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.
