摘要：Urethral catheters are widely used in various settings, such as the perioperative period, in patients who are unable to urinate on their own. Stimulation of the urethra and bladder mucosa that occurs due to catheterization is accompanied by discomfort, a feeling of residual urine, and pain [1]. Furthermore, strong discomfort and pain can also occur during catheter removal. Lidocaine, a local anesthetic, has been widely used by urologists for cystoscope insertion for many years, due to its well-known analgesic effects during the procedure [2,3]. We decided to use lidocaine to alleviate the pain that occurs during urethral catheter removal. However, a device that allowed the administration of a local anesthetic into the urethra did not previously exist. In the present study, we therefore developed a catheter that is structured such that it can administer lidocaine into the urethra. To achieve this, we created two holes in a ready-made catheter to inject the drug solution. In the present study, to assess the effectiveness of this newly developed catheter, patient pain during catheter removal was evaluated using a visual analogue scale (VAS). The safety of using this catheter was also examined.
