Comparative Role of Sonourethrography (SUG) and Magnetic Resonance Urethrography (MRU) in Anterior Male Urethral Strictures

Anterior urethral stricture is a common clinical condition encountered in day-to-day urological practice affecting predominantly males. Retrograde urethrography (RGU) is a common investigation done to determine the future course of management. But with increasing use of plastic surgery and other endoscopic procedures, information regarding presence of spongiofibrosis and other associated conditions, in addition to length of stricture is being demanded from radiologist for deciding the mode of management. Sonourethrography (SUG) has started gaining acceptance over RGU in last few decades for determining periurethral spongiofibrosis which at the same time obviates radiation to gonads. In recent years, magnetic resonance urethrography (MRU) has also been advocated for evaluation of anterior urethral strictures due to its excellent soft tissue contrast and lack of operator dependence. Besides, MRU can delineate posterior urethra simultaneously, affecting further management obviating the need for micturating cystourethrogram (MCU). Hence, in this article we evaluate the comparative role of SUG ad MRU in the evaluation of male anterior urethral strictures.
