    Journal: Neurourol Urodyn; 2011 Sep; 30(7):1258-61. PubMed ID: 21404318.
    Abstract:
    AIMS: To quantitatively evaluate the urinary symptoms at different stages of idiopathic Parkinson's disease (IPD) severity and its relation to urodynamic parameters. METHODS: This study was conducted on 49 patients with probable IPD to quantitatively evaluate their urinary symptoms using International Prostate Symptom Score and urodynamic tests. Four, 10, 29, 5, and 1 cases were classified as stages 1-5, respectively, according to Hoehn and Yahr staging of IPD severity. RESULTS: The most prevailing urinary symptom in IPD was nocturia (77.5%) followed by urgency (36.7%) and frequency (32.6%). Urodynamic tests revealed neurogenic detrusor overactivity in 33 patients (67.3%), detrusor underactivity in 6 patients (12.2%), and 10 (20.4%) patients with normal detrusor function. Irritative symptom index score correlated significantly with disease severity as well as the volume at initial desire to void and maximum bladder capacity meanwhile obstructive symptom index score had no significant correlation with any of the urodynamic parameters or disease severity. Total IPSS symptoms score significantly correlated with quality of life score. The mean of urodynamic parameters did not differ in IPD patients who did or did not receive anticholinergic or dopaminergic drugs. CONCLUSION: The irritative urinary symptoms manifested urodynamically as neurogenic detrusor overactivity are more common in IPD patients than obstructive symptoms. These irritative symptoms deteriorate progressively with the disease severity and significantly affect the quality of life of these patients. The International Prostate Symptom Score is a valuable tool in evaluating the urinary dysfunction in such patients.
