We define minimum number times person must void based on their FBC 24-hour urine output as voiding frequency index (VFI). “extra voids”, difference between actual voids 24 hours VFI, (FBCI). purpose study was describe normal mean values for persons without LUTS evaluate how these differ over spectrum lower urinary tract disorders. METHODS: This retrospective 511 patients with who completed diary (BD) symptom score (LUTSS) questionnaire using smartphone app* from 2015-2019. From BD, we extracted (24HVV), FBC, expressed maximum (MVV), (ANV). Based LUTSS, were placed into 4 subgroups; overactive (OAB), incontinence, nocturia dysfunction. Exclusion criteria included incomplete or inaccurate LUTSS entries. VFI calculated ratio 24HVV FBC. FBCI subtracting ANV. subgroup assignments made questionnaire. These OAB, Comparisons calculate normative indices previously published data sets. *weShare® URO Symptelligence.com RESULTS: A total 487 provided adequate BD analysis (table 1). Larger compared found nocturia. CONCLUSIONS: quantitative metric voids” period. Our observations validate commonly recognized pattern among LUTS; before feeling full order avoid being caught social public situation where bathroom not available (anticipatory voids). Empirically, larger FBCI, greater likelihood patient because reasons unrelated related capacity. may be useful studies quantitate effect behavior evaluation treatment prompting research why people often they do.
