title: A new technique for fast and safe collection of urine in newborns.
abstract: OBJECTIVE
  To describe and test a new technique to obtain midstream urine samples in newborns.
  
  
  METHODS
  This was a prospective feasibility and safety study conducted in the neonatal unit of University Infanta Sofía Hospital, Madrid. A new technique based on bladder and lumbar stimulation manoeuvres was tested over a period of 4 months in 80 admitted patients aged less than 30 days. The main variable was the success rate in obtaining a midstream urine sample within 5 min. Secondary variables were time to obtain the sample and complications.
  
  
  RESULTS
  This technique was successful in 86.3% of infants. Median time to sample collection was 45 s (IQR 30). No complications other than controlled crying were observed.
  
  
  CONCLUSIONS
  A new, quick and safe technique with a high success rate is described, whereby the discomfort and waste of time usually associated with bag collection methods can be avoided.
