Urine dipstick - to rule out infection

Q

What are the medial drugs used to prevent kidney stones?

A

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

Q

What is the management of kidney stones dependant on size?

A

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

Q

Why are UTIs more common in women post menopause?

Q

How would you investigate a UTI?

A

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)

16
Q

What is the treatment for lower UTIs?

A

3 day course of antibiotic

Usually trimethoprim, cephalexin or nitrofurantoin

17
Q

What is the treatment for pyelonephritis?

A

24-48 hours IV gentamicin or temocillin

Followed by 10 day course of oral antibiotics

18
Q

Define recurrent UTIs?

How would you treat them?

A

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

19
Q

How are Tis/Ta/T1 bladder cancers treated?

A

Transurethral resection of the bladder tumour (TURBT)

If tumour is histologically aggressive (grade 3) then they also require BCG therapy

20
Q

What are the different TMN staging of bladder cancer?

A

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

21
Q

How are T2/T3 bladder cancers treated?

A

Radical cystectomy

Also can offer radiotherapy but gives 5year worse survival rates

22
Q

What type of cancer is bladder cancer?

A

Transitional cell carcinoma (TCC)

23
Q

What are the symptoms of BPH/Prostate Cancer?

A 
Nocturia 
Hesitancy
Poor stream 
Terminal dribbling 
Obstruction 
Weight loss or bone pain suggest mets
24
Q

How is prostate cancer diagnosed?

A

PSA raised
Transrectal USS & biopsy
X rays
Bone scan for mets

25
Q

What type of cancer are the majority of prostate cancers?

A

Adenocarcinoma

26
Q

Where abouts are the majority of prostate cancers?

A

70% in the peripheral zone

27
Q

How are prostate cancers graded?

A

Using the Gleason grading system (2-10)

2 is best prognosis, 10 is the worst

28
Q

When is active surveillance the preferred option in prostate cancer?

A

Low risk men e.g, T1c, Gleason score of 6, PSA <0.15ng/ml/ml
Cancer in less than 50% of biopsy cores
In elderly patients
In patients with multiple co morbities

29
Q

What is the treatment for localised prostate cancer (T1/T2)?

A

Conservative monitoring
Radical prostatectomy
Radiotherapy: external beam and brachytherapy

30
Q

What is the treatment for metastatic prostate cancer?

A

Hormonal therapy with synthetic GnRH agonist (Goserelin)

This provides negative feedback to the anterior pituitary

31
Q

What are the age adjusted upper limits for PSA?

A

50-60 : PSA - 3.0ng/ml
60-70 : PSA - 4.0ng/ml
70-80 : PSA - 5.0ng/ml

However, must refer any man over 50 yrs if PSA >3.0 or if there is abnormal DRE

32
Q

Why might PSA levels be raised?

A 
Prostate cancer
BPH
UTI 
Ejaculation (in previous 48 hours)
Vigorous Exercise (in previous 48 hours)
33
Q

What should be co prescribed alongside goserelin (Zoladex) for prostate cancer in the first few weeks of treatment and why?

A

Cyproterone acetate

It is an anti-androgen treatment so prevents the risk of tumour flare

BNF advices starting cyproterone acetate 3 days prior to GnRH analogue

34
Q

What are the post operative complications of radical prostatectomy?

A

Infection
Incontinence
Erectile dysfunction
Urethral stenosis

35
Q

What lifestyle factors are suggested to people with BPH?

A

Avoid caffeine and alcohol to reduce urgency and nocturia
Relax when voiding
Control urgency by practicing distraction methods (e.g, breathing exercises)

36
Q

What medication is used to treat BPH?

A

Alpha blockers - tamsulosin

5alpha reductase inhibitors - finasteride

37
Q

If a patient presents with UTI like symptoms as well as being septic and having loin pain, what investigation would you do?

A

Urgent upper tract ultrasound

To look for pyonephrosis

38
Q

What is the criteria for a 2ww urology referral?

A

Any patient over 45 with unexplained visible haematuria without UTI
Any patient over 60 with unexplained microscopic haematuria
Any main with raised PSA or abnormal feeling prostate
Any man with a testicular mass or possible penile cancer
