The seminal colliculus (Latin colliculus seminalis), or verumontanum, of the prostatic urethra is a landmark near the entrance of the seminal vesicles. Verumontanum is translated from Latin to mean 'mountain ridge', a reference to the distinctive median elevation of urothelium that characterizes the landmark on magnified views. Embryologically, it is derived from the uterovaginal primordium. The landmark is important in classification of several urethral developmental disorders. The margins of seminal colliculus are the following:

the orifices of the prostatic utricle
the slit-like openings of the ejaculatory ducts.
the openings of the prostatic ducts

Posterior urethral valves

The verumontanum is an important anatomic landmark for pathology in a congenital anomaly known as posterior urethral valves, in which there is a developmental obstruction of the urethra in newborn male infants.^[1] Urethral carcinoid tumors have been reported at the verumontanum.^[2] The structure tends to migrate caudally, or downward, in hypospadia disorders and is then seen in the bulbous, or penile portion of the urethra.^[3]

Prostatic utricle

The prostatic utricle, a mesonephric remnant, arises from the urethra at the level of the verumontanum and projects posteriorly. This blind ending structure can be associated with hypospadias. This is distinct from a Cowper duct syringocele, which arises at the bulbous urethra.

Several experiments show that prostatic fluid is continuously produced and it is drained from the prostate during urination and ejaculation. The mechanism which causes prostatic fluid to drain from the prostatic acini during urination is currently unclear. Also in current opinion such structures of
