Abstract:
Objective To identify free kidney stones,diverticular stones and renal papillae calcification by means of plain and enhanced CT scan and to provide definite reference for the physical examination of civil pilots.Methods The cross-section study was used.Twenty-six pilots who were suspected as kidney stone received urinary system GE64 slice spiral CT scan and enhanced scan in Civil Aviation General Hospital.The raw data were processed in workstation.The multi-planar reformation (MPR),volume rendering technique (VRT),maximum intensity projection (MIP) and window modulation were used for image analysis and diagnosis.Then the patients were re-examinated by the electron fiberoptic endoscopy operated by clinicians.Results Eight-three suspect kidney stone lesions were found from 26 pilots.By the imagining and urinary surgery doctors' diagnosis 63 free kidney stones,4 diverticular kidney stones and 16 renal papillae calcifications were determined.Fifty six free kidney stones,4 diverticular kidney stones and 23 renal papillae calcifications were diagnosed by electron fiberoptic endoscopy examination.In 83 suspect cases,the non-invasive diagnosis screened out 76 lesions that were in accordance with the results of electron fiberscope examination.The accuracy was 91.6%.Conclusion The plain and enhanced CT scan coordinated with data process can basically diagnose small,inconspicuous free kidney stones,diverticular kidney stones and renal papillae calcifications.Such non-invasive diagnosis of kidney stone is applicable in pilots physical examination.
