Objective: To assess the relationship between subjective and objective urinary dysfunction in patients with Parkinson’s disease (PD), multiple system atrophy (MSA), and progressive supranuclear palsy (PSP), and to determine the correlation between clinical characteristics and subjective urinary dysfunction or post-void residual urine volume.
Background: In clinical practice urinary dysfunction is generally assessed by subjective urinary dysfunction questionnaires and sonographic post-void residual urine volumes. However, subjective urinary dysfunctions are weakly correlated with objective tests.
Methods: A total of 196 de novo patients with PD, MSA, and PSP without urological and gynecological disorders were enrolled using each clinical diagnostic criterion. Data were collected on sonographic post-void residual urine volumes and urinary symptoms using questionnaires. All patients were also assessed with motor symptoms, cognitive measurements, other non-motor symptoms, and renal functions.
Results: Abnormal post-void residual urine volume was found in 10 out of 163 PD patients, 6 out of 14 MSA patients, and 1 out of 19 PSP patients. The MSA group showed signiﬁcantly higher post-void residual urine volume compared to the PD and PSP groups. Symptoms of the sense of incomplete emptying, weak urine stream, and nocturia were strongly correlated with post-void residual urine volume. Post-void residual urine volume was positively related to autonomic symptoms, other non-motor symptoms, patient activities of daily living, and negatively related to renal function.
Conclusions: In conclusion, signiﬁcantly increased sonographic post-void residual urine volumes were observed in a small portion of early de-novo drug naive Parkinsonian patients, especially in MSA patients. Objectively measured post-void residual urine volume was significantly related to subjective urinary dysfunctions and other autonomic dysfunctions. Therefore, voiding problems due to urinary dysfunction requires attention and investigation of urinary dysfunction in PD patients.
