Introduction: To evaluate the validity and reliability of the Turkish version of the Symptoms of Lower Urinary Tract Dysfunction Research Network Symptom Index-10 (LURN SI-10).
Materials and methods: In this, single-centre study, patients between 18 and 65 years old, who were suffering from lower urinary tract symptoms (LUTS) without any known urinary tract disease and on no medication, were enrolled. The control group consisted of participants, who were admitted to our clinic suffering from any complaint except LUTS and met all of the other inclusion and exclusion criteria. Participants’ demographics such as age, sex, and level of education were recorded. The Turkish version of the LURN SI-10, International Prostate Symptom Score (IPSS) and Overactive Bladder Questionnaire (OAB-V8) were administered to all participants. Construct validity was evaluated by confirmatory factor analysis and concurrent validity was evaluated with correlations to similar measures. Internal consistency (Cronbach's alpha) was used to establish the scale's internal consistency reliability.
Results: A total of 164 participants were included in the final analysis. Of those, 57% were male. The individuals were identified as being in the “patient group” (n = 86) and a “control group” (n = 78). The mean age was 48.24 ± 14.30 years. The median total LURN SI-10 scores of patient group and control group were 12.0 (9-18.25) and 4.0 (2.75-6), respectively. The LURN SI-10 questionnaire showed a high correlation with the IPSS and the OAB-V8 questionnaires (r: 0.761; p: 0.001; r: 0.737; p: 0.001, respectively) in concurrent validity analysis. Cronbach’s alpha coefficient of the LURN SI-10 was 0.850.
Conclusions: This promising measurement tool can be used to evaluate LUTS in Turkish women and men. Further studies should be conducted to assess the clinical usefulness of this questionnaire.
