BackgroundScreening for asymptomatic urinary retention (AUR) in older adult men at hospital admission to the internal medicine department has never been studied.ObjectivesTo assess the incidence of AUR in older adult men at hospital admission, its risk factors, and its outcome.MethodsThe study comprised 111 older adult men aged ≥ 75 years who were admitted to three internal medicine departments. All men underwent post-void residual (PVR) urine volume measurement on the morning following admission by using a portable ultrasound bladder scan. AUR was defined as a PVR urine volume of ≥ 200 ml without symptoms. Men with AUR had a follow-up phone call concerning symptoms and urinary catheter status30 days following hospitalization.ResultsSeven (6.3%) men had AUR. Relative to the 104 men without AUR, they had significantly higher prevalence of severe dependency (6/7 vs. 33/104, 85.7% vs. 31.7%, (P = 0.007), cognitive impairment (5/7 vs. 19/104, 71.4% vs. 18.3%, P = 0.005), and use of anticholinergic agents (4/7 vs. 19/104, 57.1% vs. 18.3%, P = 0.033). A urinary catheter was inserted in one man (14.3%), but it was removed later during hospitalization. No symptoms were reported and no urinary catheter was inserted following hospitalization in men with AUR.ConclusionsAUR in older adult men at hospital admission is uncommon and has a favorable outcome. Hence, screening for AUR in all older adult men at admission is not recommended, but it may be considered in severely dependent older adult men with cognitive impairment who use anticholinergic agents.
