Q

What are some of the consequences of phimosis?

A
  • Poor hygeine - increased STDs
  • Pain on intercourse - splitting/ bleeding of foreskin
  • Balanitis (inflamed glans)
  • Posthisis (inflamed foreskin/ prepuce)
  • Balanitis Xerotica Obliterans (BXO)
  • Parphimosis - when trying to retract forekin and it gets stuck
  • Urinary retention
  • Penile cancer

What should establish on examination of a patient who presents with a scrotal lump?

A

Varicocele (bag of worms)

25
Q

A

An imbalance of fluid production and resorption between the tunica albuginea and tunica vaginalis

Presents as slow/sudden onset uni/bilateral scrotal swelling

29
Q

What do you find on examination of a man with hydrocele?

A
  • Testis is not separately palpable
  • Can usually get above it
  • Transilluminates
30
Q

What do you find on examination of an epididymal cyst?

A
  • Usually painless
  • Separate from testis
  • Can get above it
  • Transilluminates
31
Q

How does varicocele present?

A
  • Dull ache at end of the day
  • May be associated with reduced fertility (if bilateral)
  • Bag of worms
  • non-tender
  • May have palpable abdominal/ renal mass
  • Will leave alone in most adults- can treat in young men
32
Q

What is the treatment for testicular tumours?

A
  • Inguinal orchidectomy

33
Q

How do you treat an epididymal cyst?

A
  • Reassure
  • Excise if large
34

How do you treat an adult hydrocele?

A
  • If testis are normal on ultrasound:
  • reassure
  • Surgical removal if large/ symptomatic
35
Q

How do you treat a varicocele?

A
  • Reassure
  • Radiological embolisation if symptomatic, infertile, affecting growth of testis in adolescent

A
  • Prostatic enlargement
    • BPH
    • Cancer
  • Phimosis/ urethral stricture/ meatal stenosis

  • Over-distension (too much fluid and not urinating stretches bladder)
  • Post surgical
  • Neurological e.g. cauda equina
38
Q

How do you treat acute, painful urinary retention?

52
Q

What drugs can you give to treat BPH?

A

1. TAMSULOSIN

An alpha blocker

Works by relaxing smooth muscle within the prostate and the bladder for rapid symptom relief

2. 5a- REDUCTASE INHIBITORS

FINASTERIDE or DUTASTERIDE

Act by shrinking the prostate by androgen deprivation. Slower symptoms relief than alpha blocker, slows progression and reduces risk of retention

53
Q

A

Green: normal

Yellow: suggestive of urethral stricture

Red: Suggestive of prostatic obstruction
