Urethral Catheterization, Men
Updated: Aug 10, 2008
Introduction
Urethral catheterization is a routine medical procedure that facilitates direct drainage of the urinary bladder.1 It may be used for diagnostic purposes (to help determine the etiology of various genitourinary conditions) or therapeutically (to relieve urinary retention, instill medication, or provide irrigation). Catheters may be inserted as an in-and-out procedure for immediate drainage, left in with a self-retaining device for short-term drainage (eg, during surgery), or left indwelling for long-term drainage for patients with chronic urinary retention. Patients of all ages may require urethral catheterization, but patients who are elderly or chronically ill are more likely to require indwelling catheters, which carry their own independent risks.
The basic principles underlying urethral catheterization are gender-neutral, but the specific aspects important in the technique of male catheterization are described in this article. For a procedural description for female patients, see Urethral Catheterization, Women.
For more information on urinary retention, see the Medscape CME activity Management of Urinary Retention Reviewed.
Indications
- Diagnostic
- Collection of uncontaminated urine specimen
- Monitoring of urine output
- Imaging of the urinary tract
- Therapeutic2
- Acute urinary retention (eg, benign prostatic hypertrophy, blood clots)3
- Chronic obstruction that causes hydronephrosis4
- Initiation of continuous bladder irrigation
- Intermittent decompression for neurogenic bladder
- Hygienic care of bedridden patients
Contraindications
Urethral catheterization is contraindicated in the presence of traumatic injury to the lower urinary tract (eg, urethral tear). This condition may be suspected in male patients with a pelvic or straddle-type injury. Signs that increase suspicion for injury are a high-riding or boggy prostate, perineal hematoma, or blood at the meatus. When any of these findings are present in the setting of concerning trauma, a retrograde urethrogram should be performed to rule out a ureteral tear prior to placing a catheter into the bladder.2
