Quick-Wee Versus Bladder Stimulation System to Collect Midstream Urine From Pre-continent Infants

Not Applicable
Completed
Conditions
Urinary Tract Infections
Interventions
Other: bladder stimulation
Other: Quick wee
Registration Number
NCT04587999
Lead Sponsor
Fondation Lenval
Brief Summary

Urinary tract infections are common in infants. Obtaining urine from pre-continent children can be difficult and time consuming. The method of collection must balance reliability, speed, low rate of contamination, and invasiveness.

According to the American Academy of Pediatrics, midstream clean-catch urine is an acceptable method to diagnose urinary tract infections. However, it is impractical in pre-continent children.

Recently, two quick, safe and effective methods have been reported in the literature:

* The Quick-wee method: it consists in stimulating the suprapubic area with a cold and wet compress to obtain urines.

* The bladder stimulation method : the child is held under the armpits with legs dangling and a physician taps the suprapubic area and massages lumbar area alternatively.

However, advanced age, high weight, and level of discomfort during bladder stimulation were significantly associated with failure to obtain urines.

Detailed Description

Urinary tract infections (UTI) are common in infants. The diagnosis of a UTI has important implications for follow-up, and delayed treatment can result in morbidity, including renal scarring and serious bacterial infection.

Obtaining urine from pre-continent children can be difficult and time consuming, the method of collection must balance reliability, speed, low rate of contamination, and invasiveness The actual guidelines recommend suprapubic aspiration or bladder catheterization for collection of urine sample in pre-continent children, but these methods are invasive.

The most common way to collect urines in infants is the use of a sterile collection bag. This is an easy technique, but time consuming and responsible for high rate of contamination, leading to false positives.

According to the American Academy of Pediatrics, midstream clean-catch urine is an acceptable method to diagnose urinary tract infection. However, it is impractical in pre-continent children.

Recently, two quick, safe and effective methods have been reported in the literature:

* The Quick-wee method: it consists in stimulating the suprapubic area with a cold and wet compress to obtain urines.

* The bladder stimulation method: the child is held under the armpits with legs dangling and a physician taps the suprapubic area and massages lumbar area alternatively.

However, advanced age, high weight, and level of discomfort during bladder stimulation were significantly associated with failure to obtain urines.

Futhermore, even if urine collection in pre-continent children most often concerns urinary tract infections, these techniques could also be used to look for a metabolic abnormality, an uropathy or a nephropathy (urine electrolyte concentrations, proteinuria, hematuria).

The aim of the study is to compare the effectiveness of two non-invasive midstream urine collection methods in pre-continent children : "the Quick-Wee method" and "the Bladder stimulation method".

The investigators will also compare in the two groups the time required to obtain urine sample, the comfort of the infant during urine collection and the quality of urines.

Finally, for each technique will be analyzed the risk factors associated with failure in obtaining urine sample

Primary Outcome Measures
NameTimeMethod
volume of urine collection to measure the effectiveness of two techniquesat the end of intervention completion, an average 30 minutes

measure of success of the urine collection technique is determined by collecting at least 2 millimeters of urine in less than 5 minutes

Secondary Outcome Measures
NameTimeMethod
time needed to obtain urinesat the end of intervention completion, an average 30 minutes

measure of times needed to obtain urines in minutes and seconds

patient comfortthrough intervention completion, an average 30 minutes

pain is measured by Evaluation ENfant DOuLeur (EVENDOL) scale while the technique is performed. EVENDOL is a pain scale for children under 7. A pain scale validated for children from birth to 7 years. Score ranges from 0 to 15.

Treatment threshold: 4/15.

collection of patient data to define risk factors associated with the failure of the bladder stimulation techniquesthrough intervention completion, an average 30 minutes

collection patient data : pain, weight, sex, age, last food and time since last collect urine The goal is to define potential risk factors to failure urine collection (urinary sample quantity \< 2 millimeters or no urinary sample collected)

Bacterial contamination rates of urine samplesat 48 hours after inclusion

Measure of bacterial contamination of urine sample is by:

* numeration the growth of two or more micro-organisms,

* Or numeration the presence of a non-uropathogenic germ (lactobacilli, Staphylococcus Coagulase negative, Corynebacterium),

* or numeration a bacteriuria\> 0 colony forming unit(CFU)/millimeters (mL) but \<10˄4 CFU / ml for bladder catheterization and \<10˄5 CFU / mL for clean catch urine collected by bladder stimulation, or leukocyturia \<10˄4 / mL
