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

Abstract

background: renal biopsy is a fundamental tech-nique in the study of renal allograft pathology. it is essential to know its complications since it is the more aggressive procedure morbidity and mortality.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, retrospec-tive 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 com-plications (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 com-plications (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 per-formed 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
