Introduction
The urinary catheter generally refers to the indwelling urinary catheter. Under normal circumstances, silicone catheters are used for durations up to one month. Currently, the main materials used for clinical urinary catheters are latex and silicone. Silicone catheters are relatively soft, have a smoother surface, cause less damage to the urethra during insertion, and have a relatively larger internal diameter, allowing faster urine flow and reducing the risk of blockage.
Generally, silicone catheters can be used for about one month. Specific details are as follows:
Currently, the main types of urinary catheters used clinically are made of latex and silicone. Silicone catheters are relatively soft, have a smoother surface, cause less urethral damage during insertion, and typically have a larger internal diameter, allowing faster urine flow and reducing the risk of blockage. Latex catheters are less prone to biofilm formation but are stiffer, have a rougher surface that may injure the urethra, and possess a narrower lumen, resulting in slower urine flow and a higher likelihood of obstruction. Generally, silicone catheters should be replaced approximately once a month, while latex catheters should be changed every two weeks, which effectively helps reduce the risk of urinary tract infections.
Patients are advised to seek timely medical attention when experiencing discomfort and to follow standardized treatment under the guidance of a physician, which promotes recovery.
