Introduction Lower urinary tract symptoms (LUTS) in children are common. In 2005, Akbal et al published the dysfunctional voiding and incontinence scoring system (DVAISS) to assess patient's symptoms. Our study aimed to determine the value of this scoring system for predicting the severity and clinical course of voiding abnormalities in children and adolescents.

Material and Methods Patients' symptoms were scored using the DVAISS in children and adolescents with LUTS presenting for the first time to our pediatric urology department between January 2010 and December 2015. We correlated the calculated score with voiding volume, clinical course, and outcome.

Results A total of 168 patients (113 boys, 55 girls; age 5–18 years) with isolated LUTS were included. In 53 patients (group 1), the DVAISS score was less than or equal to 8.5 and in the other 115 patients (group 2), the score was greater than 8.5 suggestive for relevant voiding abnormalities. Patients in group 1 showed a significantly higher average voiding volume (200 vs. 110 mL, p = 0.001). The median time for symptom resolution was significantly higher in group 2 than group 1 (14 vs. 8 months; p = 0.018). The severity of LUTS could be determined by these parameters.

Conclusion Based on the DVAISS, a prediction of the clinical course and approximate treatment duration is possible. Therefore, the DVAISS is useful to assess LUTS in children and is also a valuable tool in rating the severity of the disease. It is also a quite precise predictor of the time needed to resolve the symptoms.

简介 儿童下尿路症状 (LUTS) 很常见。2005 年，Akbal 等人发表了功能失调的排尿和失禁评分系统 (DVAISS) 来评估患者的症状。我们的研究旨在确定该评分系统在预测儿童和青少年排尿异常的严重程度和临床过程中的价值。

材料和方法 使用 DVAISS 对 2010 年 1 月至 2015 年 12 月期间首次到我们儿科泌尿科就诊的 LUTS 儿童和青少年患者的症状进行评分。我们将计算的评分与排尿量、临床过程和结果相关联。

结果 共纳入 168 例孤立性 LUTS 患者（113 名男孩，55 名女孩；年龄 5-18 岁）。在 53 名患者（第 1 组）中，DVAISS 评分小于或等于 8.5，而在其他 115 名患者（第 2 组）中，评分高于 8.5，提示相关排尿异常。第 1 组患者的平均排尿量显着增加（200 对 110 mL，p  = 0.001）。第 2 组症状消退的中位时间明显高于第 1 组（14 个月 vs. 8 个月；p  = 0.018）。LUTS 的严重程度可以由这些参数确定。

结论 基于 DVAISS，临床过程和大致治疗持续时间的预测是可能的。因此，DVAISS 可用于评估儿童 LUTS，也是评估疾病严重程度的宝贵工具。它也是解决症状所需时间的一个相当精确的预测指标。
