Presentation
Follow up on renal stones.
Patient Data
Horseshoe kidney with a right-sided double-J catheter in position.
Multiple stones are seen in the right middle and lower collecting system the largest measuring around 10 mm.
There is around 6 x 4 mm right distal ureteric stone along the course of the catheter.
Multiple stones are also seen in the left calyceal system the largest measuring around 10 mm.
There is moderate left-sided hydronephrosis and hydroureter without evidence of left ureteric stones.
Underfilled urinary bladder with Foley's catheter in satisfactory position and containing small gas pocket.
Mild prostatic enlargement is noted.
Double-J stents are seen bilaterally in a good position.
Multiple faint radiopaque stones are seen in the right paravertebral region, ranging in size between 2.5 and 8 mm.
These radio-opaque shadows are seen medial to renal shadow present stones in a horseshoe kidney.
Few faint stones are seen also on the left side, the largest measures about 9 mm.
Case Discussion
This case illustrates the typical appearance of horseshoe kidney on CT scan. KUB depicted radio-opaque shadows that do not follow the normal course of the urinary tract.
