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

Regarding short-term catheterization:

  • Antiseptic impregnated catheters reduce urinary tract infections according to a systematic review by the Cochrane Collaboration.[2]
  • "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.[3]
  • Suprapubic catheters "have advantages over indwelling catheters in respect of bacteriuria, recatheterisation and discomfort."[4]

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.[5]
  • It is not clear what methods of intermittent catheterization are best according to at systematic review by the Cochrane Collaboration.[6]

Removal of urinary catheters

For more information, see: urinary retention.

From the patient care standpoint, if the patient has had an indwelling catheter for a significant period of time, bladder retraining may be advisable before removal. This consists of tow 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. [7]

A policy of using of 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."[4]

Retained volumes of more than 900 ml reduced chance of successful removal of the catheter.[8]

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.[9]

Removing the catheter at midnight might be the most effective determinant according to a systematic review by the Cochrane Collaboration.[9]

Alfuzosin 10 mg per day may help[10][11][12] whereas alfuzosin SR 5mg once daily did not help.[13] Tamsulosin, though less well studied, might have less effect on blood pressure.[14]

Intermittent clamping of catheters is of uncertain benefit.[15]
