Urinary Retention After Vaginal Delivery With Epidural Anesthesia.

Study Overview
=================
Brief Summary
-----------------
The investigators intend to compare the rate of urinary retention among female patients after vaginal delivery under epidural anesthesia, depending on bladder catheterization type, either by a foley catheter inserted adjacent to epidural anesthesia or intermittent catheterization applied every 4 hours during labor.

Detailed Description
-----------------
An explanation about the study will be delivered to each participant and each participant will sign a confirmed consent. Patients will be randomized between 2 groups of treatment: 1. intermittent catheterization applied every 4 hours during labor. 2. foley catheter inserted adjacent to epidural anesthesia. In patients with a foley catheter, the catheter will be removed soon after delivery. Participants will be followed by a clinician post labor. An abdominal US will be performed either 4 hours after delivery or after the participant urinates to check the bladder volume. Patient information including demographic information, information regarding the patient's pregnancy and delivery will be collected from the patient's electronic record.
