Prediction of urinary retention after surgery for rectal cancer using voiding efficiency in the 24h following Foley catheter removal

摘要

Purpose Postoperative urinary retention is a common adverse effect after rectal surgery. Current methods for assessing postoperative urinary retention (residual urine volume) are inaccurate and unable to predict long-term retention. Voiding efficiency is an effective indicator of postoperative urinary retention in urological and gynaecological fields, but not in colorectal surgery. We aimed to determine whether voiding efficiency in the initial 24h after urinary catheter removal was more effective in predicting the incidence of postoperative urinary retention than residual urine volume.
