Chapter 5 68 underrated. Randomized controlled trials on the bladder scan protocol are needed to confirm the presented results and should focus on cutoff value’s at different steps in the bladder scan protocol. Furthermore, selection criteria are needed to detect high-risk patients. To ensure patient’s safety, these patients should be treated with indwelling catheterization prior to surgery. When using a nurse-led bladder scan protocol, this study showed a low incidence of POUR after fast-track hip and knee arthroplasty in comparison with recent literature.
