A randomised controlled trial evaluating the efficacy of an open-ended urinary catheter for catheter-related bladder discomfort

Basic Information

Recruitment status Recruiting
Health condition(s) or Problem(s) studiedNon muscle invasive bladder cancer, renal cell carcinoma, upper truct urothelial carcinoma
Date of first enrollment16/08/2024
Target sample size100
Countries of recruitment
Study typeInterventional
Intervention(s)The following research and control instruments will be used in this study. The following study instruments and control instruments will be used in this study: - OEFC and FC: 18Fr. 3-way. Transurethral resection of bladder tumours: 18Fr. 3-way Other techniques (total nephroureterectomy, nephrectomy, partial nephrectomy): 14Fr. 2-way (14Fr does not have a 3-way) FC: Round tip Foley catheter OEFC: Short tip tip opening Foley catheter In both cases, the tip of the catheter can be easily implanted (fixed) in the bladder by inflating the balloon after insertion, and urine in the bladder is continuously guided (discharged) out of the body through the lumen of this product by implantation. The product can be easily removed (replaced) by deflating the balloon in the bladder (aspirating balloon inflation water from the valve).

Outcome(s)

Primary OutcomePercentage of CRBDs at 6 hours post-operatively
Secondary Outcome1) Percentage and severity* of CRBD at defined time points (0: no CRBD, 1: mild, 2: moderate, 3: severe). 2) Urethral pain scale* (Wong-Baker face scale) at defined time points 3) Type of drug therapy for CRBD, number of times used 4) Percentage of adverse events The defined time points are 0, 1, 3 and 6 hours postoperatively, plus 24, 48 and 72 hours during catheterisation after 6 hours and up to 72 hours after removal of the catheter during catheterisation. Catheters were left in place for a minimum of 6 hours and removed at any time thereafter.
