All major complications occurred during weeks 23–28 of pregnancy, whereas no complications occurred in early (up to 21 weeks) or late (28 weeks to term) phases. After ultrasound localization of the kidneys, the overlying skin is prepped and draped in a sterile fashion, and a local anesthetic (we use 1% buffered lidocaine) is infiltrated to the depth of the kidney. Sonography after renal biopsy: Assessment of its role in 230 consecutive cases. Nephrology training programs and applicants: A very good match. Postural change during venous blood collection is a major source of bias in clinical chemistry testing. Although the complication rates of PRBs in solitary kidneys may not be higher, the consequence of a major complication can be more severe in these individuals. Although the presence of a >2-cm hematoma was associated with a greater absolute decrease in hemoglobin (6.9% versus 2.9% for <2 cm and 2.0% for no hematoma) and a hemoglobin decrease >10%, it was not associated higher rates of transfusion or intervention. A complete blood count is checked 6–8 hours after PRB, and a urine specimen is evaluated for gross hematuria and to confirm voiding before discharge. Safety of ultrasound-guided percutaneous renal biopsy-retrospective analysis of 1090 consecutive cases. Data on PRB complications with a solitary kidney are limited. Clinicopathologic correlations of renal pathology in Spain. A percutaneous kidney biopsy may be obtained for a number of reasons, including establishment of the exact diagnosis, as an aid to determine the nature of recommended therapy or to help decide when treatment is futile, and to ascertain the degree of active (ie, potentially reversible) and chronic (ie, irreversible) changes. Available at: Thank you for your help in sharing the high-quality science in CJASN. As an invasive diagnostic test, a kidney biopsy is  recommended if the following criteria are met: A kidney biopsy is required to make a diagnosis or provide information that guides treatment. Minor complications (hematomas not requiring transfusion or macrohematuria with loin pain) occurred in 5% of intragestational PRBs. Infection after kidney biopsy has been described in some case series (39), but if sterile technique is used and unless bowel perforation occurs, it is an extremely rare complication of PRB. Desmopressin acetate in percutaneous ultrasound-guided kidney biopsy: A randomized controlled trial. Patients with monoclonal gammopathies may require a kidney biopsy to document end organ damage from the offending paraprotein. Though complication rates are small, bleeding requiring surgery has been reported to occur in 1 in 1,000 kidney biopsies. In the case of Open Renal Biopsy it is performed in the operating theatre. In the meta-analysis by Corapi et al. Accreditation Council for Graduate Medical Education: ACGME Program Requirements for Graduate Medical Education in Nephrology (Internal Medicine). Most biopsy series exclude patients with coagulopathies and thrombocytopenia (usually <100×109/L). The kidney biopsy can be invaluable in assessing the extent of disease activity (e.g., inflammatory cell proliferation, crescent formation, and necrosis) and chronicity (e.g., sclerosis and fibrosis), which may help guide prognosis and therapy, as well as establishing renal involvement of systemic diseases, such as autoimmune and paraprotein disorders (2). Native kidney biopsies require examination by light microscopy, immunohistochemistry and electron microscopy. The data on the effect of high BP on PRB complication rates are not consistent, and a selection bias exists, because hypertension (usually defined as >140/90 mmHg) is an exclusion criteria in much of the biopsy literature. Lower complication rates have also been observed in series that exclude high-risk patients (38). A second study by Atwell et al. Safety and diagnostic yield of transjugular renal biopsy. One series found no difference in diagnostic yield or major complications in patients undergoing PRB (n=400) or TJKB (n=400; 303 of whom had bleeding disorders) (23). The data on the timing of complications after PRB are composed of prospective and retrospective case series with intra- and interstudy heterogeneity in operator, needles used, and definitions of complications. Renal biopsy in patients aged 80 years and older. Indications for a kidney biopsy in pregnancy include unexplained renal failure, symptomatic nephrotic syndrome, to help guide management of patients with lupus nephritis (62), and to make/exclude the diagnosis of preeclampsia. Perioperative management of antithrombotic therapy. It may be done in a procedure room, in a hospital bed, or in the radiology department. It is recommended that after a renal biopsy procedure, the patient remain in hospital for strict bed rest with frequent observations for a period ranging from 6 to 24 hours. These criteria have been increasingly met for the kidney biopsy since its initial description by Iversen and Brun in 1951, the introduction of immunofluorescence and electron microscopy, the linking of histologic findings with clinical outcomes, and the introduction of treatment regimens that could alter the disease course with acceptable side effect profiles (1). Characterizing chronic kidney disease (CKD) at all stages is an essential part of rational management and the renal biopsy plays a key role in defining the processes involved. Newer imaging techniques, such as CT fluoroscopy and fusion ultrasonography, may be useful in the future in certain patients undergoing PRB (21). Renal biopsy specimens as seen with a dissecting microscope. Another series found no increased risk of PRB complications for patients with monoclonal gammopathies versus controls (without monoclonal gammopathy; 4.1% versus 3.9%; P=0.88) (71). According to the AUA guideline, a renal mass biopsy should be considered when a mass is suspected to be hematologic, metastatic, inflammatory, or infectious (Clinical … This may be because of some PRBs being performed by nephrology trainees and more high-risk patients undergoing PRBs at large academic centers. Percutaneous native renal biopsy: Comparison of a 1.2-mm spring-driven system with a traditional 2-mm hand-driven system. Published online ahead of print. It should go without saying that a kidney biopsy should only be done by someone skillful in performing the procedure and when the tissue can be processed and interpreted by those with the skills necessary to do so (14). (63) found that, of 197 PRBs performed during pregnancy that also reported complications, four major events occurred (2%; two of which were associated with preterm delivery, and one of which may have been associated with fetal death) at a median time of 25 weeks gestation (range =23–26 weeks). A prospective randomized trial of three different sizes of core-cutting needle for renal transplant biopsy. A kidney biopsy is oftentimes not recommended in patients with isolated microscopic hematuria or low-grade proteinuria (<0.5–1.0 g/d) unless another indication, such as reduced kidney function, is present. A systematic narrative review. How long is strict bed rest necessary after renal biopsy? (13) conducted a systematic review and meta-analysis of all adult PRB studies from 1980 to 2011 (34 studies with 9474 biopsies meeting inclusion criteria) and found the rates of complications as listed in Table 2. The kidney biopsy is the gold standard in the diagnosis and management of many diseases. There remain no global guidelines available to the renal community on indications for this important diagnostic, prognostic, … Anticoagulants were also held according to protocol (16).
