Initial diagnosis of urethral stricture was based on anamnesis, uroflowmetry and VCUG. Additional imaging procedures\u2014SUG and MRU were performed before the surgery. Virtual models and 3D printed models of the urethra with the stricture were created based on the MRU data. Exact stricture length and location were evaluated by each radiological method and accuracy was verified intraoperatively. Agreement between SUG and MRU assessments of spongiofibrosis was evaluated. MRU images were independently interpreted by two radiologists (MRU 1, MRU 2) and rater reliability was calculated.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>MRU was the most accurate [(95% CI 0.786\u20130.882), <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0005] with an average overestimation of 1.145\u00a0mm (MRU 1) and 0.727\u00a0mm (MRU 2) as compared with the operative measure. VCUG was less accurate [(95% CI 0.536\u20130.769), <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0005] with an average underestimation of 1.509\u00a0mm as compared with operative measure.

SUG and MRU provide extra guidance in preoperative planning and should be considered as supplemental for diagnosing urethral stricture. Combination of VCUG and SUG may be an optimal set of radiological tools for diagnosing patients with urethral strictures located in the penile urethra. MRU is the most accurate method and should particularly be considered in cases of post-traumatic or multiple strictures and strictures located in the posterior urethra.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s11255-021-02994-5","type":"journal-article","created":{"date-parts":[[2021,10,2]],"date-time":"2021-10-02T03:37:34Z","timestamp":1633145854000},"page":"2423-2435","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Retrograde urethrography, sonouretrography and magnetic resonance urethrography in evaluation of male urethral strictures.
