Urinary Collection Techniques

A clean catch sample is the preferred technique for urine collection, however this may be very time consuming in young children [1].

One way of achieving this in the ED for a child in nappies is to remove the nappy, place several inco-pads over the parent’s lap. Clean the perineum with water. The parent waits with the child on their lap, or on the bed, holding a sterile pot / bowl for the child to pass urine

Using gauze soaked with cold water to rub the suprapubic area has been shown to increase the rate of voiding and clean catch urine collection. [5]

Failing this, urine collection pads may be used. Do not use gauze, cotton wool or other ad hoc techniques, as this greatly increases the risk of contamination.

When not possible or practical to use non-invasive methods, a catheter sample or suprapubic aspiration can be used. Prior to aspiration, ultrasound should be used to demonstrate urine in the bladder. [1]
