For a long time, “long incision and large scar” used to be the hallmark of surgery, and some patients were afraid of this and delayed timely treatment. The development of modern medicine has significantly changed the face of surgery. In the field of urology, transurethral lumpectomy surgery for prostate enlargement, bladder tumors and stones has long realized the dream of incisionless surgery. In the last decade or so, rapidly developing laparoscopic techniques have gradually replaced the various open surgeries of the past. This minimally invasive technique extends the surgeon’s eyes and hands to reach various parts of the body, including the retroperitoneum, abdominal cavity and pelvis, through small incisions to perform complex surgical operations. Compared with open surgery, laparoscopic surgery has obvious advantages, such as less trauma, less bleeding, faster postoperative recovery, and shorter hospital stay, while the treatment effect is the same as that of open surgery, so laparoscopic technology is now widely used to treat various diseases in urology. At present, the diseases that can be treated by laparoscopic surgery include: adrenal tumor, retroperitoneal tumor, renal tumor, renal cyst, renal pelvic ureteral tumor, renal pelvic ureteral junction stenosis, ureteral stenosis, bladder tumor, prostate tumor, varicocele, cryptorchidism, vesicovaginal fistula, bladder diverticulum, etc.
