Deep drop: a common finding in uroflowmetry of healthy children and adolescents

This database presents the results of our large-scale cross-sectional study of uroflowmetry tests in healthy children and adolescents. A total of 2299 uroflowmetry curves from 1538 children and adolescents aged 5-18 years were analyzed. Based on the results, we proposed comprehensive criteria for defining “deep drop (DD)” and assess the incidence of DD in the uroflowmetry curves of health subjects. Subsequently, we assessed the accordance with the interpretation of DD with an additional 100 randomly selected uroflowmetry curves from the urology clinic. We hope that this set of criteria will help define staccato uroflowmetry pattern and standardize terminology for future research.
