Abstract:
PURPOSE: To investigate whether the result of RigiScan after intracorporeal injection could predict the result of duplex ultrasonography, and determine the necessity of duplex ultrasonography. MATERIALS AND METHODS: We performed both RigiScan and duplex ultrasonography after intracorporeal injection in 18 men with erectile dysfunction. All of the patients were evaluated by history taking, physical examination, laboratory test, hormonal tests, and neurologic examination before RigiScan and duplex ultrasonography. We measured maximal arterial diameter, peak systolic velocity, end-diastolic velocity using a 7 MHz. color Doppler unit and these results of duplex ultrasonography were compared with penile rigidity and tumescence measured by RigiScan. RESULTS: The positive and negative predictive value of RigiScan were 81.8% and 85.7%, respectively. The result of RigiScan was comparable with that of duplex ultrasonography and the accuracy of RigiScan was resonable. CONCLUSIONS: According to this results, duplex ultrasonography was needed if the response of RigiScan is abnormal after intracorporeal injection. However, duplex ultrasonography can be ommitted if the response of RigiScan is normal after intracorporeal injection.
