Q

should providers perform U/S or other imaging prior to referral for cryptorchidism according to AUA guidelines?

A

NO!!!

Providers shouldn’t perform US or other imaging studies in the evaluation of boys with cryptorchidism prior to referral as these studies rarely assist in decision making

Q

if pt has unilateral or bilateral cryptorchidism w/hypospadias or bilateral non-palpable testes, what’s that work-up?

A
  • CONSULT!!!
  • Sex (need to know if it’s a boy or a girl)

25
non-comunicating hydrocele d/t?
d/t minor trauma, inflammatory conditions acute reactive hydrocele: -epididymitis, testicular torsion, varicocele operation, testicular tumor PROCESSUS VAGINALIS OPENS AND CLOSES IN THIS ONE
26
communicating hydroceles d/t to? discovered when? occur following?
Usually discovered in infancy Due to patent processus vaginalis (STAYS OPEN ALL THE TIME) Occur following increased intra-abdominal fluid or pressure - Due to shunts, peritoneal dialysis, or ascites - Likely from an imbalance of secretion and reabsorption of fluid from the tunica vaginalis
27
what pts have a high risk of communicating hydroceles?
pts with connective tissue disorders
28
signs and sx's of hydrocele?
painless scrotal swelling
29
physical exam of hydrocele?
***transillumination to assess for fluid - if get glow, then there is fluid = hydrocele palpate for masses differentiate from hematocele, hernia, or solid mass
30
hydrocele evaluation?
scrotal U/S | -to evaluate for reactive hydrocele due to testicular neoplasm or other etiology
31
tx for idiopathic hydroceles?
Often asymptomatic or with only scrotal swelling Observation - surgical treatment only if increased pressure, pain, or chronic irritation of scrotal skin
32
tx for communicating hydrocele?
Due to patent processus vaginalis -> ***requires surgical closure (similar to hernia surgery)
33
what is a varicocele? caused by?
cystic testicular mass of varicose veins caused by dilation of pampiniform plexus
34
what side is most common for varicocele?
Left side!!!
35
b/c varicocele is d/t dilation of pampiniform plexus, what can occur with pt if have this?
Pampiniform plexus maintains specific temperature for sperm production -> can result in testicular growth retardation during puberty
36
how many grades of varicoceles?
3
37
grade 1 varicocele
small - palpable only w/valsalva
38
grade 2 varicocele
medium - palpable at rest -> invisible
39
grade 3 varicocele
large - easily visible
40
M/C sign of varicocele?
scrotal mass feels like BAG OF WORMS!!! -> disappears in supine position
41
physical exam for varicocele?
- Fullness, usually in spermatic cord - Bag of worms - Should be examined in upright position, in a warm room
42
dx for varicocele?
scrotal U/S Left testicular venogram
43
if child has right-sided varicocele (or bilateral), what could be the cause?
a retroperitoneal mass
44
what is the main reason to treat a varicocele?
b/c can cause infertility
45
when is tx recommended for varicocele?
Varicocele is palpable on physical exam of the scrotum (may be d/t retroperitoneal mass if on right side or bilateral) Couple has known infertility Female partner has normal fertility or a potentially treble cause of infertility Male partner has abnormal semen parameter or abnormal results from sperm function tests
46
tx for varicocele?
embolization
47
what is hypospadias? caused by?
abnormal urethral placement (subcoronal, mid shaft, penoscrotal) Caused by failure of fusion of the urethral folds, endodermal differentiation, and ectodermal ingrowth in gestational weeks 8-20
48
hypospadias is one of the most common what?
one of the most common birth defects
49
hypospadias risk factor?
low birth weight
50
hypospadias tx?
- Maybe nothing - Don't circumcise Surgical - short procedure that's same day - 6-12 months old, but can be done anytime - May need testosterone pretreatment
51
what is phimosis? can be normal up to?
The foreskin cannot be fully retracted over the glans penis Foreskin fused to the gland at birth and not retractable Can be normal up to adolescence
52
causes of phimosis?
- The tip of the foreskin is too narrow to pass over the glans penis - The inner surface of the foreskin is fused with the glans penis - The frenulum is too short to allow complete retraction -> frenulum breve - Pathological if difficulty urinating or associated with abnormal sexual function
53
tx for phimosis?
Steroid creams (not recommended by Coops) Manual stretching (overtime will pull it back) Changing masturbation habits (slow down - going too fast is a common cause of paraphimosis) Preputioplasty Circumcision -M/C reason to do a circumcision in an adult (usually b/c can't keep it clean)
54
what is the M/C reason to do a circumcision in an adult?
phimosis tx
55
what is paraphimosis?
Foreskin of the penis once pull back behind the glands -> cannot be retracted back -> ischemia to gland of penis Foreskin starts to swell -> cuts off blood supply to corona of penis -> if stays this way cuses gangrene of the penis
56
is paraphimosis an emergency?
YES!!! it's a urological emergency!!!
57
who does paraphimosis only occurs in?
Occurs only in uncircumcised or partially circumcised males
58
what else can lead to the same pathophysiological derangements as seen with paraphimosis?
External objects may constrict the mid to distal shaft | ex: string, metal rings, rubber rings
59
who is at an increased risk of paraphimosis?
uncircumcised people
60
signs and sx's of paraphimosis?
- Penile pain - Swelling/enlargement - Congestion with edematous foreskin - Discoloration - N/V in adults If prolonged ischemia -> severe paraphimosis -> distal penis has begun the process of autoamputation In peds -> may manifest as acute urinary tract obstruction -> obstructive voiding symptoms
61
paraphimosis tx?
Conservative therapy initially with gentle retraction of foreskin -If that doesn't work, then do circumcision Severe paraphimosis refractory to conservative therapy -> bedside emergency dorsal slit procedure to save penis Circumcision can be performed in the operating room at a later date -> Ultimate tx
62
what is the ultimate tx of paraphimosis?
circumcision
63
if pt has severe paraphimosis refractory to conservative therapy, what's the tx?
bedside emergency dorsal slit procedure to save penis
