ABSTRACT
To determine the treatment method of urethral strictures the most important is location, length, number of strictures, as well as the etiology of the disease. Currently, there are several methods to diagnose urethral strictures. The most common ways to visualize the urethra are retrograde and voiding urethracystography. It is known that urethrogrphy conducted in an oblique projection may lead to underestimation of the true extent of bulbo-membranous urethra stricture. The best way to visualize proximal urethra is voiding urethrography allowed to define the proximal border of the restriction and its functional significance. Ultrasonography allows to identify the length of bulbar urethra stricture with greater precision. CT and MRI play an important but limited role in the diagnosis of urethral stricture, as their information content does not exceed a simple and affordable techniques. The significance of these methods is reduced with the diagnosis of pelvic fracture, revealing the displacement of the prostate and the presence of intrapelvic hematoma in patients with post-traumatic urethral injury. At all times it is better to define the method of treatment in the preoperative phase, rather than to take emergency decision during the operation. The review deals with the definition of the diagnostic value of different methods.
