Abstract

Background: Renal biopsy has an important role in the evaluation of renal disease. A sufficient amount of renal tissue in biopsy sample is required for pathologic diagnosis. The common method of renal biopsy (Blind method) is used for years. Today, new techniques for renal biopsy have been considered from which the most important biopsy techniques are CT scan-guided biopsy and real time ultrasounography. The purpose of this study was to determine the adequacy of renal biopsy samples of adults prepared by mentioned different methods. Methods: In this descriptive cross-sectional study, data of 788 patients undergoing renal biopsy in Al- Zahra and Noor hospitalsin Isfahan, Iran during 3 years were analyzed. Findings: Adequacy of biopsy specimens was appropriate in 74% of cases. Adequacy of biopsy specimens was higher in non transplanted kidnies. The trend to using new methods of renal biopsy has been increased among specialists during the study. The Adequacy of biopsy specimens in blind method, CT scan-guided biopsy, and real time ultrasounography was 75.2%, 66.4%, and 77.6% respectively (P > 0.05). Conclusion: According to the findings of current study, the advantages of new biopsy methods than traditional blind method have not been demonstrated but the growing experience in this area was considerable. In addition, sufficient experience was derived regarding the blind method of renal biopsy. © 2011, Isfahan University of Medical Sciences(IUMS). All rights reserved.
