Q

What is crystalluria?

A
  • Stone formers (especially calcium oxalate stones) frequently excrete more calcium oxalate crystals in the urine
  • Increased urinary excretion of cystine, struvite, and uric acid crystals is also a risk factor for stone formation

Q

What is the difference between renal stone and peritonitis?

A

Flank/ loin to groin pain:

  1. If patient is writhing around in pain = renal stone
  2. If patient is lying still = peritonitis (as move too painful)

Q

What is the management of urinary tract calculi?

A
  1. Analgesia – NSAIDs, Paracetamol (same as opiates in terms of controlling ureteric colic pain)
  2. Increase Fluid intake
  3. Anti-emetics
  4. Tamsulosin (α1- antagonist) or Nifedipine (CCB) – to relax smooth muscle

Q

What must you check for in urinary tract calculi?

Study These Flashcards
A

pregnancy and for infection higher up the tract

17
Q

What are the 3 surgical options for stone removal?

Study These Flashcards
A
  1. Ureteroscopic lithotripsy
  2. Extracorporeal schockwave lithotripsy (ESWL)
  3. Percutaneous Nephrolithotomy (PCNL)
18
Q

What are utis?

Study These Flashcards
A

presence of a pure growth of >10^5 organisms per mL in MSU

19
Q

What is an upper UTI?

Study These Flashcards
A
  1. pyelonephritis (infection of kidney/ renal pelvis)

2. Ureters (ureteritis)

20
Q

What is a lower UTI?

Study These Flashcards
A
  1. bladder: cystitis
  2. urethra (urethritis)
  3. prostatitis in male
21
Q

What are risk factors for UTI

Study These Flashcards
A
  1. Sexual intercourse
  2. Spermicide use
  3. Pregnancy
  4. DM
  5. Obstruction to the urinary tract
22
Q

What is the most common causative agent of uti?

23
Q

What other bacteria is found in utis in immunocompromised people?

Study These Flashcards
A

Klebsiella and candida

24
Q

Why are women more commonly affected by utis than men?

Study These Flashcards
A

shorter urethra

25
How would pyelonephritis present (kidneys)?
1. Fever 2. rigors 3. vomiting 4. loin pain 5. costovertebral pain 6. Cystitis symptoms
26
How would cystitis present? (bladder)
1. FUND: frequency urgency nocturia (elderly), dysuria (storage symptoms) 2. Suprapubic pain 3. Polyuria and haematuria
27
How would prostatitis present?
1. Flu-like symptoms 2. loin pain 3. low back ache 4. Swollen or tender prostate on PR 5. HIPS: hesitancy, intermittent flow, poor stream (obstructive symptoms)
28
What is the first line investigation of UTI?
urine dipstick: - leucocytes: infection - nitrites: presence of bacteria - haematuria
29
What are the other investigations of UTIs?
1. Urine microscopy (can identify organism tyoe 2. Urine culture and sensitivity (more specific and sensitive test- measures growth of colonies) 3. May also consider doing blood tests if patient is systematically unwell or imaging if pt has recurring UTIs
30
What is the prophylactic management of UTIs?
1. high fluid intake 2. regular micturition to keep bladder empty 3. cranberry-based products
31
What antibiotics would you give for cystitis/lower UTI?
1. trimethoprim 2. nitrufuratoin - don’t give trimethoprim in pregnancy as it is a folic acid antagonist (therefore alternative treatment would be using nitrofurantoin)
32
What antibiotics do you give for pyelonephritis?
1. Oral: Cefalexin, or ciprofloxacin. 2. IV antibiotics if unwell such as gentamicin are given – give before result from cultures comes back to prevent deterioration
33
What are the complications for UTIs?
1. Septicaemia 2. AKI 3. Pyelonephritis 4. Confusion (elderly)
34
What are the common types of bladder cancer?
>90% are transitional cell carcinomas in the UK
35
What condition is associated with squamous cell carcinoma?
Schistosomiasis = rare in the West (so is adenocarcinoma)
36
What are the risk factors for bladder cancer?
1. smoking 2. those= hx of working in industrial and manufacturing plants (aromatic amines= risk factor AZO DYES= made up of aromatic amines) 3. chronic cystitis 4. More common in men 5. elderly
37
What is the presentation of bladder cancer?
1. Painless haematuria 2. Recurrent UTIs 3. FUND
38
Why are there no HIPS symptoms of bladder cancer?
does not affect urethra
39
What are the investigations for bladder cancer?
1. Cystoscopy (+urinary cytology key for diagnosis) - GOLD STANDARD 2. US 3. Intravenous urography 4. CT/MRI for staging
