Torsion
❏ two types: torsion of appendices or testicles1. Torsion of the appendices2. Testicular torsion (spermatic cord torsion)

Torsion of the appendices
❏ twisting of testicular/ epididymal vestigial appendix ❏ often < 16 years of age ❏ signs and symptoms• clinically similar to testicular torsion• "blue dot sign" - blue infarcted appendage seen through scrotal skin (can usually be palpated as small, tender lump)• point tenderness over the superior-posterior portion of testicle
❏ treatment• analgesia - most will subside over 5-7 days• surgical exploration and excision if diagnosis uncertain or refractory pain

Testicular torsion (spermatic cord torsion)
❏ testis rotates from within outwards causing strangulation of the blood supply ––> ultimately leads to necrosis of entire gonad if untreated within 5-6 hours
❏ possible at any age, but most common in adolescence (12-18 years) due to pubertal increase in testicular volume
❏ incidence• ~1/4000, males < 25 years

Testicular torsion (spermatic cord torsion)
❏ predisposing factors• cryptorchid testis• trauma (although 50% occur during sleep)• bell clapper congenital deformity:
• narrow mesenteric attachment from cord on to testis/epididymis – –> testis falls forward and is free to rotate within tunica vaginalis
• anomalous development of tunica vaginalis or spermatic cord

Testicular torsion (spermatic cord torsion)
❏ signs and symptoms• acute onset of severe scrotal pain, swelling +/- nausea/vomiting• retracted and transverse testicle (horizontal lie)• no pain relief with testicle elevation (negative Prehn’s sign)• epididymis may be palpated anteriorly in the early stages

Testicular torsion (spermatic cord torsion)
❏ diagnosis• ultrasound with colour-flow Doppler probe over testicular artery (if torsion, no blood flow)• decrease uptake on 99M Tc-pertechnetate scintillation scan• examination under anesthesia and surgical exploration

Testicular torsion (spermatic cord torsion)
❏ treatment• emergency detorsion (rotate "outward") +/– elective bilateral
orchidopexy• failure of manual detorsion requires surgical detorsion and bilateral orchidopexy (fixation)• < 12 hours - good prognosis• 12-24 hours - uncertain prognosis, testicular atrophy• > 24 hours - poor prognosis, orchiectomy is advised

Epididymitis
❏ etiology• infection
• < 35 years - gonorrhea or Chlamydia (STDs)• > 35 years - coliforms (from GI tract)
• prior instrumentation• reflux
• increased pressure in prostatic urethra (straining, voiding, heavy lifting)causes reflux of urine along vas deferens ––> sterile
epididymitis

Epididymitis
❏ signs and symptoms• sudden onset scrotal pain and swelling +/– radiation along cord to flank• scrotal erythema and tenderness• fever• irritative voiding symptoms• reactive hydrocele, epididymo-orchitis

Epididymitis
❏ diagnosis• urinalysis (pyuria), urine C&S• +/– urethral discharge: Gram stain for gram-negative cocci or rods• pain may be relieved with elevation of testicles (Prehn’s sign), absent in
testicular torsion• if diagnosis clinically uncertain, must do
• colour-flow Doppler ultrasound• nuclear medicine scan• examination under anesthesia (EUA)
