investigations
Last reviewed 01/2018
Patients should be inquired about:
- timing of onset and progression of pain
- history of trauma
- aggravating and alleviating factors
- associated genitourinary and systemic symptoms (1)
Physical examination should include:
- position of the swelling in relation to the scrotum (1)
- consistency of the swelling – fluctuant (hydrocele, spermatocele) or firm ( cancer) (2)
- transillumination – to separate hernia from spermatocele or hydrocele (2)
Few investigations are helpful in the decision-making process. Consider:
- FBC - may help to identify cause of lymphadenopathy
- ultrasound scan - may aid in confirming the presence of a testicular mass and to examine the contralateral testis (3) - however referral is thought to be mandatory in such cases (4). An urgent ultrasound scan should be arranged in the following patients:
- scrotal mass that does not transilluminate and/or when the body of the testis cannot be distinguished (5)
- in patients with retroperitoneal or visceral masses without a palpable testicular mass (3)
Sensitivity of detecting a testicular cancer is almost 100% with an ultrasound scan (3).
