When it comes to pediatric laparoscopy, many parents and even doctors and nurses equate it with inguinal hernia and appendicitis, but that’s wrong! Do you know which departments in China have done the most clinical procedures after the introduction of “robots” into hospitals? Urology and Obstetrics and Gynecology are in the lead! Does laparoscopy only allow you to perform surgery on your stomach? Wrong! In the Department of Urology of Zhejiang University Children’s Hospital, apart from the regular hole in the stomach for kidney ureteral surgery, we can also make a hole in the waist and do minimally invasive surgery of kidney ureteral adrenal in the retroperitoneal space; we can also make a hole in the bladder for minimally invasive surgery of ureteral bladder. In recent years, with the development of technology, minimally invasive laparoscopic surgery can be done for diseases that previously required open surgery, such as hydronephrosis, heavy kidney, giant ureter, and vesicoureteral reflux. In the past, it took 2 weeks to be hospitalized for hydrocele surgery, but now it only takes about 1 week. In the past, the scar was 3.4 centimeters, but now there are only a few holes, with beautiful appearance, fast recovery and good efficacy, which has won praise from parents of children and domestic counterparts. Because it does not enter the abdominal cavity, there is little interference with the intestines and abdominal organs, and the damage is light, so the postoperative recovery is faster. Because the retroperitoneal space is a potentially relatively small space, which is difficult to locate and has poor anatomical markings, the technical requirements are very high, so few children’s hospitals in China carry out the procedure. The team of Shan Xu/ Guangjie Chen has dedicated themselves to research and has successfully performed renal cyst decortication, nephrectomy, renal tumor resection, and adrenal tumor resection. Especially for adrenal tumor surgery, because of the deep location and difficult exposure, open surgery usually requires a large incision, long operation time and great patient injury, which, can all be perfectly solved with the posterior laparoscopic technique.
