ABSTRACT
Objective To explore the characters of lower urinary tract symptoms (LUTS) in patients with Parkinson's Disease (PD).Methods From Oct 2013 to Jun 2016,after evaluating of movement disorder by modified Hoehn-Yahr(H-Y) scale and LUTS by international prostate symptom score (IPSS),urodynamic study was performed in PD patients with LUTS.The incidence of every symptom of LUTS,the relationships between the IPSS categories and urodynamic study were analyzed.Results 64 patients (containing 26 male and 38 female) with 40-80 (62.7 ± 10.2) years old were included.2,4,30,19,12 and 6 patients were belonged to modified H-Y scale 1-4,respectively.Frequency (50 patients,78.1％) was the most common LUTS,while frequency all day (20 patients,31.3％) was the most common symptom for the most severe LUTS.IPSS was 1 7.5 ± 7.8 (4-35) and quality of life was 5.1 ± 0.6 (4-6) for the patients.There was no significant correlation between modified H-Y scale and IPSS (P ＞ 0.05).According to the criteria of IPSS,28 patients (43.8％) only had irritative symptoms,3 patients (4.7％) only had obstructive symptoms,while 26 patients (40.6％) had mixed symptoms and 7 patients (10.9％) belonged to no one.Urodynamic study showed 11 patients (39.3％) with only irritative symptoms had detrusor overactivity(DO),6 patients (23.1％) with mixed symptoms had DO + bladder outlet obstruction (BOO) or DO + detrusor underactivity,however,there was no one with BOO in the three patients with only obstructive symptoms.Conclusion Frequency was the most common LUTS,while frequency all day was the most common symptom for the most severe LUTS in PD patients.Irritative and mixed symptoms were common in PD patients with LUTS,but the urodynamic results were not consistent with the category of LUTS in most of the patients.LUTS severity was not correlated with movement disorders in PD patients.
