  • Figure 1
    Longitudinal US of the right kidney

    Longitudinal US of the right kidney shows hyperechoic foci in calices and pelvis with acoustic shadowing, not mobile in prone position, that correspond to encrustation.

     
    Area of Interest: Abdomen; Kidney; Urinary Tract / Bladder; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Calcifications / Calculi; Infection; Transplantation;
     
     
  • Figure 2
    Transversal US of the right kidney

    Transversal US of the right kidney shows urothelial calcifications involving the renal pelvis, hydronephrosis (renal pelvis of 18.9 mm) and hyperechogenic material in the pelvicalyceal cavities. Staghorn calculus was...

    Unenhanced CT images of the abdomen and pelvis
     

    Unenhanced CT images of the abdomen and pelvis. Axial image through the kidneys show thin and irregular urothelial calcifications.

     
    Area of Interest: Abdomen; Kidney; Urinary Tract / Bladder; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Calcifications / Calculi; Infection;

    Note the staghorn calculus observed in US images.

  • Figure 4
    Coronal reconstructed image through the kidneys

    Coronal reconstructed image through the kidneys exemplify the urothelial thin calcifications.

     
    Area of Interest: Abdomen; Kidney; Urinary Tract / Bladder; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Calcifications / Calculi; Infection;
     
     
  • Figure 5
    Sagittal reconstructed image of the right urether

    Sagittal reconstructed image of the right urether shows thickening of the wall with encrusted calcifications.

     
    Area of Interest: Abdomen; Kidney; Urinary Tract / Bladder; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Calcifications / Calculi; Infection;
     
     
  • Figure 6
    Coronal reconstructed image through the urinary bladder

    Coronal reconstructed image shows thin calcifications in bladder urothelium. Encrustation is thin, irregular, and superficial. Image is more sugestive of encrustation than of staghorn calculi.

Transversal US of the right kidney shows urothelial calcifications involving the renal pelvis, hydronephrosis (renal pelvis of 18.9 mm) and hyperechogenic material in the pelvicalyceal cavities. Staghorn calculus was observed in the pyelo-uretheral junction.
