The BEDTiMe Nocturia Study (Behavior and Exercise or Drug Trial in Men with Nocturia), is a two-site (Atlanta and Birmingham), randomized, clinical trial. The 200 male participants will be stratified by degree of nocturia and urinary flow rate and randomized to three treatment arms: 1) α-blocker therapy alone; versus 2) a standardized, multicomponent behavioral and exercise therapy (M-BET), given with placebo tablets; versus 3) combination therapy (M-BET and α-blockers). The M-BET intervention includes: training in pelvic floor muscle rehabilitation, self monitoring with bladder diaries, and teaching urge suppression and other skills to inhibit detrusor contractions; fluid management strategies; sleep hygiene strategies; and non-pharmacological management of lower extremity edema. Interventions similar to M-BET have shown reductions in nocturia in women with urge urinary incontinence (UI) that exceeded benefit from anticholinergic drug therapy. The use of this intervention in men builds upon strong pilot data from the MINIM trial (Multicomponent Interventions for Nocturia in Men; VA GRECC Pilot, VA Medical Research Services) and the ongoing study Behavioral Treatment For Overactive Bladder In Men (VA RR&D B02-2489R, Burgio, PI).
