definition

Epidemiology

Examination

Symptoms:

Investigation

What is the treatment for BPH(conservative, medical and Surgical)?

A

definition: slowly progressive hyperplasia of the periurethral (transitional) zone of the prostate gland

Epidemiology: •VERY COMMON – most common cause of LUTS in men

Q

What are the different types of urinary incontinence and what are their symptoms?

A
  1. stress incontinence: poor bladder closure - stress on bladder through increased abdominal pressure through movement -RF: childbrith
  2. urge incontinence: overactive detrussor muscle, symptoms include sudden urge to pee
  3. Functional: due to stroke or dissabilty can’t get to the toilet in time
  4. Overflow: involuntary release of urine from an overfull bladder, in the absence of any need to urinate (ussualy not aware)

He has also noticed that he feels much weaker than usual, and is struggling to complete his usual gym routine. He has been to see his GP once before because his blood pressure was high on multiple occasions, however, he did not return to receive treatment. His blood pressure is measured again and it is 184/94 mm Hg. What would you expect to see on the ECG of this patient?

A

E U waves

23
Q

Why are varicoecele more common on the left?

A

Reasons for being more common on the left:

  • Angle at which the left testicular vein meets the left renal vein
  • Lack of effective valves between the left testicular vein and the left renal vein
  • Increased reflux from compression of the left renal vein
24
Q

Epididymitis and Orchitis

  • Definition
  • Epidemiology
  • Causes
  • Symptoms and signs
  • Investigations
A

Definition: inflammation of the epididymis or testes

Epidemiology: •Most common in 20-30 yr olds

Causes:

  • > 35 yrs: Coliforms (e.g. Enterobacter, Klebsiella)
  • Others: mumps, Candida

Symptoms and signs:

  • Painful, swollen and tender testis/epididymis
  • NOTE: less acute onset than torsion
  • Penile discharge (if STI)
  • Fever
  • Enquire about sexual history

Investigations:

  • Urine dipstick
  • Urine MC&S
  • Bloods (FBC, CRP)
25
Q

What are possible differential of scrotal pain?

A

Epididymo-orchitis

Strangulated inguinal hernia

Testicular torsion

26
Q

Testicular Cancer

Background

Types

Symptoms

investigaitons

A

Background:

  • Commonest malignancy in males between 20-40 yrs
  • Risk Factors: maldescended testes

Types:

  • Seminoma - 50%
  • Non-Seminoma (e.g. teratoma) – 30%
  • Others: Sertoli and Leydig cell tumours

Symptoms:

  • Painless, hard testicular mass
  • Testicular swelling/discomfort
  • Backache (metastasis to para-aortic nodes)

Investigaitons:

  • Tumour Markers
    • a-fetoprotein
    • b-hCG
    • Lactate Dehydrogenase
  • Testicular Ultrasound
  • CT – allows staging
27
Q

Are testicular cancers biopsied?

WHy?

A

Testicular cancers are NOT usually biopsied because it may risk spreading the cancer.

28
Q

From what tissue do seminomas and non- Seminomas arise from?

A

Seminomas and Non-Seminomas both arise from germ cells (cells that give rise to gametes).

They are categorised based on the histological appearance of the tumour.

Seminomas will look a lot like the tissues of the seminiferous tubules.

Non-seminomas (e.g. teratoma) will appear very different from the testicular tissue.
