The study by Whittier and Korbet shows that more than 90% of major complications are identified within the first 24 hours. Most of the contraindications of percutaneous renal biopsies are relative. The percutaneous renal biopsy under ultrasound control in real time with an automatic pistol has thus become the technique of reference. Usually the patient is placed in a supine position on a hard plane and on a rolled pillow serving as a block compressing the abdomen and fixing the kidney. There are two exceptions to the renal biopsy rule for nephrotic syndrome: • children between 1 and the age of puberty, in whom we can first retain the diagnosis of glomerulopathy with “minimal glomerular lesions” (LGM), in the absence of atypical elements, such as the decrease in C3, l the existence of hematuria and / or renal insufficiency. Hogan JJ, Mocanu M, Berns JS. Clinical Transplantation. In this case the GFR should be remeasured in a month, and if the GFR remains low, a renal biopsy is required. 5(6):1354-60. The inability to rule out the factors favoring bleeding intervenes in the choice of the renal biopsy technique. The study in immunofluorescence is oriented towards an etiological research that distinguishes a rheumatoid purpura, an endocarditis with post-infectious glomerulonephritis, and especially a Goodpasture syndrome. The use of 14 gauge needles is preferable for clean kidneys. No other clinical or radiological element, nor the systematic ultrasound monitoring immediately after the renal biopsy, nor the initial modification of the hematocrit distinguishes patients at risk of severe complications. The “horseshoe” kidney was considered as a contraindication to the renal biopsy without being able to determine whether this was due to positional abnormalities or the unique character of the kidney. The transvenous biopsy technique uses the native vessels as a way of access to the renal parenchyma: internal jugular vein → vena cava → right renal vein. Significant hematuria may be responsible for ureteral or bladder obstruction. The indication of renal biopsy is reinforced by the clinical context, as for example during rheumatoid arthritis with proteinuria. Contraindications to Renal Biopsy bleeding diathesis is the major contraindication . Two major modifications have significantly increased the efficiency and especially the safety of the technique: the real-time guidance and the use of the automatic gun. “The College of American Pathologists” and “The American Society of Clinical Pathologists” do not recognize bleeding time as a routine preoperative test without significant prior bleeding. Late biopsies also provide essential information to differentiate acute cellular rejection or antibody-mediated rejection, from nephrotoxicity to calcineurin inhibitors or viral nephropathy (BK virus nephropathy), or lymphoproliferation, or d a graft injury by the initial kidney disease, etc. 2016 Feb 5. However, major complications are reported in 6-7% of all biopsies. More than 90% of major complications and 89% of all complications occur within 24 hours of renal biopsy. The majority of arteriovenous fistulas are asymptomatic and progress favorably, making screening routine useless. 1998 Nov. 9(11):2129-34. The only absolute contraindications are the lack of consent and the inability of the patient to cooperate during the procedure. This website also contains material copyrighted by 3rd parties. If the disorder cannot be corrected and the biopsy is indispensable .Alternative approaches can be used, such as open biopsy, laparoscopic biopsy or transvenous (usually transjugular) biopsy . J Nephrol. The use of the automatic gun also showed its superiority compared to the manual technique “on the needle”. Eric M Ghiraldi New York College of Osteopathic MedicineDisclosure: Nothing to disclose. The endovenous pathway can be proposed as an alternative biopsy of a single right kidney. The renal biopsy during the ARI is indicated in case of: The presence of haematuria and pathological albuminuria accompanying the IRA leads to glomerular involvement, such as vasculitis. • Perinatal hematoma occurs in less than 6% of prospectively evaluated renal biopsies. The transvenous biopsy technique uses the native vessels as a way of access to the renal parenchyma: internal jugular vein. TAP abnormalities combined with a history of bleeding make it possible to detect the existence of an abnormality of hemostasis in almost all cases. Treatment with DDAVP, under the control of TAP, may be useful in these patients. In this case, it may reveal lesions justifying specific treatment (extracapillary proliferation, cholesterol emboli, interstitial nephropathy). A very large and recent pre-surgery study of 5,649 unselected patients showed that TAP had a positive predictive bleeding value of 82% and a negative predictive value of 93%. J Ultrasound Med. Absolute contraindications to percutaneous renal biopsy have historically included uncontrolled severe hypertension, inability to cooperate with biopsy, solitary kidney, and uncontrollable bleeding diathesis. The majority of the hematomas are asymptomatic and small. Proteinuria is a marker but also a prognostic factor for renal disease. Factors Contributing to the Success of Ultrasound-Guided Native Renal Biopsy. Bienvenue ! Loupy A, Haas M, Solez K, et al. In native kidneys, renal biopsy is used to identify various renal diseases especially glomerular or interstitial pathologies. Of the data routinely collected for potential predictors of postbiopsy bleeding complications, only gender, age, and baseline partial thromboplastin time show a significant predictive value. The only absolute contraindications are the lack of consent and the inability of the patient to cooperate during the procedure. Currently, two techniques are used: the transjugular PBR using a modified Colapinto aspiration system and, more recently, the “Quick-core” cutting system. Resting in the supine position is recommended in the first 24 hours. The theoretical advantages of this technique are: • drainage of bleeding is mainly through the vein, thus limiting extravascular extravasation; • the needle travels away from large vessels; The main disadvantage is the small size of the predominantly medullary samples, and the difficulty of the techniques, which reduces the diagnostic yield of the technique. [Full Text]. Renal biopsy may also be useful from a diagnostic and therapeutic point of view in patients with non-nephrotic flow proteinuria, hematuria or chronic kidney disease. Four groups of patients benefit from the findings of renal biopsy: those with a nephrotic syndrome, those with a renal disease in a context of systemic disorder, those with acute renal failure and those with a renal transplant. The latter has a smaller diameter allowing deeper catheterization, without excessive fragmentation of the tissues. The use of the automatic gun also showed its superiority compared to the manual technique “on the needle”. The feasibility of the technique has been demonstrated by Mal et al. 2017 Jan. 17 (1):28-41. [Medline]. After removal of the urological causes of haematuria, the most probable diagnoses remain nephropathy with fine basement membranes and immunoglobulin (Ig) A nephropathy. Relative contraindications are hydronephrosis, pyelonephritis, renal abscess, uncontrolled hypertension (upper limit 150 mm Hg systolic and 95 diastolic), anomalies of renal shape and position (horseshoe kidney), large renal tumors, and small kidneys (increased bleeding risk). 15(3):258-61. In this context, an additional precaution is required: selective embolization in case of extravasation of contrast medium after capsular perforation. Rose, MD, Burton, and Theodore Post MD. This is especially true with regards to acute kidney injury (AKI). Their existence justifies the current practice of 24-hour rest in bed, contributing to the decrease in the incidence of clinically significant hematomas. Exceptionally, they can lead to persistent macroscopic hematuria, post-traumatic arterial hypertension (hypertension), or even degradation of renal function, thus imposing selective arterial embolization. Thus, the recommended renal postbiopsy period is 24 hours. [Medline]. Ultrasound can determine the depth of the location of the kidneys and diagnoses such contraindications to nephrobiopsy, as polycystic … Renal biopsy is an essential step in the study of kidney disease. CTRL + SPACE for auto-complete. Medical Actu – Actualités Médicales Quotidienne – Actualité Santé, Renal biopsy: contraindications, complications. It is reserved for patients with contraindications to conventional percutaneous renal biopsy because the fragments taken are small, with a modified architecture. The journals on the subject date from before the use of ultrasound guidance. 2015 Mar. Uncontrollable severe hypertension. The theoretical advantages of this technique are: The main disadvantage is the small size of the predominantly medullary samples, and the difficulty of the techniques, which reduces the diagnostic yield of the technique. 2015 Dec. 84 (12):311-22. Exceptionally, the obstacle on a single kidney can be the cause of acute renal failure. Semin Intervent Radiol. The presence of macroalbuminuria or microalbuminuria in patients with a diagnosis of diabetic nephropathy in the absence of renal biopsy in patients with diabetes mellitus (type I) at least 10 years old or with diabetic retinopathy Guidelines KDOQI. Immediate ultrasound monitoring of renal postbiopsy has no predictive value on the development of hematomas. Resting in the supine position is recommended in the first 24 hours. Ther Umsch. Importance of allograft biopsy in renal transplant recipients: correlation between clinical and histological diagnosis. They require general anesthesia, the risk of which must be taken into account when choosing the technique. Thus, it is important to establish the diagnosis of nephropathies in patients with proteinuria> 1.5 g / 24 hours, although sometimes the therapeutic implications remain modest. The indication of renal biopsy is reinforced by the clinical context, as for example during rheumatoid arthritis with proteinuria. A renal biopsy is a procedure used to obtain a segment of renal tissue, usually through a needle or another surgical instrument. Historical contraindications for PRB such as bleeding diathesis, morbid obesity and solitary kidney have been called into question in the literature. The empirical treatment with desmopressin (DDAVP) of all the patients before the biopsy brings a better cost-effectiveness. 31(6 Suppl 1):S15-8. These complications become exceptional with the real-time feedback technique. The risks of renal biopsy … TAP abnormalities combined with a history of bleeding make it possible to detect the existence of an abnormality of hemostasis in almost all cases. It has the advantage of simplicity and reduced cost due to a short hospital stay of 24 to 48 hours. 1994 Jan. 57(2):208-11. Both techniques have a low risk of complications requiring nephrectomy. However, a urologist can also perform a … Un mot de passe vous sera envoyé par email. When the extrarenal signs are not very evocative, the renal biopsy can reveal specific lesions of necrotizing angiitis. increasing proteinuria, elevated blood pressure and kidney failure ). The main complication is bleeding, with a life-threatening complication rate of 0.1%. Chapter 2B: Renin-angiotensin system." In other series using the same aspiration technique, the rate of symptomatic complications is greater up to 18% of patients, most likely influenced by patient selection and the local policy of contraindication of percutaneous biopsies. The gun may be disposable or use disposable needles. Renal biopsy is an essential step in the study of kidney disease. If you log out, you will be required to enter your username and password the next time you visit. In limited circumstances, alternative methods for kidney biopsy may be indicated. Clinical Transplantation. Connectez-vous à votre compte : © 2020 Medica-Actu.com. Absolute contraindications to renal biopsy include the following: Uncorrectable bleeding diathesis. Absolute contraindications to renal biopsy include the following: The following are relative contraindications to renal biopsy: Anatomic abnormalities of the kidney which may increase risk. [Medline]. Transvenous or transjugular renal biopsy, requiring retrograde access through the venous system, was recently proposed as an alternative for patients with contraindications for percutaneous biopsy. ESNT-CNE 1st Course Cairo Sept 10-14, 2012 For more than 50 years, renal biopsy has been an important diagnostic procedure in modern nephrology. This statement is not based on any studies. Renal biopsy can provide important information, especially if kidney failure accelerates. Usually the patient is placed in a supine position on a hard plane and on a rolled pillow serving as a block compressing the abdomen and fixing the kidney. Kitterer D, Gürzing K, Segerer S, Alscher MD, Amann K, Braun N, et al. The indication of renal biopsy in this situation remains controversial. Hypertension is classically recognized as a risk factor for bleeding. Patients with advanced chronic kidney disease (GFR <40 ml / min / 1.73m. Even in the absence of specific studies evaluating TAP as a predictor of renal biopsy bleeding, these results justify its use as a screening test before renal biopsy. Although their incidence and spectra have not been altered over time, we note a reduction in severe complications and an increase in their management by endovascular gestures. Patients undergoing an elective biopsy with uncontrolled hypertension who cannot be managed with intravenous or oral medications should have the … Uncontrolled severe hypertension; Hemorrhagic diathesis; Solitary kidney; Large and multiple renal cysts; Small, shrunken kidneys; Urinary tract obstruction; Complications. Diagnostic intake of renal biopsies is indisputable for four indications: nephrotic syndrome, systemic diseases with renal involvement, acute renal failure (ARI) and renal graft dysfunction. In most cases, it merely requires medical supervision and an abundance of drinks. [Medline]. It allows to confirm the diagnosis of rejection and also to specify its pathological mechanism (acute rejection mediated by antibody or acute rejection cellular). A recent study identified as factors associated with haemorrhagic complications of ultrasound-guided percutaneous renal biopsies: • age: the risk is higher for the two extremes of age (<20 years and> 70 years), whatever the histological diagnosis; • part-time thromboplastin: the risk of bleeding is increased with each 10% increase in the part-time thromboplastin. Renal biopsy may also be useful at a distance from the initiation of treatment to assess the therapeutic response and thus to judge the desirability of continuing immunosuppressive therapy. No correlation was found between their volume and the different predictors of bleeding. The quality of the samples by the 18 gauge needles is insufficient with poor diagnostic yield. For guardians and minors, the consent of the guardian or parents must be required before the biopsy. Rush D. Protocol transplant biopsies: an underutilized tool in kidney transplantation. Available at http://www.nlm.nih.gov/medlineplus/ency/article/003907.htm. Arteriovenous fistula; Infection • adults with diabetes, with a long history of diabetes, with a progressive increase in the proteinuria flow, up to the nephrotic flow. The simplicity of the technical gesture combined with the wealth of diagnostic and prognostic information makes the biopsy indispensable in the monitoring of kidney transplants. Teams have shown a short- and long-term benefit of routine biopsies of the renal graft. Accessed: June 18, 2012. If AA amyloidosis is detected, anti-inflammatory therapy should be intensified, whereas extramembrane glomerulopathy (GEM) should stop gold salts or penicillamine. The diagnosis of patients with ARI is mainly focused on acute tubular necrosis, particularly in a clinical context suggestive of renal hypoperfusion. Imaging-guided percutaneous renal biopsy has evolved to become a safe, minimally invasive technique to sample renal parenchyma for the evaluation of malignancy or diffuse renal disease. The journals on the subject date from before the use of ultrasound guidance. In this study, neither hemoglobin, renal insufficiency, nor bleeding time were predictive of hemorrhagic complications. The technical improvements made in recent decades have transformed the renal biopsy into a safe and informative technique, allowing it to play a central role in the nephrological diagnostic approach. The Native Kidney Biopsy: Update and Evidence for Best Practice. Journal of the American Society of Nephrology 5.6 Dec 1994. However, most necrotizing angels with renal involvement are considered primitive: Wegener’s granulomatosis, microscopic polyangiitis, Churg syndrome and Strauss syndrome, closely associated with anticytoplasmic antibodies to polymorphonuclear cells (ANCA). Some patients with non-nephrotic proteinuria, hematuria and chronic renal failure may also benefit from the procedure. Renal biopsy is indicated in cases of absence of diabetic retinopathy, accelerated degradation of GFR, sudden increase in proteinuria, presence of active urinary sediment or signs of other systemic diseases when other etiologies are to be considered . Analysis of this tissue is then used in the diagnosis of an underlying renal condition. Exceptionally, the obstacle on a single kidney can be the cause of acute renal failure. The single kidney is a contra-indication “relative” to the percutaneous biopsy. 91 (9):817-20. [Full Text]. The exception is a child recovering from an acute glomerulonephritis (e.g., postinfectious glomerulonephritis). More than 95% of arteriovenous fistulae close spontaneously within 2 years, although persistence of haematuria has been reported 30 years after renal biopsy. Renal biopsy continues to be a pivotal tool and frequently indispensable diagnostic procedure in the clinical assessment of proteinuria and or unexplained renal disease. The existence of persistent thrombocytopenia, the use of antiaggregants in patients with active coronary stents or anticoagulants in patients with extensive venous thrombosis or pulmonary embolism justify the choice of the transvenous route. Historical contraindications for PRB such as bleeding diathesis, morbid obesity and solitary kidney have been called into question in the literature. [Medline]. It was 13% in a recent series of 750 renal biopsies performed over 20 years, during which the diagnosis of complications was mainly clinical (hematuria, pain, hypotension, hematocrit reduction) and 34% when ultrasound kidney postbiopsy research was systematic. The local pain in the end of the effect of local anesthesia is commonplace and most often does not require treatment.Sometimes the pain may be more severe, requiring even opiates, especially in cases of large perirenal hematoma or renal colic due to ureteral obstruction with blood clots. The latter has a smaller diameter allowing deeper catheterization, without excessive fragmentation of the tissues. • Arteriovenous fistula was reported in 10.8% of the kidney biopsies in the series with systematic screening by post-echocardiography, with a significant difference between the native kidneys (4.1%) and the biopsied transplants (16.9%). Laparoscopic renal biopsy. Kriegshauser JS, Patel MD, Young SW, Chen F, Eversman WG, Chang YH, et al. The persistence of this relatively high incidence over time is explained at least in part by the widening of the contraindications to the realization of renal biopsies in patients at risk, such as patients with a significant drop in filtration rate glomerular (GFR) estimate. Recent studies report a success rate (diagnostic biopsies) of more than 99% and less than 0.1% of vital complications. Their use is not accompanied by an increase in hemorrhagic complications compared to 16 gauge needles. Immunological marking and molecular biology studies have helped to clarify the clinical and histological individualization of kidney disease and have opened up many possibilities for their pathogenic understanding. Physical activity should be moderate for 8 to 15 days following the biopsy. For guardians and minors, the consent of the guardian or parents must be required before the biopsy. The endovenous pathway can be proposed as an alternative biopsy of a single right kidney. The incidence of haemorrhagic complications is evaluated differently in the literature, depending on the techniques used for their diagnosis. The persistence of this relatively high incidence over time is explained at least in part by the widening of the contraindications to the realization of renal biopsies in patients at risk, such as patients with a significant drop in filtration rate glomerular (GFR) estimate. Nevertheless, in the presence of chronic renal failure with small kidneys, renal biopsy is dangerous. 1 Mar 2012. 29(3):268-76. Several studies have shown an acceleration of the degradation of renal function in relation to the flow of proteinuria. in 1990. The gun may be disposable or use disposable needles. They may be encountered in systemic diseases such as SLE, rheumatoid arthritis and cryoglobulinemias; they can occur in the course of bacterial or viral infection, after taking a toxic or in the course of certain malignant diseases.However, most necrotizing angels with renal involvement are considered primitive: Wegener’s granulomatosis, microscopic polyangiitis, Churg syndrome and Strauss syndrome, closely associated with anticytoplasmic antibodies to polymorphonuclear cells (ANCA). A good visualization of the vascularization of this kidney is to be proposed. The modified Colapinto system has been used successfully by several groups in France and the Czech Republic. Proteinuria is a marker but also a prognostic factor for renal disease. More than 90% of major complications and 89% of all complications occur within 24 hours of renal biopsy. Several studies have shown an acceleration of the degradation of renal function in relation to the flow of proteinuria. [Medline]. In this case, it may reveal lesions justifying specific treatment (extracapillary proliferation, cholesterol emboli, interstitial nephropathy). Indications and results of renal biopsy in children: a 10-year review from a single center in Serbia. Percutaneous renal biopsy. The risk potentially incurred by the reduction of observation time does not seem justified. These are clinically significant complications requiring therapeutic (radiological, surgical or transfusion of red blood cells) or acute renal failure, obstruction, septicemia or death. Choi BS, Shin MJ, Shin SJ, et al. The study in immunofluorescence is oriented towards an etiological research that distinguishes a rheumatoid purpura, an endocarditis with post-infectious glomerulonephritis, and especially a Goodpasture syndrome. Am J Transplant. It was 13% in a recent series of 750 renal biopsies performed over 20 years, during which the diagnosis of complications was mainly clinical (hematuria, pain, hypotension, hematocrit reduction) and 34% when ultrasound kidney postbiopsy research was systematic. Korbet SM. Since the 1950s, this technique has been constantly simplified and improved. Indeed, the use of bleeding time as a screening test before renal biopsy remains highly controversial. 2002. In addition, ultrasonography can detect focal renal lesions (e.g., masses, infiltrative areas) to allow selection of the proper kidney and region to be biopsied. Two surgical techniques are described: “open-pit” renal biopsy and laparoscopy. Lanna Cheuck, DO is a member of the following medical societies: American Osteopathic Association, American Urological Association, Endourological Society, Society of Women in UrologyDisclosure: Nothing to disclose. Thus, the recommended renal postbiopsy period is 24 hours. [Medline]. Laparoscopic renal biopsy has recently been reported as an alternative to open renal biopsy… The use of 14 gauge needles is preferable for clean kidneys. Contraindications to kidney biopsy are associated with patient characteristics that increase the risk for significant postprocedure bleeding (Table 2). The volume of the hematoma is not a therapeutic decision-making element per se, although most hematomas requiring therapeutic intervention are larger than those of asymptomatic patients. Many studies have attempted to compare TAP to bleeding time in the detection of primary haemostasis disorders. In limited circumstances, alternative methods for kidney biopsy may be indicated. Harrison, K L. Renal dysfunction due to an arteriovenous fistula in a transplant recipient. However, renal biopsy is indicated, and as soon as possible, for any patient with ARI of unknown aetiology in order to allow a diagnosis of certainty and to initiate an appropriate treatment. Renal biopsies may indicate the degree of disease activity, and may be used to evaluate the effectiveness of the treatment. What one finds on a renal biopsy is a function of whom one chooses to biopsy. Surveillance includes clinical examination, assessment of pain, diuresis and hematuria, and regular measurement of blood pressure and heart rate. (2004). UpToDate. The sampling is carried out after local anesthesia with Xylocaine. The advantage of these techniques is mainly the visual control of hemostasis. Its positive predictive value of bleeding in a non-selected population is low and false negative results would give false security.“The College of American Pathologists” and “The American Society of Clinical Pathologists” do not recognize bleeding time as a routine preoperative test without significant prior bleeding. Nevertheless, the diagnosis must be a diagnosis of certainty because it is difficult to decide a heavy immunosuppressive treatment without histological evidence. 1991 Nov. 18(5):593-9. TAP abnormalities are not specific to specific platelet involvement and should be interpreted in conjunction with other tests. The advantage of these techniques is mainly the visual control of hemostasis. Thus, it is important to establish the diagnosis of nephropathies in patients with proteinuria> 1.5 g / 24 hours, although sometimes the therapeutic implications remain modest. The majority of the hematomas are asymptomatic and small. [Medline]. Biopsy is particularly useful in early graft dysfunction or delayed function recovery. However, this system is accompanied by a higher incidence of capsular perforation, requiring systematic radiological monitoring during surgery to detect active bleeding and allow selective embolization. Percutaneous renal biopsy has become a relatively safe procedure with life-threatening complications occurring in less than 0.1% of biopsies in recent reports. All material on this website is protected by copyright, Copyright © 1994-2021 by WebMD LLC. These patients receive a protocol of corticosteroid therapy, the biopsy being only carried out in the corticoresistant forms. Mehta R, Cherikh W, Sood P, Hariharan S. Kidney Allograft Surveillance Biopsy Practices Across US Transplant Centers: A UNOS Survey. The puncture point is chosen preferably at the lower pole of the left kidney, less mobile than the right kidney, and with a lower risk of injury to the inferior vena cava. Retrospective studies have shown a better efficacy of ultrasound-guided renal biopsies compared to techniques without direct visualization. Inability of the patient to comply with instructions during renal biopsy is another major contraindication. Multiple systemic diseases such as amyloidosis, myeloma, sarcoidosis or drug-related complications can be diagnosed by renal biopsy. Complication despite the changes in technique function in relation to the manual technique “ on the needle ” 48.. Be the cause of acute renal failure may also benefit from a single kidney can used.
