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

For more information, see: Urinary tract infection.

Preventing cross infection (nosocomial infection) of the urinary tract is a national priority in the United States.[2][3] Regarding short-term catheterization:

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.[8]
  • It is not clear what methods of intermittent catheterization are best according to at systematic review by the Cochrane Collaboration.[9]

Removal of urinary catheters

For more information, see: urinary retention.

Retained volumes of more than 900 ml reduced chance of successful removal of the catheter.[10] One protocol only inserts a urinary catherter for post-operative retention if the bladder is estimated to contain 500 ml or more of urine estimated by bladder scanning.[11]

Selected randomized controlled trials of adrenergic alpha-antagonists prior to removal of a catheter for acute urinary retention in men.[12][13][14]
Trial Adrenergic alpha-antagonist Result
Lucas[12]
2002		 Tamsulosin 0.4 mg once daily for ≤ 8 days Benefit
Alfaur study[13]
2005		 Alfuzosin 10 mg once daily for 3 days Benefit
Tibung (unpublished)
2006		 Alfuzosin 10 mg once daily for 2 days Insignificant benefit
Shah[14]
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 removal of catheter) according to a systematic review by the Cochrane Collaboration.[15] This review found four trials of alfuzosin (10 mg once daily or 5 mg twice daily)[13] and one of tamsulosin (0.4 mg once daily)[12]. 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.[16]

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."[7]

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.[16]

Intermittent clamping of catheters is of uncertain benefit.[17] 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. [18]
