As a result of straddle injury, a patient had rupture of bulbar urethra. He presented with urethral bleeding and swelling in the perineum. All of the following are true regarding his management EXCEPT: March 2013
First, I need to recall the management steps for bulbar urethral injury. Straddle injuries typically affect the bulbar urethra, which is the most common site for such injuries. The initial management usually involves assessing the injury and deciding between conservative or surgical intervention.
Immediate catheterization is tricky here. If there's a complete rupture, inserting a catheter might not be possible or could cause more damage. So maybe the wrong option is about immediate catheterization. Alternatively, surgical repair might be necessary, but timing is important. I remember that in some cases, a suprapubic catheter is placed to drain the bladder while the urethral injury heals. Also, external drainage with a urethral catheter might not be feasible if there's a rupture.
Let me think about the options. The question is from March 2013, so the correct answer is the one that's an exception. The options likely include things like immediate catheterization, suprapubic cystostomy, waiting for spontaneous healing, etc. The incorrect answer would suggest doing something that's contraindicated, like immediate catheterization in a complete rupture.
Wait, in straddle injuries, the management depends on the severity. Partial injuries might allow for catheterization, but complete ruptures usually require surgical repair. So if an option says that immediate catheterization is done in all cases, that's wrong. Alternatively, if an option says that cystoscopy is the first step, that might be incorrect because in complete ruptures, you can't pass a scope. Suprapubic cystostomy is a key step to relieve bladder pressure and allow healing. So the exception would be something that contradicts these steps.
Another point: perineal swelling and bleeding suggest a significant injury. The management would involve surgical exploration if there's active bleeding or signs of a complete tear. So if an option says to wait and see without intervention, that's incorrect. Also, the use of a urinary catheter in such cases is contraindicated if there's a complete rupture because you can't pass it through the urethra. So the wrong option might be about immediate catheterization.
Putting it all together, the correct answer is the one that states immediate catheterization is part of management. The exception here would be if an option claims that immediate catheterization is done, which is incorrect because it's contraindicated in complete ruptures. Therefore, the answer is the option that suggests immediate catheterization.
**Core Concept**
Straddle injuries typically cause bulbar urethral rupture, the most common site of urethral trauma in males. Management hinges on distinguishing partial from complete tears and avoiding urethral manipulation in full-thickness injuries to prevent further damage. Key principles include bladder drainage via suprapubic cystostomy and surgical repair if indicated.
**Why the Correct Answer is Right**
In complete bulbar urethral rupture, **immediate catheterization is contraindicated** due to risk of exacerbating the injury or causing false passages. Instead, **suprapubic cystostomy** is performed to relieve bladder pressure and
