transitional cell carcinoma Flashcards
what urological organs does transitional epithelium line
- urinary tract lining
- renal pelvis
- ureter
- bladder
- urethra (up to fossa navicularis in men)
what should be suspected if painless haematuria is present
cancer until proven otherwise
risk factors for bladder cancer
- age
- sex (male)
- smoking
- occupational exposure - rubber/dye manufacture, hairdressers, chemicals, plumbers, painters, drivers (diesel exhuast)
- drugs - cyclophosphamide
- chronic irritation - stones, catheter etc.
- pelvic radiotherapy
bladder TCC presentation (4)
- haematuria
- LUTS
- recurrent UTI
- others e.g. pneumaturia, pain, lower limb swelling, bone pain, anuria
superficial bladder TCC mgx
Trans urethral resection of bladder tumour (TURBT)
T stages for bladder cancer
Ta - non invasive papillary
Tis - Tumour in situ (change in epithelial lining)
T1 - subepithelial connective tissue
T2 - invasion of muscularis
T3 - invasion beyond the muscularis
T4 - invasion of surrouding structures e.g. prostate, uterus, vagina
what can be done for urinary diversion post bladder removal
- ileal conduit
- orthotopic neobladder
- continent pouch
- ureterosigmoidostomy
what is an ileal conduit
diversion of urine to a newly formed opening on the skin through a peice of ileum that has been removed -> urine then collected in a bag
what is an orthotopic neobladder
the creation of a new bladder -> it can be ileal, ileo-colic or colonic (part of the intestine is used to create it)
what is a ureterosigmoidostomy
a surgery that connects the ureters to the sigmoid colon and allows urine to pass out of the body that way
why are ureterosigmoidostomies not performed that much anymore
high risk of problems incl. tumour formation at the sigmoid anastamosis
what information can IVU provide about the renal pelvis
presence of filling defects
where are the majority of TCC cancer found
the bladder
where can an upper tract (i.e. renal pelvis) TCC spread to (what structures)
- direct extension - renal vein and vena cava
- lymphatic spread - para aortic, para caval, pelvic
- haematoganous spread - liver, lung, bones
2 curative treatments for TCC
- nephro ureterectomy (kidney + ureter up to bladder)
- uretero-renoscopic laser ablation
