A penile doppler ultrasound is a useful tool in determining the cause and extent of erectile dysfunction (ED) and Peyronie’s disease. Testing can determine whether ED is happening as a result of a lack of blood flow to the penis, or an unwanted loss of blood flow from the penis. With this information, it is easier to pinpoint whether a patient is having trouble getting or keeping an erection, and predict the success rate of particular treatments. An ultrasound can also be used to investigate scarring that causes Peyronie’s disease. Book a consultation with Dr. Kuan to see if a penile doppler ultrasound can help you discover the best treatment plan for your ED or Peyronie’s disease.
