Open Renal Biopsy (1 st Reot)

Abstract

With the performance of percutaneous renal biopsy, the open renal biopsy is recently being carried out by us amounting totally to 27 cases up to date, 2cases of which were done bilaterally and 5 cases wore the case of being already oneside nephrectomised. Our open method is able to be performed under the direct observation on the kidney. Knives are available if necessary for getting the ample materials. Probably because the depth-accomodation of the puncture is easily feasible and styptic defence from the bleeding is comlete, the macroscopic hematuria is less found after the biopsy than percutaneous one and the microscopic hematuria disappears within 48 hours on the case of being unilaterally nephrectomised. Recently Morales et al. reported the method of the open renal biopsy like ours. Discussion of its safety, profiis and outline of the method will be introduced.
