1. Audiovisual Sexual Stimulation (ASS): Audiovisual Sexual Stimulation (ASS):
Monitor the penis under the sexual stimulation of the viewing behavior.This can be closer to the physiological state to understand the ability of the penis, but it often needs to conduct comprehensive analysis and judgment with NPT monitoring.
2. Economic nerve detection:
Nerves have an important role in the erectile mechanism. Therefore, conventional testing and erectile nervous systems are related to the cause of the cause of the cause, especially patients with skull, spinal cord, pelvic trauma, and history of diabetes.
Bulbocavernosusususus Reflex Latenecy IME (BCRL): detect the penis back nerve (sensing) to the ingot.Speed, normal should be 27-42ms.
3. Psychological and psychological test:
Many Peninusida's individual survey forms (MMPI), Derogatis sexual function survey forms, and California's personalized survey forms have reference value for identifying psychological and organic erectile dysfunction, but cannot be used as an important basis.
4. NOCTURNAL PENILE TUMEScence (NPT):
In 1970, Karacan first used the physiological phenomenon of natural erection of the night penis to identify psychological and organic yang fistula.This test is less affected by psychological factors and can objectively reflect the function of penile erection.When normal people are fasting sleep, the penis erection is 4 to 6 times a night, which lasts for 25-40 minutes.Rigiscan monitored 65%to 70%, but this test was still 15%to 20%of false negatives.
5. Penile blood flow test:
Penile vascular lesions are an important cause of organic erectile dysfunction, that is, the imbalance of arterial blood supply disorders and venous closure mechanisms.
Vascular active drugs induce erectile tests: At present, poppy alkali is mostly 30 to 60mg, phenol vanadium has 1 to 2 mg or prostinine E20 & Mu; G, separate or combined application.Injecting the drug into the sponge body, the penis can reach a rigid erection and maintain it for more than 30 minutes, indicating that there is no significant vascular lesion, but there is still possibility of false negativeness.It is supplemented by sexual stimulation after injection, and its reliability is higher.Essence, hematoma and complications may occur.
Penis Doppler ultrasound monitoring: Measure the penile arterial blood pressure to the epidemic (PBI).Smaller than 0.6 indicates that penile arterial blood supply disorders are prompted.The difference between the absolute value of the two systolic blood pressure should not exceed 4KPa (30mmHg).
Penile Flow Index (PFI): The Doppler ultrasonic probe is used to measure the radial artery, penile back and sponge arterial acceleration.PFI <6 suggests that penile blood is normal.
Penile arterial bloodstemia diameter question record: Normal penile bloodstemia vein capacity waveform rose rapidly to the top of the peak and then slowly decreased.The circular peak top may be reduced and the two -wave vein cutting disappears, indicating that there is vascular lesions.
Color duplex Doppler ultrasound testing: detecting sponge structure, internal diameter, blood flow speed and blood vessels, and can dynamically detect the changes in penile artery, vein blood flow dynamic changes, sponge resistance index, etc. during the erectile process.One of the most valuable non -damage examination methods with vascular erectile dysfunction.
Sponge infusion test and sponge body angiography Injecting the sponge in 30 secondsPressure Loss (PL).The greater the MF and PL values, the function of venous leakage erectile dysfunction.Normal PL should be <3.3kPa (25mmHg) within 30 seconds, MF should be <20 ~ 40ml/min, and the IF should be 80 ～ 120ml/min.The sponge body radiography is to observe whether there are abnormal vein return during an injecting agent in injection. Several abnormal reflux is: deep veins on the back of the penis to the prostate and intra -pussy veins, cavernous veins to prostate, intraocular veins, penis sponge sponge sponge sponge sponge sponge sponge sponge sponge sponge sponge sponge sponge sponge sponge sponge spongeBetween body and urethral sponge leakage.
Internal arterial angiography: Those who are suspected of penile arterial blood supply disorders shall, before the reconstruction of penile arteries, shall be carried out by the femoral arterial bilateral endure arteries to observe the two penile back arteries and sponge arteries.
