But we all know that, in fact, there is a certain renal biopsy traumatic, so many patients "do renal biopsy really good" are very concerned about this issue.        
    In fact, do renal biopsy in certain cases still effective and can help patients with a definite diagnosis. Kidney disease, especially renal disease diagnosis is more complex, the same clinical manifestations can come from different pathological types, but also showed the same histological type variety of clinical manifestations, the lack of inter-fixing law. Can correct pathological diagnosis is very meaningful. But can lead to renal biopsy in patients below are some of the symptoms or complications:
　　(1) hematuria: hematuria incidence of almost 100%, often disappeared after 1-5 days without treatment. When very few patients severe bleeding, blood transfusion or infusion should monitor blood pressure and hemoglobin. If after the rescue is still unable to maintain blood pressure, should be considered selective renal artery angiography to clear the bleeding site, and decided to use arterial embolization, or take surgery.
　　(2) low back pain: incidence of about 17-60%, within more than a week away.
　　(3) damage to other organs: usually caused by improper or needle puncture too deep organ damage, severe cases require surgery.
　　(4) perirenal hematoma: perirenal hematoma incidence of about 60-90%, generally small, no clinical symptoms, and more absorbed in 1-2 weeks. Large hematoma rare, mostly due to renal vascular Tai tear or wear, especially caused by artery puncture occurred the same day more, manifested as abdominal pain, back pain, tenderness, or compared with the contralateral puncture site slightly bulging, puncture the side abdominal tenderness, rebound pain, severe drop in blood pressure, hematocrit decreased, the line B-or X-ray examination can be further confirmed, in general, conservative treatment, if bleeding can be treated surgically.
　　(5) The death: incidence of 0-0.1%, due to severe bleeding, infection, organ damage or other complications arise death.
　　(6) arteriovenous fistula: the incidence of 15-19%, the majority of patients have no symptoms. Typical performance for severe hematuria and / or perirenal hematoma, refractory hypertension, progressive heart failure, abdominal vascular murmur waist. Diagnosis was confirmed by renal angiography, most self-heal in 3-30 months, serious and timely surgery.

　　(7) infection: the infection rate is low, more lax because of aseptic measures, perirenal existing infection caused by or associated with pyelonephritis, such as fever, severe back pain, leukocytosis required antibiotics.
