Abstract

Abstract : Objective: The aim of the present study was to examine factors of nocturnal polyuria and blood pressure variability in male patients with lower urinary tract symptoms (LUTS) who were treated. Methods: Two hundred and forty‐two male patients with LUTS who were treated recorded frequency volume charts. We investigated their urinary condition and characteristics, medical history, and medications. Thirty‐four of these patients underwent ambulatory blood pressure monitoring (ABPM) for 24 hours to evaluate blood pressure variability. Results: In the present study, 194 patients (80.2%) had nocturia and 136 (56.2%) had nocturnal polyuria (NP). Among patients with nocturia (≥2 voids/night), 130 (67.0%) had nocturnal polyuria, and 26 of those with nocturia (13.4%) had reduced functional bladder capacity. The use of 2 or more antihypertensive medications was significantly higher in the NP than non‐NP group (22.8% vs. 12.3%; P = .035). Significantly more patients in the NP group had non‐dipping blood pressure ( P = .037). Non‐dipping blood pressure was considered a potential factor for NP. Conclusion: We suggest that treatment of non‐dipping blood pressure may improve NP.
