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 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.
