2021-03-05 12:00 AM

This procedure is used for bladder decompression, e.g. potential obstruction, accurate measurement of urine output, and collection of urine for bacteriological investigation in suspected urinary tract infection.

Indications

This procedure is used for bladder decompression, e.g. potential obstruction, accurate measurement of urine output, and collection of urine for bacteriological investigation in suspected urinary tract infection.

Equipment

  • 3–8Fr urinary catheter (depending on child’s size).
  • Anaesthetic lubricating gel, e.g. 0.1% lidocaine gel.
  • Water-based antiseptic solution, e.g. 0.5% chlorhexidine.
  • Sterile urine sample container.
  • Sterile gloves and adhesive tape.

Procedure

  • Lay child in supine position with hips abducted, with an assistant holding the child.
  • Clean penile tip or vulval area with an antiseptic solution.
  • Apply anesthetic lubricating gel to catheter tip and urethral opening.
  • Partially withdraw foreskin in males. Part the labia in females.
  • Insert and advance the catheter into the urethra in a posterior manner until urine is obtained, indicating that the bladder has been entered.
  • Once in the bladder, inflate the catheter balloon with saline if the catheter is intended to be indwelling.
  • Use adhesive tape to secure the catheter to the thigh.
  • Connect catheter to the urine collection bag or aspirate urine for analysis.
