Insights
This study establishes normal uroflowmetry (UFM) values for healthy Turkish children, finding higher maximum flow rates in girls and increased values with age. These findings aid in diagnosing lower urinary tract dysfunction (LUTD).
Area of Science:
- Pediatric Urology
- Diagnostic Imaging
- Urodynamics
Background:
- Uroflowmetry (UFM) is a crucial noninvasive test for diagnosing lower urinary tract dysfunction (LUTD).
- Establishing normative data for UFM in pediatric populations is essential for accurate diagnosis.
- Limited data exists for normal UFM values in healthy Turkish children.
Purpose of the Study:
- To determine normal uroflowmetry (UFM) values in healthy Turkish children.
- To establish local reference ranges for key UFM parameters.
- To provide a baseline for diagnosing lower urinary tract dysfunction (LUTD) in this demographic.
Main Methods:
- 162 healthy children (100 girls, 62 boys) aged 5-15 years were enrolled.
- Uroflowmetry parameters including Qmax, Qavg, VV, time to maximum flow, and voiding time were measured using the Inoflow Smart System.
- Children were analyzed based on gender and two age groups (5-10 and 11-15 years).
Main Results:
- Mean maximum flow rate (Qmax) was significantly higher in girls (21.8 mL/s) than boys (17.98 mL/s) (p=0.003).
- Voided volume (VV), Qmax, and average flow rate (Qavg) were significantly higher in the 11-15 age group compared to the 5-10 age group.
- VV, Qmax, and Qavg demonstrated a direct positive correlation with age (p=0.0001 for each).
Conclusions:
- This study provides valuable normative uroflowmetry data for healthy Turkish children.
- The findings highlight gender and age-related differences in pediatric UFM parameters.
- This research contributes to the limited global knowledge base on normal pediatric uroflowmetry patterns.
Objectives:
Uroflowmetry (UFM) is the first-line noninvasive screening test employed in the diagnosis of lower urinary tract dysfunction (LUTD). The purpose of this study was to determine normal UFM values in healthy Turkish children among our local population.
Methods:
A total of 100 healthy girls and 62 healthy boys aged 5-15 years, who applied to İnönü University Turgut Özal Medical Center Pediatrics Polyclinic between February 2021 and January 2022, were included in the present study. The UFM parameters, including maximum flow rate (Qmax), average flow rate (Qavg), voided volume (VV), time to maximum flow, and voiding time, were measured using the Inoflow Smart System UFM Device and the resulting urine flow curve was recorded. The children were compared in terms of the UFM parameters based on their gender and age groups (5-10 years and 11-15 years).
Results:
The mean Qmax value in healthy female children aged 5-15 years (21.8 ± 8.6 mL/s) was significantly higher than in male children (17.98 ± 6.1 mL/s) (p = .003). VV, Qmax, and Qavg values of the children in the 11-15 age group were significantly higher than those in the age group of 5-10 years (p > .05 for each). VV, Qmax, and Qavg values were directly proportional to age (p = .0001, for each).
Conclusions:
We believe that this study adds to the limited knowledge base regarding normal flow patterns in healthy children.
