Penile blood flow index

The penile flow index (PFI) is a non-invasive method for determining the blood supply state of the penis. PFI <6 is generally considered to indicate normal penile blood vessels. If PFI > 6, angiography will show the lesion. The closer the occlusive lesion is to the penile arteriole, the greater the PFI value. The day before the physical examination should pay attention to rest, avoid strenuous exercise and emotional excitement, and ensure adequate sleep, so as not to affect the physical examination results. It is best to take a bath. Basic Information Specialist classification: male examination inspection classification: other inspection Applicable gender: whether the male is fasting: not fasting Tips: Pay attention to rest before the physical examination, avoid strenuous exercise and emotional excitement, and ensure adequate sleep, so as not to affect the results of physical examination. Normal value PFI <6, suggesting that the penile blood vessels are normal. Clinical significance Abnormal results If PFI > 6, angiography will show the lesion. The closer the occlusive lesion is to the penile arteriole, the greater the PFI value. People who need to be examined: patients with sexual dysfunction. High results may be diseases: sexual aversion, yang, non-organic libido, loss of libido Points to note before checking: 1. The subject needs to make an appointment to operate; 2. Before the examination, explain to the doctor the usual erectile function and ejaculation latency; 3, a few days before the physical examination, pay attention to diet, do not eat too much greasy, not easy to digest food, do not drink alcohol, do not eat drugs that damage liver and kidney function; 4, the day before the physical examination should pay attention to rest, avoid strenuous exercise and emotional excitement, to ensure adequate sleep, so as not to affect the results of physical examination. It is best to take a bath. Requirements for inspection: 1. Don't be shy and nervous when checking, to avoid blood flow acceleration and affect the test results. 2, when lying on the tester should be lying flat, do not move randomly when checking. 3. Actively cooperate with physicians and care for instruments. Inspection process The paralyzed patient lies flat on the detector, and sends an ultrasonic wave to the human blood vessel through the ultrasonic probe. The echo signal is received by the probe to obtain the average flow velocity of the blood flow, and the corpus cavernosum artery is detected, and the penile blood flow index is automatically calculated by the computer. (PFI value) to determine whether sexual dysfunction is caused by vascular lesions. It can also be used to detect systolic and diastolic blood pressure. Not suitable for the crowd A patient with a damaged penis. Adverse reactions and risks Damage to the vessel wall (rare), swelling, bleeding, or infection at the insertion site, and an allergic reaction to the contrast agent.
