When Lao Wang next door urinated recently, he found that there was a lot of foam in the urinal, and it still lasted for a long time. I always feel weak all over, and my feet are swollen, making a hole when I press them. After going to the hospital and undergoing a lot of blood and urine tests, the doctor said that Lao Wang was suffering from "nephrotic syndrome", and that it was necessary to take a kidney biopsy and take some kidney tissue out for testing to clarify Lao Wang's condition.
Lao Wang was startled when he heard that the kidney is such an important thing. How can I take it casually! "And I've had so many blood tests and urine tests, how can I still be confused about my condition? I have to take out some kidneys to know the situation. Is there anything fishy in this?"?
After hesitating, Lao Wang still told the doctor about his concerns, and let's see what the doctor said.
What is a renal puncture
Kidney puncture is like an injection. The slightly different thing is that under the guidance of B-ultrasound, this needle is slightly thicker and longer than ordinary needles. It is quickly inserted from the back, all the way to the surface of the kidney, and then quickly pulled out. This process only takes a few seconds and requires local anesthesia in advance, with no or only slight pain.
After the needle for renal puncture is pulled out, a centimeter sized kidney tissue will be taken from the needle, and doctors will use this "extracted kidney" to make a diagnosis under a microscope.
"With blood and urine tests, why do I have to" take "my kidney?"
If you compare your illness to a house, blood and urine tests can only let the doctor know that you have a house. But whether this house is a one room one hall or two rooms one hall, you can only see it when you enter the house.
Kidney puncture is such a "walk into the house" examination. A clear understanding of the specific structure of the "house" can lead to a detailed treatment plan for the condition.
"If you do not perform renal biopsy and do not understand the specific situation inside the" house ", the treatment of the disease is like feeling like a blind person touching an elephant, delaying the illness.".
Who needs a kidney puncture
When urinating, the foam increases, the urine color turns red, and the lower limbs or face has edema of unknown cause. The doctor diagnosed the patient as "proteinuria", "hematuria", "nephritis", and "nephrotic syndrome";
Renal failure that cannot be explained by routine examination;
People who were diagnosed with basic diseases such as "hepatitis B", "systemic lupus erythematosus", "diabetes" and "hypertension" in the past have recently developed proteinuria or hematuria, or kidney function has deteriorated;
People who have undergone renal puncture in the past and have had poor therapeutic effects after targeted treatment;
Patients with renal transplantation who experience significant decline in transplanted kidney function due to unclear causes or poor therapeutic effectiveness.
Who should not do renal puncture as much as possible
Patients with only one kidney due to various reasons;
Patients with a significant bleeding tendency (after bleeding, blood is not easy to coagulate);
Patients with mental illness who cannot cooperate with renal puncture;
Patients with renal shrinkage, polycystic kidney, cavernous kidney, and renal hemangioma were found by B-ultrasound.
Who is temporarily not suitable for renal puncture
Patients whose blood pressure is still higher than 160/90mmHg after drug treatment;
Excessive obesity, massive hydrothorax and ascites, inability to roll over;
Patients with renal positional abnormalities, renal tumors, or infections in or around the kidneys;
The overall condition is serious, and the doctor does not recommend kidney puncture based on specific evaluation.
Of course, whether the final patient is suitable for puncture must be specifically determined by the clinician based on the needs of diagnosis and treatment.
What should be paid attention to during renal puncture
Before inspection
Relax, eat, sleep. Do not eat foods that are prone to constipation or bloating, such as beans, sweet potatoes, potatoes, milk, etc.
Practice kidney puncture posture and suffocation. Kidney puncture requires the patient to be in a prone position, and if necessary, a pillow with a height of about 10 cm will be placed in the abdomen. Practice holding your breath in this position for about 10-20 seconds.
Practice urinating and defecating in a prone position in bed. To prevent bleeding, the patient is required to maintain an absolute lying position for at least 6-8 hours after renal puncture, and must not get out of bed within 24 hours. The problem of urination and defecation can only be solved by lying in bed. Don't be shy!
After inspection
Lie flat in bed for 24 hours, and do not use force to move;
Observe heart rate and blood pressure. If you notice a decrease in blood pressure or a rapid increase in heart rate, immediately consult a doctor;
Drink more water and urinate more. Observe the color of urine. If you notice dark or red urine color, immediately consult a doctor;
"After puncture, severe pain and soreness appear in the lumbar region of the puncture side. Please consult a doctor immediately.".
How to Treat the Report of Renal Puncture Biopsy
Because kidney disease is a long-term chronic disease, it is necessary for patients to properly keep their own renal biopsy reports, providing important reference value for future diagnosis and treatment.
After the doctor said this, Lao Wang took a long breath and his small heart thumped back from his throat. The doctor looked at Lao Wang's awkward appearance and smiled and said, "Kidney puncture is not scary at all, and the little kidney tissue you take can't buy the latest iPhone phone. It's the right approach to pay attention to your physical changes and rationally view the disease and examination."
