Longitudinal changes in patient‐reported outcomes after artificial urinary sphincter implantation

OBJECTIVE: To evaluate the time course of lower urinary tract symptoms (LUTS) after artificial urinary sphincter (AUS) implantation based on individual longitudinal changes of patient-reported outcomes. METHODS: This retrospective study included 66 male patients with severe urinary incontinence who were treated with primary AUS implantation between 2009 and 2019. International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) and International Prostate Symptom Score (IPSS) questionnaires were used to evaluate continence status and LUTS preoperatively, 1, 3, and 12 months after activation, and then annually.
