Influencing factors for over active bladder syndrome in patients with cerebral small vessel disease / 中华老年心脑血管病杂志

ABSTRACT

Objective To explore the influencing factors of over active bladder(OAB)in patients with cerebral small vessel disease(CSVD)and its correlation with CSVD imaging markers.Meth-ods A total of 163 elderly CSVD patients admitted in our hospital from January 2021 to Decem-ber 2022 were enrolled and divided into OAB group(37 cases)and non-OAB group(126 cases)based on the results of OAB rating scale.Mini-mental State Examination(MMSE)score,Fazekas scale score,and total CSVD burden score were recorded and compared between the two groups.Results The OAB group had older age,higher urinary frequency,larger proportions of nocturia,urgency,and urge incontinence ratio,increased Fazekas score,periventricular white matter hyper-intensity(PWMH)score and deep white matter hyperintensity(DWMH)score,and elevated total CSVD burden score and lower MMSE score than the non-OAB group(P＜0.05,P＜0.01).PWMH score and DWMH score were risk factors for the occurrence of OAB(P＜0.01).The OAB score was positively correlated with Fazekas score,PWMH score,and DWMH score in the CSVD patients(r=0.533,P=0.001;r=0.462,P=0.004;r=0.398,P=0.015).The occurrence of urgency urinary incontinence was positively correlated with Fazekas score and PWMH score in the CSVD patients(r=0.352,P=0.033;r=0.346,P=0.036).Conclusion PWMH and DWMH are risk factors for OAB occurrence in CSVD patients.
