INTRODUCTION: The aim of the study was to validate the Ureteral Stent Symptom Questionnaire (USSQ) in Danish for patients with indwelling ureteral stents.
METHODS: The linguistic validation of the original USSQ was performed following standardised multi-step translation procedures. Seventy patients with indwelling ureteral stents were asked to complete the Danish USSQ one and two weeks after stent placement and four weeks after stent removal.
RESULTS: A total of 65 patients (92.9%) completed the USSQ. Statistical evaluation revealed good internal consistency in all domains except work performance. Satisfactory convergent validity (less-than -0.4 or greater-than 0.4) was demonstrated for urinary symptoms, body pain and global quality of life. The test-retest reliability-coefficient was statistically significant for urinary symptoms, general health, pain and sexual matters. Inter-domain associations were positive and monotone for all subscales. All sub-scores, except sexual matters, significantly decreased from one week after stent insertion to four weeks after stent removal (p less-than 0.001).
CONCLUSION: The Danish USSQ is a reliable and valid instrument with which to evaluate urinary symptoms and general health in patients with indwelling ureteral stents.
