Testicular rupture
70-80% of all inflammatory cases that causes sudden, acute pain.
What is the most common age for testicular torsion?
12-18 years old,.. 13 is peak
What causes the abnormal suspension of the testes within the scrotum?
Testicular torsion
When is immediate surgery needed for torsion? When does incomplete infarction occur?
80-100% salvagable at 4-6 hours; after 12 hours get complete infarction
48X more likely to undergo a malignant change.
Undescended testicle

(and 10X more likely to torse)
When is the testes hyperechoic with torsion? What type of flow results?
Within the 1st 4 hours; absence of flow in testis and epididymis
Acute Torsion has what type of scrotal wall?
Normal scrotal wall,

thick wall with chronic
within 72 hours its 90% salvagable, after 72h it's 45% or ess.
Testicular Rupture
When is the testis hypoechoic with torsion?
After 1st 4 hours
bacterial infection with an unknown cause from UTI, trauma, or STD.
Causes increased vascularity, hypoechoic epi, and thick epi wall.
Due to untreated epididymitis
Can create a hematocele, blood in testicle & irregular capsule.
Testicular Rupture
What are the 4 types of scrotal masses?
Hydrocele, spermatocele,
Testicular hernia, Variocele
