Title: Optimal Timing of Foley Catheter Removal in Patients Undergoing Thoracic Surgery With Epidural Analgesia: A Randomized, Controlled Trial
Brief Summary: Is the early removal of Foley catheter safe in patients undergoing general thoracic surgery with an epidural catheter in place?

* patients required to keep Foley in since they required close monitoring of urinary output
B: Inclusion Criteria:

* Sacrocolpopexy with or without concomitant procedures
* Patients having the first start surgery of the day to standardize hospital time.

Exclusion Criteria:

* Elevated post void residual (PVR)

Exclusion Criteria:

* same day surgery
* non-ambulatory (allowed to use an assistive device)
* inability to provide informed consent, age \< 21 years
* pregnancy or desire for future pregnancy
* systematic disease known to affect bladder function (Parkinson's disease, Multiple Sclerosis, Spina Bifida, spinal cord injury or trauma and neurogenic bladder)
* known preoperative urinary retention (defined as a post-void residual \> 100mL)
* an untreated urinary tract infection at the time of surgery
* treatment at the time of surgery for urinary tract infection
