Abstract：
Urinary catheters have been used for more than 3000 years, although materials have changed from wood to silver to rubber. Research continues to try and find the optimal catheter materials, which improve safety and quality of life. Advantages when comparing newer catheter materials are not always obvious but catheters coated with a hydrophilic layer may reduce urethral trauma and the incidence of urinary tract infections. However, extrapolation of the data is limited by lack of end-point standardization and heterogenous populations.

导尿管已经使用了3000多年，虽然材料已经从木头变成银到橡胶。研究继续尝试并找到最佳的导管材料，提高了安全性和生活质量。比较较新的导管材料时的优势并不总是明显的，但是涂有亲水层的导管可以减少尿道创伤和尿路感染的发生率。然而,数据的外推受到缺乏终点标准化和异质性人群的限制.
