Abstract
Purpose A recent update in International Continence Society (ICS) terminology now recognizes nocturnal polyuria (NP) and diurnal polyuria (DP) as related subcategories of "Polyuria (global symptom)". This study determines the real-world clinical overlap between NP, DP, and 24-h polyuria (24hP) among men with nocturia. Methods Analysis of frequency-volume charts from men >= 18 years with >= 1 nocturnal void(s). Three separate analyses were performed using different rate criteria for NP, DP, and 24hP: (1) urine production > 90 mL/h (extrapolated from a proposed definition for NP); (2) > 125 mL/h (extrapolated from a proposed definition for 24hP [3000 mL/24 h]); and (3) > 1.67 mL/kg/h (extrapolated from the current ICS definition for 24hP [> 40 mL/kg/24 h]). Subjects were categorized as having one of five mathematically permissible phenotypic combinations: (1) isolated NP, (2) isolated DP, (3) NP + 24hP, (4) DP + 24hP, and (5) NP + DP + 24hP. Results 167, 95, and 61 patients were included at criteria 1, 2, and 3, respectively, with 56%, 43%, and 30% of patients demonstrating overlapping phenotypes (i.e., phenotypic combinations 3-5) at cut-offs 1-3, respectively. The prevalence of NP was similar across cut-offs (81-87%), but the prevalence of NP without 24hP was highly threshold-dependent (43-73%). Conclusion Consistent with current ICS terminology, there exists a substantial overlap between NP, DP, and 24hP. As demonstrated in the current study, absolute volume-based criteria for NP/DP/24hP are indeed conducive to the diagnosis of concurrent NP + 24hP, and may be preferred over proportion-based NP criteria when both NP + 24hP are suspected.
