Overview
Some patients with hydronephrosis may have elevated WBC count, serum creatinine, BUN, potassium levels and pyuria.
Laboratory Findings
Patients with hydronephrosis may show following findings on laboratory tests. These include:[1][2]
- Complete blood count (CBC):
- Elevated WBC count may indicate the presence of infection.
- Anemia
- Elevated serum creatinine
- Elevated BUN
- Elevated serum potassium levels (hyperkalemia)
- Urinalysis and cultures: It may show red blood cells and white blood cells indicating hematuria and pyuria.
- Hematuria is commonly caused by stones or due to tumors.
- Pyuria indicates an evidence of infection.
- Urinary cultures are helpful in identifying infection.
