The renal biopsy can cause complications

The renal biopsy can cause complications, renal biopsy is a way of checking the pathological diagnosis. However, renal biopsy can cause complications. Renal biopsy is an invasive examination, and its complications, trauma bleeding.
(1) hematuria, microscopic hematuria, the incidence is almost 100%, often disappear in 1-5 days without treatment. When the puncture needle into the renal calyx or pelvis within, gross hematuria, and its occurrence rate of 2% to 16%, most of them disappear in 1-3 days. Obvious gross hematuria or with a blood clot, usually in the the intravenous VitK1 or pituitrin can be alleviated, to pay attention to not use hemostatic agents, in order to avoid blockage of the urinary tract in favor of more serious consequences. Should encourage patients to drink more water, in order to ensure the patency of the urinary tract, patients with renal dysfunction should also pay attention to urinate, so as not to overcharge the drinking water in favor of heart failure. The vast majority of middle of the bleeding will not affect the changes in pulse, blood pressure and hemoglobin. Very few patients with severe bleeding should be fluids or blood transfusions to prevent the occurrence of shock. After full rehydration or blood transfusions to maintain blood pressure, you should consider underwent selective renal angiography, and decided to clear the site of bleeding, treatment with arterial embolization, surgical ligation of bleeding vessels, or partial nephrectomy.
(2) perirenal hematoma after renal biopsy of perirenal hematoma rate of 60% to 90%, generally small, with no clinical symptoms, self-absorbed more than 1 to 2 weeks. Large hematoma rate of 0.5% to 1.5%, mainly due to renal tear or wear Tai in vascular, especially arterial walls more than the day of puncture, but there are also report delayed until 9 to 60 days after puncture hematoma. Patients presented with abdominal pain, lumbar pain, puncture local tenderness or contralateral slightly bulging, puncture-side abdominal tenderness or rebound of disease, and in severe drop in blood pressure, hematocrit decreased, B ultrasound or X-ray examination can be further confirmed , and more generally allows bleeding remission. Bleeding, drop in blood pressure, surgical incision hemostasis or application of arteriography, embolization, such cases accounted for only 0.15%. Hematoma formation, should the use of antibiotics to prevent infection.
(3) low back pain kidney back pain in the puncture rate of 17% to 60%, usually caused by the hematoma, puncture injury and stay in bed too long walls than disappear within a week, only a handful of patients can be sustained for a long time.
(4) arteriovenous fistula incidence of 15% to 19%, most of them without clinical symptoms, clinical manifestations, only 0.1% to 0.5% of the cases of renal biopsy. The typical manifestation of severe hematuria and / or perirenal hematoma, refractory hypertension, progressive heart failure and lumbar abdominal vascular murmur.Arteriovenous fistula prone to hypertension, renal sclerosis and vasculitis, renal biopsy confirmed the need of renal angiography. The majority of patients with arteriovenous fistula healed spontaneously in 3 to 30 months without treatment, severe cases of renal artery branch embolization or surgical treatment.
(5) damage other organs is usually caused by the inappropriate choice of puncture site or the needle too deep walls can damage the liver, spleen, colon, ileum, duodenum, pancreas, gall bladder, adrenal gland, ureter, mesenteric artery, pleural cavity, severe cases should be treated surgically. Fortunately, this situation rarely found.
(6) infection rate of 0.2 percent to 2.6 percent, more lax because of aseptic measures, perirenal infection or associated with pyelonephritis caused by such as fever, severe back pain and rise in white blood cells should be used when antibiotics.
(7) death rate was 0 to 0.1%, due to severe bleeding, infection, organ damage or other complications Erzhi.
Kidney biopsy is an invasive examination, a variety of complications of renal biopsy in patients hospitalized for strict guardianship. Puncture the former should be fully prepared, should not at the same time on both sides of the kidney puncture in the piercing process, the number of the needle should be controlled in less than four times puncture after the close guardianship and take preventive measures in order to ensure patient safety.
