How long do you clamp a catheter?

The study will be conducted at University Hospital Alcorcón Foundation, belonging to the public network of hospitals of Madrid Health Service.

The aim of this study is to evaluate the effects of clamping the urethral catheter prior to removal and determine which of the two options (clamping or free drainage) is the most recommended for removal of bladder catheterization in adults.

The interest of this study is given by the importance of proper handling of catheterization in the health of patients admitted to a hospital and are subjected to this technique. Increase its interest the need for implementation of evidence-based care, and limited scientific literature on the subject.

The study population will be patients undergoing short-term urethral catheterization at the Internal Medicine Service in the University Hospital Alcorcón Foundation.

The methodology of the study is experimental, randomized clinical trial without drug type. Interventions (prior clamped and free drainage) will be assigned in a randomized manner.

Interventions and data collection of patients who met the inclusion criteria to join the study will be conducted during 2016 and the first quarter of 2017. It is planned to present results at the end of 2017.

Arm	Intervention/treatment
Experimental: Clamping group Indwelling urinary catheter is clamped before removal and unclamped when the patient expresses his desire to urinate.	Procedure: Clamping To clamp before the removal of short-term indwelling urethral catheters
No Intervention: Free drainage group The urinary catheter will be removed without prior clamping.

Aims and objectives: To determine the effect of clamping the indwelling urinary catheter before its removal on bladder reconditioning in patients with cervical cancer after radical hysterectomy.

Background: It is suggested that indwelling urinary catheters should be clamped intermittently to fill the bladder and restore bladder function before removal. However, indwelling urinary catheter clamping showed no effect on bladder reconditioning according to some clinical studies.

Design: Randomised controlled study.

Methods: A total of 210 patients with cervical cancer after type C radical hysterectomy were randomised on 1:2 into two groups. In the clamping group, indwelling urinary catheters were clamped intermittently for 48 hours before removal based on a bladder-training sheet, while in the control group, the indwelling urinary catheters were removed without clamping. The primary outcome of the study was the rate of recatheterisation. The secondary outcomes included residual urine volume 24 hours after removal, incidence of urinary tract infection and duration of recatheterisation.

Results: Seventy patients were assigned to the clamping group and 128 to the control group with paralleled baseline characteristics. The days of the primary catheterisation (13·20 ± 0·79 vs. 13·38 ± 1·04) and the incidence of urinary tract infection (22·9% vs. 20·3%) had no significant differences between the two groups. Ten patients in the clamping group and 19 in the control group underwent recatheterisation, the incidence of which showed no significant difference (14·3% vs. 14·8%). The days of recatheterisation were not statistically different between the two groups (11·40 ± 6·75 vs. 9·42 ± 5·23). However, the residual urine volume 24 hours after removal was higher in the clamping group than that in the control group.

Conclusions: Bladder recondition through indwelling urinary catheter clamping may not restore bladder function in patients after radical hysterectomy.

Relevance to clinical practice: As indwelling urinary catheter clamping may increase the residual urine volume after indwelling urinary catheter removal and lead to an increased nursing workload, it should not be recommended in patients with cervical cancer postoperatively.
