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.
