Extravasation of urine

Extravasation of Urine

Extravasation of urine refers to the leakage of urine from the urinary tract into surrounding tissues. This condition can occur due to trauma, surgical complications, or obstruction in the urinary system.

Causes

The primary causes of extravasation of urine include:

• Trauma: Injury to the urinary tract can lead to leakage of urine. This is often seen in cases of pelvic fractures or penetrating injuries.
• Surgical Complications: Procedures involving the bladder, ureters, or urethra can sometimes result in accidental damage, leading to urine leakage.
• Obstruction: Blockages in the urinary tract, such as ureteral stones or strictures, can cause increased pressure and subsequent rupture of the urinary tract.

Symptoms

Symptoms of extravasation of urine may include:

• Pain and swelling in the affected area
• Fever and chills if infection is present
• Decreased urine output
• Abdominal distension

Diagnosis

Diagnosis of extravasation of urine typically involves:

• Physical examination
• Imaging studies such as ultrasound, CT scan, or MRI to visualize the leakage
• Urinalysis to check for signs of infection or blood

Treatment

Treatment options depend on the severity and cause of the extravasation:

• Catheterization to divert urine and allow healing
• Surgical repair of the damaged area
• Antibiotics if infection is present

Complications

Potential complications include:

• Infection
• Abscess formation
• Sepsis

Prevention

Preventive measures include:

• Careful surgical techniques
• Prompt treatment of urinary tract obstructions
• Use of protective gear to prevent trauma
