Title: Urinary Retention Rates After Immediate Removal of Foley Catheter Versus Backfill Void Trial Following Total Laparoscopic Hysterectomy: A Randomized Controlled Trial
Brief Summary: Acute urinary retention is a complication of hysterectomies that can result in bladder over-distension and long term bladder dysfunction. The incidence of acute urinary retention after total laparoscopic hysterectomy (TLH) has been reported to be anywhere between 4% and 34%. Studies have varied in the method of post-operative bladder challenge and the modality of hysterectomy included. Moreover, most of the published studies are retrospective chart reviews or prospective observational studies, with a lack of randomized controlled trials. Risk factors for urinary retention include type of anesthesia used, how the hysterectomy is performed, use of post-operative narcotics, pre-operative urinary retention, and possibly aggressive bladder dissection. With the increased trend towards same-day discharge following TLH, urinary retention may cause unnecessary patient distress and a worsened post-operative course. Standardization of post-hysterectomy bladder challenge and identification of risk factors for urinary retention may aid in preventing urinary retention or acute bladder dysfunction. The primary objective is to compare the rate of void trial failure after TLH with the backfill technique versus the autofill technique.
