Abstract 【Objective】To discuss the therapeutic effect of double-J stent indwelling time in treatment of urinary tract calculi complicated with infection. 【Methods】From September 2012 to October 2016, the clinical data of 85 patients with urinary calculi and infection were analyzed. The patients were divided into 3 groups: group A (3～5 d,n=23 ), group B (6～7 d,n=28 ) and group C (＞7 d,n=34 ) according to the time of double J catheter indwelling before operation. The patients were divided into two groups: group A (3~5 days), group B (n=28) and group C (>7 days). The clinical data, hematuria and postoperative complications of the three groups were compared and analyzed before and after operation.【Results】There was no significant difference among the three groups in the diameter of stone, the distribution of operation site, the time of operation, the time of stone drainage after operation and the proportion of percutaneous nephrolithotripsy (P>0.05). There was no significant difference in blood, urine white blood cell count (WBC) and positive proportion of urine culture between the three groups before indwelling double J tube (T1), at the moment of indwelling double J tube (T2) (P>0.05). The blood and urine WBC of group A were significantly higher than those of group B and group C (P<0.05). The incidence of postoperative complications in group A was 69.57% (16/23), which was significantly higher than that in group B 35.71%(10/28)and group C35.29% (12/34) The difference was statistically significant(χ2=6.671,P=0.036＜0.05).【Conclusion】The infection of ureteral calculi could be effectively controlled after 6～7 days of double J stent indwelling, and the incidence of postoperative complications is lower.
