How do you check for urethral injury?
Blood along the perineum or at the meatus, which is the opening of the urethra, are signs of injury. A high-riding prostate gland also may indicate injury to the urethra. A retrograde urethrogram also may be performed. This imagining test is commonly performed to diagnose urethral injury or narrowing.
How do you treat urethral damage?
Treatment of Urethral Injuries For urethral tears, the urine should be diverted from the urethra using a catheter placed directly into the bladder through the skin over the lower abdomen. The urethra is repaired surgically after all other injuries have healed or after 8 to 12 weeks (when inflammation has resolved).
What part of urethra affects surgical trauma?
This type of trauma can lead to scars in the urethra (” urethral stricture”). These scars can slow or block the flow of urine from the penis. Trauma to the posterior urethra almost always results from a severe injury.
Which part of urethra is injured in straddle injury?
The spongy urethra is most likely to be injured with a catheter or in a straddle injury, allowing urine and blood to escape into the scrotum, the penis, and the superficial peritoneal space. Urethral rupture may be diagnosed with a cystourethrogram.
Can urethral stricture heal itself?
Most of the time, it is a permanent cure. We perform a urethroplasty by removing the part of the urethra with the stricture and scar tissue. If it is a long stricture, we may also add new tissue, such as a graft from the mouth (a buccal mucosal graft) or a flap of skin to help reshape urethra.
How long does it take for a minor urethral tear to heal?
Small lacerations will generally heal in three to five days with urinary diversion using an indwelling urethral catheter or cystostomy tube. Larger lacerations will heal if a strip of uroepithelium remains intact but strictures may result.
How long does it take a urethral tear to heal?
Which part of the urethra is most commonly injured?
Mechanisms of Urethral Injury The distal membranous urethra is especially at risk, and its injury may disrupt the active continence mechanism. The most common injury by far is that of the posterior urethra. Such injury occurs in 3%–25% of patients with pelvic fractures (,5) .
Can the urethra be repaired?
Depending on the exact location and the extent of damage, the urethra will be repaired by either replacing the tissue with tissue from another part of the body, or by taking out the damaged portion of the urethra and then reconnecting the urethral tube.
What happens if your urethra is damaged?
If the urethra is injured, a person may develop urethra obstructions or strictures. Urethral strictures occur when the urethra is injured or scarred by an infection and then narrows. As a result, problems with the normal passage of urine and semen can develop.
Where does a traumatic urethral injury take place?
Typical location and appearance of a traumatic urethral injury involving the posterior urethra. This site is susceptible to injury as the puboprostatic ligaments are firmly attached to the base of the prostate at this location and produce a strong shearing force if the pubic bones or pubic symphysis become displaced.
Which is the best radiology test for urethral injury?
Voiding cystourethrography is the most appropriate way to evaluate the posterior part of the male urethra and injuries to the female urethra. Retrograde urethrography is the modality of choice to investigate the anterior part of the urethra. It will demonstrate extraluminal contrast, which has extravasated from the urethra at the site of injury.
Can a traumatic urethral injury cause hematuria?
Clinical presentation. In the setting of trauma, the classic triad of blood of the external urethral meatus or vaginal introitus may be seen but is an unreliable sign, as is hematuria. Inability to void may be seen in complete urethral disruption. Examination may reveal blood on digital rectal exam and perineal ecchymosis.
How is retrograde urethrography used in urethral injury?
Retrograde urethrography is the modality of choice to investigate the anterior part of the urethra. It will demonstrate extraluminal contrast, which has extravasated from the urethra at the site of injury. It is important to determine if this is above the urogenital diaphragm (anterior) or below (posterior) it.
