Is prostate resistive index more effective than urodynamy in patients with transurethral prostatectmy

Objective: Benign prostatic hyperplasia is the most common cause of lower urinary tract symptoms in aging men. Urodynamic examination is the gold standart method in evaluating of patients suffering from micturation problems (dysuria, urinary incontinence, neuropathic disorders, and disorders cause lower urinary tract obstruction. Although urodynamic examination is the gold standart method for diagnosis of bladder outlet obstruction not only it is an invasive procedur, but also associated with a small but important risk for significant morbidity such as urinary tract infections. We aimed to assess the use of prostatic resistive index determined by using transrectal ultrasonography for predicting infravesical obstruction as shown by urodynamic study. Material and Method: In this study a total of 40 consecutive men over 50 years who presented between June 2012 and August 2013 to our outpatient department because of lower urinary tract symptoms were included. In addition to the standart urodynamic evaluation the prostatic resistive index was determined in all cases. Local ethics committee approval and written informed consent from all individuals were obtained before the study. Results: The value of prostatic resistive index measurements was not statisticaly different among individuals with or without infravesical obstruction proven by urodynamic study. Conclusions: Our results failed to demontrate the prostatic resistive index as a useful tool for diagnosing bladder outlet obstruction Key words: benign prostatic hyperplasia, urodynamy, resistive index,
