Vasography with a prostatic cyst and seminal vesicles filled with iodinated contrast. Vasography is an X-ray study of the vas deferens to see if there is blockage, oftentimes in the context of male infertility. [1] An incision is made in the scrotum, contrast is injected in the vas deferens, and X-rays are taken from different angles. [1]
In addition, if an obstruction of the vasa deferentia is the cause for the azoospermia, the concentration of fructose in the semen will also be normal, since the fructose comes primarily from the fluid stored in the seminal vesicles. If the seminal-vesicles contain spermatozoa, but the semen does not, the obstruction must be downstream of the ...
Absence of fructose may indicate a problem with the seminal vesicles. The semen fructose test checks for the presence of fructose in the seminal fluid. Fructose is normally present in the semen, as it is secreted by the seminal vesicles. The absence of fructose indicates ejaculatory duct obstruction or other pathology. [5]
CT angiography is a contrast CT taken at the location and corresponding phase of the blood vessels of interest, in order to detect vascular diseases. For example, an abdominal aortic angiography is taken in the arterial phase in the abdominal level, and is useful to detect for example aortic dissection. [10]
Inflammation of the seminal vesicles is called seminal vesiculitis and most often is due to bacterial infection as a result of a sexually transmitted infection or following a surgical procedure. Seminal vesiculitis can cause pain in the lower abdomen, scrotum, penis or peritoneum, painful ejaculation, and blood in the semen. It is usually ...
The prostatic utricle (Latin for "small pouch of the prostate") is a small indentation in the prostatic urethra, at the apex of the urethral crest, on the seminal colliculus (verumontanum), laterally flanked by openings of the ejaculatory ducts.
TRUS plays a key role in assessing azoospermia caused by obstruction, and detecting distal CBAVD or anomalies related to obstruction of the ejaculatory duct, such as abnormalities within the duct itself, a median cyst of the prostate (indicating a need for cyst aspiration), or an impairment of the seminal vesicles to become enlarged or emptied. [6]
The seminal colliculus (Latin colliculus seminalis), or verumontanum, of the prostatic urethra is a landmark distal to the entrance of the ejaculatory ducts (on both sides, corresponding vas deferens and seminal vesicle feed into corresponding ejaculatory duct).
