8. Why EMERGENCY?
• Potential for testicular loss and infertility
• Legal action can be taken
• Accurate diagnosis limited by similarity of
presentation and physical findings of different
causes
• Radiological techniques is helpful, but may
delay treatment
• Operation may be needed for Dx and Tx
purposes
10. Testicular torsion
• Torsion of the testis (spermatic cord) → strangulation of gonadal blood
supply → testicular necrosis and atrophy.
• Window of opportunity to salvage - within 6 hours!
• Acute scrotal swelling in children indicates torsion of the testis until
proven otherwise
_________________________________________________________
• Acute-onset agonising pain over hemiscrotum, groin, lower abdomen
• Nausea and vomiting
• Scrotal swelling with erythema
• High lie of testis, palpable thickening tender cord
• May occur at rest or may relate to sports or physical activities (sometimes
upon straining at stool, coitus, during sleep)
• May describe similar previous episodes, which may suggest intermittent
testicular torsion (spontaneous detorsion)
• No voiding problems or painful urination
• Difficulty in ambulation
11. • Predisposing causes
1. Inversion of testis
– transverse lie/upside down
2. High investment of tunica vaginalis
3. Separation of epididymis from body (long mesorchium)
– torsion without involving cord, confined to pedicle that connect testis
with epididymis
• 2 types of torsion:
• Extravaginal (5%)
- testis rotates freely prior to fixation of testis
- more common in neonates
• Intravaginal (16%) : Bell Clapper deformity
- lack of fixation (testis freely suspended within tunica vaginalis)
- peak incidence at adolescence age 13
12. • Incidence
– Most common between 10-25yo (1:4000)
• Pathophysiology :
Violent contraction of abdominal muscles → contraction of cremaster
→ favors rotation around vertical axis
• Torsion of 3-4 turns : irreversible changes (necrosis)
within 2 hours
• Torsion of 1 turn (360:) : well tolerated for 12 hours (20% viability)
necrosis after 24 hours
• Torsion of 90: : well tolerated for 7 days

13.
14. • O/E
– Extremely tender, enlarged
– High riding testis
– Reactive hydrocele
– Scrotal wall erythema
– Ecchymosis
– Cremasteric reflex
• if present, no torsion
• if absent 66% rule in torsion
• Ix
– UFEME : TRO UTI/epididymorchitis, ↑leucocytes in 30% patients
– FBC : ↑TWC in 60% patients
– US Doppler scrotum/testis
– Contrast MRI : evidence of torsion knot or whirlpool patterns
– Nuclear testicular scan/scintigraphy
• to ddx torsion from acute epididymitis by demonstrating cold spot and ring
signs.
* Radiologic techniques are helpful but may delay treatment*
15. US Doppler scrotum/testis
• Sensitivity 80 - 90%
Specificity 100%
• The case on the left shows a testicular torsion of the left testis.
• Complete absence of intratesticular blood flow and normal
extratesticular blood flow on color Doppler images is diagnostic, if
the flow is normal in the contralateral testis.
18. • Management
1. Alleviation of symptoms
– Analgesic : IV/IM pethidine
– Antiemetic : IV stemetil 10mg, IV maxolon
– Anxiolytic : IV valium
2. Manual Detorsion
• Rotate testicle in medial to lateral direction “open the book”
• usually 1-2 complete turns
• relief of pain
• return of blood supply to testicle (confirmed with US)
• additional time before OR
• patient may not tolerate.
3. Surgical exploration
• Bilateral orchidopexy – to prevent future torsion
• Orchidectomy + contralateral orchidopexy
4. Placement of testicular prosthesis – after 6 months of orchidectomy via
inguinal incision
19.
20. • Prognosis
– < 6 hours, 90% salvage
– > 6 hours, 20% viability likelihood for orchidectomy
– > 24 hours, 100% loss and atrophy
• Complications
– Testicular atrophy : may occur days-to-months after
the torsion has been corrected.
– Severe infection of the testicle and scrotum is also
possible if the blood flow is restricted for a prolonged
period.
21. Epididym-/orchitis
• Most common cause of acute
scrotum(75-80%)
• Acute : < 6 weeks (CDC, STD treatment guidelines)
• Young men – hx of STD exposure
(Chlamydia trachomatis, Ureoplasma urealyticum,
Neisseria gonorrhea)
• Children : UTI, urinary tract structural
anomalies (E. coli, Streptococci, Staphylococci, Proteus)
• Older men : BPH, post vasectomy, post urological operative
procedure/instrumentation, indwelling catheter, infectious
prostatitis, TB
• Orchitis : Syphillis, leprosy
• Viral cause : Mumps (18% males), usually a/w parotid swelling
22. • Chronic tuberculous epididymo-orchitis usually
insidious onset a/w “cold” abscess discharge
• Syphillis
– usually affects body of testis
1. Bilateral orchitis : congenital syphillis
2. Interstitial fibrosis → painless destruction of testis
3. Gumma : unilat. painless slow growing swelling
• Leprous orchitis : testicular strophy in 25%
male lepers.
24. • O/E
– Scrotal swelling (secondary hydrocele), enlarged,
erythematous and indurated
– Indistinguishable testis (in later stage)
– Cremasteric reflex is usually present
– Prehn sign positive : elevation of the scrotum may
provide relief of pain.
– Pyuria
25. • Ix :
– UFEME : ↑leucocytes > 10 visual field
– MSU C&S/pus C&S : bacterial growth
– Venereal disease screening : for sexually active men
– Immunofluorescent antibody test, if suspected mumps
– US scrotum/testis
– Flex CU : to detect structural anomalies
– Scrotal exploration or aspiration (rare)
• If torsion cannot be ruled out
• Complications eg. abscess, pyocele, testicular infarction
• Failed conservative treatment in 48-72 hours
26. US scrotum/testis (sensitivity 82-100%, specificity 100%)
• The case on the left shows the typical features of
epididymitis.
• Swollen, heterogeneous, hyperemic
• Hydrocele
• Scrotal wall thickening.
• With color doppler there is increased flow.
A normal epididymis has only limited colorflow.
27. • Diagnostic Criteria for Epididymitis
– Gradual onset of pain
– Dysuria, discharge, or recent instrumentation/CBD
– History of genitourinary abnormality
(UTI, neurogenic bladder, hypospadias, etc.)
– Fever > 38:C
– Tenderness and induration at epididymis
– Abnormal UFEME (>10 leucocytes visual fields/RBC)
• 3 or more findings present - definite Epididymitis
• 2 findings present - probable Epididymitis
• 1 finding present - possible Epididymitis
28. • Management
1. Antibiotic therapy : if UFEME/MSU C&S positive
for infection
– Suspect STD : IV rocephine + T. doxycycline x 10/7
– Suspect UTI : IV/T. ciprobay x 10/7
– Others : Azithromycin, Bactrim, Gentamicin,
2. Bed rest/scrotal elevation : if UFEME/MSU C&S
negative → sterile chemical epididymo-orchitis
(structural anomalies)
3. Supportive therapy : ice packs, cool Sitz bath
4. Analgesia : opioids, NSAIDs
5. Orchidectomy : if complications developed
30. • Prognosis
– Resolution of sx in 2-4 weeks if properly treated
– Chronic epididymoorchitis may have frequent mild
attacks, may have lumps in scrotum due to
fibroplasia
– May have threat of infertility
31. Torsion of testicular/epididymal appendage
• Remnant of Wolffian(epididymis)/Mullerian(testis) duct
• Can be twisted → torsion
• o/e : testis palpable with normal lie, edematous, torsed
appendage palpable over upper pole of testis, “blue-dot sign”
if ecchymotic
• US Doppler : normal testicular perfusion with hyperemia over
appendage
• Self limiting (infarct → atrophy)
32.
33. Testicular trauma
• Damage occurs when the testis is forcefully
compressed against the pubic bones
• Traumatic epididymitis : noninfectious
inflammatory condition occurs within a few days
after a blow to the testis. Treatment is same like
nontraumatic epididymitis.
• Scrotal trauma can also result in intratesticular
hematoma, hematocele or laceration of the
tunica albuginea (testicular rupture).
• US Doppler : imaging technique of choice.
34. Degree of testicular trauma
1. Blunt (85%) : direct external force to testicle
2. Penetrating (15%) : sharp objects, high velocity missiles
3. Degloving : Scrotal skin sheared off
• Genital self-mutilation : if testis vital, reimplantation is
possible
• Pathophysiology : rupture → intratesticular hemorrhage
in tunica vaginalis → HEMATOCELE! → extends up to
epididymis → bleeding → SCROTAL HEMATOMA!
35. • O/E
– Swelling
– Tenderness
– Ecchymosis
– Scrotal wall thickening
• Palpable testis : unlikely rupture
• Difficulty in palpation : US urgent to determine
degree of testis injury
36. • Management
1. Bed rest
2. Scrotal support
3. Pain relief
4. Testicular debridement
5. Closure of tunica albuginea
• Penetrating trauma : urgent exploration to assess
degree of injury and control intratesticular hemorrhage
• Degloving injury : often need debridement, skin closure
may not be possible
37. • Indications for scrotal exploration include the
following:
– Uncertainty in diagnosis after appropriate clinical and
radiographic evaluations
– Clinical findings consistent with testicular injury
– Disruption of the tunica albuginea
– Absence of blood flow on US Doppler studies
• Complications
– Testicular infection
– Testicular atrophy
– Testicular necrosis
– Infertility
– Disruption of male hormonal functions
39. Hydrocele
• A collection of serous fluid in the tunica vaginalis
• Congenital : occurs in infants due to patent processus
vaginalis peritoneal fluid can enter the scrotum
Primary. (idiopathic)
• Develop slowly
• Large
• Hard & tense
• No defined cause
• Over 40s
Secondary
• Develop rapidly
• Small
• Lax
• Underlying cause
• younger age group(20-40)
40. • Congenital hydrocele: processus vaginalis is patent &
connects to the peritoneal cavity. In children <3yrs
• Infantile hydrocele: the tunica and processus
vaginalis are distended to the superficial inguinal
ring. There is no connection. Occurs in all ages
• Hydrocele of the cord: swelling near the spermatic
cord. Ddx hernia, lipoma of the cord
41. • O/E
often bilateral
• Can “get above it”
• Testes cannot be felt separately
• Transluminates
• Fluctuant
• Fluid thrill
• Not compressible or pulsatile
• Can’t be reduced
• Normal skin color & temp
• Not tender if primary (may be tender if secondary)
• Size can be reach up to 10-20cm in diameter
• Surface smooth
42. • Ix : US scrotum to ddx from other causes
• Management :
• If congenital hydrocele persists beyond the age of 1year, surgical treatment
is indicated. This involves the division and ligation of the processus.
• In an adult with primary hydrocele
Surgery
Opening the tunica vaginalis longitudinally
Emptying hydrocele
Everting the sac
Suturing it behind the cord thus obliterating the potential space
Aspiration recurance
In elderly patient who are not fit for surgery
• Secondary hydrocele treat the underlying cause
43. Testicular tumor
• Rare 1–1.5% of male cancers.
• mainly affects younger men of 30 – 40yo
• 90 - 95% arise from germ cells and are either
seminomas (45%) or nonseminomas(50%).
(Nonseminoma : choriocarcinoma, embryonal carcinoma, teratoma,
and yolk sac tumors)
• 5% are lymphomas, sertoli cell tumours or
leyding cell tumours.
• Prognosis is good particularly if there was no
lymph node involvement
44. • Incidence and frequency
– Seminomas in 30-40y.
– Teratomas in 20-30y.
– Imperfectly descended testes have a 20-30 times
increased incidence of malignancy.
45. Recommended pathologic classification (EUA, 2011)
Germ cell tumours
• Intratubular germ cell neoplasia, unclassified type
• Seminoma (including cases with syncytiotrophoblastic cells)
• Spermatocytic seminoma (mention if there is a sarcomatous component)
• Embryonal carcinoma
• Yolk sac tumour
• Choriocarcinoma
• Teratoma (mature, immature, with malignant component)
• Tumours with more than one histologic type (specify percentage of individual components)
Sex cord/gonadal stromal tumours
• Leydig cell tumour
• Malignant Leydig cell tumour
• Sertoli cell tumour (lipid-rich variant, sclerosing, large cell calcifying)
• Malignant Sertoli cell tumour
• Granulosa (adult and juvenile)
• Thecoma/fibroma group of tumours
• Other sex cord/gonadal stromal tumours (incompletely differentiated, mixed)
• Tumours containing germ cell and sex cord/gonadal stromal (gonadoblastoma)
Miscellaneous nonspecific stromal tumours
• Ovarian epithelial tumours
• Tumours of the collecting ducts and rete testis
• Tumours (benign and malignant) of nonspecific stroma
47. Risk factors for testicular cancer
Epidemiologic risk factors
• History of cryptorchidism
• Klinefelter syndrome
• Testicular cancer in first-grade relatives
• Contralateral tumour
• Testicular intraepithelial neoplasia or infertility
Pathologic prognostic risk factors for occult metastatic disease (stage I)
1. Seminoma
• Tumour size (4 cm)
• Invasion of the rete testis
2. Nonseminoma
• Vascular/lymphatic invasion or peritumoural invasion
• Proliferation rate (MIB-1) >70%
• Percentage embryonal carcinoma >50%
Clinical risk factors (metastatic disease)
• Primary location
• Elevation of tumour marker levels (AFP, B-HCG)
• Nonpulmonary visceral metastasis*
48. • Dx is made based on
1. Clinical examination of the testis
2. General examination to exclude enlarged
nodes or abdominal masses
3. US to confirm testicular mass.
49. Signs
• can “get above it”
• Testes cannot be felt separately
• Harder than normal testis
• Dull to percussion hydrocele
• No pain
• Irregular, different sizes
• Surface usually smooth (sometime irregular or
nodular)
50. Symptoms
• Painless swelling of the testis
• Heaviness in the scrotum
• Maybe history of trauma delays diagnosis
• Tiredness, LOW ,LOA
• Abdominal pain if lymph nodes are enlarged
• Swelling of legs caused by lymphatic or
venous obstruction
• Infertility
• Secondary hydrocele
51. • O/E
– Painless unilateral mass in the scrotum or the
casual finding of an intrascrotal mass.
– Gynaecomastia (common in nonseminomatous
tumor)
– Back and flank pain (rarely)
52. Ix :
US testis
CXR – to see cannon ball lesion if metastasized
Tumour markers: AFP, βHCG, LDH
CT TAP
CT brain
CT spine
Bone scan
US liver
53. • Serum tumour markers : prognostic factors used in diagnosis
and staging (LDH).
• The lack of an increase does not exclude
• testicular cancer
• LDH levels are elevated in 80% of patients with advanced
testicular cancer, therefore should always be measured in
advanced cancer
• Tumour markers must be reevaluated after orchidectomyto
determine half-life kinetics.
• The persistence of elevated serum tumour markers 3 wk after
orchidectomy may indicate the presence of disease, whereas
its normalisation does not indicate absence of tumour.
• Tumourmarkers should be assessed until they are normal, as
long as they follow their half-life kinetics and no metastases
• During chemotherapy, the markers should decline;
persistence has an adverse prognostic value.
54.
55. Management
• Inguinal exploration and orchidectomy
• If the diagnosis is unclear, a testicular biopsy
(enucleation of the intraparenchymal tumour) should
be taken for HPE
• If metastasized : delay orchidectomy
1. If seminoma: Start radiotherapy plus
chemotherapy.
2. If teratoma: combination chemotherpay 3
drugs(etoposide, vinblastine, methotrexate,
bleomycin, cisplastin)
56. Organ-preserving surgery
• Synchronous bilateral testicular tumours,
metachronous contralateral tumours, or in a
tumour in a solitary testis with normal
preoperative testosterone levels, provided
tumour volume is <30% of testicular volume
• Radiotherapy may be delayed in fertile
patients who wish to father children
• must be carefully discussed with the patient
