siehe auchThe fossa navicularis refers to a normal mild dilatation of the urethra. It occurs at the most distal/downstream portion of the urethra.
It is more evident in males, where it occurs in the penile/pendulous urethra, near the urethral meatus. There is also a fossa navicularis in women: the more flexible segment of the urethra between the rigid incisura intermuscularis and the collagenous meatus.
The fossa navicularis is where the balloon is positioned during a retrograde / ascending urethrogram (RUG/ASU).
This fossa navicularis of the urethra should not be confused for the bony defect in the clivus of the same name: fossa navicularis.
