This study aims to evaluate the impact of reminder call intervention on no-shows for urologic procedures in patients identified to be high risk for no-showing. Patients scheduled to undergo a urologic procedure will be randomized into two groups: the intervention group, who receives a series of reminder calls and text messages about appointment details and patient questions prior to the procedure date; and the control group, who receives standard care only. Secondary outcomes include rates of patient re-scheduling and healthcare utilization.
