The International Continence Society describes lower urinary tract symptoms (LUTS) as the subjective indicator of a disease or change in condition as perceived by the patient, caregiver, or partner that may lead him/her to seek care from healthcare professionals. 1 These symptoms, however, are usually qualitative and cannot be reliably used to make a definitive diagnosis and care plan. Various clinical tools are available ranging from simple to complex, including a thorough history, physical examination, symptom questionnaires, voiding diaries, pad tests, uroflowmetry, postvoid residual measurements, and urodynamics. The voiding diary is a simple, noninvasive method to objectively quantify a patient’s usual voiding behavior. Its utility as a diagnostic tool is not limited to initial quantification of symptoms, but can be used to follow the effectiveness of treatments and is considered to be a foundation in the initial management of the neurogenic patient. 2
