• We prospectively assessed the ability of a novel transurethral catheterization safety valve to prevent urethral catheter balloon injury in a multi-institutional clinical setting. A prospective, multi-institution study was conducted. The safety valve was introduced for urinary catheterization in 6 hospital groups (4 in Ireland; 2 in the UK). The safety valve allows fluid in the catheter system to vent through a pressure relief valve if attempted intraurethral inflation of the catheter's anchoring balloon occurs. Device usage was studied over a 12-month period, with data recorded using a 7-item data sticker containing a scannable QR code. "Venting" through the safety valve during catheterization was indicative of prevention of a urethral injury. An embedded 3-month study was conducted in 3 centers, with any catheter balloon injuries occurring during catheterization without safety valve use referred to the on-call urology team recorded. Health economic analyses were also performed. During the overall 12-month device study phase, 994 urethral catheterizations were performed across study sites. Twenty-two (2.2%) episodes of safety valve venting were recorded. No urethral injuries occurred in these patients. In the embedded 3-month study, 18 catheter balloon injuries were recorded in association with catheterizations performed without the safety valve. Based on confirmed and device-prevented urethral injuries, the injury rate for urethral catheterization without safety valve use was calculated to be 5.5/1,000 catheterizations. The safety valve has the potential to eliminate catheter balloon injury if widely adopted. It represents a simple, effective, and innovative solution to this recurring problem applicable to all patient cohorts.
