[contrast Enhanced Voiding Urosonography (cevus) in the Diagnosis of Vesicoureteral Reflux].

Vesicoureteral reflux (VUR) is one of the most common urinary tract anomalies in children and can be associated with reflux nephropathy (RN). Some patients with RN develop chronic kidney disease, hypertension and a small number of patients progress to end-stage renal disease. Early detection of children with these clinical characteristics should be the goal of clinical, biochemical, and radiological evaluation of patients presenting with prenatal hydronephrosis or febrile urinary tract infection. The goals of imaging procedure in general are to confirm the diagnosis suspected with a high degree of sensitivity and specificity, to aid treatment and allow prognosis. The diagnosis of vesicoureteric reflux (VUR) is a relatively straightforward and well-established procedure. There is increasing awareness of the risks of radiation exposure and invasivness of VUR investigation which can be unpleasant experience for both child and parents. Currently, contrast enhanced voiding urosonography (ceVUS) is a radiation free, highly sensitive imaging modality for vesicoureteral reflux (VUR) and urethral imaging in children. It employs ultrasound technology (contrast-specific software) in combination with commercially available second generation ultrasound contrast administered intravesically via a bladder catheter.
