A modified device to facilitate flow measurements during voiding cystometry studies in infants

Area of Science:

• Pediatric Urology
• Medical Device Development

Background:

• Urodynamic studies (UDS) in infants present significant technical challenges, particularly in standardized urine flow collection.
• Current methods for infant UDS are often difficult to perform and lack standardization.

Purpose of the Study:

• To introduce a novel, simple device designed to facilitate urine collection during the voiding phase of infant UDS.
• To improve the feasibility and standardization of UDS in pediatric patients.

Main Methods:

• Development of a simple, disposable device utilizing an adhesive urine-collection bag.
• Connection of the collection bag via a tube to a flowmeter for accurate flow measurement during UDS.

Main Results:

• The device was successfully used in eleven infants aged 4-23 months, enabling complete UDS.
• A definitive diagnosis was achieved for all infants who underwent the study using this method.

Conclusions:

• The developed device is inexpensive, disposable, and readily available in pediatric clinics.
• This innovation makes comprehensive UDS achievable in infants, overcoming previous technical limitations.
