DISORDERS OF THE TESTIS & SCROTUM Flashcards
Undescended testes or absent testes (agenesis)
CRYPTORCHIDISM
- occurs when one or both of testicles fail to move down into scrotal sac
- usually unilateral, but can be bilateral (10-20% of cases)
Incidence of cryptorchidism is directly related to (2)
⦁ birth weight
⦁ gestational age
premies are at increased risk
The cause of cryptorchidism in full term infants is poorly understood
- 3-5% of full term infants are born with undescended testicles: Most cases are
idiopathic, but some may be hormonal or genetic
Testes develop intra-_____________ in fetus
abdominally
testes usually descend into scrotum through inguinal canal during ___________ month of gestation
7th - 9th
Most common location for undescended testicle =
High scrotal (60%)
High scrotal (60%) > inguinal canal > abdominal
physical exam of cryptorchidism
the scrotal sac is empty;
the testes is either not palpable, or it can be felt externally to the inguinal ring
Spontaneous testicular descent often occurs during
*Spontaneous descent often occurs during the first 3 months of life so if pt is less than 3 months, tell parents to wait. if still hasn’t descended, will surgically correct
- pathological changes to undescended testicle can occur at
6-12 months
⦁ delay in germ cell development
⦁ changes in spermatic tubules
⦁ reduced number of Leydig cells (release testosterone)
- When the disorder is unilateral, it may also produce morphologic changes in the contralateral descended testicle
When the disorder is unilateral, it may also produce morphologic changes in the
contralateral descended testicle
CONSEQUENCES OF CRYPTORCHIDISM
⦁ Infertility
⦁ Malignancy
Infertility - because of decreased sperm counts & poorer quality sperm. Bilateral cryptorchidism increases chances of infertility
In order for proper sperm production, testes need to be kept below body temp. Also produce testosterone, so if undescended = not only poor quality sperm/low sperm count, but also may lack secondary sex characteristics
Malignancy = increased risk of testicular cancer
- testes hasn’t been able to properly develop –> can lead to abnormal cell development
EXAM TO CHECK FOR UNDESCENDED TESTES
- need to differentiate undescended testes from retractable testes
⦁ use cremasteric muscle reflex –> will retract into inguinal canal (brush inner thigh - and testes will retract on that side)- genitofemoral & ileoinguinal nerve are what control this reflex
⦁ testes are usually palpable at birth
⦁ careful palpation in a warm room can bring them down; if an infant is crying/stressed, testes will retract (normal)
⦁ Testes usually assume a scrotal position during puberty
even once the testes have descended back down into scrotum or once laparoscopy was done to correct it, there is STILL an increased risk for developing
testicular cancer
DIAGNOSTIC TESTING FOR CRYPTORCHIDISM
- diagnostics are usually not needed - can diagnose based on PE
- occasionally an ultrasound is done (if not descended by 3 months, and still not by 6 months)
- Laparoscopy for diagnosis & treatment ( refer to urology for this)
treatment for cryptorchidism
orchiopexy
fixation of testes in the scrotum
- this procedure should be considered before 6 months of life, as the rate of descent diminishes considerably after this point
⦁ 95% of orchiopexy patients will be fertile
is hormone therapy used to help descend the testes?
NO
Hormone therapy with hCG or LHRH no longer considered useful in helping the testes descend
(was causing a lot of other problems)
follow ups in cryptorchidism
- have life-long follow ups due to infertility issues & testicular cancer issues
- Upon reaching puberty, instruct boys of the necessity of self testicular exams (monthly!)
excess fluid collects between the layers of the tunica vaginalis
hydrocele
hydrocele = excess fluid collects between the layers of the
tunica vaginalis
hydrocele is usually due to
weakness in the patent process vaginalis
TYPES OF HYDROCELES
⦁ non-communicating = testes seals off after filling up, no fluid can enter or leave, but build up of fluid remains in testes
⦁ communicating hydrocele = most common = continuous draining into scrotal layer; can lead to a hernia
⦁ Hydrocele of the cord = swelling in scrotum intself, but also have a hydrocele higher up in the spermatocord
most common type of hydrocele
communicating
PRIMARY CONGENITAL HYDROCELE
- seen in male infants & children
- associated with indirect inguinal hernia
- infant hydroceles usually close spontaneously**
- if persists beyond 2 years of age = need surgical treatment
In infants, give them time for hydrocele to heal on its own - body should absorb the fluid; if past 2 years old = surgery
PRIMARY CONGENITAL HYDROCELE = associated with
indirect inguinal hernia
infant hydroceles
usually close spontaneously**
- if persists beyond 2 years of age = need surgical treatment
secondary causes of hydroceles
⦁ trauma
⦁ epididymitis
⦁ testicular torsion
⦁ orchitis
DIAGNOSIS OF HYDROCELE
TRANSILLUMINATION
- shine a light through scrotum to visualize internal structures. If it shines through = fluid present
If light doesn’t shine through, and just shows up as a pinpoint of light against the skin = solid mass
- can also do an Ultrasound:
⦁ if cannot transilluminate
⦁ or if trying to determine underlying conditions in non-neonates
HYDROCELES IN YOUNG MEN VS ADULT MEN
o If a hydrocele develops in a young man without apparent cause = it should be considered cancer until proven otherwise!! Careful evaluation to exclude cancer or infection
o In an adult male, hydroceles are relatively benign conditions; are often asymptomatic, and just have a feeling of heaviness in the scrotum. May have pain in the lower back***
hydroceles in adult men = often asymptomatic or have a feeling of heaviness in scrotum
If symptomatic = may have
pain in lower back
