RÉSUMÉ

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.

RÉSUMÉ

Objective To analyze the composition of urinary stones in Taizhou of Zhejiang province.Methods Clinical data of 1 022 patients with urinary stones admitted in Taizhou Hospital of Zhejiang province were retrospectively reviewed.The samples of urinary stones were collected and analyzed by infrared spectrophotometry.Results There were 722 males and 300 females with a male to female ratio of 2.4:1 and with a mean age of (53.4±13.6) years (14-88 years).Among 1 022 patients,the stones with single composition were found in 299 cases (29.3%);the most common single-component was anhydrous uric acid (15.9%),followed by calcium oxalate monohydrate (12.0%).The mixed stones were found in 723 cases (70.7%);the most common mixture was calcium oxalate monohydrate,calcium oxalate dehydrate and carbonate apatite mixture (316 cases,30.9%).Calcium oxalate (58.9%,602/1 022) was the most common major component and frequently seen in upper urinary tract stones,followed by uric acid (21.8%,223/1 022).Uric acid calculi was predominant component in male patients(χ2=30.97,P=0.00),while the rate of infection stones was higher in women (χ2=60.69,P=0.00).The mean age of patients with uric acid stones was 59.4 years,which was older than that with other components (t=7.62,P=0.00).The uric acid stones were more common in upper urinary tract stones(χ2=42.97,P=0.00).The mean age of patients with infection stones was 49 years,which was younger than that with other types of stones(t=4.87,P=0.00).Conclusion Mixed stones with calcium oxalate monohydrate,calcium oxalate dehydrate and carbonate apatite are the predominant urinary stones in Taizhou of Zhejiang province,while the most common single-component stones are anhydrous uric acid stones.Location,age and sex are associated with the types of urinary stones.
