With the use of single-port laparoscopic surgical technique for radical kidney cancer by Professor Zhang Xu, a renowned urological laparoscopist in China, in July 2009, the exploration of minimally invasive urological laparoscopic techniques has taken another big step forward in China. In the past 20 years, what we are familiar with is standard laparoscopic surgery, that is, placing trocars (5, 10 or 12 mm in diameter) in multiple skin incisions and arranging them in a triangular shape to facilitate the operation. With the development of minimally invasive techniques, minimizing surgical trauma and increasing cosmetic results has become the direction of surgical development. The methods currently being explored to reduce surgical trauma include needle laparoscopy, NOTES surgery (endoscopic surgery through the natural lumen) and SPL surgery (single-port laparoscopic surgery). I) Needle laparoscopy: It is characterized by the use of 2mm needle laparoscopic instruments to complete the procedure without skin incision during trocar puncture and without postoperative sutures, resulting in little surgical scarring and associated postoperative pain. (B) NOTES surgery: The surgery is performed by puncturing the natural cavity of the patient’s stomach, vagina, bladder, colon, esophagus, etc. to enter the body. The result is a scarless and minimally invasive body surface. However, special bendable instruments are required. These instruments are expensive and difficult to operate. It is easy to produce illusion, and once the gastric, intestinal or urinary fluid leaks into the abdominal cavity, it is easy to cause serious sideburns. (C) SPL surgery: Hasson method is used to establish a pneumoperitoneum and then a 2.5 cm “Z” shaped incision around the umbilicus is made and TriPort (which is a special device for SPL evolved from hand-assisted laparoscopic access. It allows tight fixation of the abdominal wall. The entire system is flexible and allows easy insertion of curved or articulated laparoscopic instruments. Therefore, there is only one scar at the umbilicus. A better cosmetic result is achieved. However, in terms of surgery, SPL surgery has not yet reached the level of standard laparoscopic operation. The next step needs to be the development of bendable manipulators, high brightness, high resolution endoscopes and greater freedom of access.
