OBJECTIVE: To compare the prostatic resistive index (RI) and measurements from pressure-flow studies (PFS) for the diagnosis and follow-up of @entity1876 ( @entity1876 ) in @entity1 with @entity1067 ( @entity1067 ). @entity1 AND METHODS: In all, 338 @entity1 (aged 55-82  years) presenting with lower urinary tract symptoms were evaluated prospectively for @entity1876 secondary to @entity1067 . In all @entity1 , the prostatic RI was measured by transrectal power Doppler ultrasonography. PFS were assessed in all @entity1 and depending on the results the @entity1 were divided into an obstructive and an unobstructive group. The receiver operating characteristic (ROC) curve was used to determine the prostatic RI threshold value for predicting @entity1876 secondary to @entity1067 . @entity1 who were confirmed to have @entity1876 secondary to @entity1067 received either medical or surgical treatment, and they were re-evaluated after 3 and 6  months with prostatic RI measurements. RESULTS: According to the PFS the obstructive group included 158 @entity1 and the unobstructive group 180 @entity1 . The mean (SD) prostatic RI was significantly higher in the obstructive group, at 0.73 (0.04), than in the unobstructive group, 0.65 (0.05) (P  <  0.001). Using the ROC curve a prostatic RI of       0.71 predicted @entity1876 secondary to @entity1067 , with 84.6% sensitivity, 78.4% specificity and 83.8% overall predictability. After management, the prostatic RI of the obstructive group, 0.69 (0.08), was significantly lower than before treatment, 0.73 (0.04) (P  <  0.05). CONCLUSIONS: The prostatic RI can predict @entity1876 with high specificity and sensitivity. We believe that the prostatic RI could be a useful variable for the diagnosis and follow-up of @entity1 with @entity1067 .

The value of measuring the prostatic resistive index vs. pressure-flow studies in the diagnosis of XXXX caused by @entity1067 .
