Abstrakt:	Background and Objectives: Transjugular renal biopsies (TRB) are an alternative when percutaneous ultrasound renal biopsy is contraindicated. Few sites are currently carrying out this procedure, with limited literature existing on the indications, complications and diagnostic yield thereof. The aim of the study is to analyse the indications, diagnostic yield, safety and complications of percutaneous transjugular renal biopsies in our site over the last 15 years. Material and Methods: Retrospective descriptive study of all transjugular renal biopsies performed in our site, the Hospital Vall d'Hebron, between 2003 and 2018. For this, an exhaustive review of the clinical records of patients subjected to this procedure during the study period was conducted. Results: 56 TRBs were performed during the study period. Out of the patients, 31 were men (55.4%) and 25 were women (44.6%), with a median age of 62 years (IQ range 25-75 [52.5-69.5]). More than half presented with haematuria at the time of biopsy, with a median creatinine of 2.69 mg/dL (IQ 25-75 [1.7-4.3]) and median proteinuria at 24 hours of 2000 mg (IQ 25-75 [0.41-4.77]).The mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 140 +/- 26 mmHg and 75 +/- 15 mmHg, respectively. The biopsy was carried out owing to acute kidney failure in 19 patients, chronic kidney disease in 12 patients and nephrotic syndrome in 10 patients; in 15 patients it was carried out for other reasons. The most frequent TRB indication was technical impossibility in 16 of 56 cases (including infracostal kidneys, obesity and COPD), alterations in haemostasis (n = 6), thrombocytopenia (n = 5) and solitary kidney (n = 7). 12.5% of the biopsies were hepato-renal. Histological diagnoses were obtained in two thirds of the renal biopsies. The average number of cylinders obtained was 2.5 ± 1.3, with the average number of glomeruli being 6.6 ± 6.2. The most frequent histological diagnoses were IgA nephropathy, membranoproliferative glomerulonephritis and thrombotic microangiopathy. Three major complications were observed: fornix rupture and two transfusion requirements due to bleeding and subcapsular hematoma. Conclusions: In our site, TRB allowed for a histological diagnosis in 2/3 of patients for whom percutaneous ultrasound renal biopsy is contraindicated. This allowed us to diagnose and subsequently treat said patients. (Copyright © 2020 Sociedad Española de Nefrología. Published by Elsevier España, S.L.U. All rights reserved.)
