The development of urological laparoscopic surgery has become unstoppable because of its many advantages such as small surgical operation incision, less damage, less danger, faster postoperative recovery and less complications, and its development has become more and more spacious, penetrating almost every aspect of traditional urological surgery. Along with the rapid development of robotics and electronic communication, laparoscopic surgery will also play a greater role in the field of telemedicine surgery, and we will be surprised to see the wonderful scene of laparoscopic surgery performed by laparoscopic experts on this side of the globe sitting at home for patients living on the other side of the globe. 1. Nephrectomy and radical treatment of renal cancer and pyel cancer Traditional nephrectomy requires a 15-30 cm incision in the waist or upper abdomen, which is traumatic, slow to recover, and leaves scars that damage local aesthetics. Laparoscopic surgery is a good remedy for the above-mentioned shortcomings of traditional surgery. The nephrectomy can be completed by entering through 3~4 small incisions of 0.5~1.5cm in the patient’s lumbar abdomen with special instruments, and then one of the incisions can be enlarged to 4~5cm to remove the kidney. The indications for laparoscopic nephrectomy include: 1) benign renal lesions, such as renal atrophy, hydronephrosis or tuberculous kidney, polycystic kidney, etc. 2) renal cancer below 6 cm. 3) renal pelvic cancer and ureteral cancer. The author has successfully completed hundreds of laparoscopic nephrectomies since he started laparoscopic surgery, and all patients who need nephrectomy now choose to undergo laparoscopic surgery. For patients who need to preserve renal function, laparoscopic partial nephrectomy can also be performed. According to the author, the average hospital stay after traditional nephrectomy in the past was 9.2 days, while the average hospital stay after laparoscopic nephrectomy was about 5 days, which obviously shortened the hospital stay. 2. Renal cyst decortication and polycystic kidney decortication Laparoscopic renal cyst decortication has become the gold standard surgery for renal cyst treatment. The procedure not only can achieve the same effect as open surgery, but also has much less surgical blows and complications, and has now become one of the most carried out laparoscopic urological surgeries in China, which has less damage and faster recovery than open surgery. Congenital adult-type polycystic kidney used to have no effective surgical treatment, often left to its own devices, and eventually entered the uremic phase. Laparoscopic decompression of polycystic kidney can greatly relieve the compression damage of cysts on normal kidney units, slow down the damage of kidney function and prolong the life span. Both of the above-mentioned procedures are standard in our department. At present, the author can perform laparoscopic renal cyst decompression within 15-30 minutes and polycystic kidney decompression within 60 minutes. 3, pyeloplasty and pyelotomy for stone extraction Open pyeloplasty used to be the gold standard for treating obstruction at the pelvic-ureteral junction, but its severe surgical trauma has led to a search for less invasive surgical options. Laparoscopic pyeloplasty can solve many problems due to hypoplasia of the pelvic-ureteral junction and its external ectopic vascular or fibrous band compression. It maintains a high surgical success rate and has the advantage of minimal surgical trauma, and is expected to become the new gold standard for surgical treatment of pelvic-ureteral junction stenosis, and the author has successfully relieved the pain of nearly 100 patients so far. Similarly, as an effective supplement to ureteroscopy and percutaneous nephrolithotomy, laparoscopic pelvic dissection for stone extraction has also been widely performed in our department. 4. Ureterotomy Open ureterotomy is a traditional surgical procedure, but in recent years, ureteroscopic intracavitary lithotripsy and extracorporeal shock wave lithotripsy have enabled more and more patients to avoid the pain of open surgery. To complement the above two treatment modalities, laparoscopic ureterotomy for stone extraction also requires only three small holes to relieve you of the pain caused by stones. 5.Adrenalectomy Traditional adrenalectomy requires the tenth or eleventh intercostal incision, which is 15~20cm long, with the risk of damaging the pleura and causing pneumothorax, much intraoperative bleeding and long postoperative recovery time, and because adrenal tumors are often small in size, open surgery is often difficult for patients to accept. Laparoscopic adrenalectomy only requires 3 small holes in the lumbar region. Due to the magnifying effect of laparoscope, surgery under laparoscope has the advantages of clear anatomical landmarks, less intraoperative bleeding, fast postoperative recovery and short hospital stay, which is the preferred surgical method for adrenal surgery. 6.Partial nephrectomy Laparoscopic partial nephrectomy belongs to high difficulty urological laparoscopic surgery. The benignity and malignancy of kidney tumor need to be clarified by pathological tissue examination, and puncture biopsy may lead to kidney bleeding and tumor implantation and metastasis, etc. Currently, puncture biopsy is not advocated, and patients who were suspected of malignant kidney tumor in the past need open surgery to remove the tumor (partial nephrectomy) and send it for pathological examination, which causes great damage, bleeding and long postoperative recovery time. At present, we adopt laparoscopic partial nephrectomy (renal tumor resection with kidney preservation), which still only requires three small holes of 1~3cm in the lumbar region for surgery, and its immediate and long-term efficacy is the same as that of open surgery, and currently can be the first choice treatment option for renal tumors less than 4.0cm in diameter. 7.Ureteral bladder transplantation Traditional ureteral bladder transplantation is an open surgery with large incision, trauma and long postoperative recovery time for the patient. Laparoscopic surgery requires only 3 small holes, thus the surgery is less traumatic, less painful for the patient and faster postoperative recovery. 8, total cystectomy The traditional total cystectomy surgery is open surgery, requiring an incision around the umbilicus in the lower abdomen, which is traumatic, bleeding, and difficult to operate due to the deep surgical site, which is not easily exposed, and thus the operation takes a long time. Total cystectomy is the largest operation in urology, and only a few urologists can master the operation. The author was the first to carry out laparoscopic total cystectomy in Yibin City on the basis of accumulating a lot of experience in open total cystectomy, and every patient was operated successfully and discharged from hospital with smooth recovery. The author experienced that laparoscopic total cystectomy has the advantages of small surgical trauma (only 4~5 holes are needed), clear surgical field, less bleeding, less postoperative pain, and fast postoperative recovery. And the operation time is shorter than that of open surgery. 9.Radical prostate cancer surgery Traditional radical prostate cancer surgery is open surgery, the operation site is deep and not easy to be exposed, thus increasing the difficulty of the operation and the amount of bleeding. Laparoscopic radical prostate cancer surgery can be completed with only 3~4 small holes, which is easy to reveal under the laparoscope, clear surgical field, less bleeding and fast recovery after surgery. Laparoscopic surgery time is significantly shorter than open surgery.
