estimated Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Early (within 48 hours of surgery)
Patients will have their urinary catheter removed within 48 hours of surgery
Late (6 hours after epidural removal)
Patients will have their urinary catheter removed 6 hours after their epidural is removed

Detailed Description:

We hypothesis that removing the foley catheter within 48 hours after a thoracotomy in patients that have an epidural catheter will result in an increase in the rate of urinary infections and the need for reinsertion of the foley. We have designed a randomized trial to test this hypothesis.

Study Population

Patients undergoing thoracic surgery at the Mayo Clinic


Inclusion Criteria:

  • epidural catheter after thoracic surgery
  • foley in place

Exclusion Criteria:

  • < 18 years of age
  • death in hospital within 30 days of the operation
  • length of hospital stay is less than 48 hours
  • epidural catheter is removed before the 3rd postoperative day
  • patients who have a suprapubic catheter or no bladder
  • patients who require a urologist or a urologic technician to insert the Foley catheter at the time of surgery
  • patients who were being intermittently catheterized before surgery
  • patients with a known urinary tract infection preoperatively
  • patients required to keep Foley in since they required close monitoring of urinary output
