25
Patients under 45 with macroscopic haematuria in the absence of infection also need what
a cystoscopy and upper tract imaging
26
Patients under 45 with microscopic haematuria do not need urological investigation unless then have what symptom In this case what should they have.
loin pain should have a non contrast CT of the urinary tract to rule out stones As part of this they should also have their renal function. BP and urine protein excretion measured.
27
Bladder Cancer: tell me about the epidemiology of it
7th most. common cancer in the UK 3-4 times more common in men than women majority of cases occur in over 60s
28
what are the main risk factors for bladder cancer
- increasing age - smoking - exposure to Carcinogens include aromatic amines, polycyclic aromatic hydrocarbons, arsenic and tetrachloroethylene (These are found in hair dyes, industrial paint, rubber, motor, leather, and rubber workers, blacksmiths etc.) - Schistosomiasis causes squamous cell carcinoma in countries with a high prevalence - Drinking sufficient water is thought to be protective
29
What is your stereotypical exam question patient who has bladder cancer present
Typical exam question is a “dye factory worker with painless haematuria”
30
What are the main types of bladder cancer
90% transitional cell carcinoma 10 % squamous cell carcinomas Rarer causes are adenocarcinoma, sarcoma, small cell.
31
How do patients with bladder cancer usually present
visible painless haemturia but also microscopic haematuria, irritative. urinaryy. symptoms or UTIs that don't respond to appropriate antibiotic treatment
32
what percentage of bladder cancers do not affect the muscle wall of the bladder
75-80%
33
How are bladder cancers that do not affect the muscle wall removed
telescopic removal by transurethral resection of the bladder tumour aka TURBT
34
Patients with superficial invasion of the bladder wall (stage T1) or histologically aggressive disease (grade. 3) require what therapy into the bladder
BCG therapy into the bladder.
35
What do all patients with bladder cancer require
prolonged telescopic checking of the bladder (cystoscopy) as a follow up
36
Patients with cancer in ____________ cannot be cured with TURBT orBCG. and these patients are offered either a radical cystectomy or radiotherapy
the muscle wall
37
``` What does the staging of bladder cancer mean; Stage Tis Ta T1 T2 T3 T4 ```
Tis - carcinoma in situ ie hasnt moved from where it originated Ta- tumour confined to the epithelium T1- tumour in submucosa connective tissue or lamina propria T2- invades muscle T3- extends into perivesical fat T4- invades adjacent organs
38
What is the usual treatment for a Tis, Ta or T1 stage transitional cell carcinoma (TCC)
TURBT and BCG
39
What is the usual treatment for a T2-3 TCC
Radical cystectomy is the gold standard as radiotherapy. gives worse 5 year survival rates but preserves the bladder
40
What is the usual treatment for T4 TCC
Palliative chemo/radiotherapy | Chronic catheterisation and urinary diversions may help to relieve pain
41
What is the follow up period for high risk tumours
every 3 months for 2 years and then every 6 months
42
What is the follow up period for low risk tumours
first follow up in 9 months then every year
43
Bladder cancer grading; | what does grade 1, 2 and 3 mean
grade 1 is the least aggressive/most well differentiated histologically grade 2 is intermediate grade 3 is most aggressive/least well differentiated histologically
44
What are the symptoms and signs of renal colic due to a stone obstructing the ureter
loin to groin pain, very severe and of a colicky nature Nausea and vomiting occasionally LUT symptoms (frequency, urgency) is stone is in lower ureter Haematuria (but usually non-visible so not a symptom) Signs of tachycardia, dehydration but should not be pyrexial or have localised peritonism
45
What are some common differentials for renal colic
o Urological: Pyelonephritis (infection of the kidney usually caused by bacteria travelling up from the bladder) o Gynae: ectopic pregnancy, torted ovarian cyst o Gastro: Appendicitis, diverticvulitis o HPB: pancreatitis, cholecystitis o Vascular: ruptured AAA o MICS: Musculo-skeletal pain
46
What is the most common type of renal stone and then name the other types
most common is calcium oxalate 65-80%- oxalate is a byproduct found in various food types other ones are calcium phosphate 10-15% struvite (triple phosphate) - stag horn 10-15% Uric acid 5-10% cystine 1%
47
what diagnostic tests should be carried out in someone with renal colic
``` bloods: FBC, U&E, calcium/CRP Urine: 85% +ve haematuria and to exclude UTI and pregnancy (bHCG) Non constrast CT scan of abdo/pelvis 70% of stones are visible on KUB x ray ultrasound may reveal hydronephrosis ```
48
Name some differentials to Haematuria and bilateral flank pain
• Renal stone disease o Stones, obstruction, infection • Renal tumours o Benign tumour eg angiomyolipoma (AML) o Malignant tumour eg renal cell carcinoma • Infection • Trauma (eg biopsy) • Enlarged kidneys o Polycystic kidney diseases (eg ADPKD) o Obstruction (eg papillary necrosis, ureteric/bladder tumour) • Glomerular haematuria (IgA nephropathy)
49
what does colic pain more likely to suggest
obstruction of the urinary. tract
50
what does a dull ache pain more likely to suggest
something to do with within the kidney or stretching of the renal capsule
51
What are NSAIDs associated with
papillary necrosis
52
In someone presenting with haematuria and flank pain what things to you want to ask in the history
* Pain (colic pain is more likely to be obstruction of the urinary tract. Dull ache then this suggests more likely to be within the kidney or stretching of the renal capsule) * Fevers * Weight loss * Smoking * Occupational exposure eg dyes * Medications (aspirin, NSAIDS associated with papillary necrosis. Cyclophosphamide predisposes to malignancy) * Past history (HTN, TB, DXT, procedures) * Family history (ADPKD, VHL, TS)
53
What is a KUB x ray
a kidney, ureter and bladder x ray
54
Name some ways to image in someone who presents with loin pain
``` plain X ray (KUB) intravenous pyelogram (IVP) Ultrasound (USS) CT scan (CT urogram) MRI Angiography ```
55
What are the main causes of urological stones
50% are metabolic such as type 1 renal tubular acidosis, hyperparathyroidism, cystinuria, sarcoidosis, chrons (enteric hyperoxaluria) urological 20% infection 20% immobilisation 5%
56
What is cystinuria
inherited disease that causes stones made of the amino acid cystine to form
57
what is sarcoidosis
causes granulomas to form in the organs of the body, mainly skin and lungs
58
What are most stones made of
75% calcium oxalate 10% struvite "staghorn" 10% Urate (radiolucent)

What is the medication management of stones
increasing fluid intake to reduce solute load dietary modification- decrease animal protein, Na, sugar and oxalate treat infection alklanlinse urine Specific medical therapy
60
What is the medical therapies used to treat the following Hypercalciuria hyperuricosuria cystinuria answers are Allopurinol Penicillamin Bendroflumethiazide
 Bendroflumethiazide (hypercalciuria)  Allopurinol (hyperuricosuria)  Penicillamine (cystinuria)
61
What are the main types of kidney tumours
Benign: Angiomyolipomas and oncocytoma Malignant: Renal cell carcinomas (80%) and transitional cell carcinomas.
62
Tell me about transitional cell carcinoma
common and present in any part of the urinary tract Presentation is haematuria, pain and LUTs Commonly in over 45 o Smoking, cyclophosphamide, radiotherapy, occupational exposure, schistosomiasis infection previously
63
What is papillary necrosis and what are the risk factors
``` necrosis and shredding of the medullary papillae risk factors are; o Analgesia (acetaminophen, NSAID) o Diabetes o Sickle cell disease o Infection ``` need urgent drainage and antibiotic treatment is essential
64
What is the commonest genetic renal disease
ADPKD- autosomal dominant polycsytic kidney disease
65
What extra renal symptoms develop from the ADPKD
(berry aneurysms, liver, pancreas, spleen cysts, mitral valve prolapse, diverticuli)
66
What is the usual complications associated with ADPKD
high morbidity secondary to CVD | blood pressure control from childhood is essential
67
What is the management of ADPKD
family screening monitoring renal function and kidney size possible therapies under trial are vasopressin antagonist somastatin analogues there is NO role for SURGERY/DECOMPRESSION
68
what's bergers disease
this is IgA nephropathy where IgA lodges in your kidney
69
What is urine cytology and in what patients is it reserved for
