Suprapubic aspiration of urine

 

Optimal method for obtaining urine for bacteriology in a child <2yr old.

 

Equipment

 

21–23G needle.

 

2–5mL syringe.

 

An alcohol impregnated swab.

 

Sterile urine sample container.

 

Cotton wool or gauze swab and adhesive plaster.

 

Procedure

 

Wait at least 30min from last urination.

If in doubt as to whether the bladder contains adequate urine, perform bladder US to confirm.

Place child supine (with an assistant holding hips abducted) and then identify site—midline anterior lower abdominal wall 1cm above the pubic bone.

Clean site with an alcohol impregnated swab.

Insert needle connected to the syringe at 90° to the skin, aspirating  continuously until urine is obtained.

   Insert to almost the depth of the needle. If no urine is obtained, partially withdraw it before inserting again at different angle.

Once required urine is aspirated, remove the needle, press on puncture site with cotton wool or gauze swab, and then apply an adhesive plaster.

Place urine in sterile container.

If unsuccessful, repeat the procedure 30–60min later.
