Summary
This study established normal uroflowmetric parameters for healthy Thai adults, finding that peak flow rates are higher in younger individuals and females. These findings are crucial for assessing bladder function in clinical settings.
Area of Science:
- Urology
- Physiology
Background:
- Uroflowmetric parameters are influenced by various factors including age, sex, and physiological variations.
- Establishing normative data is essential for diagnosing lower urinary tract conditions.
Purpose of the Study:
- To measure uroflowmetric parameters in healthy Thai subjects.
- To compare these parameters across different age groups and genders.
- To investigate correlations between peak flow rate and other voiding parameters.
Main Methods:
- A cross-sectional study involving 140 healthy Thai subjects (young adults and pre-elderly).
- Subjects were divided into two age groups (18-30 and 50-60 years) and by gender.
- Uroflowmetry was performed using a Dantec Urodyn 1,000, with residual urine measured by ultrasonography.
Main Results:
- Younger adults exhibited significantly higher peak and mean flow rates compared to pre-elderly subjects.
- Females demonstrated significantly higher peak and mean flow rates than males.
- A significant positive correlation was found between peak flow rate and voided volume.
Conclusions:
- This study provides normal uroflowmetric reference values for Thai young adult and pre-elderly populations.
- Age and gender significantly influence uroflowmetric parameters.
- These normative data are valuable for urological assessments of bladder function.
