98 patients in each group will be included in the study (Aromatherapy group=49; Control group=49). In addition to the routine treatment and care practices of the unit, aromatherapy will be applied to the patients included in the study group. Aromatherapy application will be applied to all patients by the same researcher. Aromatherapy application will be started 5 minutes before the urodynamic procedure after the patient is taken to the urodynamics room and lavender essential oil will be used with a diffuser until the end of the procedure. Routine treatment and care interventions will be applied to the patients included in the control group during the procedure.
This randomized controlled study is planned to determine the effect of aromatherapy applied to patients in the urodynamic procedure on patients' anxiety and serum cortisol levels.~This study assumes that lavender inhalation in aromatherapy has positive effects on physiological parameters such as blood pressure, heart rate, respiratory rate, serum cortisol level, as well as reducing stress and anxiety.
