RESUMEN
Objective To discuss the application value of computer graphic imaging techniques combined with CT urography in surgical scheme selection for upper urinary calculi.Methods 97 cases with complex upper urinary calculi underwent 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 reconstruction (CPR).All the post processing images were analyzed for selecting the appropriate surgical scheme.Results The 97 cases were treated properly according to their CT urography examination images,and all patients recovered without complications.Conclusion Urinary calculi and slight changes in the anatomical structure of upper urinary tract can be clearly demonstrated by computer graphics imaging techniques combined with CT urography,which may provide more information for disease diagnosis and selection of surgical scheme.

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.
RESUMEN
Objective To investigate the effects of prostatitis on secretory alterations of urethral glands in rats.Methods Twenty adult Sprague-Dawley rats were randomly divided into prostatitis group and control group.The prostatitis group(n=10) was injected with 0.1 ml Freund's complete adjuvant at each lateral lobe while the control group(n=10) with 0.1 ml 0.9% physiological saline.Two weeks later the rats were killed and the urethral glands were harvested for pathologic examination and immunohistochemical staining.Results ① There was a great quantity of lymphcells and mononuclear cells infiltrating the prostate gland in prostatitis group while there was no inflammatory cells in control group.② AB-PAS pathologic examination results in urethral glands showed that the grume area,diameter,optical density in control group were significantly less than those of the prostatitis group(P
