Objective To evaluate the efficacy, advantages and shortcomings of micro-percutaneous nephrolithotomy in treatment of uncomplicated ureteral calculi.Methods Clinical data were collected from 126 patients with a failure treatment of history by ESWL (extracorporeal shock wave lithotripsy) and RIRS (retrograde intrarenal surgery) in treatment of upper ureteral calculi (< 3.0 cm) from June 2015 to May 2016. Antegrade percutaneous access was obtained by B-type ultrasound guidance. Micro-PCNL was done using YAG laser fiber or pneumatic through the ureteroscope (F4.5~F6.5、F6.0~F7.5, 315 mm) to disintegrate the stones. The calculi clearance rate, operation time, operative hemorrhage, length of hospital stay and complications of the patients were analyzed after operation.ResultsThe calculi clearance rate was 88.9%, the operation time was 15~75 min, the operative hemorrhage was 15~35 ml, the length of hospital stay was 5~10 d. Only one patient need the second stage surgery because of intraoperative hemorrhage affected the surgical ifeld. No patients occurred massive hemorrhage, pneumothorax, bowel and other complications such as organ damage.Conclusion Micro-PCNL had a good clinical curative effect and security in treatment of uncomplicated ureteral calculi, which was worthy of promoting clinically.

Objective To evaluate the effect of combined detection of cervical E 6/E7 and liquid based cytology(TCT)in the screening of cervical cancer.Methods A total of 206 cases of high-risk patients with cervical cancer from March 2015 to March 2017 in Yongding Hospital of Suzhou were taken the cervical E6/E7 detection and TCT two screening methods respectively,and the pathological diagnosis was taken as the gold standard,the efficiency difference among TCT,cervical E6/E7 detection,and the com-bined detection of cervical cancer was compared.Results The sensitivity and negative predictive value of E6/E7 were significantly higher than those of TCT(P<0.05).The specificity of TCT was significantly higher than that of cervical E 6/E7(P<0.05).The accuracy of combined diagnosis was significantly higher than that of cervical E6/E7 and TCT alone.The difference was statistically significant(P<0.05).Compared with the cervical E6/E7,the specificity and positive predictive value of the combined diagnosis were higher,and the difference was statistically significant(P<0.05).The sensitivity and negative predictive value of the combined diagnosis were significantly higher than those of TCT,and the difference was statistically significant(P<0.05).The receiver oper-ating characteristic curve(ROC curve)showed that the area under the combined diagnostic curve(AUC)was significantly higher than that of the cervical E6/E7 and TCT alone,and the difference was statistically significant(P<0.05).Conclusion Cervical E6/E7 detection has a low specificity,and sensitivity of TCT is low;the combined detection of cervical E6/E7 detection and TCT has a high screening accuracy,and can improve the sensitivity and specificity of individual diagnosis.
