Pedi GU Conditions Flashcards
(113 cards)
What is Hypospadius?
Urethral opening on ventral surface of penile shaft, foreskin absent ventrally
1/250 newborn males
Complications of Untreated Hypospadius
- Deformity of urinary stream: Ventral deflection or severe splaying
- Sexual dysfunction due to penile curvature
- Infertility if meatus is proximal
- Meatal stenosis (very rare)
Management of hypospadius
- Avoid circumcision -foreskin used for repair
- Refer to pediatric urologist
- Educate parents
- Out-patient surgery ~12 mos
Comfort parents – “not a big deal”
Undescended Testes UDT (Cryptorchidism): when do majority descend and why?
- Majority descend in three months
- Interaction of hormones and mechanical factors
- Usually palpable in inguinal canal
UDT: what to do if testes not palpable?
- maybe intra-abdominal, perineum
- Refer to GU
Consequences of UDT
- Infertility
- Malignancy: hotter in abdominal area
- Associated hernias
- Torsion of undescended testis
- Possible psychological effects of empty scrotum
DDx for UDT
- Retractile testis– physiologic variation of normal
- Overactive cremasteric reflex –sends up. E.g., d/t cold
- Incomplete attachment of testis to scrotum
- Later diagnosis
- Inguinal hernia
should be evaluated if retractile and approaching puberty (may get stuck)
PE for UDT
including what to do if can’t find them
- Warm room, warm hands
- Supine position – better than in parents’ lap
- Inspect scrotum – e.g., femoral pulses – you may see them though they are retracted later in exam
- Sweep hand down – occlude inguinal ring
- Other options:
- squatting
- cross-legged
- standing
- parents attempt in bath tub and follow-up
Mgmt of UDT
- Spontaneous resolution with age
- reflex less active
- testis larger
- Surgical (orchidopexy) 98% success, OP
- Move to normal position
- After 12 mos
- If nonpalable testis, diagnostic laparoscopy (gu referral):
- Maybe bring down,
- Maybe remove if atrophic or abnormal
- May be completely absent
What is a Hydrocele?
Collection of peritoneal fluid in scrotum from different mechanisms
What is a communicating hydrocele?
- Process vaginalis NOT obliterated (should close during fetal dvpt)
- Little opening – fluid can squeak down through. Be on lookout for hernia as well as time goes on
Communicating hydrocele: Sx, PE, Px
- May increase or decrease during day ask parents
- Cystic scrotal mass with transillumination
- Sometimes need Doppler to be sure
- If congenital, resolve by 1 yr., if not surgery
Noncommunicating hydrocele: what is it?
- No connection to peritoneum
- Fluid from lining of tunica vaginitis
Noncommunicating hydrocele: presentation and cause
- Does not change – important difference
- Maybe idiopathic or secondary to other causes
mgmt of hydrocele
- Explain condition to parents
- Alert to higher risk for hernia
- If large and tense, needs referral
- too hard to verify no hernia
- large hydroceles don’t resolve spontaneously
Inguinal hermia: who gets them and where?
- 10-20/1000 live births; 50% < 12 mos
- Boys: girls - 4:1
- 60% on right side
- 30% on left side
- 10% bilateral
- Premature infants -30% higher incidence
Very common in premies – watch for it!
What is an inguinal hernia?
- Persistent patency of process vaginalis → Protrusion of peritoneum into the inguinal canal
- Usually pv fuse and obliterate entrance to inguinal canal
- If not, then inguinal anomalies
inguinal hernia - no mass
what is the hx and urgency?
history of intermittent bulge (fairly nonurgent)
inguinal hernia - reducible mass
what is the hx and urgency?
usually no symptoms, maybe irritability, decreased po, not tender
inguinal hernia - nonreducible mass
what is the hx and urgency?
incarceration. Irritable, crying, vomiting, distention, tenderness – abdominal contents stuck in scrotum
inguinal hernia - strangulation
what is the hx and urgency?
- vascular compromise of contents of hernia from edema and vascular obstruction maybe 2 hrs…!! Medical emergency!
MGMT of inguinal hernia
- IF intermittent mass – you’re comfortable it’s only intermittent
- Refer for repair electively after diagnosis (few weeks)
- IF
- Not easily reducible
- Painful, firm mass
- Refer immediately for repair
- Exploration of contralateral side due to high incidence of bilateral hernias-controversial
Hydrocele vs Hernia - how to tell
- May be difficult to distinguish
- Complete hernia and hydrocele may both transilluminate
- “Silk sign” -If spermatic cord feels like silk, hernia likely – Difficult in infants; not good evidence for effectiveness
- mass in inguinal canal – make sure it’s not testicle. If it’s not, you could refer. If intermittent, easily reducible, not an emergency. If constant/irreducible – get it checked!*
- Incarceration: urologist asap; strangulation: ER*
What is Phimosis?
- Unretractable foreskin in uncircumcised boys
