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.
Remnants of the paramesonephric ducts can also be found in the prostatic utricle, an expansion of the prostatic urethra at the center of the seminal colliculus. AMH receptor-type II (AMHR-II), also known as Misr-II, causes AMH to act indirectly on mesenchymal cells surrounding the paramesonephric ducts rather than acting directly on the ...
Abdominal ultrasound examination of the prostate and kidneys is often performed to rule out hydronephrosis and hydroureter. Incidentally, cysts, tumours, and stones may be found on ultrasound. Post-void residual volume of more than 100 ml may indicate significant obstruction. [52] Prostate size of 30 cc or more indicates enlargement of the ...
The prostatic urethra, the widest and most dilatable part of the urethra canal, is about 3 cm long.. It runs almost vertically through the prostate from its base to its apex, lying nearer its anterior than its posterior surface; the form of the canal is spindle-shaped, being wider in the middle than at either extremity, and narrowest below, where it joins the membranous portion.
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).
The prostate is an accessory gland of the male reproductive system and a muscle-driven mechanical switch between ... such as ultrasound or MRI. [2] [5] Name Fraction ...
Screening MRI may be performed when there is a positive prostate-specific antigen on basic laboratory tests. Prostate cancer is the second-most common cause of cancer-related mortality in males in the USA. Most species of placental mammals have bulbourethral glands, but they are absent in Caniformia and Cetacea.
There are several reasons why PIN is the most likely prostate cancer precursor. [3] PIN is more common in men with prostate cancer. High grade PIN can be found in 85 to 100% of radical prostatectomy specimens, [4] nearby or even in connection with prostate cancer. It tends to occur in the peripheral zone of the prostate.
