Renal Long Flashcards
Causes of CKD
- DM - 33%
- GN - 24%
- HTN - 14%
- PCKD - 7%
- Reflux nephropathy
- Analgesic nephropathy
- Uncertain
RF for progression of CKD
- Low birth weight
- HTN
- AKI
- Proteinuria
- Smoking
- Hyperuricaemia
- An increase in glomerular pressure (pregnancy, obesity, diabetes)
Early Sx of renal failure
Nocturia Lethargy Loss of appetite Fluid retention Pruritis
Sx of Severe CKD
Pericarditis Serositis Encephalopathy GI bleeding Uraemic neuropathy
Precipitants of AKI
NSAIDS Contrast Infection ACE/ARB Dehydration Anaemia
Sx/Signs to screen for GN
Proteinuria Haematuria Oliguria Oedema Sore throat Sepsis Rash Haemoptysis
IgA nephropathy associations
HIV
CLD
IBD
Coeliac
Causes of membranoproliferative GN
Hep C Autoimmune disease Indolent infections (malaria, syphilis) Essential Cryoglobulinaemia Malignancies Drugs - penacillamine, NSAIDS, anti TNF drugs Mercury/gold poisoning
Causes of FSGS
Primary Familial HIV infection Morbid obesity Heroin use Reflux nephropathy
PCKD Hx Questions
FHx Haematuria Polyuria Loin pain HTN Renal calculi Headache/SAH/visual disturbance Diverticular disease Hernias
Principles of Mx of CKD
- Fluid intake and diet
- Anaemia
- Acidosis
- Phosphate/calcium/bones
- CVS risk
- Consider vascular access
- Consider when to start dialysis
- Consider suitability for Tx
General Dialysis questions
- Where is it performed
- How often
- How many hours per week
- Relief of Sx with treatment
- Complications with dialysis
- On transplant list
CKD conservatively managed patients - Sx questions
Anaemia Bone disease Secondary gout/pseudogout Pericarditis HTN Cardiac failure Fluid overload Peripheral neuropathy Pruritis Peptic ulcers Impaired cognitive function Poor nutrition
HDx History questions
How long have they been on HDx?
Where do they dialyse? - Transport if satellite unit
What is the current dialysis prescription?
-Frequency, duration, dry weight, fluid removed
-Pre and post HDx BP
-Anticoagulation apart from heparin given during HDx
-Recent changes to presciption
What is the patient’s dialysis access Hx?
Any symptoms on or after dialysis?
PDx Hx Questions
CAPD vs APD?
How long have they been on PD
Infections of PD side or peritonitis
Still passing urine?
Renal Tx Questions
- Graft pain or swellin
- Infections
- Urine leaks
- Steroid and immunosuppression side effects
- Proteinuria and Cr level
- Avascular necrosis
- Skin cancer
- Reflux nephropathy
- Recurrent GN
CKD causes that have normal or enlarged kidneys
- Early diabetic nephropathy
- PCKD
- Obstructive uropathy
- Acute renal vein thrombosis
- Amyloidosis
- Rarely other infiltrative diseases eg. lymphoma
CKD Ix
- Determine renal function
- egfr
- Tubular function: electroltes, pH, uric acid, calcium, albumin
- Urinalysis and PCR - Determine renal structure
- USS - size and symmetry, signs of obstruction
- Renal artery doppler
- CT - RAS, obstruction, CT renal angiography
- Cystoscopy and retrograde pyelography - Effects of CKD
- FBE, Iron studies, CMP, PTH
- Nerve conduction studies - Assess for underlying disease
- ANA, ANCA, Hepatitis, HIV, complement, SPEP, FLC, urine cytology
- Renal Bx
