Uroflowmetry parameters in healthy children between 5 and 15 years old

Abstract

AbstractObjectivesUroflowmetry (UFM) is the first‐line noninvasive screening test employed in the diagnosis of lower urinary tract dysfunction (LUTD). The purpose of this study was to determine normal UFM values in healthy Turkish children among our local population.MethodsA total of 100 healthy girls and 62 healthy boys aged 5–15 years, who applied to İnönü University Turgut Özal Medical Center Pediatrics Polyclinic between February 2021 and January 2022, were included in the present study. The UFM parameters, including maximum flow rate (Qmax), average flow rate (Qavg), voided volume (VV), time to maximum flow, and voiding time, were measured using the Inoflow Smart System UFM Device and the resulting urine flow curve was recorded. The children were compared in terms of the UFM parameters based on their gender and age groups (5–10 years and 11–15 years).ResultsThe mean Qmax value in healthy female children aged 5–15 years (21.8 ± 8.6 mL/s) was significantly higher than in male children (17.98 ± 6.1 mL/s) (p = .003). VV, Qmax, and Qavg values of the children in the 11–15 age group were significantly higher than those in the age group of 5–10 years (p > .05 for each). VV, Qmax, and Qavg values were directly proportional to age (p = .0001, for each).ConclusionsWe believe that this study adds to the limited knowledge base regarding normal flow patterns in healthy children.
