After the 1990s, laparoscopy began to be used in the field of urology and became popular in the 21st century. In recent years, our department began to take the lead in carrying out laparoscopic surgery in southern Shanxi. Now it has been widely used in the treatment of urological diseases. The basic feature of laparoscopic surgery is to use a trocar needle as a channel to enter the abdominal cavity, use an artificial CO2 pneumoperitoneum to create a space for observation and operation, display the surgical field with a laparoscope and video camera system, and use special surgical instruments instead of the operator’s hands to complete the surgery. Laparoscopic surgical equipment includes video surveillance system, CO2 pneumoperitoneum system, electrodesiccation, electrocoagulation and surgical instrument system. Indications: With the development of laparoscopic technology, almost all urological surgeries can be done laparoscopically at present. The following procedures have been successfully carried out in our department: renal cyst depanalization, adrenal tumor resection, high spermatic vein ligation, nephrectomy, radical nephrectomy, ureterotomy for stone extraction, total ureterotomy for renal pelvic ureteral cancer, and pyeloplasty. The upcoming ones are partial nephrectomy, retroperitoneal lymph node dissection and more complicated radical total cystectomy, ileal cystectomy and radical prostatectomy in the lower urinary tract. Advantages: 1. Small surgical injury, small incision, body wall nerves and muscles from being cut: most of the traditional open surgical incisions in abdominal surgery inevitably injure the body wall nerves, tearing or severing the abdominal wall muscles. In contrast, endoscopic surgery, because of its small and scattered incisions, generally does not injure the nerves of the body wall, and muscle damage is minimal. In addition, the incision pain is minimal and there is usually no numbness around the small incision left by the severed nerves of the body wall. The advantages of the above incision are more prominent in the more obese patients. 2.Surgical effect is sure: it can achieve the effect of open surgery with less bleeding. The enlarged image and excellent light make it quite a bit similar to microsurgery, and the dissection is more precise. Electric knife, ultrasonic knife and other highly sophisticated weapons also make less bleeding. 3. Less organ interference and faster postoperative recovery: laparoscopic surgery not only makes incisional trauma much less severe, but also reduces the inherent trauma of the surgery itself. Since there is no gauze pad abrasion on the plasma membrane surface of the organs, no water volatilization, no scattering of foreign bodies such as dust and talcum powder in the operating room, and no excessive influence on the blood flow of the organs due to pressure pulling, laparoscopic surgery greatly reduces its interference with the organs, and the functional paralysis period of the organs after surgery is greatly shortened. In addition, the postoperative pain is light, and the organ function can be moved to the ground early, and the chance of organ adhesions is greatly reduced. Postoperative complications such as pulmonary infection and deep vein thrombosis are reduced. The postoperative hospitalization day can also be shortened to half of the original one. 4, laparoscopic surgery in the body for surgical operations, in a fully enclosed state for surgery, so the chance of causing abdominal infection is much smaller than open surgery. The postoperative antibiotic time is also short. Therefore, the application of antibiotics and side effects caused by the reduction, colleagues save money. 5, laparoscopic surgery through the electronic video system will be the entire surgical process displayed on the television screen, the operation members can observe, and can be discussed at any time the disease and surgical methods. 6.Surgical route.
