FIELD: medicine.SUBSTANCE: invention refers to medical equipment, namely to a device and a related method for urinary catheterisation and dilation of the urethral structure. The urinary catheterisation device comprises a catheter and a guide pin. A catheter comprises an elongated body with a distal end and a proximal end, a drain hole and a separate guide passage extending through it. The guide pin passes through the guide passage and serves to guide the introduced catheter. At the proximal end of the elongated body or near it, there is a lubrication port. The lubrication port comprises a side branch for connecting a liquid with the guide passage to introduce a liquid lubricant of the guide pin into the guide passage. The method for urinary catheterisation involves lubricating the above guide pin arranged in the guide passage extending through the above catheter； extending the distal end of the guide pin into the urethra and advancing the guide pin along the urethra into the urinary bladder； advancing the catheter above the guide ping until the distal ends of the catheter penetrates into the urinary bladder； and removing the guide pin from the urethra and catheter. A kit for urinary catheterisation comprises the above catheter, guide pin and sterile package of the catheter and guide pin. The package is opened to inject the liquid lubricant of the guide pin through the lubrication port to lubricate the guide pin in the guide passage, through which the guide pin extends, and that portion of the guide pin, which extends out of the distal end of the catheter.EFFECT: invention provides the higher safety of the procedures, simplifies and accelerates the device insertion.25 cl, 5 dwgИзобретение относится к медицинской технике, а именно к устройству и связанному с ним способу для мочевой катетеризации и расширения структуры мочеиспускательного канала.
