title: Psychometric validation of the Spanish version of the USS-PROM questionnaire for patients who undergo anterior urethral surgery.
abstract: OBJECTIVE
  To translate into Spanish and validate the Urethral Stricture Surgery Patient-Reported Outcome Measure (USS-PROM) questionnaire, assessing its psychometric properties and determining its suitability for clinical use in our community. We also assessed the potential changes in ejaculatory function using the Male Sexual Health Questionnaire-Ejaculatory Dysfunction (MSHQ-EjD).
  
  
  METHODS
  A systematic translation of the British version was performed. Patients scheduled for anterior urethral stricture surgery between September 2014 and September 2015 were prospectively included in the study. All patients completed the questionnaire before and after the surgery. We conducted an in-depth psychometric study of the questionnaire.
  
  
  RESULTS
  We assessed the responses of a total of 40 patients. The questionnaire showed its validity, presenting an excellent negative correlation between the voiding symptom scores and the maximum flow (r=-0.6, P<.001), and also showed significant improvement in the EQ5D-VAS (visual analogue scale) and the time trade-off. For internal consistency, the Cronbach's alpha was 0.701. For the test-retest reliability, the overall intraclass correlation coefficient (ICC) was 0.974, and the ICC for each item separately ranged from 0.799 to 0.980. We observed significant improvement in all items regarding urinary symptoms and health-related quality of life (P<.001), thereby demonstrating the response capacity to changing the questionnaire. There were no significant changes in the MSHQ-EjD.
  
  
  CONCLUSIONS
  The Spanish version of the USS-PROM questionnaire is a valid instrument for quantifying changes in voiding symptoms and the health-related quality of life of patients undergoing anterior urethral surgery.
