Correct Answer » A
Explanation
|
|
A i.e. MRI
The anterior urethra extends from the external urethral meatus to the distal membranous urethra, including the penile and bulbar urethra.
– Strictures in this area are generally investigated with imaging modalities that delineate the lumen and surrounding tissue as well as functional assessment when needed.
Clinical Reasoning for the Correct Answer:
– MRI is not commonly used for routine evaluation of anterior urethral strictures due to cost, availability, and limited advantage over established methods.
– MRI may demonstrate soft tissue details but lacks real-time visualization of urethral lumen and functional obstruction assessment compared to other modalities.
– It is rarely indicated unless complex periurethral pathology or malignancy is suspected.
