Impression

This is a 3D volume-rendered CT urogram (excretory/delayed phase "uroscanner"), not a plain photograph of pathology — it's a reconstructed image showing the contrast-opacified urinary collecting system.
What is visible:
  • Both kidneys with normal, symmetric branching pyelocalyceal systems (the "antler-like" bright white pattern = contrast filling the calyces and renal pelvis) — no calyceal clubbing or caliectasis
  • Both ureters coursing down from the renal pelves to the bladder in a normal, non-dilated course, without any abrupt cut-off, filling defect, or focal dilation
  • A well-distended, homogeneously opacified urinary bladder, with a smooth outline and no filling defect
Assessment: Based on this single VR image, there is no obvious calculus (no filling defect casting a shadow), no hydronephrosis/hydroureter, no ureteral obstruction, and no gross duplication or fusion anomaly (kidneys are separate, normally positioned — not horseshoe). This looks like an essentially normal excretory-phase CT urogram.
Important caveats:
  • A VR (volume-rendered) 3D image is a post-processed reconstruction built for anatomic overview — small stones, subtle urothelial filling defects, or mild wall thickening are easily missed on VR alone and only reliably seen on the axial/coronal source images (non-contrast + excretory phase) and on maximum-intensity-projection (MIP) images.
  • The handwritten notes visible at the bottom of the photo (patient ID, dates, "TDM abdo-pelvien") suggest this is from a French-language radiology record — the actual reason for the scan (hematuria, stone workup, tumor surveillance, etc.) and the radiologist's report on the source slices would be needed to give a definitive diagnosis.
If you can share the clinical indication (e.g., flank pain, hematuria, known stone disease, post-op ureter check) or the axial/coronal slices, I can narrow this down further — right now, without a clear filling defect or dilation on the image you've shared, my read is "no acute abnormality demonstrated on this VR reconstruction; normal-appearing pyelocalyceal systems, ureters, and bladder."
