RENAL AND GENITOURINARY
EMERGENCIES
SYMPTOMS/EXAM
■ Hallmark is asymptomatictesticular mass, firmness, or induration.
■ Exam may show scrotal swelling or a palpable mass.
DIAGNOSIS
■ Ultrasound can confirm the presence of a mass.
TREATMENT
■ Urgent urologic referral
Appendageal Torsion
The testicle has four appendages. Torsion of the appendix testis(90%) and
theappendix epididymis(8%) account for virtually all cases of appendageal
torsion. The appendix testis attaches to the upper pole of the testes and the
appendix epididymis to the head of the epididymis. Appendageal torsion is
most frequently seen in preadolescent boys.
SYMPTOMS
■ Acute onset of scrotal pain with a discrete painful testicular or epididymal mass
■ Less commonly, associated with nausea/vomiting, dysuria, urgency, or
frequency
EXAM
■ Tender and discrete scrotal “nodule”
■ Blue-black dot when present with transillumination of the testicle (blue-
dot sign) is pathognomonic (see Figure 18.8).
DIAGNOSIS
■ Primarily clinical
■ Doppler ultrasound and radionuclide scanning that illustrates decreased
blood flow to the appendage
Painless testicular mass =
cancer until proven otherwise.
“Blue-dot sign” with
transillumination of scrotal
skin = appendageal torsion.
