034 Penile blood flow assessment using Doppler ultrasonography (PDUS) in Erectile dysfunction patients: A 10-Year Experiences at an International Hospital in Southeast Asia

Abstract

To demonstrate A 10-year experiences of the penile blood flow assessment using Doppler ultrasonography (PDUS) in Erectile dysfunction patients at an International Hospital in Southeast Asia. A total of 226 patients with ED underwent a penile Doppler examination to exclude nonvascular causes of ED during year 2007-2016. Forty-nine percentage of patients received 10 μg of intracavernosal prostaglandin E-1 and measurements were performed at 5 and 15 min after injection to determine the Peak Systolic Velocity (PSV, cm/s), End Diastolic Velocity (EDV, cm per second), and Resistance index (RI). Erectile dysfunction from vascular cause was determined to be vascular in origin if PSV was < 35 cm/s or RI was < 0.9. A mean age and median body mass index of patients underwent a penile Doppler examination was 46.67±13.53 and 26.93 kg/m2 (30.25-24.16), respectively. Most of the patients are diabetic (42.2%). Out of 226 patients,54%, satisfied the criteria of normal finding, 35.4%, arterial insufficiency, 8.4% venous leak, and 0.9% border line, respectively. Bilateral of arterial insufficiency was found in 24.34% and one single side insufficiency in 11%. There was no association between ethnicity and PDUS Results. However, vasculogenic risk factors were age, BMI and Fasting blood sugar. No serious complication after the test was reported. there are 2 cases of prolonged erection after 4 hours of the test.
