Flow diagram of a novel intervention. Note: 1. Record the urine volume and reason for urethral catheter insertion. 2. Apply intermittent catheterization (IC) Q12H when the first-time postvoid residual volume (PVR) is 100–200 ml; IC Q8H, when the PVR is 200–300 ml; and IC Q6H, when the PVR is > 300 ml. Successful removal of the catheter is defined as PVR ≤ 100 ml or a ratio of the actual void volume to the postvoid residual volume of > 2:1
