Urolithiasis significantly affects patient quality of life, yet the global standard of care predominantly focuses on achieving a stone free status, often ignoring patient reported outcomes. Currently, there are no specific measures available to assess the quality of life in the Polish population suffering from kidney stones. Therefore, this study aimed to develop and validate the Polish version of the Wisconsin Stone Quality of Life Questionnaire.
The translation of WISQOL was carried out in accordance with the best available guidelines. Patients treated for kidney stones at a tertiary centre were recruited and completed both POL-WISQOL and SF36 questionnaires. Comprehensive analyses were conducted to assess internal consistency, inter-item and inter-domain correlations, as well as convergent and construct validity. Additionally, test-retest reliability was evaluated to ensure the accuracy and stability of the findings.
A total of 102 participants fully completed both questionnaires and were included in the analysis. The translated survey demonstrated excellent internal consistency (Cronbach's coefficient 0.967) and significant convergent validity (Spearman's correlation = 0.847, p < 0.001). Furthermore, an ANOVA with Tukey's post hoc analysis revealed a significant decline in WISQOL scores between symptomatic and asymptomatic individuals, thereby confirming tool's construct validity.
POL-WISQoL turned out to be a valid disease specific health related quality of life measuring tool. Its widespread utilisation has the potential to shift the standard of care towards patient centered outcomes.
尿石症显著影响患者的生活质量，但全球的护理标准主要侧重于实现无结石状态，往往忽略了患者报告的结果。目前，尚无特定的措施可用于评估波兰肾结石患者的生活质量。因此，本研究旨在开发和验证波兰版威斯康星结石生活质量问卷（WISQOL）。
按照最佳可用指南进行 WISQOL 的翻译。在一家三级中心接受肾结石治疗的患者被招募并完成了 POL-WISQOL 和 SF36 问卷。进行了综合分析，以评估内部一致性、项目间和域间相关性，以及收敛和结构有效性。此外，还评估了测试-重测信度，以确保研究结果的准确性和稳定性。
共有 102 名参与者完整地完成了两份问卷，并被纳入分析。翻译后的调查显示出极好的内部一致性（克朗巴赫系数 0.967）和显著的收敛有效性（斯皮尔曼相关系数为 0.847，p<0.001）。此外，方差分析与 Tukey 事后检验分析表明，在有症状和无症状个体之间，WISQOL 评分显著下降，从而证实了该工具的结构有效性。
POL-WISQoL 是一种有效的特定于疾病的健康相关生活质量测量工具。它的广泛应用有可能将护理标准转向以患者为中心的结果。
