INTRODUCTION: Normal voiding volume, duration, and calibration are related to hydration status and bladder capacity. The aim of this study was to determination of voiding functions especially in male children which known any abnormality of urinary system and urinary complaints by micturition videos.
METHODS: This prospective study was designed in male children who were referred to our department with complaints other than urinary system disorders who had no urinary anomalies. This study was carried with the consent of parents who agree to participate between January and April 2019. The micturation videos of their children were taken during first micturation in the morning of their childrens by parents with smartphones at home. All videos were bring us. Each micturation video was evaluated according to voiding time, flow rate, urine direction, and calibration.
RESULTS: During the 3 months, 20 male children jointed this study. The mean age was 7.5 years (313 years), and the mean voiding time was 31 s (1367 s) by micturation video. The flow calibration and direction were normal. Although the micturation calibrations of six patients with a voiding time of more than 40 s were normal, urinary ultrasound was revealed normal bladder capacity measurement, and no residual urine after micturition and normal urinary tract; all values were within normal limits. In these six cases, the voiding videos should be seen at least 3 times intermittently, if urination time was long, uroflowmetric evaluation was planned.
DISCUSSION AND CONCLUSION: Voiding time and calibration can be safely evaluated with micturition videos filmed by the care-givers of the patients in their natural environment. This preliminary study evaluates normal voiding function with micturition videos, thus guiding future studies for evaluation of voiding disorders in all patients.
