Q

What is a partial nephrectomy?

A

A partial nephrectomy involves the excision of the lesion without comprising the entire organ, given that kidney function is impaired.

Q

What is the most common form of bladder cancer?

Study These Flashcards
A

Transitional cell carcinoma

21
Q

What are the three causes of bladder cancer?

Study These Flashcards
A

TCC
Squamous cell carcinoma
Adenocarcinoma

22
Q

Which is squamous cell carcinomas of the bladder common in Egypt?

Study These Flashcards
A

Since schistosomiasis is endemic

23
Q

What type of variants of bladder cancer is common?

Study These Flashcards
A

Non-muscle invasive tumours

24
Q

How are high grade tumours of the bladder shown?

Study These Flashcards
A

Flat or in-situ, there are difficult to visualise

25
What treatment for muscle invasive bladder cancer is available?
Radical cystoprostatecetomy
26
What are the risk factors for bladder cancer?
``` Smoking (Tobacco) exposure Male gender Age>55 years Exposure to chemical carcinogens Pelvic radiation Systemic chemotherapy ```
27
What are the clinical features of bladder cancer?
Painless haemturia Persistent microscopic haemturia --> Red flag (microscopic haematuria is detected using a urine dipstick) Suprapubic pain Lower UTI symptoms - increased frequency of urination Metastatic disease symptoms - bone pain, lower limb swelling, compressional lymph nodes
28
What investigations are conducted in a patient with bladder cancer?
* Flexible cystoscopy * CT urogram * Renal function
29
What does Ta suggest for bladder cancer staging?
Non-invasive papillary carcinoma
30
What does Tis suggest for bladder cancer staging?
Carcinoma in situ
31
What does T1 suggest in a patient with bladder cancer?
Invades sub-epithelial connective tissue
32
A T2 bladder cancer stage suggests what?
Invades muscularis propria
33
What treatment is conducted in a patient with an initial tumour of the bladder?
A transurethral resection of the bladder - using heat to ablate the visible tumour Provides histology and is curative
34
How is a non-muscle invasive tumour treated?
Low grade - and no CIS then consideration of cystoscopic surveillance BCG vaccine
35
How can a BCG vaccine treat bladder tumours?
Elicits inflammatory response to reduce the risk of the progression of bladder lesion cancer
36
What options are available for a patient with a muscle invasive bladder tumour?
``` • Cystectomy • Radiotherapy • +/- chemotherapy • Palliative treatment -In situ red patches in the bladder are a poor prognostic factor. ```
37
What marker is elevated in patients with prostate cancer?
PSA - prostate specific antigen
38
Under what circumstances i PSA elevated?
Elevated in UTI and prostatitis
39
What is the recommended investigation for prostate cancer?
MRI prior to biopsy testing
40
What type of score is given for diagnosis the extensiveness of prostate cancer?
Gleason score
41
What does a 4+3 tumour suggest?
More likely to grow bilaterally and spread
42
What risk are associated with a prostatectomy?
The prostate contains the proximal sphincteric unit – controls degree of urinary continence. • A prostatectomy removes the proximal urethral sphincter  Inadvertent damage to the cavernous nerve to the prostate (neural innervation to the bladder and urethra)  bladder function is affected. • Urethral length changes during operation  Affects continence • Erectile dysfunction
43
What is the main treatment for incontinence induced by a prostatectomy?
pelvic floor muscle exercises | Artificial urinary sphincter device if exercises fail
44
What treatment is available for young and fit patients with a high grade cancer?
Radial prostatectomy
45
What treatment is available for a patient with a low grade cancer?
Active surveillance (regular PSA, MRI and Bx)
46
What follow up investigations are conducted to monitor a post-prosatectomy?
Monitor PSA (should be undetectable)
47
What PSA level indicates a prostate cancer relapse?
>0.2ng/ml
48
What treatment is available for a patient who is unfit and has a high grade cancer?
Hormone therapy
49
What treatment is available for a patient with erectile dysfunction?
Viagra, or prostaglandin E1 and if insufficient - penile prosthesis
