Abstract:
Objective To assess the efficacy and safety of stenting ureteral stent prior to extracorporeal shock wave lithotrip‐sy(ESWL) for non‐obstructive upper ureter and renal stone .Methods From January 2012 to October 2013 ,a total of 96 patients who met inclusion and exclusion criteria were randomly devided into two groups :a stented group (group B) with a double‐J ureter stent fixed pre‐ESWL and a non‐stented group (group A) treated with ESWL direactly .Outcomes were evaluated in 1 month and then the ureter stent was removed ,another evaluation was taken after 2 months .Results The clearance rate in group A was signifi‐cant higher than that of group B at first month(P=0 .02) ,but group B was significant higher than that of group A at the second month(P=0 .001) .The renal colic rate of group A was significant higher than that of group B(P=0 .001) ,the gross hematuria rate of group B was significant higher than that of group A(P=0 .005) .The comparison of fever ,steinstrasse ,lower urinary tract syn‐drome showed no statistical difference(P>0 .05) .Conclusion Stenting ureter stent may increase the clearance rate of ESWL by 1 session for non‐obstructive upper ureter and renal stone ,but the passage of stones mainly happen after the removing of stent .Stent‐ing can also prevent the morbidity of renal colic without increasing low urinary tract syndrome ,but can increase the morbidity of gross hematuira .
