Reproductive: Miscellaneous Male Flashcards
Calcified vas deferens
Note: Common in diabetic pts.
Calcified vas deferens and seminal vesicles
Note: Common in diabetic pts.
Prostatic utricle cyst
Differential for midline pelvic cyst in a male
- Prostatic utricle cyst
- Müllerian duct cyst
- Ejaculatory duct cyst
Differential for off-midline pelvic cyst in a male
- Seminal vesicle cyst
- Diverticulosis of the ampulla of vas deferens
Male
Seminal vesicle cyst
Note: Off-midline pelvic cyst in a male.
Congenital seminal vesicle cysts are associated with…
- Polycystic kidney disease
- Renal agenesis
- Vas deferens agenesis
- Ectopic ureter insertion
Common causes of acquired seminal vesicle cysts
- Prostatic hypertrophy
- Chronic infection/scarring
Note: Classic history is prior prostate surgery.
Seminal vesicle cyst
Prostatic utricle cyst
Cystic dilatation of the prostatic utricle (a midline structure in the prostatic urethra that is a remnant of the Müllerian duct)
Prostatic utricle cysts are associated with…
- Hypospadias
- Unilateral renal agenesis
- Prune belly syndrome
- Downs syndrome
- Imperforate anus
Retrograde cystourethrogram
Prostatic utricle cyst
Note: Focal posterior outpouching of the prostatic urethra.
Which type of male pelvic cyst communicated with the urethra?
Prostatic utricle cyst
Note: This is why these cysts are at an increased risk for superinfection.
What is the most common association with a prostatic utricle cyst?
Hypospadias (urethral opening along the ventral penis)
Male
Müllerian duct cyst
Note: This is due to failed regression of the caudal ends of the Müllerian ducts (in the region of what would be the cervix/vagina).
Does a Müllerian duct cyst communicate with the urethra?
No
Note: The Müllerian duct cyst is basically a vagina/cervix that failed to fully regress in a male.
Müllerian duct cyst
Note: Prostatic utricle cysts do not extend above the base (superior extent) of the prostate.
How can you tell the difference between a prostatic utricle cyst and a Müllerian duct cyst?
