简要总结
This study is a multicenter, randomized controlled study, with the urinary tract infection rate at the time of catheter insertion for 1 week as the primary end point. By comparing the clinical safety and effectiveness of two kinds of urethral catheters, to evaluate the clinical application effect of one kind of urethral catheters.

结局指标
主要结局
Urinary tract infection rate
时间窗: one week
In accordance with the "Diagnostic Criteria for Catheter associated Urinary Tract Infection" in the "Technical Guidelines for the Prevention and Control of Catheter associated Urinary Tract Infection (Trial)" formulated and issued by the Ministry of Health in 2011. Although the patient has no symptoms, he or she has endoscopic examination or catheterization within one week. If the number of Gram positive cocci colonies in urine culture ≥ 10 has 4 cfu/ml, and the number of Gram negative bacilli colonies ≥ 10 has 5 cfu/ml, he or she should be diagnosed as asymptomatic bacteriuria. If the patient has urinary tract irritation symptoms such as frequent urination, urgent urination, and painful urination, or has lower abdominal tenderness, renal area percussion pain, with or without fever (\>38.0 ℃), it is symptomatic bacteriuria.
