Nurses are key professionals in the prevention of complications associated with indwelling urinary catheterization in the hospital setting. In this context, bladder training through catheter clamping is an important nursing practice. Indwelling catheter clamping in bladder training was first proposed by Ross in 1936. There is no clear information and sufficient evidence for catheter clamping in bladder training before urinary catheter removal in national and international guidelines for clinical practice.
