What are the two plus signs for urine protein in physical examination

The discovery of two plus signs in urine protein during a physical examination usually indicates the possibility of kidney disease or other systemic diseases. The main causes of positive urinary protein are physiological factors, glomerulonephritis, diabetes nephropathy, hypertensive kidney damage, urinary system infection, etc.

1. Physiological factors

Physiological conditions such as intense exercise, fever, cold stimulation, or prolonged standing may lead to temporary proteinuria. This type of proteinuria is usually mild, and after removing the trigger, a follow-up urine routine can often restore normal levels. No special treatment is required. It is recommended to have a urine routine check 1-2 weeks after sufficient rest.

2. Glomerulonephritis

Primary or secondary glomerular disease leads to damage to the glomerular filtration barrier, manifested as persistent proteinuria. These patients may have symptoms such as hematuria, edema, and hypertension. Further evaluation such as 24-hour urine protein quantification, renal function testing, and renal ultrasound is needed, and standardized treatment may require the use of drugs such as prednisone acetate tablets and cyclophosphamide tablets.

3. diabetes Nephropathy

diabetes patients with long-term poor blood glucose control may have glomerulosclerosis, which is manifested as progressive proteinuria. Early visible microalbuminuria, later developed into massive proteinuria. Strict control of blood sugar and blood pressure is required, and measures such as valsartan capsules and atorvastatin calcium tablets can be used to protect kidney function.

4. Hypertension induced renal damage

Long term uncontrolled hypertension can cause renal arteriolar sclerosis, proteinuria, and renal dysfunction. These patients need to strictly control their blood pressure below 130/80mmHg, and can use antihypertensive drugs such as nifedipine sustained-release tablets and irbesartan tablets, while limiting sodium intake.

5. Urinary system infections

Urinary system infections such as cystitis and pyelonephritis may lead to transient proteinuria. Usually accompanied by symptoms such as frequent urination, urgency, and pain during urination, and an increase in white blood cells can be seen on urine routine examination. It is necessary to improve urine culture examination and use antibiotics such as levofloxacin tablets and cefuroxime dispersible tablets to treat infections. After discovering positive urine protein, it is recommended to avoid vigorous exercise and a high protein diet. It is suggested to have a follow-up morning urine test one week later. If the re examination result is still positive, it is necessary to seek medical attention promptly at the nephrology department and complete 24-hour urine protein quantification, renal function, renal ultrasound and other examinations to determine the cause. Normally, attention should be paid to monitoring blood pressure and blood sugar, maintaining a regular schedule, controlling salt intake to no more than 6 grams per day, and avoiding the use of drugs that may damage the kidneys.
