To estimate the capabilities of a developed complex of pulse sequences (PSs) for magnetic resonance imaging (MRI) to diagnose male urethral diseases. The results of MRI, X-ray contrast retrograde urethrography (RUG), and voiding cystourethrography (VCUG) were analyzed in 46 patients of different ages who were treated for suspected urethral pathology at the Urology Unit, Rostov State Medical University Clinic. An algorithm is proposed for tomographic examination of the male lower urinary tract, which involves patient preparation and positioning, a list of PSs and the order of their use, and their parameters. The MRI semiotics of urethral stricture disease is described. There is information on the clinical application of MRI in urologic practice, which is compared with the results of other medical imaging and the data of surgical intervention and histological examination of the material obtained. Along with the known advantages of MRI over other radiation techniques, the complex of PSs proposed to study the male urethra surpasses conventional X-ray contrast RUG and VCUG in diagnostic informative value. This MRI technology can reliably identify and accurately locate stricture or obliteration of the urethra in its all portions and determine the extent and degree of abnormal urethral narrowing, as well as provides a way of estimating the extent of fibrous changes in the spongy body.
