Cavernosography: indications, technique of execution, transcript
Basically, to correctly diagnose erectile dysfunction, a carefully collected history and examination of the patient.However, in some cases, more detailed diagnostics are required.This will provide an opportunity to collect more information, which in turn will make treatment as effective as possible.
Cavernosography is an X-ray study, during which a X-ray contrast medium is injected through a small needle into the cavernous bodies of the penis. With this method, the doctor assesses the condition of the blood vessels of the penis.
Important! Cavernosography is a mandatory study to exclude or confirm the vascular nature of erectile dysfunction.
The study is used in complex cases.It makes it possible to distinguish venous occlusion and arterial inflow deficiency, as well as to determine the place of venous blood discharge into the arterial bed of the penis.
Technique for performing
In the cavernous bodies of the penis, an X-ray contrast medium is injected( Omnipac, Ultravist, Urografine, etc.).Prior to the procedure, intravenous injection of a test dose of 1 ml is made to detect an allergic reaction to the contrast drug.In the absence of allergies, a full dose of 20 ml is administered and X-rays are sequentially performed on the 1st, 3rd, 10th, 15th and 25th minute.
Important! No special training is required before carrying out the study.
Indications for carrying out the cavernosography
The diagnostic method allows:
- reveal pathological venous outflow in venous erectile dysfunction;
- to assess the structural changes in cavernous bodies, as well as to identify the presence of foci of atrophy and sclerosis in them.Identify plaques in Peyronie's disease;
- determine the proportions of the legs and trunk of the penis when deciding whether to corrugate the legs with erectile dysfunction of mixed genesis;
- to reveal the places of rupture in the cavernous body, which arose as a result of injuries to the penis.
Before the procedure, 10 μg of prostaglandin E1 can be injected into the penis to induce an erection.If a quarter of an hour after the introduction of the drug in the patient does not have an erection - this indicates the presence of organic erectile dysfunction.
Cases when it is not recommended to perform a cavernosography:
- Bronchial asthma of severe form.
- Acute inflammation of the urogenital system.
- Allergy to iodine-containing drugs.
- urethrocavernous fistula.
- Diseases in which blood clotting is impaired.
After carrying out a cavernosography, an aseptic bandage is applied to the genital and bed rest is recommended for two hours.
