Abstract:
Presentation of the first study on the diagnostic efficacy in the study of stenosis with ultrasound urethrography (U.U.) as compared to X-ray retrograde urethrography (X.R.U.). Sensitivity of U.U. in anterior bulbar urethra is, in general, higher than that of X.R.U. (100 U.U. > 88 X.R.U.) while X.R.U. specificity is higher in the posterior bulbar urethra (100 X.R.U. > 97 U.U.). In penile urethra both techniques showed a 100% diagnostic efficacy. Stenosis located in the posterior bulbar urethra are the most difficult to diagnose with ultrasound techniques.
