Urinary catheterisation: assessing the best options for patients.

There are two methods of draining urine from the bladder via a catheter. They involve intermittent catheterisation or the use of an indwelling catheter. This article outlines the history of urinary catheterisation, reasons for its use, and the rationale for choosing the most appropriate option for patients with urinary dysfunction. Many articles have been written on urinary catheterisation, reasons for insertion and probable catheter-associated problems. In deciding which method of catheterisation is required, whenever possible the needs and views of the patient should be discussed before a decision is taken.
