Injury - kidney and ureter

Alternative Names:

Kidney damage; Toxic injury of the kidney; Kidney injury; Traumatic injury of the kidney; Fractured kidney; Inflammatory injury of the kidney; Bruised kidney; Ureteral injury
Treatment:

Treatment goals include treatment of emergency symptoms and prevention or treatment of complications. Most cases of external trauma result in mild bruises that heal spontaneously.

Analgesics may be needed for pain relief. Hospitalization and close observation may be required because of the risk of internal loss of blood from a traumatically injured kidney.

Approximately 20% of cases of external damage require emergency surgery because of bleeding problems. Bleeding may be severe enough to require surgical removal of the entire kidney (nephrectomy) to control the bleeding. Surgical interventions to control bleeding may include drainage of the space around the kidney. Sometimes angio-embolization is utilized to stop the bleeding.

Surgical repair of a "fractured" or torn kidney, torn blood vessels, torn ureter, or similar injury may spare the kidney from removal. The timing of the surgical exploration depends on the location, the extent of injury, and the overall clinical situation.

For example, if an isolated ureteral injury is discoved a week later, a clinician may divert the urine with the nephrostomy tube, let the inflammation settle down, and elect to operate at a later date for the definitive treatment.

The kidney may return to normal function, or it may experience acute or chronic failure. If only one kidney is affected, there may be no symptoms from the failed kidney, because the second (healthy) kidney functions normally and is adequate for normal health.

Surgical removal or repair of clots or other obstructions may correct injury caused by damage to blood vessels or the ureter.

Nonsurgical treatment of external damage to the kidney may include bedrest for 1 to 2 weeks or until bleeding is reduced, narcotics for pain relief, and close observation and treatment for symptoms of kidney failure.

Exposure to substances, including medications that are suspected of causing injury to the kidney, should be stopped. This may require stopping or changing medications, or it may require a change in occupational or recreational habits. Many cases of toxic injury will reverse when exposure to the substance is stopped.
