ABSTRACT
Objective:To investigate the risk factors related to urinary tract infection after indwelling ureteral D-J tube in pregnant women with acute renal colic.Methods:Clinical data of 109 pregnant women with acute renal colic undergoing indwelling ureteral D-J tube in emergency department of Taizhou Hospital or Enze Hospital from January 2008 to December 2019 were retrospectively analyzed. There were 31 cases (28.4%) with urinary tract infection after discharge and before delivery (infection group) and 78 cases without infection (non-infected group). Univariate and multivariate logistic regression analyses were used to evaluate the risk factors of urinary tract infection after ureteral D-J tube insertion.Results:In 109 patients the average age was 28 (25,33) years, the average gestational age was 26 (21,31)weeks, and the average body mass index (BMI) was 24.84 (22.60,27.43) kg/m 2. Compared with the non-infected group, the infection group had a higher rate of positive urine culture [38.7%(12/31) vs. 15.4%(12/78), χ2=6.56, P=0.010] and diabetes [45.2%(14/31) vs. 11.5%(9/78), χ2=13.86, P<0.001], and a lower gestational age [23(20,28) vs.27(21,32) weeks, Mann-Whitney U test, P=0.006]. Multivariate analysis showed that diabetes( OR=7.739,95 %CI:2.579-23.223, P<0.001), positive urine culture( OR=3.249,95 %CI:1.131-9.330, P=0.029), and gestational age( OR=0.201,95 %CI:0.042-0.955, P=0.044) were independent risk factors for urinary tract infection in pregnant women with acute renal colic after ureteral D-J tube insertion. Conclusion:History of diabetes, gestational age, and positive preoperative urine culture are risk factors for urinary tract infection after ureteral D-J tube insertion in pregnant women with acute renal colic.
