Penile Ultrasound

High-resolution real-time gray-scale ultrasound and color Doppler flow imaging (CDI) technology can be used for the examination of various diseases of the penis. At present, CDI has become an important detection method for the diagnosis and differential diagnosis of vascular impotence. Basic Information Specialist classification: male examination inspection classification: ultrasound Applicable gender: whether the male is fasting: not fasting Tips: After applying the coupling agent to the probe, cover the probe with a plastic film. If necessary, the surgeon also needs to wear disposable latex gloves. Normal value Normal image of the penis: 1. The longitudinal section of the urethra has a thin line of lower-level echoes located in the urethral sponge. 2. The longitudinal section of the sponge is a strip-like structure with a well-defined boundary, and the interior is a medium-level uniform point-like echo. The long axis of the deep penile artery is parallel with a thin line of high echo, showing the clearest erection. Clinical significance Modern two-dimensional ultrasound and CDFI (color Doppler flow imaging) are important imaging diagnostic methods for the detection of impotence in impotence. Routine ultrasound examination of the penis (see above) contributes to the diagnosis of impotence caused by certain organic lesions, CDFI and spectral blood flow examination, combined with dilated vascular drug-induced erection test, to determine the quality of the instrument due to hemodynamic changes The diagnosis of sexual impotence is helpful. Among them, arterial insufficiency impotence accounts for about 30%, venous is about 15%, and mixedness accounts for about 55%. 1, posterior urethra stones, stenosis, congenital urethral valve and so on. 2, penile trauma. 3. Ultrasound evaluation of impotence. Precautions 1. The clinic should be quiet and dark, reducing onlookers. 2. After applying the coupling agent to the probe, cover the probe with a plastic film. If necessary, the surgeon also needs to wear disposable latex gloves to prevent probe contamination and cross infection. Inspection process Ultrasonography. Not suitable for the crowd Old people who are physically weak and inconvenient to move. Adverse reactions and risks Generally no complications occur.
