Objective:The accuracy and its affect faltors were studied to evaluate the feasibility of telepathology (TP) diagnosis for renal needle biopsy.Methods:40 cases of renal needle biopsy were included based on the microscopy results.A nephrology doctor and a pathology doctor selected 20 cases each.Digital images were obtained from 3 paths.Then digital images are trans- mitted from Qingtian,Zhejiang to Shanghai.Another pathology doctor mase diagnosis blindly for each case based on the ima- ges and the clinical histories,also evaluating the quality of the pathological images.And the affect factors were discussed.Re- sults:28 diagnosis of those of the 40 cases were absolutely correct,2 essentially correct,4 partially correct,4 wrong and 2 de- layed.Of the 38 cases diagnosed on the spot,the strict accuracy and clinically important one were 73.7% and 89.5% respec- tively.The diagnostic accuracy of the 2 groups whose images were selected by different doctors was identical (strict accura- cy73.7% and clinically important one89.5%).The accuracy of uncommon diseases was obviously lower than that of common diseases (strict one were14.3%、87.1% respectively and clinically important one were 42.9%、100% respectively,P＜0.001). The number of glomeruli selected was positively correlatied with the digitized results of diagnosis (if diagnosis is absolutely cor- rect it gets 3,essentially correct gets 2,partial correct gets 1 and wrong gets 0,P＜0.05).Conclusion:TP disgnosis for renal needle biopsy is feasible and easy.The accuracy of is in our trial can essentially meet the clinical demand.General methods to capture,compress,transmit,display images and diagresis do not influence the diagnostic accuracy.Selecting more renal glo- meruli may improve the diagnostic accuracy.
