The CT urography demonstrates:
- right hydronephrosis with calyceal rupture and extravasation of contrast medium in the renal parenchyma
- perinephric fat stranding with thickening of the adjacent peritoneal reflections
- the upper end of the double J stent is lying outside the renal cavities through a perforation of the pelviureteric junction with mild extraluminal periureteric contrast at the level of the right transverse process of L3.
Normal appearance of the left kidney and urinary bladder.
Case Discussion
The most common complications of ureteric stents include 1,2:
- urinary tract infections
- migration
- failure to insert/blockage
- encrustation
- stent fracture
- renal parenchymal perforations are rarely reported in the literature
