Catheter valves: are they useful in supporting patients in a trial without catheter?

Abstract

A trial without catheter (TWOC) is a common urological procedure undertaken to remove an indwelling urinary catheter when no longer clinically indicated. An appropriately trained practitioner should undertake a TWOC in a controlled environment to ensure that a further urinary retention does not occur. Indwelling urinary catheters are commonly used with a free drainage system such as a leg bag, which continually empties the bladder. This article examines the potential benefits of using a catheter valve as an alternative to free drainage, prior to undertaking a TWOC, to optimise clinical outcomes and patient experience. This article will guide nurses to increase their knowledge of catheter valves to promote person-centred informed decision-making.
