Laparoscopic techniques have now become the mainstay of urological organ resection and reconstruction surgery. As technology advances and people’s quality of life demands improve, surgeons are constantly exploring more aesthetic and minimally invasive ways to treat disease. Since Rane reported the world’s first single-port laparoscopic nephrectomy at the World Congress of Endovenous Urology in Mexico in 2007, the procedure has rapidly become a new technical highlight in urology and has received widespread attention from urologists at home and abroad. A large number of related technical studies and case reports have been published in high-level international conferences and specialized urology journals, such as the 2008~2010 American Congress of Urology, the World Congress of Endovenous Urology, and the European Congress of Urology. Transumbilical single-port laparoscopic technique has the following advantages: (1) a single small incision, which is less traumatic, less painful, enables patients to get out of bed early, early recovery, reduces hospitalization time and cost, accelerates bed turnover, and makes full use of resources; (2) thin and soft umbilical skin, which is lightly tied to the trocar, and flexible in surgical operation; (3) good blood supply to the umbilicus, easy to close the incision with exact sutures, good healing, not easy to be infected, and low incidence of incisional hernia; (4) low incisional scar in the umbilicus. Low incidence of incisional hernia; ④The umbilical incisional scar is inconspicuous and hidden, which combines minimally invasive and cosmetic while achieving lighter postoperative pain and faster postoperative recovery. Therefore, transumbilical single-port laparoscopic technique has become a hot issue of widespread interest in the field of urology. However, single-port laparoscopic techniques have not been widely used in China and Asia, mainly because of the following reasons: 1. Equipment problems: single-port laparoscopic techniques require special single-port laparoscopic channels (R-port, Uni-X, Triport), which are all single-use devices, mostly not formally registered and sold in China. The Triport system platform from Olympus is approved for use in China, which has more components and complex construction, and problems such as air leakage, obstructed access to instruments, and poor visualization often occur in early applications. Its price is high, it can only be used once, and it must be equipped with a special integrated 5mm laparoscopic device and a special bendable single-hole laparoscopic operating instrument. 2, technical problems: single-hole laparoscopic surgery through the umbilical approach is different from conventional laparoscopic surgery, all operations are carried out through a small hole in the umbilicus, the laparoscope and various instruments almost parallel into the abdominal cavity, can not form a triangle in the abdominal cavity, not conducive to the exposure of the organ pull, surgical operation lacks a satisfactory “three-dimensional sense, sense of space”. Single-port laparoscopic surgery is difficult to perform, and the indications are strict. It is difficult for beginners to quickly grasp the technical skills, and the growth period is long, and the risk of clinical practice is very high. Since 2010, based on the accumulated experience of laparoscopic surgery via the transabdominal route, our department carried out transumbilical single-port laparoscopic surgery earlier in China with the application of a homemade single-port device. The single-port puncture cannula was placed into the abdominal cavity under direct vision through the paramedian incision, and the outer diameter was sutured to the skin with two stitches for fixation, and then the laparoscope and surgical instruments were placed for operation. Laparoscopic radical resection of the bladder and prostate, radical resection of kidney cancer, nephrectomy for non-functioning fluid, resection of adrenal masses, and decompression of renal cysts have been performed. The postoperative incision was significantly more beautiful than that of conventional laparoscopic surgery, and there were no complications such as hematoma, infection, intestinal obstruction, or incisional hernia, and no abnormal sensation in the ipsilateral lower abdomen. The follow-up results showed that the technique was safe, feasible, minimally invasive and effective. Transumbilical single-port laparoscopic surgery is suitable for aesthetic patients, especially women. Our homemade single-port device is easy to make and does not increase the cost to the patient, so it is worth promoting its use in China. The successful completion of this type of single-port laparoscopic surgery marks that the laparoscopic surgery technology in the Department of Urology of Peking University Third Hospital is close to the international leading level and represents the development direction of new urological technology. Olympus Triport Single-port transumbilical laparoscopic radical nephrectomy for kidney cancer Single-port laparoscopic radical nephrectomy for kidney cancer Post-operative incision for traditional posterior laparoscopic radical nephrectomy for kidney cancer 8 cases of transumbilical single-port radical cystectomy, 10 cases of radical nephrectomy for kidney cancer, 2 cases of nephrectomy for non-functional hydronephrosis, 1 case of adrenal mass resection, and 6 cases of renal cyst decompression have been completed successfully, without All of them were completed successfully, and there were no cases of open abdomen. The operating time was 40-240 min, the bleeding volume was 10-200 ml, the pathological results were consistent with the preoperative diagnosis, and there were no complications such as hematoma, infection, intestinal obstruction, incisional hernia, etc. There was no recurrence in the postoperative follow-up of 1-12 months. (1) The research related to this technique, “Comparison of the technical characteristics of transumbilical single-port and posterior laparoscopic radical nephrectomy for kidney cancer”, was presented at the 2010 Xi’an National Urology Annual Meeting in the laparoscopic venue. (3) gave a lecture on “radical treatment of renal cancer via umbilical single-port laparoscopy” at the 2010 National Urological Laparoscopy Course of our hospital; (4) gave a lecture on radical treatment of renal cancer via umbilical single-port laparoscopy at the 2010 National Urology Training Week for Directors of Urology Departments held in our hospital. (5) He gave a surgical demonstration of transumbilical uniportal laparoscopic radical treatment of renal cancer and taught the related courses in the seminar on uniportal laparoscopy held by 301 Hospital in December 2010; (6) He gave a conference presentation on “transumbilical uniportal laparoscopic radical treatment of renal cancer” in the annual meeting of Beijing Urological Surgery in December 2010. We are working hard to provide the best service to our patients through our courses and publications. We are trying to popularize this technique in China by means of seminars, publications, and presentations at various conferences.
