Nothing slows down the ED flow like waiting for the urine flow of an infant or toddler. Whether or not to screen for UTI with a clean catch urine vs obtain a catheterized specimen will be left for another discussion, but here are some of the latest techniques described for obtaining clean catch specimens. (For all, clean genital area thoroughly first)

“CCU” procedure, first described by Herreros Fernandez et al, Arch Dis Child 2013;98:27, 80 infants aged < 30 days.

Patient held under armpits with legs dangling in upright position. Suprapubic area gently tapped at 100 taps/minute x 30 seconds, followed by light circular massage of the lower back x 30 seconds. Repeat these maneuvers until urine collected. Successful in 86% of the infants with median time to collection 45 seconds.

Labrosse et al, Pediatrics 2016;138(3):320160573 studied this CCU method with the addition of another person flexing the hips of female children, 126 infants < 6 months old. CCU method successful in providing urine sample within 300 seconds in 49%, median time 45 seconds. More successful in < 3 months old than 3-6 months old.

“Quick-Wee” method, Kaufman et al, BMJ 2017;357:j1341, 354 infants aged 1-12mos

With patient supine, suprapubic skin was rubbed with gauze soaked in cold saline. 31% voided within 5 minutes using Quick-Wee vs. 12% in the standard collection group.

Finally, Naimer in Pediatr Emerg Care 2017;33:446 describes cutting a slit in an infant’s diaper to push the urine collection bag through when obtaining a bag urine. This both helps to secure the bag and allows parents and nurses to see when the specimen has been obtained.
