Genitourinary Flashcards
KIDNEY CANCER
What Type accounts for 90% of cases?
Renal cell carcinoma
KIDNEY CANCER
Where does renal cell carcinoma arise from?
Proximal renal tubular epithelium
KIDNEY CANCER
Aetiology?
Loss in 3p chromosome tumour suppressor gene which causes increased expression of epidermal growth factors
KIDNEY CANCER
Risk factors
Smoking
Drinking
Long term dialysis
KIDNEY CANCER
Symptoms?
1) Haematuria
2) Loin pain
3) Abdo pain
4) weight loss
5) anorexia
KIDNEY CANCER
Diagnostic tests?
- incidental ultrasound- 25% will have mets
-10% have classic symptoms
KIDNEY CANCER
How can it spread?
It can spread directly through the renal vein or haematogenously via the blood
Direct- Varicocele
Blood- bone, liver, lung
KIDNEY CANCER
Investigations?
- ultrasound
- CT of chest and abdomen to find mets
- IV contrast CT to check individual renal function
- high blood pressure
- FBC- polycythaemia due to EPO secretion
KIDNEY CANCER
Treatment?
- radical or partial nephrectomy
- Angiogenesis- targeting agents for unresectable tumours/ mets
(Tyrosine kinase inhibitors- Sunitinib and sorafenib if mets)
chemo or radio resistant
KIDNEY CANCER
Prognosis score?
- stage
- size
- grade
- necrosis
BLADDER CANCER
What type accounts for 90% of cases?
Transitional cell carcinoma
There is also squamous cell carcinoma
BLADDER CANCER
What is the cause?
Schistosomiasis (snail fever- parasitic flatworms called schistosomes)
BLADDER CANCER
Risk factors?
- smoking
- alcohol
- schistosomiasis
- aromatic amines from the rubber industry
BLADDER CANCER
How is it graded?
Grade 1 = differentiated
Grade 2 = intermediate
Grade 3 = poorly differentiated
BLADDER CANCER
Common spreads?
Blood- lung, livers
Lymph- iliac & para-aortic nodes
BLADDER CANCER
Symptoms?
Painless and haematuria
Recurrent UTIs
Irritable voiding
BLADDER CANCER
Diagnostic Tests?
Urine analysis- ‘MC&S and cytology
Cystoscopy with biopsy
CT urogram for staging
BLADDER CANCER
Risk groups\?
1) >45 with unexplained visible haematuria
2) >60 with unexplained non visible haematuria
3) Visible haematuria that persists after a UTI
BLADDER CANCER
Staging?
Tis- carcinoma in situ
Ta- just epithelium
T1- lamina propria
T2- superficial muscle involved
T3- deep muscle involved
T4- invasion beyond bladder
BLADDER CANCER
Treatment of Tis/ Ta/ T1 tumours?
1) Transurethral resection of bladder tumour (TURBT)
2) Diathermy
3) Chemo for multiple small tumours
BLADDER CANCER
Treatment for T2/ T3 tumours?
1) Radical cystectomy or radiotherapy as this preserves the bladder
BLADDER CANCER
treatment for T4 tumour?
palliative chemo/ radio + chronic catheter
ACUTE KIDNEY INJURY
Diagnostic criteria/ what is it?
1) Rise in creatinine >26 umol/ L in 48 hrs
2) rise in creatinine >1.5x baseline
3) Urine outpyut <0.5ml/kg/hr for 6 hours
ACUTE KIDNEY INJURY
If there is reduced excretion, what rises?
urea
