Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief:

Urine analysis and urine culture should be done to look for any sign of urinary infection and serum creatinine and electrolytes should be done to check the kidney function.^[1]

Patients with horseshoe kidney may show following findings on laboratory tests. These include:

• Complete blood count (CBC):
  • Elevated WBC count may indicate the presence of infection.

• Elevated serum creatinine and BUN:
  • Suggestive of obstruction and an underlying kidney disease.
• Urinalysis and cultures: It may show red blood cells and white blood cells indicating hematuria and pyuria:
  • Hematuria is commonly caused by stones.
  • Pyuria indicates an evidence of infection.
  • Urinary cultures are helpful in identifying infection.
