Abstract

OBJECTIVE:

Nocturia is a frequent complaint in the population of idiopathic Parkinson's disease patients (IPD). The consequences of nocturia in the IPD population are at high importance as these patients have motor problems and therefore a risk of nocturnal fall. The aim of the study was to determine the mechanism of nocturia in patients with MPI, by determining the prevalence of nocturnal polyuria (NP) in this population.

METHOD:

A prospective study by bladder diary was conducted on 70 consecutive IPD patients consulting for regular neurological follow-up at a non-severe stage. Nocturia was defined as 1 or more awakenings to urinate. Two definitions of NP were used: nocturnal diuresis 33% or higher of the total diuresis (NUV33), which is the ICS (International Continence Society) definition, and nocturnal diuresis 90 mL/h or higher (NUP90).

RESULTS:

The mean patient age was 71 years (45-86, sex ratio 33/30). On average, patients were diagnosed for IPD 6.76 years earlier. The prevalence of NP was 64.5% according to NUV33 definition, and 17.7% according to NUP90 definition. Among patients with nocturia, the prevalence of NP was 66% (NUV33) and 21.5% (NUP90). No association was observed between disease duration of the IPD and the prevalence of nocturia and NP. Patients 70 years and older were more likely to have NP as defined by NUV33 than those less than 70 years (72.7% versus 55.17%, P=0.015). Men had more frequently nocturia (33.3% versus 20.7%, P=0.027).

CONCLUSIONS:

The prevalence of NP and nocturia was analyzed in patients with IPD at a non-severe stage. This prevalence was not higher than in the general population of the same age. The mechanism of nocturia in patients with IPD is not unambiguous and therefore requires to be explored by a bladder diary.
