Introduction The rising incidence of urolithiasis brings along a rise in stone procedures and ureteral stenting with a Double J (DJ) stent. This is associated with side effects and a decrease in quality of life. The Ureteral Stent Symptom Questionnaire (USSQ) measures these stent related symptoms, but is not yet available in Dutch. The aim of this study is to determine the validity of the Dutch version of the USSQ. Materials and methods A total of 75 patients who underwent ureterorenoscopic stone surgery and Blackstar DJ stenting were included in the study. They were asked to complete the Dutch USSQ at three different times. COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) Guidelines were followed for the translation and validation of the Dutch USSQ. Reliability was tested by analyzing internal consistency and test-retest reliability. Validity was evaluated by analyzing responsiveness and construct validity (interdomain associations and convergent validity). Results 42 patients completed the questionnaires. Preliminary results show good internal consistency in all domains. Test-retest reliability was sufficient for urinary symptoms, general health and work performance (ICC 2.1 > 0.70). Correlations on construct validity were moderate or high (ρ ≥ 0.40) and mean scores after stent removal all decreased. Sufficient construct validity and responsiveness was however not demonstrated according to the COSMIN Guidelines, with only 45.83% and 40% of the a priori hypotheses met respectively. Conclusion The preliminary results show that the Dutch version of the USSQ is a reliable instrument for evaluating the DJ stent related morbidity, however its validity is insufficient in light of the COSMIN criteria. Nevertheless, the results are promising with good reliability, significant correlations between the domains and other validated questionnaires and ability to detect change over time.
