Findings:

Radiopharmaceutical: 1.1 mCi Tc-99m MAG3 i.v. and 9 mg furosemide i.v.

Findings:

Renal scan: There is a horseshoe kidney with normal perfusion, uptake, and eventual clearance with no evidence of obstruction after diuretic administration.

Ultrasound: 2 distinct functioning kidneys, one on each side of the midline, connected at the lower poles by an isthmus of functioning renal parenchyma.

Diagnosis: Horseshoe kidney without obstruction.
General Discussion: This 9-month-old male has right-sided hydronephrosis and a horseshoe kidney discovered on a recent ultrasound examination.

Discussion: The estimated incidence of a horseshoe kidney is one in 500 live births. It is more common in males. Patients are predisposed to a higher incidence of disease including obstruction, stones and cancer. The most common associated finding is UPJ obstruction, seen in 35% of patients. The prevalence of stones ranges from 20-60%. Urinary stasis and stones predispose to infection.
