Answer

Hematuria may indicate renal cell carcinoma, tuberculosis, endocarditis, brucellosis, lymphoma, or periarteritis nodosa.

Asymptomatic pyuria and bacteriuria are common with advancing age and comorbidities, and these findings may offer little diagnostic direction. [12]

Normal urinalysis or urine culture results do not necessarily suggest or eliminate perinephric abscess. Approximately 30% of patients with perinephric abscess have normal urinalysis results, and up to 40% have sterile urine cultures. [13]
