Key Questions in the History

Characteristic of the pain Recurrent pain suggests torsion
History of trauma
History of change in the size of the testicle Changes during Valsalva suggests communicating hydrocoele or varicocele
Sexual history STDs can cause epididymitis
Difficulty voiding urine Suggests intraabdominal mass (hernia), UTI, neurologic problems or spinal cord disease
Flank pain or Hematuria Suggests kidney stone with referred pain to the scrotum
Abdominal pain with diminished appetite, nausea and vomiting Suggests testicular torsion
16
Focused Exam

• Inspection
• Palpation
• Cremasteric Reflex
• Phrens sign
• Blue dot sign

17
Inspection

• Inspect while the patient is standing check the
  penis, pubic hair and inguinal areas.
• Inspect for ulcers, papules, pubic hair
  infestations or lymphadenopathy
• Does the patient have any tattoo? Piercings?

18
Inspection

• The left testicle is slighlty lower than the
  right

19
Palpation

• Roll the testicle between thumb and forefingers
  to look for masses
• Palpate for the epididymis and go up towards the
  spermatic cord.
• Transilluminate the scrotum if swelling is
  suspected.

20
Predicting Testicular Size
21
Cremasteric Reflex

• Stroking the upper thigh results in elevation of
  the ipsilateral testicle.
• Usually present in boys 30 months to 12 years
• Less reliable in teenagers and infants

22
Phrens Sign

• Elevation of the scrotal contents relieves pain
  in patients with epididymitis and not with
  testicular torsion.
• Not a reliable exam in most situations.

23
Blue Dot Sign

• Almost always suggestive of torsion of the
  appendix testis.

24
Additional Tests
Test Purpose
Complete Blood Count Elevated WBC count in torsion Test usually obtained for pre-operative purposes
Urinalysis and Culture R/o UTI Pyuria may be seen in Epididymitis
Gram stain, culture, rapid molecular amplification testing of urethral discharge -or- Nucleic amplification test of urine R/o sexually transmitted diseases
Color Doppler Ultrasound of the Scrotum Check perfusion R/o torsion if cannot be excluded on clinical grounds
25
Differential Diagnosis

• Testicular Torsion
• Torsion of Appendix Testis
• Epididymitis/Orchitis

• Trauma
• Incarcerated Inguinal Hernia
• Henoch-Schoenlein Purpura
• Referred Pain
• Non-specific

26
Differential Diagnosis

• Hydrocoele
• Varicocoele
• Spermatocoele
• Testicular Cancer

27
Torsion of the Testicle

• Inadequate fixation of the testis to the tunica
  vaginalis through the gubernaculum
• Bell-clapper deformity
• Twisting of the spermatic cord
• Venous compression and edema
• Ischemia

28
Torsion of the Testicle

• Peak incidence in the neonatal period and the
  pubertal period
• 65 occur during the 12-18 year old range due to
  increasing weight of the testicles

29
Torsion of the Testicle

• Abrupt onset of severe testicular or scrotal pain
  lt12 hours of duration
• 90 have associated nausea and vomiting
• Pain can be constant unless the testicle is
  torsing and detorsing
• Most boys report a previous episode in the past

30
Torsion of the Testicle

• Diagnosis is made clinically. Impression is
  stronger if there are previous episodes
• Doppler ultrasound should be done if there are
  uncertainty in diagnosis
• False positive scans (diminished blood flow)
• Large hydrocoeles
• Abscess
• Hematoma
• Scrotal hernia
• False negative scans
• Spontaneous detorsion or Intermittent
  torsion-detorsion

31
Torsion of the Testicles

• Timing of operation
• 4-6 hours (100)
• gt12 hours (20)
• gt24 hours (0)
• The contralateral testis should also be explored
  bell-clapper deformity is usually bilateral
• Surgical Detorsion Orchiopexy
• Orchiectomy if non-viable

32
Torsion of the Appendix Testis/Epididymis

• Pedunculated shapes of these structures
  predispose them to torsion
• Occurs most commonly in 7-12 year old boys

33
Torsion of the Appendix Testis/Epididymis

• Pain is of sudden onset, similar to testicular
  torsion
• The testicle is non-tender, but there is a tender
  localized mass usually at the superior or
  inferior pole
• () Blue dot sign gangrenous appendix
• Doppler ultrasound may be necessary to rule out
  testicular torsion will show a lesion of low
  echogenicity. Blood flow to the affected area
  may be increased
• Radionuclide scan may show the hot dog sign of
  the torsed appendage.

34
Torsion of the Appendix Testis/Epididymis

• Management

Bed rest, Analgesia, Scrotal Support
5-10 days out patient
Resolution
Surgery
Removal of the appendage exploration of
contralateral testis not necessary
No follow-up necessary
35
Epididymitis

• Inflammation of the epididymis
• Occur more frequently in late adolescent boys and
  even in younger males who deny sexual activity.
• Risk factors
• Sexual activity
• Heavy physical exertion
• Direct trauma
• Bacterial epididymitis think of anatomical
  abnormalities

36
Epididymitis

• () Sexual activity

• (-) Sexual Activity

• Chlamydia
• N. gonorrhea
• E. coli
• Viruses
• Ureaplasma
• Mycobacterium
• CMV
• Cryptococcus (HIV)

• Mycoplasma
• Enteroviruses
• Adenovirus

37
Epididymitis

• Acute or subacute onset of testicular pain
• History of urinary frequency, dysuria, and fever
• Normal vertical lie on exam, scrotal erythema,
  () scrotal edema, inflammatory nodule
• Normal cremasteric reflex, with negative Prehns
  sign

38
Epididymitis

• Doppler ultrasound may be necessary to rule out
  testicular torsion
• All patients should get a urinalysis and urine
  culture
• CDC guidelines in sexually transmitted boys
• Gram-stained smear if urethral exudates or
  intrautheral swab specimen or Nucleic
  amplification test
• Urine culture of a first void urine
• RPR and HIV testing

39
Epididymitis
ADMSSION CRITERIA CHILDREN SEXUALLY ACTIVE
Doubt diagnosis (?Torsion) () Leukocytes in urine Empiric antibiotics Bactrim/Keflex Ceftriaxone x 1 Doxycycline x 10 days
Severe pain () Leukocytes in urine Empiric antibiotics Bactrim/Keflex Ofloxacin
Immunocompromised (-) Leukocytes in urine Supportive treatment NON-BACTERIAL Levofloxacin
Unreliable patient (-) Leukocytes in urine Supportive treatment NON-BACTERIAL Levofloxacin
Non-compliance (-) Leukocytes in urine Supportive treatment NON-BACTERIAL Levofloxacin

• It is equally important to treat sexual partners
  if an STD is the likely cause.
• Supportive therapy Scrotal support, bed rest and
  NSAIDS

Other Causes Clues
CAUSES CLUES MANAGEMENT
Trauma Rarely compression of the testis against the pubic bone from straddle injury ? Testicular rupture Hematocoele ? Intratesticular hematoma Color doppler may diagnose the abnormality
Incarcerated Inguinal Hernia Audible bowel sounds in the scrotum
Henoch-Schonlein Purpura Nonthrombocytopenic purpura, arthralgia, renal problems, abdominal pain, GI bleeding Treatment is supportive ? bleeding in the GIT is more priority in management
Orchitis Usually viral (Mumps, Rubella, Coxsackie, Echovirus) Brucellosis Pain and tenderness of the testis with peculiar shininess of the scrotal surface Symptomatic treatment ? rest and ice packs, NSAIDS
41
Other Causes Clues
CAUSES CLUES MANAGEMENT
Referred Pain Other signs and symptoms may be apparent Examples include Urolithiasis Nerve root impingement Retrocecal appendicitis Tumor
Nonspecific Scrotal Pain Mild scrotal pain in the light of a normal exam Imaging is not necessary Treatment is not necessary
