Extravaginal torsion occurs exclusively in newborns. Ultrasound findings include an enlarged heterogeneous testis, ipsilateral hydrocele, thickened scrotal wall and absence of vascular flow in the testis and spermatic cord. The ultrasound findings of intravaginal torsion vary with the duration and the degree of rotation of the spermatic cord.
Testicular torsion may also be caused by trauma to the scrotum or exercise (in particular, bicycle riding); [10] however, only about 4–8% of cases are the result of trauma. [1] [2] There is thought to be a possible genetic basis for predisposition to torsion, based on multiple published reports of familial testicular torsion. [10]
According to Prehn's sign, the physical lifting of the testicles relieves the pain of epididymitis but not pain caused by testicular torsion. [ 4 ] Negative Prehn's sign indicates no pain relief with lifting the affected testicle, which points towards testicular torsion which is a surgical emergency and must be relieved within 6 hours.
Testicular pain may be of sudden onset or of long duration. [1] [2] Causes range from non-serious muscular skeletal problems to emergency conditions such as Fournier gangrene and testicular torsion. The diagnostic approach involves making sure no serious conditions are present. Diagnosis may be supported by ultrasound, urine tests, and blood ...
The cremasteric reflex may be absent with testicular torsion, upper and lower motor neuron disorders, as well as a spine injury of L1-L2. It can also occur if the ilioinguinal nerve has accidentally been cut during a hernia repair. [4] The cremasteric reflex can be helpful in recognizing testicular emergencies.
Partial resection of the hydrocele sac, leaving a margin of 1–2 cm. Care is taken not to injure testicular vessels, epididymis, or ductus deferens. The edge of the hydrocele sac is oversewn for hemostasis ( von Bergmann 's technique) or the edges are sewn together behind the spermatic cord (Winkelmann's or Jaboulay's technique).
testicular microlithiasis on ultrasound. Testicular microlithiasis is an unusual condition diagnosed on testicular ultrasound. It is believed to be found in 0.1–0.6% of males globally, with frequency varying based on geographic location and is more often found in individuals with subfertility.
The exact cause of an epididymal cyst is unknown, but it is most likely a congenital anomaly associated with hormonal imbalances during embryonic life. [3] Previous research has shown a correlation between the development of epididymal cysts and maternal exposure to endocrine disrupting substances like diethylstilbestrol during male fetal development.
