case_images: Native CT scan (a) at admission showing massive bilateral hydronephrosis and (b) at 3 months showing a complete regression of the hydronephrosis on the left side and a partial regression on the right side.

case_images: A native abdominal CT scan was performed showing bilateral hydro-uretero-nephrosis with massive dilatation of the upper ureters and of the renal pelvis (Figure 1(a)). A follow-up CT scan at 3 months showed a complete regression of the hydronephrosis on the left side and a partial regression on the right side (Figure 1(b)).
case_images: Retrograde pyelography showing bilateral hydro-uretero-nephrosis with a complete ureteral stenosis on the right and a partial ureteral stenosis on the left.

case_images: Bilateral ureteral catheterization using double J catheters was performed and the retrograde pyelography revealed that the bilateral hydronephrosis was due to a complete right ureteral stenosis and a partial stenosis on the left side (Figure 2).
case_images: Renal biopsy showing extracapillary crescentic glomerulonephritis involving almost all glomeruli (HE, 100x).
