23
Q

Which conditions in a patient’s history would cause one to consider the possibility of a squamous cell carcinoma of the bladder?

A

Schistosomiasis – parasitic infection of the urinary tract/intestines by shistosomes (parasitic flatworms)

24
Q

What is a Renal Transitional Cell Carcinoma?

A

Renal TCC is a malignant tumour arising from the transitional epithelial cells lining the urinary tract from the renal calyces to the ureteral orifice

presents with haematuria, obstruction occurs earlier

25
Q

What are the risk factors for renal TCC?

A
  • Smoking
  • Phenacetin abuse
  • Balkan’s nephropathy
26
Q

What is the standard treatment of renal TCC?

A

Nephro-ureterectomy – kidney, fat, ureter, cuff of bladder as patients have a 40% chance of developing bladder cancer

  • scan regularly to check for bladder cancer
    *
27
Q

What is the treatment for metastatic TCC (renal/bladder)?

A
  • Systemic chemotherapy
  • Biological therapies – immunotherapy
28
Q

What is prostate cancer?

A
  • Prostate cancer is the slow-growing development of cancer in the prostate gland of the male reproductive system
  • It commonly forms in the peripheral zone of the prostate but benign tumours also form in the transitional zone

BPH → hypertrophy of prostate more central

29
Q

What are the risk factors for prostate cancer?

A
  • Age (increases)
  • Family history e.g. BRCA2 gene mutation
  • Ethnicity (Black > White > Asian)
30
Q

What does screening for prostate cancer involve?

A

PSA testing – prostate specific antigen blood test

31
Q

When should a doctor refer a patient for PSA screening?

A
  • When they present with associated symptoms
  • When they come to discuss a family member who has prostate cancer / because they have read about PSA
32
Q

What are the issues with PSA testing results?

A
  • You can’t rely on a PSA within 6 weeks of a urinary infection
  • Having a normal PSA does not mean you do not have prostate cancer
  • You can have a normal PSA but an abnormal feeling prostate on DRE
33
Q

State four other causes of raised PSA

A
  • Infection
  • Inflammation
  • Large prostate
  • Urinary retention

(prostate cancer)

34
Q

How do patients with prostate cancer present?

A
  • Urinary symptoms
  • Bone pain
  • Abnormal DRE (digital rectal exam)
  • Incidental finding (at transurethral resection of prostate)
35
Q

Outline the diagnostic pathway for prostate cancer

A
  • DRE + Serum PSA → transrectal ultrasound-guided biopsy of prostate
  • Lower urinary tract symptoms → transurethral resection of prostate (TURP)
36
Q

What are the 5 factors influencing treatment decisions for prostate cancer?

A
  • Age
  • DRE (localised, locally advanced, advanced)
  • PSA level
  • Biopsies (Gleason grade, extent)
  • MRI / bone scan (metastases)
37
Q

How is localised prostate cancer treated?

A
  • Surveillance
  • Robotic radical prostatectomy
  • Radiotherapy
38
Q

How is locally advanced prostate cancer treated?

A
  • Surveillance
  • Hormones
  • Hormones & radiotherapy
39
Q

Describe the treatement of metastatic prostate cancer

A
  • Hormones(± chemotherapy):

I. Surgical castration

II. Medical castration: LHRH and GnRH antagonist (androgen blocker to stop testosterone)

  • Palliative care:

I. Single-dose radiotherapy

II. Chemotherapy

40
Q

Why is it possible to feel changes in the prostate during a digital rectal examination?

A
  • Tumour normally occurs in peripheral zone of prostate gland
  • Posterior side of the prostate is right next to the anterior wall of the rectum
41
Q

Why do patients with prostate cancer present with urinary symptoms?

What are these symptoms?

A

Tumour compresses the prostatic urethra, hence producing LUT symptoms:

  • Urinary retention
  • Urinary frequency
  • Dysuria
  • Nocturia
42
Q

Why do patients with prostate cancer present with lower back pain?

A
  • Bone metastases (main)
  • Lymphatic metastases to seminal vesicles (nerve compression)
43
Q

staging of bladder TCC

A

75% are superficial so only within the inside of the bladder

T3 and T4 are all tumours that spread from inside to outside => more invasive

44
Q

how do you diagnose and treat TCC

A
  • Investigate with cystoscopy and biopsy
    *
intravesical BCG stimulates the bodies immune response
45
Q

what are some investigations you could request and what to they suggest

A
46
Q

how should the prostate feel normally and how does it feel during BPH and prostate cancer

A

normal: soft and spongy and should feel two lobes

BPH: larger and a little but firmer but still feel two different lobes

cancer: irregular, bumpy and hard and can’t feel the two lobes separately

47
Q

pathology of prostate cancer

A

T1: unsuspected and can’t palpate

T2: tumour confined to prostate

T3: local extension of tumour beyond prostatic capsule

T4: tumour fixed onto other structures

48
Q

describe this bone scan and how it has come about

A
  • this occurs in advanced prostatic cancer
  • patients can develop sclerotic bone lesions
  • these are hot spot on bone scan
49
Q

what is a possible mistake that can happen during surgery of the prostate

A

you can hit the pudendal nerve and it can effect the bladder and continence

50
Q

what hormone causes prostatic cancer

A

testosterone

as you age it gets converted into dihydrotestosterone which is more potent and can promote tumour growth

51
Q

side effects of castration

A

hot flashes

impotence

thinning of bones

diminished muscle mass

increase in breasts

weight gain

mood changes ;

52
Q

what is polycystic kidney disease

A
  • accounts for 8-10% of CKD
  • most common inherited nephropathy
  • cysts can develop anywhere and compress surrounding parenchyma and impair renal function
  • cysts can develop in childhood but not cause problems till adulthood
53
Q

what fills the cysts in Polycystic kidney disease

A

kidneys are large and filled with yellow fluid like cysts replacing parenchyma

haemorrhage in the cysts can occur

cysts are lined with cuboidal epithelium

54
Q

what conditions can polycystic kidney disease cause

A

hyeprtension and a CKD

it is autosomal dominant condition

an be associated with valvular heart disease, diverticular disease and berry aneurysm

must avoid contact sports and it can cause the cysts to burst and cause lots of bleeding

55
Q

when should family members of people with polycystic kidney disease be screened

A
  • when there is a large number of family members with the disease available for linkage
  • family members should screen on an annual basis for high BP to urine dipstick abnormalities
  • late teens get US, if there are no cysts then its likely she does not have the disease
