Non-Neoplastic Male GU - Fremont-Smith Flashcards
(48 cards)
embryo of male
not on exam
phimosis
cannot retract foreskin over penis
congenital and acquired
acquired - recurrent infection uncircumcised adult males
hypospadias
more common
opening bottom of penis
epispadias
rare**
opening top of penis
associated with bladder exstrophy**
undescended testicles
cryptorchidism
usually before 6 months old
hydrocele
fluid collection around teste
-usually resolve spontaneously
transillumination
firm nontender testicle with discoloration
testicular torsion - prenatal
foreskin
in newborn - tight and adherent
white sebaceous cyst at tip - normal
paraphimosis
excessive retraction of foreskin
-CANNOT be returned to normal
strangulation of venous flow
physiologic phimosis
congenital
-resolves with age
adhesions epithelial layer of skin
acquired phimosis
pathologic
secondary - balantic, malignancy, etc.
poor hygiene
forceful retraction
tx phimosis
weak topical corticosteroid cream
surgery
circumcision - only permanent cure
smegma
extruded as part of normal separation process of glans penis and foreskin
majority of penile conditions
traumatic
swelling of penis and penile pain
paraphimosis
urinary obstruction
need to reduce paraphimosis
cause of hypospadias
unknown
possible hormonal imbalance
as hypospadias go further down shaft
more complications
extrophy of bladder
failure of cloacal membrane development
bladder connects to surface
requires surgical repair
with epispadias
testicular descent
form in abdomen - urogenital ridge
coelomic cavity envaginates through abdomen wall to scrotal swelling
over time testis drawn in processus vaginalis (coelomic cavity) pulled by caudal genital ligament
descent into scrotum - guided by gubernaculum - forms inguinal canal
processus vaginalis - obliterates after birth
testes and spermatic cord descend
lining of peritoneum
to scrotal sac
-communication with peritoneum
muscles of inguinal canal
form direct path for descent to occur
- over time - muscles overlap
- less communication with peritoneum
will obliterate eventually
hydrocele
communicating or non-communicating
communicating - sac communicates with peritoneal fluid**
- can be narrow or wide
- can reduce sac - push fluid up
non-communicating - with partial obstruction
communicating hydrocele
bulging scrotal mass in infant
normal and common
with increased intraabdominal pressure - pushes fluid into scrotum
more common right**
