Case 14 - Bladder Cancer/Prostate Disease Flashcards
What are the common causes of haematuria?
UTI
Nephrological causes
Urinary tract stone disease
Cancer - bladder cancer, upper tract urothelial cancer, renal cancer and prostate cancer
How does bladder cancer commonly present?
Painless haematuria
Recurrent UTIs
Voiding irritability
How would you investigate someone presenting with painless visible haematuria?
Urine dipstick - to rule out infection
U&E - investigate renal disease
Flexible cystoscopy - to rule our bladder tumour
CT urogram - to exclude renal and ureteric tumours and stone disease
PSA (in men) - to rule out prostate cancer
What are the risk factors for bladder cancer?
Male sex (3-4x more common in men) Smoking Occupational exposure to (rubber industry) (anlinine dye industry) Chronic cystitis Schistosomiasis
What is the difference between macroscopic and microscopic haematuria?
Macroscopic - is gross/frank/clots
Microscopic - you cannot see (<5RBC per high power field)
What are the main different types of kidney stones?
Calcium oxalate (75%)
Struvite/triple phosphate (10%)
Urate (10%)
What is the typical presentation of Urinary tract calculi (renal stones)?
Renal colic pain - loin to groin spasm pain with nausea/vomiting
Obstructive pain - pain depends on place in obstruction
UTI (may co exist)
Haematuria
Proteinuria
What are the medial drugs used to prevent kidney stones?
Bendroflumethiazide - used to treat calcium stones as decreases the amount of calcium excreted in urine
Allopurinol - used to reduce urate stones
Penicillamine - used to reduce cysteine stones
What is the management of kidney stones dependant on size?
Conservative management: <5mm, lower ureter, no obstruction
Medical expulsive therapy - nifedipine or tamsulosin to promote expulsion
If they still do not pass then try extracorporeal shockwave lithotripsy (ESWL) - ultrasound waves shatter stones
Can also do keyhole surgery to remove stones when large, multiple or complex
How is autosomal dominant polycystic kidney disease managed (ADPKD)?
Monitor renal function (kidney size)
Family screening
Blood pressure control
Pain relief
What is Von hippal lindau syndrome?
Inherited disorder characterised by abnormal growth of both benign and cancerous tumour and cysts in the kidneys, pancreas and genital tract
How do patients with a lower UTI usually present?
Increased frequency Increased urgency Dysuria Frank haematuria Feeling systemically unwell
How do patients with an upper UTI present?
Symptoms of lower UTI first (frequency, urgency, dysuria)
Followed by gradually increasing loin pain that is usually unilateral
Patient is often pyrexial
Patient feels systemically unwell
Why are UTIs more common in women post menopause?
Altered hormone conditions cause alteration in normal vagical bacterial flora
How would you investigate a UTI?
Urine dipstick - look for nitrate, leucocytes, blood and protein
Send MSU sample to lab for microscopy, culture and sensitivity analysis (this takes 48 hours)
If suspected upper UTI take blood cultures and have CT/ultrasound to exclude pyonephrosis (as this can cause sepsis)
What is the treatment for lower UTIs?
3 day course of antibiotic
Usually trimethoprim, cephalexin or nitrofurantoin
What is the treatment for pyelonephritis?
24-48 hours IV gentamicin or temocillin
Followed by 10 day course of oral antibiotics
Define recurrent UTIs?
How would you treat them?
More than 3 episodes of infection per year
Long term low dose prophylactic antibiotic
Take one antibiotic after sexual intercourse if this is the causing factor
How are Tis/Ta/T1 bladder cancers treated?
Transurethral resection of the bladder tumour (TURBT)
If tumour is histologically aggressive (grade 3) then they also require BCG therapy
What are the different TMN staging of bladder cancer?
Tis - carcinoma in situ
Ta - tumour confined to epithelium
T1 - tumour in Lamina propria
T2 - tumour cells in superficial bladder wall muscle
T3 - tumour cells in deep bladder wall muscle
T4 - invasion beyond bladder e.g, prostate or uterus
How are T2/T3 bladder cancers treated?
Radical cystectomy
Also can offer radiotherapy but gives 5year worse survival rates
What type of cancer is bladder cancer?
Transitional cell carcinoma (TCC)
What are the symptoms of BPH/Prostate Cancer?
Nocturia Hesitancy Poor stream Terminal dribbling Obstruction Weight loss or bone pain suggest mets
How is prostate cancer diagnosed?
PSA raised
Transrectal USS & biopsy
X rays
Bone scan for mets
