Role of Sonourethrogram and Retrograde Urethrogram in the Management of Urethral Strictures

Introduction Sonography has become the urologist& #039, s stethoscope, we evaluated stricture urethra with sonourethrogram and compared sonourethogram to RGU. Objectives of the study To compare the diagnostic accuracy of sonourethrogram and Retrograde Urethrogram. To find out the degree of spongiofibrosis by sonourethrogram. Materials& methods This prospective study was done at Tirunelveli Medical College Hospital. The study period being January 2012- December 2012. After conventional grey scale imaging to evaluate the extent of disease, the location of bulbourethral arteries was evaluated using doppler USG and later compared to their location in men with normal urethra. Results There was not much of a discrepancy between sonourethrogram and RGU. When there was 74 % or more narrowing of urethral lumen outcome of VIU was poor. The degree of spongiofibrosis which could be identified only by sonourethrogram influenced therapeutic decisions. in 7 % of cases Conclusions Sonourethrogram is a very useful modality in the evaluation of anterior urethral strictures. It is superior to retrograde urethrogram in stricture length and spongiofibrosis assessment, which aid in choosing the ideal therapeutic approach.
