RESUMO
BACKGROUND: Although several risk factors associated with complications after renal biopsy (RB) have been identified, the gold standard for RB procedures remains to be defined. Practices vary widely among nephrologists, depending on personal experience and the availability of particular techniques. The purpose of our study was to depict the main aspects of the practice of RB in adults in France. METHODS: Members of the Société de Néphrologie in France were asked to participate in a questionnaire survey on RB procedures. RESULTS: Eighty-eight nephrologists from 74 units (27 in teaching hospitals, 35 in public general hospitals and 12 in private centres) participated in our study. Native kidney and graft biopsies were performed in 73 and 35 units, respectively. RB activity was highly variable among units, ranging from several hundred to <10 per year. Transjugular renal biopsy was judged to be smoothly accessible in 28 out of 73 units (38.4%). Significant variations in practices were observed regarding patient information before RB, assessment of haemorrhagic risk factors, management of patients with antiplatelet agents and haemorrhagic risk factors, and radiological guidance. Early discharge (<12 h) was the rule in 3 (4.1%) units for native kidney biopsies and in 10 (28.6%) units for graft biopsies. CONCLUSIONS: Our study is the first to provide a representative picture of 'everyday' RB practices in a country. Important variations in procedures were observed. Our study may represent a preliminary step for the elaboration of guidelines for all aspects of RB practices.

European and American recommendations have recently been published for the treatment of proliferative lupus nephritis (LN). This study aimed to describe current practice in France. An electronic survey was sent to French nephrologists and internists via their scientific society between March and December 2012. One hundred and nine specialists (60 internists, 48 nephrologists and 1 rheumatologist), mostly from hospitals, completed the survey. Low-dose cyclophosphamide (Euro-Lupus) was the first induction immunosuppressive therapy used (67%), followed by mycophenolate mofetil (MMF) (20%) and high dose CYC (NIH, 9%). Maintenance immunosuppressive therapy after an induction with CYC was preferentially MMF (58%), versus 14% for azathioprine (AZA) and 25% using either MMF or AZA without preference. After an induction with MMF, maintenance treatment was mainly MMF (77%). Antimalarial drugs were prescribed systematically by 86% of specialists. In patients in stable remission, maintenance treatment was withdrawn after 2 years (40%), 3 years (25%) or more (34%). Low-dose corticosteroids were continued in the long-term by 54% of specialists. No difference was observed between nephrologists and internists, even in the prescription of antimalarials. Treatment of proliferative LN in France is homogenous enough and is consistent with recent international recommendations.

BACKGROUND: Although several risk factors associated with complications after renal biopsy (RB) have been identified, recommendations for RB procedures are still lacking. Our working group, appointed by the scientific commission of the Société de néphrologie in France, aimed to depict the main aspects of the practice of RB in adults in France, before establishing some guidelines. METHODS: Members of the Société de néphrologie in France were asked to participate to a questionnaire survey on RB procedures. RESULTS: Eighty-eight nephrologists from 74 units (27 in teaching hospitals, 35 in public general hospitals, and 12 in private centers) participated in our study. Native kidney and graft biopsies were performed in 73 and 35 units, respectively. RB activity was highly variable among units, ranging from several hundred to less than ten per year. Transjugular RB was judged to be smoothly accessible in 28 out of 73 units (38.4%). Significant variations in practices were observed regarding patient information before RB, assessment of hemorrhagic risk factors, care of patients with antiplatelet agents and hemorrhagic risk factors, and radiological guidance. Early discharge (<12 hours) was the rule in three (4.1%) units for native kidney biopsies and in ten (28.6%) units for graft biopsies. CONCLUSIONS: Our study is the first to provide a representative picture of "everyday" RB practices in a country. Consensual recommendations on all points mentioned are provided here.
