The application value of computer graphics imaging technology in diagnosis of postoperative complications of kidney stones / 实用放射学杂志

ABSTRACT

Objective To evaluate the clinical application value of computer graphics imaging technology in combination with CT urography in the diagnosis of postoperative complications of kidney stone.Methods 1 7 patients with postoperative complications of kidney stones underwent 64-detector CT urography examination.The images were transferred by network to a separate workstation to perform volume rendering (VR),maximum intensity projection (MIP),multiplanar reconstruction (MPR)and curved planar re-construction (CPR).All the postprocessing images were retrospectively analyzed.Results Postoperative complications were found in 1 7 patients including 13 with urinary residual stones,1 with severe hydronephrosis and twisted ureter,1 with residual stone in du-plex kidneys,1 with renal parenchyma rupture,1 with ureter rupture,1 with urine leakage of postcaval ureter,1 with renal hemor-rhage,1 with pleural effusion,and 1 with residual stone of multiple renal cysts.Conclusion Postoperative complications of kidney stones can be clearly demonstrated by computer graphics imaging technology in combination with CT urography,which may provide more information for treatment.
