CLINICAL DIAGNOSTIC MANUAL
Asymptomatic proteinuria refers to the presence of proteins in the urine without evident clinical symptoms. This condition is often detected incidentally during routine examinations.
The presence of proteins in the urine can indicate renal dysfunction or benign and transient conditions. Careful evaluation and identification of the underlying cause are crucial to determining whether the proteinuria is a benign finding or indicative of more serious renal pathology.
Pathology | Clinical Symptoms and Signs | Suspected Diagnosis | Confirmatory Diagnosis |
|---|---|---|---|
Postural and orthostatic proteinuria | Proteinuria that appears when standing and disappears at rest, no other symptoms | Medical history, urine analysis in supine and standing positions | Fractionated proteinuria test (daytime and nighttime) |
Non-specific febrile illness | Fever, general malaise, symptoms of systemic infection, transient proteinuria | Medical history, physical examination, signs of infection | Resolution of proteinuria after recovery |
Urinary infection | Dysuria, urinary urgency, suprapubic pain, fever, proteinuria | Medical history, physical examination, signs of infection | Urine culture, urinalysis |
Glomerulonephritis | Hematuria, proteinuria, edema, hypertension | Medical history, physical examination, signs of renal insufficiency | Urinalysis, kidney biopsy |
Nephritis | Hematuria, proteinuria, edema, hypertension, history of systemic disease | Medical history, physical examination, signs of systemic disease | Urinalysis, kidney biopsy, specific studies for underlying disease |
Nephrotic syndrome | Massive proteinuria, edema, hypoalbuminemia, hyperlipidemia | Medical history, physical examination, signs of nephrotic syndrome | Urinalysis, lipid profile, kidney biopsy |
