Diagnosis of Stones
all patients should have a urine analyzed and cultured if indicated.
Microscopic hematuria or blood in the urine will often be present
helping to establish the proper diagnosis. Patients with associated
urinary tract infections will also exhibit white blood cells in
the urine or pyuria and bacteruria unless the calculus is completely
obstructing the infected side. Urinary crystals or crystalluria
if present will provide important information as to the etiology
of the renal stone. A serum chemistry survey and a complete blood
count (CBC) are also helpful in screening patient for renal disease,
malignancy or metabolic disorder.
