Análisis de las complicaciones de la biopsia renal en el paciente trasplantado renal

background: renal biopsy is a fundamental technique in the study of renal allograft pathology. it is essential to know its complications since it is the more aggressive procedure morbidity and mortality. objectives: the main objective of our study is to analyze and identify clinical complications resulting from percutaneous renal biopsy in renal transplant patients. to assess whether a patient clinical factor influencing the onset of these complications. patients and methods: an observational, retrospective study of all patients who underwent percutaneous renal biopsy renal graft between january 2009 and january 2012. were analyzed: age, sex, hypertension, serum creatinine, proteinuria and hemoglobin before and after the biopsy. we defined minor complications (hemoglobin drop greater than 1 g / dl) and major complications (requiring transfusion, surgery, nephrectomy, arteriography, embolization or death). the biopsy was performed by the nephrology team with ultrasound guidance and withdrawing the antiplatelet therapy. results: the number of biopsies performed was 92. the mean age of patients was 47.9 ± 13.2 years and 70.7% were men. there were 2 major complications (2.2%) and both patients had urological bleeding and sepsis, one need a transfusion. minor complications were 14.1%. the graft loss or patient death was not observed. conclusion: percutaneous renal graft biopsy performed by physicians experienced nephrologists under ultrasound guidance in real time, is a low risk procedure, similar to that observed in native kidney. the careful completion of our protocol renal biopsy, optimize the risk benefit ratio of this technique.
