What are the symptoms of ureteral injury?

summary

Ureter is a long and thin tubular organ composed of muscle and mucous membrane. It is located in the retroperitoneal space. It has good protection and considerable range of motion. Therefore, ureteral injury caused by external violence (except penetrating injury) is rare; However, ureteral injury is often caused by ureteral examination and extensive pelvic surgery. What are the symptoms of ureteral injury? Let's talk about it

What are the symptoms of ureteral injury?

Hematuria is common in ureteral mucosa injury caused by instruments. Generally, hematuria will relieve and disappear by itself. If the ureter is completely broken, there may not be urine overflow. Therefore, the severity of the injury is not consistent with the degree of ureteral injury.

It may occur at the beginning of the injury, or at 4-5 days after the injury, delayed urinary extravasation may occur due to the necrosis of the ureteral wall caused by blood supply disturbance (occlusion, ligation or ischemia after adventitia stripping). Urine extravasates from the ureteral injury to the retroperitoneal space, causing local swelling and pain, abdominal distension, muscle spasm and obvious tenderness. If the peritoneum is ruptured, urine may leak into the abdominal cavity, causing peritoneal irritation. Once secondary infection, sepsis can occur, such as shivering, high fever.

Ureteral ligation and suture can cause complete obstruction. Due to the increased pressure of renal pelvis, there may be distending pain in the affected side of the waist, lumbar muscle tension, percussion pain in the renal area and fever. If the isolated kidney or bilateral ureters are ligated, anuria may occur. Ureteral stricture can lead to incomplete obstruction, waist pain and fever.
