Reality of Urinary Incontinence in Patients with Parkinson's Disease

ABSTRACT

PURPOSE: The study was performed to identify the reality of urinary incontinence (UI) and to evaluate the risk factors developing UI for the patients with Parkinson's disease. MATERIALS AND METHODS: This was the cross-sectional study with interviews using structured questionnaires. The subjects who were 72 patients(male 20, female 52) and their mean age is 70.07+/-20.06(range 54~86) with Parkinson's disease visited the Neurology clinic, from September to November 2005, at one university hospital located in Jeju island. RESULTS: Subjects with restricted mobility were 45, and 13 were in first stage of Hoehn & Yahr stage, 31 were in second stage, 28 were in third stage. Fifty three(73.6%) subjects had experienced UI. Mixed UI was in 32 (44.4%), stress UI 12(16.7%), and urge UI 9(12.5%), respectively. As for risk factors developing UI, female had 1.62 times(OR=1.62, 95% CI=0.47~5.66) more than male, age of 80~86 had 3.20 times(OR=3.20, 95% CI=0.65~15.69) more than age of 54~69, subjects with restricted mobility had 2.75 times(OR=2.75, 95% CI=0.80~9.43) more than subjects without restricted mobility. Group without regular exercise had 2.9 times more than group with regular exercise(OR=2.90, 95% CI=0.92~9.22). Cognitive impairment group had 1.98 times more than normal mental status group(OR=1.98, 95% CI=0.39~9.97). Second stage had 4.91 times(OR=4.91, 95% CI=0.55~43.53) and third stage had 5.68 times(OR=5.68, 95% CI=00.64~50.73) more than first stage in Hoehn and Yahr stage. CONCLUSION: There is a high prevalence(73.6%) of UI in patients with Parkinson's diseases. Mixed UI was the most common type of incontinence. Risk factors developing UI were higher in female, older group, restricted mobility group, group without regular exercise, cognitive impairment group andhigher Hoehn and Yahr stage.
