Recently, the Department of Urology of our hospital successfully completed another case of radical surgery for posterior laparoscopic anatomical kidney cancer. Patient Liang, male, 44 years old. During the hematological physical examination, the color ultrasound revealed a large 7 cm tumor growing in the upper pole of the left kidney. After coming to our urology department for hospitalization, the diagnosis of left renal cell carcinoma was confirmed after a comprehensive and meticulous examination. After thorough preoperative discussion, it was decided to perform posterior laparoscopic anatomical radical kidney cancer surgery for him, and a safe and feasible treatment plan was formulated. The surgery took about 3 hours to enucleate and the procedure was very smooth. Since it was a minimally invasive retroperitoneal surgery, the patient was able to eat the next day, leave the bed on the third day, and was discharged from the hospital one week after the operation. In traditional radical kidney cancer surgery, not only a large incision of 20 cm to 30 cm has to be made in the patient’s waist or abdomen, but also various layers of abdominal muscles have to be incised layer by layer in order to completely remove the affected kidney and its surrounding tissues, which is very traumatic, bleeding and takes a long time to recover in bed. In contrast, posterior laparoscopic radical kidney cancer surgery only opens three small 1-2 cm channels in the patient’s waist to perform the operation, and then removes the specimen through a small 5 cm incision, which has the advantages of minimally invasive, less bleeding, no need to cut abdominal muscles, mild postoperative pain and fast recovery. Liang was discharged from the hospital in only 12 days and had no discomfort at the time of discharge. Minimally invasive laparoscopic surgery is an inevitable trend in the future development of surgical methodology. Laparoscopic surgery has the following advantages compared with traditional surgery: 1. Quick recovery and short hospitalization time after surgery. Semi-liquid food can be eaten the next day after surgery, and normal life and work can be resumed after one week. 2. High quality of life. Traditional surgery scars are longer, laparoscopic surgery incisions are hidden, do not leave obvious scars, local aesthetics. 3, laparoscopic camera has a magnifying effect, can clearly display the fine structure of the body tissue, compared with traditional open surgery, the field of view is clearer, so the operation is more accurate, fine, effectively avoid unnecessary interference with the organs outside the operating site, and less intraoperative bleeding, surgery is safer. 4, surgical trauma Small, light postoperative pain. Generally, patients do not need to use pain treatment after surgery. At present, minimally invasive luminal surgery in our urology department has accounted for about 70%-80% of all surgeries. In addition to posterior laparoscopic radical nephrectomy for kidney cancer, we are also capable of performing posterior laparoscopic renal cyst debulking, posterior laparoscopic adrenal tumor resection, posterior laparoscopic total adrenalectomy, posterior laparoscopic ureterotomy for stone extraction, posterior laparoscopic partial nephrectomy, high ligation of spermatic vein and other laparoscopic surgeries.
