Q

Epididymitis vs torsion?

A

-Epididymitis gradual vs torsion acute
-Epididymitis gives you +ve signs vs torsion doesnt
(-ve crew because its tied down. -ve Phrens because its still twisted)
-Epididymitis gives you urinary symptoms vs torsion does not

Q

What is the investigation of choice for Epididymitis?

What others might you do?

A

Do an USS (this will rule out torsion!!!!)

Also:

  • Dipstick+MSU (↑Nitrates,↑Leucocyte -suggest UTI cause)
  • Urethral swab w/ NAATs -(Chlamydia or gonorrhoea)
  • Bloods – HIV/syphilis
  • IgM/IgG serology if mumps is suspected

Q

Who should you refer to if you suspect Epididymitis?

A

-Ideally refer to same day/next day sexual health appt.
(if this is not possible just treat depending on risk factors)
e.g young, sexual partners, treat for STI

-If they are very unwell consider admitting to hospital, (particularly diabetic or immunocompromised)

Q

Epididymitis: If sexual health referral within 1 day you would just treat the cause according to risk factors. What are the risk factors and how would you treat accordingly?

A

Treat before results (based on risk factors)

STI (sexual partners, young)

  • Ceftriaxone 1g IM as single dose (gonorrhoea cover)
  • Plus doxycycline for 10–14 days (chlamydia cover)

Enteric organism e.g. E coli (35yrs+/low risk sex history/anal intercourse/recent catheter/urological instrumentation

Q

Pathophysiology of paraphimosis?

A

PARAPHIMOSIS IS A MEDICAL EMERGENCY

Tight foreskin retracts and is irreplaceable → prevents venous return → oedema glans → ischaemia/necrosis of glans

25
Q

What is the management of paraphimosis?

A

PARAPHIMOSIS IS A MEDICAL EMERGENCY

-Pain control
-Manual reduction (gradually with a saline soaked swab)
± ice to reduce swelling
± squeeze glans (reduce pressure)
± 50% glucose swab (oedema may follow osmotic gradient)
-If failed URGENT referral to urologist
-Surgical intervention may be required (dorsal slit reduction surgery± circumsision)

26
Q

Define erectile dysfunction

A

Inability to achieve or sustain an erection sufficient in rigidity of duration for sexual intercourse which is present for a minimum of 6 MONTHS

27
Q

List some vascular causes of ED

A 
HTN
DM 
CVD 
Hyperlipidemia 
Smoking
28
Q

List some neurogenic causes of ED

A 
Stroke
Brain / spinal cord injury 
Dementia 
Parkinsons disease 
MS
29
Q

List some endocrine causes of ED

A

Hypogonadism
Hyperprolactinemia
Thyroid disorders

30
Q

List some medications than can cause ED

A

Anti HTN - beta blockers, thiazide diruetics

Antidepressants - SSRIs

Dopamine antagonists

31
Q

How do dopamine antagonists cause ED?

A

Dopamine receptors blocked in tuberoinfundibulnar pathway, leading to an increase in prolactin secretion from the anterior pituitary

This leads to a decrease in GnRH secretion from the hypothalamus (negative feedback)

This leads to decreased LH secretion from the anterior pituitary which leads to decreased testosterone production from the Leydig cells

This leads to hypogonadotropic hypogonadism

32
Q

List some iatrogenic causes of ED

A

Radical prostatectomy

Pelvic radiation

33
Q

List some other causes of ED

A
  • Trauma
  • Alcohol abuse
  • Peyronie disease - scar tissue develops on the penis and causes curved, painful erections
  • Psychological - depression, anxiety, stress
34
Q

What bloods are done for ED?

A

Causes

  • Testosterone levels
  • SHBG (sex hormone binding globulin)
  • Prolactin
  • LH
  • FSH
  • TSH

Risk factors

  • Fasting glucose / HbA1c
  • Lipid profile
35
Q

Other than bloods, what investigations can be done for ED?

A

Nocturnal penile tumescene measurement

  • Doppler US or arteriography to identify suspected arterial inflow or venous leaks after injection of a vasodilatory agent
  • Organic causes=reduced
  • Psychological causes=erections happen throughout night
36
Q

What is the management of ED? (conservative and medical)

A 
Management of erectile dysfunction
Conservative 
-Treat any comorbidities that may be causing 
-Review drug chart for causes 
-Counsiling if psych cause

Medical

  • Phosphodiesterase 5 inhibitors 1st line
  • Testosterone replacement if needed
  • If pituitary/hypothalamic cause>excise pituitary adenoma causing ↑Prolactin
37
Q

How do phosphodiesterase 5 inhibitors work? Examples?

A

Slidenafil (viagra), tadalafil, vardenafil

Inhibit PDE 5 enzyme that normally breaks down cyclic GMP→ ↑cyclic GMP levels ↑ intracavernosal NO →vasodilation

38
Q

What are some considerations for prescribing phosphodiesterase 5 inhibitors?

A
  • Contraindicated in patients taking NITRATES due to profound HYPOTENSION
  • May cause orthostatic hypotension in those taking alpha-adrenergic antagonist eg for BPH, take 4 hrs apart
39
Q

How do nitrites work? Examples

A

Increase the release of nitric oxide (NO) in vascular smooth muscle cells, which leads to smooth muscle relaxation and subsequent vasodilation

Eg nitroglycerin, sodium nitroprusside, isosorbide mononitrate

40
Q

What is the mechanical management of ED?

A

Vacuum pump

  • hollow cylinder that is placed onto the penis with a penis ring
  • blood sucked into the penis
  • tube taken off but the ring stays there>maintains erection
41
Q

What is the surgical management of ED?

A

Implantation of penile prosthesis

Last resort

42
Q

What is hypospadias?

Common places for it to happen?

A

Common congenital malformation
-Incorrect positioning of the urethral meatus due to failure of urethral folds and foreskin to fuse on ventral penis

-The meatus may be located centrally (penile shaft), anteriorly/distally (glans/corona), or posteriorly/proximally (scrotum or perineum)

43
Q

How may hypospadias present?

A
  • Abnormal foreskin - DORSAL HOOD
  • Ventral penile curvature
  • May have two meatal openings
  • Proximal hypospadias are associated with BIFID scrotum
  • Associated with inguinal hernias and cryptorchidism
44
Q

What is the management of hypospadias?

A

Significant displacement or symptomatic micturition may need surgery:
- Reconstruction of urethra, penis and scrotum (between 6months-2 years) (urethroplasty / orthoplasty)

(if they have curvature problems correct these first then do urethroplasty at least 6 months later)

45
Q

What is contraindicated in hypospadias?

A

Circumcision (they need the foreskin in the operation)

46
Q

What is cryptorchidism?

A

Failure of one or both testicles to descend to their natural position in the scrotum

47
Q

What are possible variations of cryptorchidism?

A

Inguinal
Intra-abdo
Ascending

48
Q

What is the management of cryptorchidism?

A

Surgery between 6-18 months

Orchidopexy - exposure and fastening of the testicle to the scrotum (open or laparoscopic)

49
Q

When would you re examine if they had unilateral cryptorchidism?

A

At birth: re-examine the infant at 6–8 weeks of age.

At 6–8 weeks of age: re-examine the infant at 4–5 months of age

At 4–5 months: (corrected for gestational age), if still undescended, arrange to paediatric surgery/urology to be seen by 6 months

50
Q

If they are bilateral undescended testes at birth what should you do?

A

If bilateral at birth: urgent pads referral (24 hours) to look for endocrine/sexual disorders

-If still bilateral at 6-8 weeks: urgent 2 week referral to pads

51
Q

What is the management of cryptorchidism?

A

Surgery between 6-18 months

Orchidopexy - exposure and fastening of the testicle to the scrotum

If non-palpable, potentially therapeutic open or laparoscopic orchidopexy

52
Q

What tumour markers are associated with germ cell/testicular cancers?

A 
Alpha fetoprotein (aFP) 
hCG

*do a LDH blood test as well (high cell turnover)

53
Q

How may testicular cancer present?

A
  • Slow progression (weeks to months)
  • Usually painless testicular mass
  • May feel dull ache / heavy sensation
54
Q

What may an examination show in testicular cancer?

A
  • Palpation of solid mass
  • Possible manifestations of metastatic disease eg LN/cannon ball mets)
  • Possible ipsilateral lower limb swelling = venous engorgement due to obstruction
55
Q

What are the most common forms of testicular cancer?

A

Germ cell tumours are the most common (95%)

  • These can be broken down further:
    a) Seminoma (most COMMON type of germ cell)
    b) Embronal/Teratoma/Teratocarcinoma

Non germ cell (from leydic or sertoli cells)

56
Q

Diagnostic imaging for testicular cancer?

A

USS is diagnostic!!

NEVER DO BIOPSYS IN TESTICULAR CANCER

57
Q

Whats the treatment for testicular cancer?

A

Surgery
-inguinal orchidectomy (reduce the risk of seeding)

Medical
-if METASTATIC (present with cannon ball mets)
DO CHEMO 1ST LINE (responds well) before surgery
-chemotherapy after surgery if needed

58
Q

Hydrocele vs epidydmal cyst?

A
  • both painless swellings the DO transilluminate
  • epidydimal cysts can be separated from testes
  • hydrocele CANNOT be separated (surround testes)
