Q

What cell type lines the inside of the bladder?

1 - transitional epithelium
2 - stratified columnar
3 - stratified cuboidal
4 - pseudocolumnar

A

1 - transitional epithelium
Called transitional as they change their shape and structure as the bladder stretches

There are 3 types of cell layers:

  • basal, intermediate, superficial
  • basal layer fosters the epithelial stem cells in order to provide constant renewal of the epithelium
  • most impermeable membrane in the body due to highly keratinized cellular membrane

CT-PET is used to stage Transitional Cell Carcinoma of the bladder and ureter. Which of the following stages does NOT come under the heading of non-invasive bladder cancer?

1 - T3 tumour invades perivescular tissue

3 - Ta: cancer only affecting the urothelium and projecting into the bladder
3 - T1: cancer invading the connective tissue layer beyond the urothelium, but not the muscle layer

1 - T3 tumour invades perivescular tissue

  • > T2 is muscle invasive bladder cancer and any lymph node and metastatic cancer
22
Q

Which of the following definitions is stage T1?

2 - tumour invades surrounding tissue
3 - tumour is confined to the inner bladder (carcinoma in situ)
4 - tumour invades the muscle

A

3 - tumour is confined to the inner bladder (carcinoma in situ)

23
Q

4 - tumour invades the muscle

A

4 - tumour invades the muscle

24
Q

2 - tumour invades surrounding tissue
3 - tumour is confined to the inner bladder (carcinoma in situ)
4 - tumour invades the muscle

A

2 - CT-CAP
- CAP = chest, abdo and pelvis

Q

In a patient with muscle invasive bladder carcinoma, there are a myriad of treatments available:

  • Neoadjuvant chemotherapy such as Gemcitabine and Cisplatin
  • Cystectomy (bladder removal) with an Ileal conduit or Neobladder
  • Radiotherapy

Metastatic Disease includes:
- Supportive care
- Chemotherapy
- Palliative (haemostatic) - radiotherapy

A

Neoadjuvant chemotherapy: Cisplatin-based combination chemotherapy is recommended before radical cystectomy for eligible patients.
Radical cystectomy: Complete surgical removal of the bladder, prostate or uterus, and regional lymph nodes. Urinary diversion options include ileal conduit, continent cutaneous reservoir, or orthotopic neobladder.
Bladder-sparing approaches: For select patients, a multimodal approach combining maximal TURBT, radiotherapy, and chemotherapy may be considered.
Adjuvant chemotherapy: May be considered for patients with high-risk features following cystectomy or bladder-sparing treatment.

33
Q

62 year old male who works as a mechanic presents to practice nurse with a potential UTI and painless haematuria for 2 weeks. He smokes and is urinating more often. Which of the following would be the best method to confirm a diagnosis?

1 - ultrasound
2 - MRI
3 - cystoscopy
4 - CT scan

A

3 - cystoscopy

Allows imaging and biopsy

34
