Intermittent catheterisation (IC) has a lower risk of infection compared with indwelling catheterisation, and so should be considered in preference to an indwelling catheter. Intermittent catheters are typically single-use urinary catheters. That is, you use it to urinate once then you dispose of it. (Nursingtimes 1935).
Using an intermittent catheter may be referred to as self-catheterization, because you insert the catheter into the bladder yourself by threading it through the urethra (Nursingtimes 1935). With a regular intermittent catheter, you urinate in the toilet rather than into a collection bag. Since intermittent catheters do not remain in the body, you are less likely to develop urinary tract infections. Indwelling catheters are for long-term use to manage bladder problems such as urinary incontinence or urinary retention (Nursingtimes 1935). One important thing to note about catheters is some require a doctor for insertion, as is the case with this variety. There are two types of indwelling catheters: Foley catheters and suprapubic catheters. (Nursingtimes 1935).
