Commonest late complication of traumatic rupture of urethra is –
**Core Concept**
Traumatic rupture of the urethra is a severe injury that can lead to significant complications if not properly managed. The urethra is a delicate tube that connects the bladder to the outside of the body, and its rupture can cause damage to surrounding tissues and structures.
**Why the Correct Answer is Right**
The commonest late complication of traumatic rupture of the urethra is stricture formation. This occurs when the injured urethra heals with scar tissue, leading to narrowing of the urethral lumen and potentially causing urinary obstruction. The healing process involves the deposition of collagen and other proteins, which can lead to fibrosis and contraction of the urethral wall. This can result in a stricture that may require surgical intervention to restore normal urinary function.
**Why Each Wrong Option is Incorrect**
**Option A:** Urethral fistula is a possible complication of traumatic rupture, but it is not the most common late complication. A fistula is an abnormal connection between two body parts, and in this case, it would be a connection between the urethra and another structure, such as the skin.
**Option B:** Bladder rupture is a possible complication of pelvic trauma, but it is not directly related to urethral rupture.
**Option C:** Erectile dysfunction can be a complication of pelvic trauma, but it is not a direct result of urethral rupture.
**Clinical Pearl / High-Yield Fact**
It is essential to recognize the signs and symptoms of urethral stricture, such as dysuria, urinary retention, and decreased urine flow, to ensure timely diagnosis and treatment.
**Correct Answer:** C.
