How big does urinary stone need operation

First, surgery can be considered. Looking for ureter during operation is something that should be noticed during operation. It is also a difficult point to make sure that your disease is not infectious. When the retroperitoneal cavity is dilated by water sac, the upper third of ureter can be seen. When dilating, the peritoneum is separated from psoas major muscle slowly. Psoas major muscle should look for the inside. It is not difficult to find the stone by making full use of the preoperative surface positioning of the stone, insertion of ureteral catheter, intraoperative fluoroscopy and other auxiliary methods.

Second: due to the inconvenience of laparoscopic operation, it is important to understand the severity of the disease. Ureterotomy is more difficult, scissors are not easy to cut ureter, even if the cut ureter incision is not neat or parallel with ureter, which leads to difficult suture, easy to cause urinary leakage, ureteral stenosis and other complications. Ureterotomy with electric knife and laser often leads to postoperative ureteral stricture due to its thermal effect.

Third: the inflammation around the ureter is serious, and it is difficult to expand. We should also consider it under normal circumstances. We should take some medicine to control the disease first. Laparoscopy through abdominal cavity can be considered. If there is a history of intra-abdominal infection or surgery, it is better not to choose transabdominal approach, but to consider retroperitoneal approach.

Ureteral catheter can be placed under laparoscope, which is rarely seen in general. Do not let the development of the disease be controlled as far as possible. After the renal pelvis was pushed upward to prove patency, double-J tube was replaced and placed in ureter to prevent postoperative leakage or stricture.
