Abstract:
Polymer polyvinylpyrrolidone (PVP) can be described as the main coating. After heating and curing, it is able to build a strong adhesion to the latex catheter for creating a durable and effective hydrophilic coating. In this study, we aim to explore the advantages and disadvantages of the new super lubricath latex catheter PVP coating compared with the common latex catheter. 148 patients who participated in the study were completely randomly divided into two groups, the observation group and the control group. When the urinary catheter was incubated, indwelling in subjects' body, and removed from the subjects, the researchers accordingly recorded the subjects' comfort feedback, device safety evaluation and the patient's vital signs, relevant blood and urine examination index, electrocardiogram (ECG) changes and recorded various adverse events. PVP super lubricath coating latex catheter offered better comfort, less damage to the urethra, and no significant disadvantage in safety compared to regular latex catheters, improving quality of care and patient satisfaction compared to regular latex urinary catheters.

Urethra
The anatomy of the urethra differs between males and females. In females, the urethra is short, measuring about 3–4 cm in length, and opens anterior to the vaginal opening. In males, the urethra is longer and passes through the penis, serving dual purposes: expelling urine and ejaculating semen. The male...
