About this study

As a part of the urodynamic studies, urinary catheterization is inserted to measure residual urine, however, it has shown to be an invasive procedure, cause urinary tract infection, and traumatic experience. Bladder scan has been introduced as an alternative and non-invasive method to measure urine residual in the bladder.

Read the detailed description

Functional urinary disorders are common as more than 15% of children are diagnosed. During the normal course of urinary tract development, bladder and urinary sphincter develop by 2 to 4 years old, and by five years old, the tract is completely developed. The underdevelopment of the urinary tract may lead to complications of the bladder and kidneys along with social impairment. Therefore, the diagnosis is critical as an early diagnosis can prevent long term complications. To diagnose, newborns undergo basic urinalysis, urine culture examination, blood creatinine analysis, and kidney and bladder ultrasound. If any abnormalities are present at the under the age of five, it is recommended that they are followed up on a regular basis. Also, urodynamic studies should be performed every year along with others for early identification and intervention. Studies have shown that UDS (urodynamic studies) significantly reduce the deterioration of the bladder and kidney and the need for operation such as bladder dilation.

As a part of the urodynamic studies, urinary catheterization is inserted to measure residual urine, however, it has shown to be an invasive procedure, which can cause urinary tract infection. The bladder scanner is an ultrasonic imaging device that has been developed for non-invasive measurement of residual volume in the bladder. The images and measurements are obtained by applying a probe onto the abdomen. It constructs 12 cross-sectional images at 15 degree interval using the reflection signals from urine in the bladder and extracts the position of the bladder wall.

The objective of the study is to assess the validity of existing pediatric algorithms for diagnosing neurogenic bladder and evaluate the accuracy of measuring the post-void residual volume between the ages of 0 to 6 years old.

It hypothesizes that when the portable bladder scanner (Bladder Scanner, Biocon-900) is used in pediatric population between the ages of 0 to 3 years old will show greater difference in infused and scanned volume than 4 to 6 years old.

  • Bladder scanDevice

    Also called Bladder Scanner, Biocon-900

    Bladder Scanner, or Biocon-900 is an ultrasonic imaging device that has been developed to measure post-void residual volume of the bladder non-invasively. The images and measurements are obtained by applying a probe onto the abdomen (i.e. bladder). As it scans, the scanner constructs 12 cross-sectional images at 15 degree interval using the reflection signals from urine in the bladder and extracts the position of the bladder wall as well. During urodynamic studies, the bladder scan will measure the infused volume in order to assess difference between the infused and scanned volumes.

Questions about this trial

What is this clinical trial studying?

An observational study of Neurogenic Bladder and Detrusor Underactivity, run by Seoul National University Hospital at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 May 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Scanned bladder volume (time frame: Immediately after procedure (urodynamics studies)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 May 2021; AzTrials last refreshed its copy on 1 Nov 2026.
