title: Kidney biopsy in west of Iran: Complications and histopathological findings.
abstract: In this retrospective study, we reviewed the medical records and histopathology findings of 135 patients who underwent renal biopsies at two special hospitals affiliated to Kermanshah medical university during a six-year period (2003-2007). All were performed using Tru-Cut needle under ultrasound guidance. Twenty four specimens were unsatisfactory. There were 38 males (34.2%) and 73 females (65.7%) in 111 patients with adequate specimens (each specimen has more than 5 glomeruli); the mean age was 16.5 years (range 2-64 years). Side effects of the renal biopsies included pain at the site of biopsy in 2 (2.7%), gross hematuria in 1 (0.9%). Nephrotic syndrome was the most common indication for biopsy followed by acute renal failure of unknown etiology and nephritic syndrome. Primary glomerular disease was reported in 78 patients (70.2%) and also secondary glomerular disease in 33 patients (29.7%). Among the primary glomerulonephritis disease, minimal change disease and membranous glomerulonephritis were the commonest findings in children below the age of 16 years. Minimal change disease ranked first in adults whole membranous glomerular disease and focal segmental glomerulosclerosis were more common in the elderly. In all patients lupus glomerular disease was the commonest secondary glomerular disease. We conclude that study on renal biopsy makes final diagnosis which is associated with an acceptably low rate of complications in our practice, and in all, the patterns of renal histology in our study vary slightly from those reported from other countries.
