PERCUTANEOUS ULTRASOUND-GUIDED NATIVE KIDNEY BIOPSY A SINGLE CENTRE EXPERIENCE

AbstractAim To study the indications, spectrum of biopsy proven renal disease, complications and rate of inadequate biopsy specimen.Materials and Methods Retrospective analysis of the histopathological reports and clinical data were reviewed for all native kidney biopsies performed from January 2007 to April 2011.Results A total of 168 native kidney biopsies were performed. There were 87 males (51.8) and 81 females (40.2). Age distribution showed 25 cases (Group I) (14.9) were 18 years age, 101 cases (Group II) (60.1 ) were 18 years and 50 y and 42 cases (Group III) (23.8) were 50 years age. The most common cause indicated for percutaneous kidney biopsy was nephrotic syndrome. Minimal changes disease (MCD) was a predominant lesion in group I and membranous nephropathy (MN) was the commonest pattern in groups II and III. A mean of 12.836.38 glomeruli were present in each specimen. The common complications of the procedure were pain at the biopsy site in 05 patients (3) and gross haematuria in 04 patients (2.3) of the total patients.Conclusions The most common histological finding for primary glomerular disease following percutaneous kidney biopsy was MCD and MN. Renal biopsy was with minimal rate of complication in our practice. Real-time sonographic guidance in combination with an automated core biopsy system is a safe and accurate method to perform percutaneous renal biopsy.
