To provide a concise step-by-step approach to magnetic resonance urethrography (MRU) with focus on technical aspects of the study, proper patient preparation and structured report.

To provide information on basic imaging anatomy of the urethra in MRU.

MRU is an emerging and more frequently applied tool for evaluation of the urethra as an alternative to traditional radiographic methods such as retrograde urethrography (RUG) and voiding cystourethrography. MRU is especially useful in cases of post-traumatic or multiple strictures and strictures located in the posterior urethra. It provides information of the utmost significance for therapy/preoperative planning such as location and length of the stricture, presence and degree of spongiofibrosis as well as associated periurethral pathologies.

A step-by-step brief guide through magnetic resonance urethrography:

1. Exclusion of all generally known contra-indications to magnetic resonance imaging (MRI) and application of gadolinium based contrast agents.
2. Informed consent to be obtained from the patient....read more

Magnetic resonance urethrography should gain recognition in current imaging algorithms of urethra. Data provided by MRU enables precise preoperative planning and thus benefits both the surgeons and patients. The conditions of correct interpretation of obtained images are the knowledge of radiological anatomy, proper preparation of the patient prior to examination as well as application of tailored imaging protocol.
