Intermittent self-catheterisation (ISC) is not a new concept. However, it is a method that could be more widely used by patients to drain the bladder rather than having an indwelling catheter with a drainage bag and its associated problems. The author describes the procedure, patient assessment, and the training required by patients so that they can undertake ISC. Self-catheterisation promotes patient independence, improves quality of life and helps to avoid complications associated with indwelling urinary catheters.
