排尿性膀胱尿道攝影（voiding cystoureterography,VCUG）
雖然膀胱輸尿管逆流屬於泌尿系統疾病，但長期反覆感染和腎臟損傷可能影響兒童的生長發育，導致營養不良和發育遲緩。
Although vesicoureteral reflux (VUR) is a urinary tract disorder, the long-term consequences of recurrent infections and kidney damage can significantly impact a child's growth and development, leading to malnutrition and developmental delay.
主要目的是檢查尿液是否會從膀胱逆流回輸尿管，甚至腎臟，也就是所謂的「膀胱輸尿管逆流」，逆流可能導致反覆泌尿道感染，甚至腎臟損傷，因此VCUG對於評估逆流的嚴重程度、診斷及治療非常重要。
The primary purpose of a voiding cystourethrography (VCUG) is to evaluate for vesicoureteral reflux (VUR), a condition where urine flows backward from the bladder into the ureters and possibly the kidneys. VUR can lead to recurrent urinary tract infections and even kidney damage. Therefore, VCUG is crucial for assessing the severity of reflux and guiding subsequent diagnosis and treatment.
檢查前通常會讓病童禁食，避免嘔吐，過多飲水反而可能增加膀胱壓力，影響檢查結果，且VCUG檢查會使用顯影劑，藉由X光來觀察尿液流動的情況。
Before the voiding cystourethrography (VCUG) procedure, children are typically asked to fast to prevent vomiting. Excessive fluid intake can increase bladder pressure and affect the test results. Additionally, a contrast agent is used during the VCUG to visualize the flow of urine under X-ray.
