| Popis: | 98 Background and Purpose When performing the puncture before the percutaneous nephrolithotomy (PCNL), we usually faced the difficulty of how to localize the posterior calyceal stone or calyx which caused longer procedure time and failure. The aim of this study is to examine whether the use of C-arm computed tomography (CT) during percutaneous nephrolithotomy (PCNL) decreases the procedure time, the risk of bleeding and increases the technical success rate. Materials and Methods Between March 2008 and June 2009, we retrospectively reviewed the data base of radiology to find out 54 patients with complex or big renal stone. There were 39 men and 15 females with mean age of 54.2±11.5 years old. They were referred to our department to perform the puncture before percutaneous nephrolithotomy. Before puncture, the group 1(n=28 with 28 punctures) used only the IVU film or KUB as initial evaluation of the access. The group 2 (n=26 with 28 punctures) used the IVU film and multiplanar C-arm CT images reconstructed from data acquired during C-arm rotation. The desired posterior calyceal stone or calyx to be punctured will be decided. We compared the procedure time, contrast extravasation, significant bleeding, success rate, and residual stone after PCNL. RESULTS The mean procedure time was significantly reduced in group 2 compared with that of the group 1 (26.5±8.8 min vs 37.0±11.6 min, P |
