Catheters: design, selection and management

Urinary catheterization is a common procedure that is performed on 12% of hospital patients (Crow et al, 1996) and 4% of community patients (Getliffe, 1990). When considering catheterization as a method of care, many decisions need to be made in order to select the optimum equipment and provide effective catheter care. This includes selecting the type of catheterization that needs to be performed, i.e. intermittent or indwelling, and choosing the right catheter material, size and balloon infill volume. The type and design features of the urinary drainage and suspensory system have a direct effect on individual patient comfort, dignity and life. Aspects of catheter care that need to be considered include: meatal hygiene, fluid intake, bladder washouts, constipation, clamping catheters, collecting specimens of urine, fixation of catheters and sexuality.
