Foley (Urethral) Catheterization Assess indications. Note that catheter insertion carries a risk of infection.
A specific surgical consent is not generally obtained. Explain urethral catheterization (may be intermittent or indwelling). Indications: Diagnostic To collect uncontaminated urine specimen Study anatomy of the urinary tract Urine output monitoring Therapeutic Acute urinary retention Chronic obstruction causing hydronephrosis Intermittent bladder decompression for neurogenic bladder Chronically bed-ridden patients for hygiene Contraindications: 1. Urethral injury Trauma patients with blood at meatus or abnormal prostate location on rectal exam. Equipment: 1. 2. Catheter tray. Foley Catheter: 18 F Adults 18 F Coud if obstruction at prostrate 5 12 F Children 5 F feeding tube with tape infants < 6 months 3. Drainage bag.
4. Procedure:
Transurethral topical Lidocaine jelly (Uro-jet). [OPTIONAL]
1. Consider prophylactic antibiotics: valvular heart disease or acute prostatitis. 2. Consider intraurethral anesthetic (Uro-jet). 3. Position: supine, frogleg or knees flexed. 4. Locate meatus. (Fig. A) 5. Apply antiseptic. 6. Gently insert lubricated tube until urine is obtained. (Fig. B) 7. Inflate retention balloon slowly with 5cc saline. 8. Connect to drainage system. 9. Secure tube with tape.

Removal:
Deflate retention balloon by aspirating contents with 10cc syringe from side port.
Complications: Prevention and Management
Complication: Inability to locate urethra: Prevention: Proper position. Management: Compress foreskin edema. Use lubricated pediatric vaginal speculum with edematous foreskin. Discard catheter. Re-attempt with fresh catheter. Urology consult. Trial of smaller tube. Coud Catheter. Aseptic technique. Change catheter
Vaginal catheterization Paraphimosis: Urethral stricture: Enlarged prostrate: UTI:
Position. Properly replace foreskin.
Minimize time Foley remains antibiotics in. Prophylactic abx as indicated Inability to deflate: Remove syringe adaptor. Insert guidewire into inflating channel balloon water should flow out. Withdraw catheter gently, taking care not to splash from tip.
Documentation: Note indications. Describe technique, size / type of catheter and amount of fluid injected into retention balloon. Note complications, if any, and management.
General Items for Evaluation: Understands indications/contraindications Educates/prepares patient Identifies proper landmarks Uses sterile techniques Performs procedure correctly Understands potential complications and their management Adequate documentation performed
