In a male, they develop into a system of connected organs between the efferent ducts of the testis and the prostate, namely the epididymis, the vas deferens, and the seminal vesicle. The prostate forms from the urogenital sinus and the efferent ducts form from the mesonephric tubules .
Seminal vesicles seen on an MRI scan through the pelvis. The large cyan-coloured area is the bladder, and the lobulated smaller structures below it are the vesicles. Seminal vesicles seen in a cadaveric specimen from on top, with the bladder to the bottom of the image, and the rectum at the top.
The kidneys are easily examined, and most pathological changes in the kidneys are distinguishable with ultrasound. US is an accessible, versatile inexpensive and fast aid for decision-making in patients with renal symptoms and for guidance in renal intervention. [1] Renal ultrasound (US) is a common examination, which has been performed for ...
Attempts are sometimes made to diagnose an ejaculatory duct obstruction by means of medical imaging, e.g. transrectal ultrasound or MRI, [3] or by transrectal needle-aspiration of the seminal vesicles. However, transrectal ultrasound has a relatively low sensitivity of approx. 50% and thus is only a tool to rule-out cysts in the region of the ...
There are two main populations of CAVD; the larger group is associated with cystic fibrosis and occurs because of a mutation in the CFTR gene, [4] [5] while the smaller group (estimated between 10 and 40%) is associated with unilateral renal agenesis (URA). The mutational spectrum of CFTR in the first group differs from that observed in classic ...
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.
Below this are a number of small glands secreting components of the seminal fluid. The final portion of the duct also receives ducts from the kidneys in most species. [21] In amniotes (mammals, birds, and reptiles), the archinephric duct has become a true vas deferens, and is used only for conducting sperm, never urine. As in cartilaginous fish ...
The kidney function can also be assessed with medical imaging. Some forms of imaging, such as kidney ultrasound or CT scans, may assess kidney function by indicating chronic disease that can impact function, by showing a small or shrivelled kidney. [citation needed].
