Q

What to do if you find a tumour on Flexi?

A

Stay Calm

Wait to finish cystoscopic examination
Ask them to empty bladder get comfortable and come back in with relative
Bring CNS into the room
Gently explain likely diagnosis and following steps
Explain will need histological confirmation before being sure
Provide Contact details for CNS and the Urology POD
Provide leaflets regarding procedure and bladder cancer
Explain results will be discussed in MDT a week after operation at which point we can discuss treatment going forwards

Ix:
CT Urogram
Book for TURBT

Q

Consent for TURBT

A

Confirm patient details. Ensure comfortable.
Indication - Diagnostic/Treatment
Depending on size of resection - day case versus overnight stay

Risks:
Bleeding, Infection, Pain, Lower Urinary Tract Symptoms
Damage - Bladder perforation, Urethra
Urethral stricture in future
Will need a catheter after procedure - ?1 day ? 2 weeks if concerns of bladder perforation/ urethral trauma
May need further procedure - Re-do TURBT if incomplete resection, Surveillance cystoscopies in future
Anaesthetic Risk

Instillation of intravesical mitomycin post procedure - GIve mitomycin within 6 hours of operation (ideally within 60 minutes)

NICE NMIBC:
Low Risk
G1/G2 (LG) pTa <3cm

Intermediate
G1/G2 (LG) pTa >3cm
Multifocal G1/G2 (LG) pTa
HG G2pTA
Low risk NMIBC Recurring within 12 months

High
G3

Q

When do you offer early re-resection?

What are the benefits?

A
  • G3 or T1 Disease regardless of margins
  • Incomplete resection
  • No Muscle in Sample

Benefits:
- Improved recurrence free survival
- Improved outcomes post BCG
- Provides further prognostic information

Q

When tumour is on lateral wall?

A

Risk of obturator kick

Ask for paralysis
Bipolar Diathermy
Short Bursts with low Current
Don’t overinflate bladder

Q

While resecting you see fat?

What to do

A

Stop - call for help (urology consultant/more experienced surgeon)
Inspect bladder - obtain haemostasis
If concerns regarding intraperitoneal perf - on table cystogram (300 ml 50/50 Contrast, AP and Oblique views firstly with the bladder distended and then once emptied)

If confirmed IP Perf - > Consider laparatomy and bladder repair
If EP perf haemostasis, large bore catheter for 2 weeks, no mitomycin

after the procedure
exercise duty of candour - inform patient, risk of seeding
catheter can be removed after cystogram (at least 2 weeks later)

Q

Risk of progression to muscle invasive disease without treatment - CIS

Risk of progression to MIBC after BCG

A

54% risk of muscle invasive disease without treatment

BCG
Responders - 10-20% Progress to MIBC
Non-Responders - 66% Progress to MIBC

Q

What constitutes BCG Failure vs BCG Refractory Tumour?

A

BCG Failure - MIBC Detection During FU

BCG Refractory:
HG NMIBC present att 3 months (associated with increased risk of disease progression)
CIS Present at 3 + 6 months. (BCG can still induce complete response in >50%)
HG Tumour appears during BCG therapy

Non HG recurrence is not considered BCG Failure

Q

MRI vs CT for bladder Ca

A

MRI - Better for accurate staging of tumours

CT/MRI - Equal in detection of LN

17
Q

CI to neobladder

A

Neurological/Pyshiatric Illness
Limited Life Expectancy
Impaired liver/renal function
TCC of urethral margin
