Following trauma, a patient presents with a drop of blood at the tip of urinary meatus. He complains of inability to pass urine. Next step should be:
**Core Concept:** Urinary retention and hematuria after trauma are clinical scenarios involving urinary system dysfunction.
**Why the Correct Answer is Right:** In this scenario, the correct answer is **A** (Urinary catheterization) because it is the most appropriate method to assess the patient's urinary function and manage the obstruction caused by trauma. Urinary catheterization allows for proper urine output and evaluation of the bladder's ability to empty effectively.
**Why Each Wrong Option is Incorrect:**
**Option B:** Performing a cystoscopy is not the best choice since it is an invasive procedure that should be reserved for cases where the cause of the problem is unclear after catheterization.
**Option C:** Urethral suction diathermy is not the correct choice because it is an invasive procedure that may cause further trauma, worsening the patient's condition.
**Option D:** Intravenous pyelography (IVP) is not relevant in this scenario as it is an imaging study used to visualize kidney, ureters, and bladder. In this case, we need to directly assess the patient's urinary function, which catheterization provides.
**Clinical Pearl / High-Yield Fact:** Urinary retention post-trauma is a common condition that can lead to complications such as renal insufficiency, urinary tract infections, and bladder spasms. Early recognition and management are crucial to prevent these complications and ensure proper patient care.

**Question:** Following trauma, a patient presents with a drop of blood at the tip of the urinary meatus and complains of inability to pass urine. The next step should be:
A. Urinary catheterization
B. Cystoscopy
C. Urethral suction diathermy
D. Intravenous pyelography
**Correct Answer:** A. Urinary catheterization

**Core Concept:** Urinary retention and hematuria after trauma are clinical scenarios involving issues with the urinary system.
**Why the Correct Answer is Right:** Urinary catheterization is the appropriate next step as it allows for the assessment of the patient's urinary function and helps to evaluate the bladder's ability to empty properly. This procedure can prevent potential complications such as renal insufficiency, urinary tract infections, and bladder spasms associated with retention.
**Why Each Wrong Option is Incorrect:**
**Option B:** Cystoscopy is an invasive procedure that involves visualizing the bladder via a cystoscope. While useful, it does not directly assess the patient's urinary function and may not address the patient's symptoms effectively.
**Option C:** Urethral suction diathermy is an invasive procedure used for treating enlarged prostate or other bladder conditions. In this scenario, it is not the best approach to address the patient's symptoms and complications associated with retention.
**Option D:** Intravenous pyelography is an imaging study used to visualize the kidneys, ureters, and bladder. It does not directly address the patient's symptoms and complications of retention. Urinary catheterization provides a more direct approach to assess the patient's urinary function.
