The Harm Of Renal Needle Biopsy

Kidney puncture is a kind of traumatic examination, so the harm of doing kidney puncture is also a problem that people have been concerned about. What are the harms of doing kidney puncture? It doesn't matter. Today, let our experts introduce this problem in detail for you. I hope it can help you or your family. Blood in the urine. Hematuria is the most common complication of renal biopsy. About 80-90% of patients have microscopic hematuria after puncture, and the incidence of gross hematuria varies with the degree of puncture needle injury, accounting for about 5-50%. Generally, hematuria disappears spontaneously within 1~5 days without treatment and has no effect on the patient's kidney. Low back pain. After renal puncture, most patients have ipsilateral lumbago or discomfort, which disappears spontaneously in about 3-5 days, and a few patients last for a long time. The infection. Infection after puncture is mostly caused by lax sterility concept or bacterial diffusion of original kidney infection after puncture. Therefore, strict disinfection, correct operation method and reasonable selection of anti-vaccine drugs should be used to prevent infection during renal puncture. Blood pressure (hypotension). Persistent low blood pressure after puncture is usually caused by hemorrhage or hypovolemia in patients with nephrotic syndrome. What are the hazards of doing kidney puncture? Oliguria or anuria. The person that has little urine often has hypotension, the quantity of urine after correcting blood pressure increases, some cases are obstructed because of blood clot, visible kidney colic, after blood clot eduction, the symptom can remove. Tissue damage. Generally, renal puncture has slight damage to renal tissue, but due to the location of puncture site, it is tricky. Accurate, but also mistakenly into the liver, spleen, gallbladder or bowel, and cause complications. > What are the dangers of doing kidney puncture? Perirenal hematoma. Due to rich kidney blood supply and low perirenal pressure, it is easy to have blood exudation after puncture and form asymptomatic small hematoma, with an incidence of 0. About 5-1.5%, disappear after 3 months. (1) moderate and severe hypertension (blood pressure over 21.33/14.66kpa), due to easy bleeding or arteriovenous fistula after surgery, so the blood pressure must be controlled in the normal range before biopsy, otherwise it is not suitable for kidney biopsy. (2) Biopsy is not suitable for patients undergoing anticoagulant therapy because of difficulty in hemostasis. If a hemodialysis patient needs biopsy, a small amount of heparin or in vitro heparinization anticoagulation should be required during hemodialysis before and after biopsy, and renal biopsy can be performed 24 hours after hemodialysis. (3) For patients with chronic renal failure whose kidney has atrophied, not only because of the difficulty of puncture for renal atrophy, but also because of the high degree of fibrosis in renal tissue, it is no help for the diagnosis of primary nephropathy, and renal biopsy is of no value. (4) Renal biopsy should not be performed in patients with isolated horseshoe kidney or loss of renal function on the other side. In the event of serious complications from the biopsy requiring surgical removal, the patient could not survive without a kidney. (5) For active kidney infections such as pyelonephritis, renal tuberculosis, renal abscess or perirenal abscess, puncture is easy to cause inflammation diffusion, and biopsy should be carried out after inflammation is completely controlled. (6) The harm of renal puncture? Renal tumors cannot be punctured in a conventional manner; Otherwise, the tumor will spread. Renal hemangioma, renal cyst, polycystic kidney is not suitable for renal puncture. (7) Renal biopsy can only be performed after hydronephrosis is lifted. (8) Renal biopsy is not suitable for patients with heart failure, peripheral circulatory failure or very poor general condition. <(9) Patients with mental disorder cannot cooperate with the operation, and renal biopsy cannot be performed. (10) Percutaneous renal biopsy is generally not performed for patients with obesity or severe edema due to the difficulty in locating and puncture with B-ultrasound and low success rate. (11) The harm of renal puncture? For patients with high ascites, it is difficult to cooperate with the puncture in prone position, and if the puncture needle goes into the abdominal cavity, the ascites can leak out along the puncture path and even cause secondary infection. Therefore, renal puncture can be carried out only after ascites is eliminated. (12) Renal puncture should not be performed in the third trimester.
