Patient Data

Age: Adult
Gender: Male

Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.

Horseshoe kidney with bilateral hydronephrosis:

  • the right kidney shows marked dilated renal pelvis and calyceal system with thinned out renal parenchyma (grade 4 hydronephrosis)
  • the left kidney shows moderate hydronephrosis with preserved renal parenchymal thickness (grade 2 hydronephrosis)

Case Discussion

Horseshoe kidney with bilateral hydronephrosis. The dilated pelvis bilaterally is suggestive of pelviureteric junction obstruction or upper ureteric strictures, evident on right kidney with subsequent right renal atrophy.

Horseshoe kidney remains asymptomatic until incidentally discovered or develop complications. One of the commonest complications is hydronephrosis, usually due to pelviureteric junction obstruction.
