What is ureterosigmoid anastomosis?

summary

Anastomotic leakage of urine is mainly caused by ureteral blood flow disorder and improper suture. According to the severity of urinary leakage, decisive measures (such as abdominal drainage, ureterostomy and the application of a large number of antibiotics) must be taken to save the patient's life. What is ureterosigmoid anastomosis? Now let me tell you something.

What is ureterosigmoid anastomosis?

After the ureter was separated and cut into the abdominal cavity, the small intestine was covered, blocked and pushed away with gauze pad. The retroperitoneum in front of the ureter was cut to expose the ureter, and the distal ureter was ligated at the lowest position of the pelvic ureter or at an appropriate distance from the lesion. A ureteral catheter was inserted into the proximal ureter to drain urine temporarily to reduce abdominal contamination

The proximal ureter should be repaired to separate the proximal ureter, but the tissue around the ureter should not be completely stripped, so as not to affect the blood supply. The tissue around the proximal end of the ureter should be dissected and cut 1.5cm longitudinally, and then the orifice of the ureter should be made into an elliptical inclined plane, so that the anastomotic orifice can be expanded three times and the drainage is unobstructed.

Anastomosis of the ureterosigmoid colon a small incision was made at the bottom of the seromuscular layer of the sigmoid colon, which was equal to the elliptical section of the ureteral end. The two incisions were aligned for end-to-side anastomosis. At first, the upper and lower corners of the whole layer of the ureter and the edge of the mucosal layer of the intestinal wall were sutured with 4-0 chromium gut thread, and then 8-10 interrupted sutures were made. After suturing the retroperitoneum, the medial edge of the retroperitoneal incision was sutured to the outside of the anastomosis line, and then the lateral retroperitoneum was sutured to the inside of the anastomosis line, so that the anastomosis was located outside the peritoneum again

matters needing attention

Patients must go to large hospitals for regular treatment, must actively cooperate with the doctor's treatment, usually must pay attention to personal hygiene, pay attention to rest, don't be too nervous, try not to eat spicy food, can eat more fresh fruits and vegetables.
