Multiparametric MR Urethrography: Dynamic Comprehensive Evaluation of the Male Urethra

Area of Science:

• Urology
• Radiology
• Medical Imaging

Background:

• Male urethral diseases (strictures, trauma, neoplasms) present significant clinical challenges.
• The male urethra's complex anatomy increases susceptibility to injury and strictures.
• Traditional imaging methods have limitations in assessing periurethral tissues.

Purpose of the Study:

• To review the embryology, anatomy, and risk factors of male urethral diseases.
• To discuss imaging modalities for urethral abnormalities, emphasizing MRI.
• To highlight optimal MR urethrography (MRU) techniques and reporting.

Main Methods:

• Review of embryologic and anatomic features of the male urethra.
• Discussion of risk factors for male urethral diseases.
• Emphasis on Magnetic Resonance (MR) urethrography (MRU) as a comprehensive imaging modality.

Main Results:

• MR urethrography (MRU) provides detailed insights into the urethra and periurethral structures.
• MRI is presented as a comprehensive tool for evaluating urethral diseases.
• Optimal MRU protocols and reporting key points are discussed.

Conclusions:

• MR urethrography (MRU) is a valuable noninvasive tool for diagnosing male urethral diseases.
• Understanding urethral anatomy and MRU techniques is crucial for accurate assessment.
• This review aids in the comprehensive evaluation and reporting of urethral abnormalities.
