How-ever, as this procedure is invasive and has inherent risks, its safety must be established. Objective: To determine the safety of percutaneous renal biopsy in pediatric orthotopic renal transplanta tion. Methods: Percutaneous renal biopsies performed on pediatric orthotopic renal transplants in a single cen ter between 1987 and 2010 were studied. Biopsy specimen adequacy and post-procedure complications were reviewed by prospectively collected data. Results: A total of 54 ultrasound ¡°real-time¡± guided biopsies in 25 patients were performed. Minimum specimen adequacy was achieved in 98% of biopsy specimens. No major complications were identified; 6% of patients developed minor complications¡ªe.g., grade 3 macroscopic hematuria that did not require intervention. Conclusion: Percutaneous renal biopsies using ¡°real-time¡± ultrasound guidance on pediatric orthotopic kid-ney transplants is safe. %K Kidney transplantation %K Biopsy %K Safety %K Pediatrics %U http://home.sums.ac.ir/~habibzaf/ojs/index.php/IJOTM/article/view/99/179
