The LURN Comprehensive Assessment of Self-Reported Urinary Symptoms (LURN CASUS) was developed as a comprehensive questionnaire for both men and women. The instrument was developed as a phenotyping tool to provide granular and precise information on lower urinary tract symptom experience, as well as a resource from which clinical tools and outcome measures could be developed. The items assess a wide range of symptoms including storage, voiding, post-micturition, urgency, incontinence, and abnormal bladder sensations.
Using items from the LURN CASUS, the LURN Symptom Index-29 (LURN SI-29) and the LURN Symptom Index-10 (LURN SI-10) were developed as patient-reported outcome (PRO) measures to assess urinary symptoms in adult men and women. The LURN SI-29 and LURN SI-10 are intended for use among individuals with urinary symptoms in general, including overactive bladder, pelvic floor disorders, stress urinary incontinence, urgency incontinence, mixed incontinence, nocturia, hesitancy, and post-void dribbling. The LURN SI-29 and LURN SI-10 assess urgency, incontinence, voiding difficulty, nocturia, pain, frequency and post-micturition symptoms over the past 7 days.
The LURN SI-29 and SI-10 are copyrighted and freely available for use in their current form in the English language. All translation requests are managed by Arbor Research Collaborative for Health.
