Urinary Catheters, Urinary Tract Infection
Conditions
Brief summary
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.
Interventions
DEVICEdisposable urinary catheter
The trial group was intervened with disposable sterile urinary catheter. The model of the trial group includes two chamber type (Fr8, Fr10, Fr12, Fr14, Fr16, Fr18, Fr20, Fr22, Fr24) and three chamber type (Fr16, Fr18, Fr20, Fr22, Fr24).
DEVICEsuper smooth antibacterial urinary catheter
the control group was intervened with ultra smooth antibacterial catheter. The control group models include single chamber (6Fr, 8Fr, 10Fr, 12Fr, 14Fr, 16Fr, 18Fr, 20Fr, 22Fr, 24Fr), double chamber (6Fr, 8Fr, 10Fr, 12Fr, 14Fr, 16Fr, 18Fr, 20Fr, 22Fr, 24Fr, 26Fr, 28Fr, 30Fr), and three chamber (16Fr, 18Fr, 20Fr, 22Fr, 24Fr, 26Fr)

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Urinary tract infection rate | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| level of urethral irritation | 10 minutes after catheterization | Level 0, no discomfort at all; Grade I, slight discomfort, but tolerable; Grade II, moderate discomfort, intolerable, urgency of urination, urethral pain, abdominal distension; Grade III, severe discomfort, extremely intolerable, obvious distension of lower abdomen, urethral pain, urgency of urination, and the desire to pull out the catheter, accompanied by restlessness, increased heart rate, and elevated blood pressure. |
| Incidence of device related adverse events | 72 hours | The safety of clinical use of the device was evaluated based on the incidence of adverse events related to the device that occurred after the subject placed the tube. Including: balloon leakage, rupture, catheter self falling off, difficulty in pulling out catheter, catheter blockage, urine retention, urine leakage, hematuria, urethral injury, etc; It can be judged according to clinical experience, and imaging methods can be used when necessary. |
| time of catheter duration | one week | Time from insertion to removal of catheter |
| Success rate of catheterization | 10 minutes after catheterization | The success of catheterization is based on the evaluation of each instrument, which can be placed at the catheterization site as expected and catheterization can be carried out smoothly. |
| rate of packaging integrity | 10 minutes after catheterization | — |
| rate of device defect rate | 10 minutes after catheterization | The package is damaged, the balloon cannot be inflated, and the balloon leaks or breaks |
| rating of operation convenience | 10 minutes after catheterization | Including excellent: very convenient, good: relatively convenient, poor: poor convenience |
