Do uroflowmetric findings change by treatment of urinary tract infection in girls with dysfunctional voiding?

Aim: The goal of the study was to evaluate the efficiency of repeated uroflowmetry study in girls who present with dysfunctional voiding with normal radiologic evaluation.Materials and methods: Twenty five children (25 girls with a mean age of 8.9 years) with recurrent urinary tract infection(UTI) and dysfunctional voiding who have normal radiologic evaluation were prospectively evaluated by uroflowmetry tests. Uroflowmetry study was repeated after the UTI treatment in asymptomatic period. Results: Mean urine volume was 254.31 ± 199.49 cc and the mean micturition time was 25.22 ± 15.43 s at the first uroflowmetry. Prolonged micturition time was noted in 8 (32%) patients. At the second uroflowmetry, mean urinevolume was 370.77 ± 217.89 cc, and the mean micturition time was 29.63 ± 26.42 s. Prolonged micturition time was noted in 7 (28%) patients. Flow pattern curve was bell-shaped in 9 patients and abnormal in 16 patients (64%). In the second investigation a normal flow pattern curve was noted in 10 patients and an abnormal pattern in 15 patients.Conclusion: There was no difference between pre- and post-treatment uroflowmetry pattern in patients with dysfunctional voiding. Uroflowmetry investigation is not a very proper way for follow-up.
