Symptoms can be assessed with the Ureteral Stent Symptoms Questionnaire (USSQ), a validated instrument that evaluates symptoms and quality of life affection. It is an adequate tool to explore ureteral stent impact in six domains with 38 items. Unfortunately, the quantity of items limits its use in the clinical setting. The objective of the present study is to develop and evaluate the validity of a short version of the USSQ which could simplify the evaluation of symptoms in stented subjects. METHODS A previously validated Spanish version of USSQ was self-administrated by patients who underwent endourological procedures. Healthy subjects were enrolled as controls. We determined which items had better correlation with each domain and were used to formulate the M-USSQ. Reliability between original USSQ and M-USSQ was evaluated. Sensitivity to change of M-USSQ was analyzed comparing scores with and without stent. Discriminant validity was evaluated between cases and controls. Statistical analysis were performed with SPSS v.20 and two-sided with p < 0.05 defined as statistically significant. RESULTS Forty four patients were included as cases meanwhile 50 subjects as controls. The M-USSQ was composed by 8 items, every one with a minimal Spearman coefficient correlation of 0.73 (p<0.0001) with its own domain score. Correlation between total score of original USSQ and M-USSQ was 0.95 for cases and controls and 0.92 between cases (Spearman coefficient, p<0.0001). Cronbach's alpha between 8 selected items was 0.73. Cronbach's alpha between M-USSQ score and original USSQ score was 0.85. Sensitivity to change analysis demonstrated significant differences in 6 out of the 8 items when comparing mean scores with and without stent. All M-USSQ items scores were significantly different between cases and controls. Total M-USSQ score was used to classify symptoms in 3 grades: low, moderate and severe. Mean scores of the three groups were statistically significantly different. CONCLUSIONS M-USSQ is an adequate tool to evaluate symptoms associated with ureteral stents. It does not analyze every single aspect of the main domains but reflects the severity of affection evaluated through the original USSQ. It could be an adequate tool to decide which domains need an extensive evaluation through the original USSQ. M-USSQ could be used to simplify ureteral stents affection evaluation and stratify symptoms. Prospective clinical studies are needed to evaluate the clinical application of the questionnaire. © 2014FiguresReferencesRelatedDetails Volume 191Issue 4SApril 2014Page: e770 Advertisement Copyright & Permissions© 2014MetricsAuthor Information Daniel Olvera-Posada More articles by this author David Velazquez More articles by this author Ricardo Castillejos-Molina More articles by this author Christian Villeda-Sandoval More articles by this author Mario Ramirez More articles by this author Eduardo González-Cuenca More articles by this author Carlos Mendez-Probst More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
