Objective  To explore the application value of American Urological Association symptom index (AUA-SI) score in female patients of type 2 diabetes mellitus with neurogenic bladder.

  Methods  This study included 289 female patients with type 2 diabetes who were hospitalized in our hospital from July 2015 to July 2018. To each of them, residual urine volume (RUV) test, fundus test, and random urinary albumin creatinine ratio (UACR) test were performed, and a questionnaire survey was conducted using AUA-SI scale. Multivariate logistic regression was used to analyze the risk factors of diabetic neurogenic bladder (DNB) in women with type 2 diabetes.RUV≥100 mL was used as the diagnostic golden standard for DNB, and the patients were divided into DNB group and non-DNP group. The ROC curve was used to evaluate the diagnostic performance of AUA-SI. Linear regression was used to test the linear trend of AUA-SI score with diabetic retinopathy stage and diabetic nephropathy stage.

  Results  The levels of the fasting plasma glucose, hemoglobin A1c (HbA1c) and AUA-SI score in DNP group were higher than those in non-DNP group (P < 0.001). Multivariate logistic regression analysis showed that AUA-SI score had the greatest predictive value for the occurrence of DNB 〔odds ratio (OR)=1.876, P < 0.001〕.The area under the curve (AUC) was 0.843, P=0.000, 95% confidence interval (CI) (0.799, 0.888). The optimal diagnostic threshold was 7.5, the corresponding sensitivity was 0.747, and the specificity was 0.822. There was a positive correlation between the severity of AUA-SI score and the stage of diabetic retinopathy and diabetic nephropathy (P < 0.01).

  Conclusion  AUA-SI score can be used to screen female patients with DNB, while it seems parallel to the severity of DNP, diabetic retinopathy and diabetic nephropathy.
