Original title: Do you really know the guide wire of urology? Editor's note Surgery is not only a technology, but also an art and a philosophy. Urological surgeons in China have summed up many "small" skills, "small" summaries and "small" experiences while pursuing their own skills. In fact, it is small only because of its small length and small topic, but it is not practical. The purpose of "Small Skills and Great Skills" is to share your experience through the platform of Laikai Medical Official Micro. I sincerely thank Director He Yi and Dr. Wu Lingfeng of Jiaxing First Hospital for their first contribution to us. It is not spring to outshine others, but it is spring to let a hundred flowers blossom. Welcome to discuss in the message area. Do you really know the guide wire of urology? Urological guide wire, as a guide tool for endoluminal surgery, plays an important role in various endoscopic operations in urology. But do you really know what wire you're using? What is the diameter of the guidewire? Top form? Surface coating? Material? Hardness? Wait. Have you ever encountered the situation that the double J tube can not be pushed and wrinkled (Figure 1)? If it's the first time you've used this pair of J tubes, it's possible that your guidewire is too thick. At present, the diameters of guide wires on the market are mainly 0.028 in, 0.032 in, 0.035 in and 0.038 in. According to the different thicknesses of double J tubes, we need to choose guide wires with different diameters. For example, the commonly used 5 Fr ureteral stent tube, the matching stent is often 0.028 in or less than this specification. In addition, some guide wires are coated with hydrophilic coatings, which are very slippery when exposed to water and do not require the use of other lubricants. Zebra guidewire is a common hydrophilic coated guidewire. If there is no guide wire with hydrophilic coating, we need to fully lubricate the guide wire when using it, otherwise the situation in Figure 1 may also occur. But even with a hydrophilic coating,Titanium 6Al4V wire, if the guidewire is thick, there is still no way to pass through the 5Fr stent. Have we experienced ureteral perforation during rigid ureteroscopic surgery or placement of a flexible ureteroscopic sheath? Most of these cases were related to the failure of the ureteral guide wire to be in place, in addition to the violent entry of the endoscope or sheath. When the hard part of the ureteral guide wire has not yet passed through the twisted ureter, it is very easy to cause ureteral injury and perforation by entering the endoscope or sheath. In addition, if the guide wire bends earlier in the ureter or returns, the tip of the sheath will still injure the ureter when the soft sheath is placed. Expand the full text The ureteral guide wire has two ends, and we should fully understand the shape and material of the two ends. For most guide wires, one end is a soft head,titanium round bar, which can be bent and has good passability, while the other end is a hard head, which is generally not suitable for "taking the lead", otherwise it is easy to cause tissue damage, perforation and so on. Of course, there are also guide wires with soft heads for doctors to choose. Many members of the department hold corresponding positions in societies at all levels, and the department is also a postgraduate training point and a GCP drug clinical verification unit. In the past ten years,3d titanium wire, members of the department have completed more than 20 scientific research projects at all levels, held 15 national and provincial continuing education classes, and published more than 80 articles including SCI and first-class journals.
