The effects of a catheter clamping protocol on bladder function in neurosurgical patients: a controlled trial.

There is scant evidence-based literature on the best strategies for short-term urinary catheter removal. This clinical trial explored the effects of an early urinary catheter clamping protocol on bladder function in neurosurgical patients. Eligible patients were divided into observation and control groups. Those in the observation group had their catheter clamped postoperatively on return to the ward and unclamped at dedicated intervals. The control group received standard care; the catheter was on free drainage during the entire time in situ. The mean catheter indwelling time was 2.6 days. Compared with the control group, the observation group experienced shorter time to first postoperative urination, less residual urine volume and better subjective perception during their first postoperative urination. For patients undergoing neurosurgery and associated short-term indwelling urinary catheterization, an early catheter clamping protocol is effective in facilitating bladder function, reducing the rate of dysuria and making patients feel more comfortable after catheter removal.
