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-April 2019. The micturation videos of their children were taken during first micturation in the morning of their children's 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 tree months, 20 male children jointed this study. The mean age was 7,5 years (3-13 years), and the mean voiding time was 31 seconds (13-67 seconds) by micturation video. The flow calibration and direction were normal. Although the micturation calibrations of 6 patients with a voiding time of more than 40 seconds 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 6 cases, the voiding videos should be seen at least three 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. In this study, it has been shown that voiding video taken by their parents at home can be used as an objective diagnostic method in the evaluation of voiding time and calibrations of children's voiding functions. This preliminary study evaluates voiding functions of children with micturition videos, thus guiding future studies for evaluation of voiding disorders in children.
