ICD-10: N02.5

ICD-10 code N02.5 refers to "Recurrent and persistent hematuria with diffuse mesangiocapillary glomerulonephritis." This classification is part of the broader category of hematuria, which is the presence of blood in urine, and it specifically indicates a chronic condition associated with a particular type of kidney disease.

Clinical Description

Hematuria

Hematuria can be classified as either gross (visible to the naked eye) or microscopic (detected only through laboratory testing). In the case of recurrent and persistent hematuria, patients experience ongoing episodes of blood in their urine, which can be indicative of underlying renal pathology.

Mesangiocapillary Glomerulonephritis

Diffuse mesangiocapillary glomerulonephritis, also known as membranoproliferative glomerulonephritis (MPGN), is characterized by the proliferation of mesangial cells and an increase in the number of capillary loops in the glomeruli. This condition can lead to significant kidney damage and is often associated with various systemic diseases, including infections, autoimmune disorders, and certain types of vasculitis.

Symptoms and Diagnosis

Patients with N02.5 may present with:
- Hematuria: Blood in urine, which may be intermittent or persistent.
- Proteinuria: Presence of excess protein in urine, which can indicate kidney damage.
- Edema: Swelling due to fluid retention, often seen in kidney disease.
- Hypertension: High blood pressure, which can be a consequence of kidney dysfunction.

Diagnosis typically involves:
- Urinalysis: To confirm the presence of blood and protein in the urine.
- Serum tests: To assess kidney function and check for underlying conditions.
- Imaging studies: Such as ultrasound or CT scans to evaluate kidney structure.
- Kidney biopsy: In some cases, to confirm the diagnosis of mesangiocapillary glomerulonephritis and to determine the underlying cause.

Treatment and Management

Management of recurrent and persistent hematuria with diffuse mesangiocapillary glomerulonephritis focuses on treating the underlying cause and managing symptoms. Treatment options may include:
- Immunosuppressive therapy: Such as corticosteroids or other immunosuppressants, particularly if the condition is autoimmune in nature.
- Control of blood pressure: Using antihypertensive medications to manage hypertension.
