Objective To study the combination treatment of lfexible/lfexible sheath and rigid ureteroscopic lithotripsy (F-ul) for upper and middle ureteral stones. Methods The clinical data of patients diagnosed of upper and middle ureteral stones were collected. The treated group (110 cases):ifrstly treated with rigid ureteroscopic lithotripsy to broke and removed stones through lfexible sheath, then the lfexible ureteroscopic lithotripsy was used to broke and removed stones through lfexible sheath;The control group (110 cases):traditional operation for ureter calculi. The clinical data was compared between the two groups. Results The effective ratio of treatment group is 90.0%, which was better than that of control group (87.3%) (P>0.05). The operation time, stone processing time of treatment group were signiifcantly shorter than those of control group (P 0.05). Conclusion The method of combining flexible/flexible sheath and rigid ureteroscopic lithotripsy for upper and middle ureteral stones was better than that of traditional operation, which worth to be popularize in clincal treatment.

Résumé
OBJECTIVE@#To construct short hairpin RNA interfering expression vector of TDRG1,and detect the specific interfering effect of TDRG1-shRNA expression vector on NTERA-2 cells.@*METHODS@#Oligos for short hairpin RNA targefing for TDRG1 were designed and connected to the expression vector pGPU6/GFP/Neo to construct the TDRG1 shRNA expression vector. The recombinant plasmid TDRG1-shRNA486, TDRG1-shRNA738, TDRG1-shRNA921 and lipofectamine ™2000 were used to generate and transfect shRNA into NTERA-2 cells. Expression of TDRG1 mRNA was assayed by RT-PCR.@*RESULTS@#TDRG1-shRNA expression vector was successfully constructed. TDRG1-shRNA486 was more effective in the suppression of TDRG1 with significant reduction of TDRG1 mRNA.@*CONCLUSION@#TDRG1-shRNA can interfere the expression of TDRG1 in NTERA-2 cells.
