Vesicoureteral reflux (cystourethrography)

Case contributed by Mauricio Humberto Pena Marquez


At 30 weeks of gestation, a morphological ultrasound revealed left ureteral dilation under prenatal control. An ultrasonography of the urinary tract was conducted at 2 months of age, showing left pyelocalyceal dilatation. Static renal scintigraphy showed a mild tubular deficit at 5 months of age.

Patient Data

Age: 6 months
Gender: Male

X-rays in the anteroposterior view with an image of the bladder opacified by the iodinated contrast medium after insertion of a urinary catheter. The left ureter and pyelocalyceal system were opacified, showing grade IV ureteral and pyelocalyceal dilation.

Case Discussion

Prenatal diagnosis is important for the diagnosis of fetal malformations of the urinary tract. For children born with these malformations, a morphological and functional diagnosis is important. Imaging exams, x-rays with contrast, ultrasound, and scintigraphy help in the diagnosis and its prognosis and treatment.
