Abstract

Aims: To evaluate the validity and reliability of the Turkish version of the Symptoms of Lower Urinary Tract Dysfunction Research Network Symptom Index-29 (LURN SI-29). Methods: Patients with lower urinary tract symptoms (LUTS) were included in a single-center study between January and April 2021. Patients' demographics, such as age, sex, and level of education, were recorded. The Turkish version of the LURN SI-29 and the International Prostate Symptom Score (IPSS) were administered to all patients, and the Urogenital Distress Inventory (UDI-6) was additionally administered to female patients. Construct validity was evaluated by confirmatory factor analysis. Concurrent validity was evaluated with correlations to similar measures. Internal consistency (Cronbach's alpha) and split-half reliability analyses were used to establish the scale's reliability. Results: A total of 295 participants, 35.3% females and 64.7% males, were included in the final analysis. The mean age was 56.4 ± 11.7 years. The median total LURN SI-29 scores were 38.0 (26–50) and 26.0 (18–43) for female and male patients, respectively. The LURN SI-29 scale showed a high correlation with IPSS and UDI-6 scales (r =.758, p <.001; r =.774, p <.001, respectively) in concurrent validity analysis. Cronbach's alpha coefficient of the scale and all subscales were greater than 0.70 for both female and male patients. Conclusions: This measurement tool can potentially be used to evaluate LUTS in Turkish women and men. Further studies should be performed to reveal the clinical usefulness of this scale.
