Abstract

Introduction and Background: Benign Prostatic Hyperplasia (BPH) affects the micturition cycle. Lower urinary tract symptoms (LUTS) refers to storage symptoms such as urinary frequency, urgency, urge urinary incontinence and nocturia. Surgical options for bladder outlet obstruction (BOO) are currently offered for symptomatic improvement. However, 30% of patients report persistent LUTS after BOO procedures. Neuroplasticity induced by BPH and BOO can be contributory in these men, having different brain activation patterns during the micturition cycle. Our multimodal functional Magnetic Resonance Imaging (fMRI) study will identify for the first time, structural and functional brain contributions to LUTS in men with BPH and BOO at baseline and following BOO procedures. We hypothesize that men with symptomatic BPH with persistent LUTS following BOO procedures have a distinct brain activation pattern in regions of interest (ROIs) of the micturition cycle. Methods: Male patients older than 45 years of age undergoing BOO procedures will be enrolled and categorized in two groups. Group 1: patients with BPH with significant improvement in storage symptoms after BOO procedures. Group 2: patients with BPH with persistent storage symptoms after BOO procedures. Our control group are male patients without LUTS undergoing radical prostatectomy. Patients will complete subjective questionnaires and post void residual at clinic visits. BOLD signals at full urge will be measured at baseline and following BOO procedures. All patients will undergo fMRI studies at baseline and at 6 months. Clinical data will be correlated to BOLD signal changes as well as to structural changes in white matter tracts. Ethics and dissemination: After IRB approval, patients will be recruited and properly consented before enrolling to this study. Results of neural contribution to lower urinary tract symptoms will be presented at national and international meetings and will be published in scholarly journals.
