I have completed laparoscopic pyeloplasty, ureteral anastomosis, ureteral bladder reimplantation and other ureteroplasty nearly 30 cases, I feel that the advantages of laparoscopy to do this type of surgery is more obvious, mainly reflected in: 1, trauma is small, the effect of the body surface cosmetic good, fast recovery; 2, the more main performance in the amplification of the role of laparoscopy can be done to achieve the margins of the suture, the distance between the stitches, such as more neat, of course, need to be operated by laparoscopic technology! The laparoscopic operation technique is of course required to pass the test. Overall laparoscopy to do this kind of surgery operation time is generally a little longer than the open surgery time, with the increase in the number of cases of surgery, the operation time will be gradually close to the individual that is not the main problem. After all, more precise and less invasive surgery is the real embodiment of the progress of surgical technology.
