Urinary Retention After Total Laparoscopic Hysterectomy With Immediate Foley Catheter Removal Versus Backfill Void Trial

A void trial is a test to ensure that a subject does not have urinary retention after a surgical procedure. In an autofill void trial, the subject is allowed to void after surgery and the amount of resulting urine and the amount of urine still remaining in the bladder are measured. In a backfill void trial, water is instilled into the bladder, the foley is removed, and the subject is then allowed to urinate. Again, the amount of urine resulting and the amount of urine still in the bladder are measured.
