Renal Flashcards
what is UTI?
infection in the urinary tract
signs and symptoms of UTI
flank pain
high fever
malaise
frequency urgency
dysuria
confusion
rigours
suprapubic tenderness
investigation of UTI
Urine dip test
urine microscopy, culture & sensitivities (MC&S)
first-line treatment for UTI
simple analgesia
encourage intake of fluids
medications:
Nitrofurantoin 100mg
trimethoprim 200mg
Risk factor of UTIs
latrogenic / drugs
behavioural (voiding dysfunction/ recent sexual intercourse)
anatomic / physiologic
genetic
how long you’ll have to check on catheterized patients
if more than 7 days then check for blockage and consider removing the catheter
first line option for UTI in catheterized patients
nitrofurantoin 100mg
trimethoprim 200mg
amoxicillin 500mg
what is cystitis
bladder infection
symtoms of cystitis
increased urinary frequency
urgency
dysuria
pain above the pubic region
WBCs & bacteria in urine
possible hematuria
first-line treatment for cystitis
& alternatives
still nitrofurantoin
fosfomycin
Management on acute urinary retention?
Arrange to hospital admission and urgent catheterization and investigation of the cause
what drugs can be used to prevent or manage recurrent urine retention?
Alpha-blocker:
(Alfuzosin 10mg a day)
Pyelonephritis
- what is it?
- cause of it?
- symptoms?
- management?
infection of the kidney, cause by bacteria from the bladder
- Escherichia. coli (60-80%)
Klebsiella species (20%)
Proteus mirablis (15%) - unilateral flank pain
fever
nausea and vomiting - cefalexin 500mg
co-amoxiclav 500/125mg
trimethoprim 200mg
ciprofloxacin 500mg
Alternatives treatment if ceftriaxone is not available for pt that has pyelonephritis
piperacillin / tazobactam
Describe glomerulonephritis and treatment
inflammation of the glomeruli in the kidneys
treatment - supportive care and immunosuppression (corticosteroids)
Types of glomerulonephritis
–> IgA nephropathy (burger’s disease)
- primary glomerulonephritis
- igA deposits and mesangial proliferation
–> Membranous nephropathy
–>Membranoproliferative glomerulonephritis (or mesangiocapillary glomerulonephritis)
–> Post-streptococcal glomerulonephritis
–> Rapidly progressive glomerulonephritis
–> Goodpasture syndrome
Investigation and treatment of glomerulonephritis
renal biopsy
- supportive care
- immunosuppression (corticosteroids)
Nephritic syndrome
- describe the term
- features
inflammation in the kidneys
- haematuria
- oliguria (reduced urine output)
- proteinuria (LESS than 3g per 24 hrs)
- fluid retention
Nephrotic syndrome
- describe the syndrome
- features
- predisposes factors
- causes
- basement membrane in the glomerulus becomes highly permeable, result significant proteinuria
- proteinuria (MORE than 3g in 24hrs)
- Low serum albumin (less than 25g per litre)
- peripheral oedema
- hypercholesterolaemia
frothy urine - thrombosis, hypertension and high cholesterol
- membranous nephropathy, focal segmental glomerulosclerosis
Renal colic
1. what is it?
2. common cause of stones
3. complications?
4. S&S
5. investigations
6. management
1) Urinary stone causing obstruction to the flow of urine and leading to loin pain
2) calcium oxalate stones (80%)
calcium phosphate stones (20%)
3) obstruction of urinary flow and infection
4) dysuria, urinary frequency, straining
5) Urine dipstick test
adults - low-dose non-contrast CT
pregnant - ultrasound
6) SNAID / IV paracetamol
<5mm - monitor
>5mm - medical expulsive therapy
shockwave lithotripsy (SWL)
Percutaneous nephrolithotomy (PCNL)
Ureteroscopy (URS)
Acute Kidney injury (AKI)
- symptoms and signs
- risk factors
- stages of AKI
- Examination and investigations
- management of AKI
- types of AKI
- N&V, diarrhoea, suspected dehydration, reduced urine output/ change to urine colour, confusion, fatigue / drowsiness
- Age >65, History of AKI, CKD, cardiac failure, DM, sepsis, Hypovolaemia, nephrotoxic drug use (NSAID), contrast agents
- Stage 1 ) >/= 26.5 mol/L & <0.5ml/kg/hr 6-12hrs
Stage 2 ) >/= 2-2.9 x baseline & <0.5ml/kg/hr >12hrs
Stage 3 ) >/= 353.6 mol/L / x3 reference & <0.3ml/kg/hr 24hrs / Anuria for > 12hrs - Blood test, Blood cultures, Urine output, dip and M,C&S, Blood gas, chest X-ray, ECG
- treat hypovolaemia and correct electrolyte imbalances
- Pre-renal, intra-renal, Post-renal
