Urinary catheterization
In medicine, urinary catheterization is "employment or passage of a catheter into the urinary bladder (urethral catheterization) or kidney (ureteral catheterization) for therapeutic or diagnostic purposes.[1]
Complications
Urinary tract infection
Preventing cross infection (nosocomial infection) of the urinary tract is a national priority in the United States. Regarding short-term catheterization:
- Antiseptic impregnated catheters reduce urinary tract infections according to a systematic review by the Cochrane Collaboration.[2]
- Systemic antibiotics may reduce symptomatic urinary tract infection in women after abdominal surgery.[3]
- "the use of condom catheters is less likely to lead to bacteriuria, symptomatic UTI, or death than the use of indwelling catheters. This protection is especially apparent in men without dementia" according to a randomized controlled trial.[4]
- Suprapubic catheters "have advantages over indwelling catheters in respect of bacteriuria, recatheterisation and discomfort."[5]
Regarding long-term catheterization and prevention of urinary tract infections:
- It is not clear what type of catheterization is best according to at systematic review by the Cochrane Collaboration.[6]
- It is not clear what methods of intermittent catheterization are best according to at systematic review by the Cochrane Collaboration.[7]
Removal of urinary catheters
Retained volumes of more than 900 ml reduced chance of successful removal of the catheter.[8]
| Trial | Adrenergic alpha-antagonist | Result |
|---|---|---|
| Lucas[9] 2002 |
Tamsulosin 0.4 mg once daily for ≤ 8 days | Benefit |
| Alfaur study[10] 2005 |
Alfuzosin 10 mg once daily for 3 days | Benefit |
| Tibung (unpublished) 2006 |
Alfuzosin 10 mg once daily for 2 days | Insignificant benefit |
| Shah[11] 2005 |
Alfuzosin 5 mg twice daily for 36 hours and then again for 2 weeks (Alfuzosin half life is 10 hours) |
No benefit |
Adrenergic alpha-antagonists might be effective (residual volume of <200 ml after removeal of catheter) according to a systematic review by the Cochrane Collaboration.[12] This review found four trials of alfuzosin (10 mg once daily or 5 mg twice daily)[10] and one of tamsulosin (0.4 mg once daily)[9]. The adrenergic alpha-antagonists were started 24 to 72 hours before trial without a catheter (TWOC) in 4 trials and 8 days prior in one trial.
Removing the catheter at midnight might be the most effective determinant according to a systematic review by the Cochrane Collaboration.[13]
Using intermittent catheterisation for postoperative patients was "associated with a lower risk of bacteriuria than indwelling urethral catheterisation, but might be more costly...limits catheterisation to those people who definitely need it."[5]
Regarding how long to wait until a voiding without catheter trial, "a tendency for later removal to be associated with fewer short-term voiding problems, but increasing risk of urinary tract infection, more dissatisfaction and longer hospital stay" according to a systematic review by the Cochrane Collaboration.[13]
Intermittent clamping of catheters is of uncertain benefit.[14] This consists of two cycles of clamping the tube for two hours and releasing it for five minutes, to help restore bladder muscle tone. Since the act of removal often stimulates a strong urge to void, the patient should be given a bedpan or urinal before starting to remove the catheter. [15]
