Our hospital is one of the early hospitals in China to carry out endoscopic diagnosis and treatment. In 1958, we carried out cystoscopy, and in 1982, we carried out transurethral electrodesiccation, and we were also one of the first hospitals in China to carry out minimally invasive laparoscopic surgery. At present, the annual volume of laparoscopic surgery has exceeded 1500 cases, and has developed into a leading urological laparoscopic diagnosis and treatment center in China, integrating clinical, scientific research and teaching. Our department is the largest laparoscopic and minimally invasive treatment and training center in urology in China, which can successfully complete not only routine laparoscopic surgeries (such as laparoscopic radical nephrectomy, partial nephrectomy, full-length ureterectomy, pyeloplasty, adrenal tumor resection, renal/parapelvic cyst de-topping, ureterotomy and lithotomy, retroperitoneal lymph node dissection, spermatic vein ligation, etc.), but also Some difficult urological laparoscopic surgeries, such as laparoscopic radical prostate cancer treatment with preserved sexual nerve, single-hole radical kidney cancer treatment, single-hole total cystectomy, live donor kidney removal and total bladder removal in situ cystectomy, are also becoming more and more mature. Our department has the largest number of laparoscopic living donor nephrectomy in China, more than 100 cases of laparoscopic radical prostate cancer treatment in 2010, single-port laparoscopic technique has become a routine operation, and laparoscopic total bladder dissection in situ Studer’s cystectomy also ranks among the top in China, with fast postoperative recovery and no serious complications, which is generally praised by patients and peers. In 2008, our urology department was approved as one of the first “training bases of endoscopic/laparoscopic treatment technology of the Ministry of Health” in Beijing. “in Beijing. In addition, we have made minimally invasive laparoscopic techniques one of the continuing education programs for attending physicians and residents in our department, and established a strict qualification examination system for minimally invasive laparoscopic surgery, which enables physicians with intermediate titles or above in urology to master and independently perform laparoscopic surgery, ensuring the safety and popularity of minimally invasive laparoscopic surgery techniques. Special Surgery (1) Laparoscopic radical prostate cancer surgery with preservation of neurovascular bundle (NVB): In recent years, the incidence of prostate cancer in China has increased significantly, and more patients with limited prostate cancer have been diagnosed in time. With the advancement of anatomy, improvement of surgical techniques, and the promotion of the concept of tumor eradication while improving patients’ life treatment, the nerve-preserving retropubic prostate cancer radical surgery, especially the trans-laparoscopic prostate cancer radical surgery, has gradually become the development trend of early prostate cancer treatment, and now the nerve-preserving laparoscopic prostate cancer radical surgery has become the standard surgery for suitable patients in Europe and America. The procedure is gradually being performed in large lumpectomy centers in China. This procedure has become the standard method for the treatment of limited prostate cancer in our department. Foreign literature reports that there is no significant difference in complications, recovery time and margin positivity rate between laparoscopic radical prostate cancer treatment with preservation of NVB and radical retropubic prostate cancer treatment. Our experience shows that laparoscopic radical prostate cancer treatment is anatomically fresh, precise, minimally invasive and safe, and more conducive to preservation of neurovascular bundle. Long-term evaluation of tumor control, urinary control ability and erectile function showed that this technique is similar to anatomical retropubic prostate cancer radical surgery, while patients’ postoperative recovery is significantly better than classical open surgery and laparoscopic surgery. (2) Laparoscopic radical cystectomy + lymph node dissection + Studer in situ cystectomy: Bladder cancer is the most common malignant tumor in the urinary tract, and radical cystectomy with lymph node dissection is the standard treatment for muscle-invasive bladder cancer, and laparoscopic radical cystectomy with lymph node dissection has the same results as open surgery, with the advantages of less trauma and faster postoperative patient recovery. Studer in situ cystectomy does not require an abdominal wall stoma, is simpler to reconstruct a new bladder, has fewer complications, ensures low pressure and anti-reflux status, and has a higher postoperative quality of life, making it the preferred approach for urinary diversion in our department in recent years. Foreign literature reports that laparoscopic total cystectomy is not significantly different from open surgery in terms of operative time, bleeding and complications, but the amount of postoperative pain medication, time to resume normal diet and length of hospital stay are significantly less than open surgery. Our department’s experience shows that due to the magnification of the lumpectomy lens, the intraoperative anatomy is clearer and the surgical operation is more delicate during total cystectomy, especially in The procedure is more delicate, especially in freeing the seminal vesicle and the posterior lateral neurovascular bundle of the prostate. In our department, we use the extraperitoneal method to create a new bladder, and we create Studer’s new bladder and perform the ureter-neobladder anastomosis outside the body, which avoids the disadvantage of slow suturing and knotting under the lumpectomy and significantly shortens the operation time. Both foreign data and our experience show that there is no significant difference in intraoperative bleeding, intraoperative blood transfusion and hospital stay between Studer in situ bladder and other clinically used ileal bladders. However, Studer in situ bladder patients have a higher quality of life postoperatively because they do not have to have an abdominal wall stoma, do not have to wear a urinary collection bag, and have good recovery of urinary control function. (3) Posterior laparoscopic resection of giant adrenal tumors: posterior laparoscopic resection of adrenal masses is the gold standard for the treatment of adrenal tumors. before and after 2005, it is generally believed that posterior laparoscopic resection of adrenal masses is suitable for adrenal tumors <6 cm in diameter, and larger adrenal tumors should be selected by transabdominal approach or open surgery. The use of posterior laparoscopic resection of adrenal tumors larger than 6 cm in diameter is controversial because of the difficulty and long operation time, in addition, huge adrenal tumors are often rich in blood supply, which increases the risk of bleeding and reduces the safety of the operation. With the gradual proficiency of laparoscopic technique in our department and the accumulation of operator's experience, we resected huge adrenal masses of 6-11 cm in diameter via retroperitoneum in 2005, and the largest diameter of tumor resected in 07 reached 13 cm. Our experience shows that retroperitoneoscopic resection of huge adrenal masses is less disturbing to the abdominal cavity, less risk of organ damage, and the postoperative recovery period of patients is significantly shorter than that of laparoscopic and open surgery. (4) Transumbilical single-port laparoscopic surgery (radical kidney cancer surgery, radical total cystectomy, etc.): Our department started to carry out transumbilical single-port laparoscopic surgery in early 2010, which is one of the first centers in China to carry out such surgery. This surgery is a new technology in the international arena. Due to the special characteristics of the single-port channel, this surgery is more complicated than standard laparoscopic surgery, with a longer learning curve, and requires a more proficient foundation in laparoscopic surgery to perform. At present, our center has completed 5 cases of transumbilical single-port laparoscopic renal cyst depancreate, 10 cases of transumbilical single-port laparoscopic radical nephrectomy for renal cancer, 2 cases of transumbilical single-port laparoscopic simple nephrectomy, 1 case of transumbilical single-port laparoscopic adrenal tumor resection, and 8 cases of transumbilical single-port radical cystectomy for bladder cancer, all without obvious surgical complications. The single-port laparoscopic technique is less traumatic, with fast postoperative recovery and inconspicuous postoperative surgical scar, and the treatment effect is comparable to that of standard laparoscopic surgery, which is the preferred treatment for young women and beauty lovers and one of the development directions of minimally invasive surgery. The homemade single-hole laparoscopic channel of our department is easy to use and inexpensive, which greatly reduces medical costs on the basis of ensuring surgical safety and is more suitable for our national conditions.
