Normal urinary flow for girls aged 3-14 years.

Area of Science:

• Pediatric Urology
• Urodynamics
• Medical Diagnostics

Background:

• Uroflowmetry is crucial for assessing lower urinary tract function in children.
• Establishing normative data is essential for accurate interpretation of pediatric uroflowmetry.
• Previous studies may lack comprehensive data for specific pediatric age groups.

Purpose of the Study:

• To establish uroflowmetry norms for healthy girls aged 3-14 years.
• To analyze uroflowmetric parameters (volume, time, flow rates) in relation to age and voided volume.
• To provide statistically validated data for improved differentiation of pathological voiding patterns.

Main Methods:

• Uroflowmetry was performed on 103 healthy girls aged 3-14 using a "Mictiograph" device.
• Participants were divided into two age groups: 3-7 years (N=53) and 8-14 years (N=50).
• Statistical analysis included variance analysis and regression analysis to determine group differences and correlations.

Main Results:

• Statistically significant differences were found between age groups for volume, average flow, and maximum flow.
• Regression analysis revealed correlations between flow rates (average, maximum) and voided volume.
• A linear relationship was observed between age and flow parameters (volume, average flow, maximum flow) in the 8-14 year group.

Conclusions:

• The study provides statistically validated uroflowmetry norms for healthy girls.
• These norms enhance the ability to differentiate normal voiding from pathological conditions.
• Uroflowmetry in girls, supported by these norms, is a reliable diagnostic indicator in pediatric urology.
