Amaç: Vezikoüreteral reflü (VUR) çocukluk çağında en sık görülen üriner sistem anomalisidir. Tanısında altın standart yöntem voiding sistoüretrografi (VSÜG)’dir. Fakat bu yöntem invazivdir ve kontrast madde kullanımı gerektirir. Çalışmamızın amacı çocuklarda VUR tanısı koymada renkli Doppler ultrasonda belirlenen üreteral jet akım açısının noninvazif bir yöntem olarak tanısal değerini araştırmaktır. Materyal-Metot: Bu prospektif kohort çalışmasında VUR tanısını doğrulamak için işeme sistoürografisi planlanan 63 pediyatrik olgu değerlendirildi. Her iki tarafta VUR tespit edilmeyen hastalar kontrol grubu (n=32), en azından tek tarafta VUR tespit edilen hastalar ise VUR grubu (n=31) olarak çalışmaya dahil edilmiştir. Tüm hastalara VSÜG ve Doppler ultrason ile üreteral jet akım açısı ölçümü yapıldı. Başlangıç tanımlayıcı verileri ve üreteral jet akış açıları karşılaştırıldı.
Bulgular: VUR ve kontrol grupları arasında yaş (p=0,278), cinsiyet (p=0,898) ve mesane volümü (p=0,211) açısından anlamlı bir farklılık yoktu. Üreteral jet akım açısı VUR grubunda hem sağ tarafta (p=0,001) hem de sol tarafta (p<0,001) kontrol grubuyla karşılaştırıldığında daha yüksekti. Sonuç: Üreteral jet akım açısı, VUR tanısı konmasına yardımcı olabilecek ipuçları sağlayabilmektedir. Bununla birlikte, bu yeni sonografik belirteci doğrulamak ve geçerliliğini onaylamak için daha geniş serilerde ve daha fazla çok merkezli çalışmaların yürütülmesine ihtiyaç bulunmaktadır.

Objective: Vesicoureteral reflux (VUR) is the most common urinary system anomaly in childhood. The gold standard method in diagnosis is voiding cystourethrography (VCUG). However, this method is invasive and requires the use of contrast media. The aim of our study is to investigate the diagnostic value of the ureteral jet flow angle determined in color Doppler ultrasound as a noninvasive method in diagnosing VUR in children. Material-Method: In this prospective cohort study, 63 pediatric cases scheduled for VCUG were evaluated to confirm the diagnosis of VUR. Patients not having VUR on both sides included in the control group (n=32), while patients with VUR at least on one side formed the VUR group (n=31). VCUG and ureteral jet flow angle measurement with Doppler ultrasound were performed in all patients. Baseline descriptive data and ureteral jet flow angles were compared. Results: There was no significant difference between VUR and control groups in terms of age (p=0.287), gender (p=0.889), and bladder volume (p=0.211). Ureteral jet flow angle was higher in the VUR group on the right side (p=0.001) and on the left side (p<0.001) compared to the control group.
Conclusion: Ureteral jet flow angle can provide clues that can help diagnose VUR. However, more multicenter studies are needed to confirm this new sonographic marker’s validity.
