Ureterabgangsstenose
Toddler with
hypercalcemia. Sagittal US of the left and right kidneys shows echogenic medullary pyramids bilaterally and mild right hydronephrosis.The diagnosis was nephrocalcinosis and a mild left ureteropelvic junction obstruction.
Toddler with
moderate to marked right hydronephrosis on ultrasound. AP image from the excretory phase of an intravenous pyelogram (above) shows a normal left renal collecting system and a markedly dilated right renal collecting system. No contrast was seen in the right ureter. AP image from a retrograde pyelogram (below) shows a markedly dilated right renal collecting system and a narrowing and tortuosity to the proximal right ureter.The diagnosis was right ureteropelvic junction obstruction due to a crossing vessel.

Radiografía
obtenida 60 minutos después de la administración del contraste EV. Dilatación pielocalicial severa, con calibre normal del uréter homolateral, sin evidencias de lesiones endoluminales, compatible con estenosis congénita de la unión pieloureteral. Obsérvese la impronta del cuerpo uterino sobre el sector lateral izquierdo del techo vesical.

School ager
with right flank pain and hematuria after falling off a table. Coronal (above left) and sagittal (above right) CT with contrast of the abdomen show an extremely dilated right renal collecting system surrounded by an extremely thin rim of renal cortex. The axial image (below) shows high density material within the medial aspect of the renal collecting system.The diagnosis was hemorrhage into a severe right ureteropelvic junction obstruction in a patient with renal trauma.
Teenager with
right flank pain when drinking large amounts of soda pop. AP image from the excretory phase of a vintage intravenous pyelogram (left) shows a normal left renal collecting system and left ureter and an extremely dilated right renal collecting system. Magnified views of the right ureteropelvic junction (right above and right below) show a sharp kink at the right ureteropelvic junction.The diagnosis was retrocaval ureter causing right ureteropelvic junction obstruction.

Newborn with
prenatal hydronephrosis in the left kidney4 hour delayed image from an IVP exam shows an extremely dilated left renal collecting system. The left ureter is not seen.The diagnosis was left sided ureteropelvic junction obstruction.

Infant with
bilateral prenatal hydronephrosis. Sagittal US of the right kidney (upper left) and left kidney (upper right) shows bilateral mild to moderate hydronephrosis. AP image from the excretory phase of an intravenous pyelogram shows bilateral moderately dilated renal collecting systems with normal appearing bilateral ureters.The diagnosis was bilateral ureteropelvic junction obstruction.
Teenager
playing ice hockey who was hit hard by another player into the boards. Axial CT without contrast of the abdomen (above) shows the unenhanced right kidney to have a low density dilated central collecting system and to be surrounded by a high density cresenteric fluid collection in the right perirenal space. Axial CT with contrast (below) better shows the low density dilated central collecting system and a decreased amount of enhancement in the right kidney when compared to the normal left kidney. The amount of enhancement in the right kidney is the same density as the right perirenal fluid collection.The diagnosis was a right perirenal hematoma in a patient with right ureteropelvic junction obstruction.
