diagnosis

Cytoscopy
histopathology
grading
high grade
well differentiated
low grade
poorly differnentiated
staging
stage 0
cis
flat on the mucosal linning
Papillary 0a
Papillary on mucosal linning
stage 1
invades the submucosa
stage 2
invade the muscle layer
stage 3
invades the surrounding fat
stage 4
invade the surrounding tissues
cytology
Detect highly malignant cells (like CIS)
schistoma hematobium egges
Papillary varient
lab investigations
PSA
test for prostatic cancer and BPH
can cause UTI symptoms
normal level: up to 4ng/ml of blood
other investigations were disscussed in details in previous PBL's

radical cystectomy

Physiology of micturation
during bladder filling
sympathetic (L1-L3) dominate
Relax detrusor muscle
stimulate the internal sphincter
during bladder emptying
parasympthatic (S2-S4) dominate
contract detrusor muscle
inhibit the internal sphincter
there must be somatic relaxation of external sphincter in order of voiding to happen
by pudendal nerve (S3-S4)
epidemiology
MC malignancy in UTI
9th MC malignancy
types
urothelial
in america and europe
MC risk factor: smoking
non-urothelial
in middle east
MC risk fsctor: schistosoma hemabotium
A cestode parasitic infection
increases carcinogen-metabolizing enzymes
+++N-nitrosamines
alkylating DNA damage
metaplasia and carcinoma
