Summary
Uroflowmetry effectively assesses urinary flow rate in men with urethral strictures. Treatment significantly improves maximum urinary flow rate, aiding in predicting intervention needs and confirming treatment success.
Area of Science:
- Urology
- Medical Devices
- Diagnostic Tools
Background:
- Urethral strictures significantly impair bladder voiding function.
- Objective assessment of urinary flow is crucial for diagnosis and treatment monitoring.
Purpose of the Study:
- To evaluate the efficacy of uroflowmetry in assessing men with urethral strictures.
- To determine the impact of urethral dilatation on urinary flow parameters.
Main Methods:
- Fifty men with urethral strictures underwent uroflowmetry before and after urethral dilatation.
- A DANTEC 2100 mictometer and uroflow transducer were utilized for data collection.
- Statistical analysis included t-paired comparison, McNemar test, and one-way ANOVA.
Main Results:
- A significant increase in maximum urinary flow rate (P < 0.01) was observed post-dilatation.
- 64% of patients improved to normal or overlap zones in voiding classification post-treatment.
- No significant urodynamic differences were found between different urethral stenosis etiologies.
Conclusions:
- Uroflowmetry provides reliable data on voiding ability in urethral stricture patients.
- Maximum flow rate is a valuable predictor for the necessity of urethral dilatation.
- Uroflowmetry offers objective evidence of treatment efficacy for urethral strictures.
