Urology Flashcards
(202 cards)
what are the common causes of LUTS in men?
BPH
UTI
Urological malignancy
detrusor muscle weakness/ instability
chronic prostatis
urethral stricture
external compression e.g. pelvic tumour, faecal impaction
neurological disease e.g. MS, spinal cord injury
what are the common causes of LUTS in women?
UTI
menopause
urologicla malignancy
detrusor muscle weakness or instability
urethral stricture
external compression e.g. pelvic tumour
neurological diesase e.g. MS, spinal cord injury
lifestyle factors that affect LUTS?
drinking fluids late at night
excess alcohol intake
excess caffeine intake
which LUTS are storage symtpoms?
inc urinary frequency
nocturia
urgency
urge incontinence
which LUTS are voiding symptoms?
hesistancy
poor flow
terminal dribble
feeling of incomplete emptying
which medicatiosn are known to exacerbate LUTS?
anticholinergics
antihistamines
bronchodilators
investigations for LUTS?
urinalysis
post void bladder screening and flow rate
FBC, U&E and PSA
urodynamic studies
cystoscopy
what conservative measures are available to manage LUTS?
regulating fluid intake
pelvic floor exercises
bladder training techniques
pharmacological management options in LUTS?
anticholinergics (oxybutin, tolterodone) for overactive bladder
B3 adrenergic agonist (finasteride) for overactive
alpha blockers (alfuzosin tamsulosin) for BPH
5a-reductase inhibitors (finasteride) for BPH
Loop diuretics (furosemide, bumetanide) for nocturia
acute urinary retention is most prevelant in which patient population?
elderly men
common cause of acute urinary retention?
BPH
urethral strictures, prostate cancer
UTI- can cause urethral sphincter to close
constipation- compression to urethra
medications e.g. anti-muscarinics
presentation of a patient with acute urinary retention?
acute suprapubic pain
inability to micturate
palpable distended bladder
associated fevers/ rigors may indicate infective cause
which exam is always done when investigating acute urinary retnetion in elderly men?
PR exam to assess any prostate enlargement or constipation
which investigatiosn are avaible for acute urinary retention?
post voidal bladder scan- reveal vol of retained urine
routine bloods: FBC, U&Es, CRP
CSU (if post catheterisation)
what can happen following acute urinary retention that causes high intra-vesicular pressure?
hydronephrosis- urine backs up from baldder and ureters into kidneys, impairing kidnet clearance level
what management is available for acute urinary retention?
immediate urethral cathetirisation
treat underlying cause i.e. BPH
check CSU for infection and treat w antibiotics if necessary
what complication can occur in patients following acute-on-chronic retention resolved through cathetierisation?
(large retnetion volume >1000ml)
post-obstructive diuresis
kidneys can over diurese due to loss of their medullary concentration gradient which can take time to re-equilibrate
post-obstructuve diuresis can cause which further complication?
worsening AKI
patients should have urine ouput monitored 24hrs post-catheterisation. If producing >200ml/hr should have 50% or urine output replaced with IV fluids
what is TWOC?
Trial without catheter
following retention- if patient can void with minimal residual volume considered succesfull
if patient re-enters retention they require re-catheterisation
main complications of urinary retention?
AKI which can lead to chronic kidney injury
inc risk of UTI
renal stones due to stasis
common causes of chronic urinary retention?
BPH in men
pelvic prolapse/ pelvic masses in women
neuoroligcal causes e.g. MS, parkinsons
how do patients in chronic urinary retention present?
painless urinary retention
may have assoc voiding LUTS such as poor flow, hesitancy
overflow incontinence may be present
palpable distended bladder on examination
what management is required following chronic urinary retention?
catheterisation
monitor for post-obstructive diuresis
TWOC
Intermittent self catheterisation
Haematuria can be classified into which categories?
Visible haematuria (macroscopic or gross)
Non-visible haematuria (microscopic or dipstick +ve)
can be symptomatic non visible (s-NVH) or asymptomatic (a-NVH)
