Pros/cons of RRT
Case
A 58 yr old man presents to his GP with a history of
feeling generally unwell and lethargic for six months but
has not sought medical attention until now.
He has reduced exercise tolerance and feels nauseous.
What other questions would you like to ask?

On further questioning you find he complains of:
Puritus resistant to Piriton
Generalised aching in his joints and back
Increased thirst
A yellowing of the skin
Case
On Examination:
BP 160/95
Jaundice with excoriated skin
CV/Resp NAD
What tests would you like to order?

Bloods:
Na: 143 (135-145)
K: 5.8 (3.5-5.2)
Ur: 55 (6-20)
Cr: 398 (60-110)

What would your management plan be?
Aetiology
• PRE-RENAL
– Atherosclerosis
– Heart Failure
– HTN
• RENAL
– Congenital
• PCKD
– Glomerular/Tubular
•
•
•
•
SLE/Vasculitides
Amyloidosis
Drug overdoses
Diabetes
• POST-RENAL
– Outflow tract obstruction
• BPH

PCKD
• COMMON FPE CASE!
•Usually Autosomal, Dominant
•(rarer recessive Childhood PCKD)
•Other organs:
•Liver
•Pancreas
•Heart valves
•Mitral Regurge.
•Aneurysms (CoW)
•SA haemorrhage
History and Examination
• What are the main functions of the
kidney?
1. Excretion
Filtration
2. Elimination
Via the urine
3. Regulation
BP Regulation RAAS
Electrolyte balance
Vitamin D
Calcidiol->Calcitriol
Erythropoietin
History and Examination
Anaemia
Pallor, SOBOE, Malaise and lethargy
Hypertension
Signs of fluid overloading
Excretion
Pruritus, jaundice
Electrolyte imbalance
Potassium
Sodium
Headaches, nausea
# due to osteomalacia
Urinary symptoms
Ask about immunosuppressants
Don’t forget...
• In the OSCE, do not forget to look and feel for
1. A/V Fistulae
2. Renal Transplant scar/organ
Investigations
• Bedside
– ECG (CV disease)
– Urine dip
• Bloods

U&E’s and eGFR
FBC
ESR (Long term inflammation)
Calcium (down)
Phosphate (up)
Urate (up)
• Imaging
– USS
– CT KUB
– X-ray (Chest, abdo)
• Biopsy
Investigations- eGFR

1. Age

3. Race
4. Serum Creatinine
Management...Conservative
Reduce dietary sodium
Reduce dietary potassium
Management...Medical
EPO
Antihypertensives (ACEI, diuretic, CCB)
Calcium supplements (PO4 binders)
Vitamin D
RRT
-Haemodialysis
-Peritoneal dialysis
-Haemofiltration
-Transplantation
Dialysis
Haemodialysis
Semi-permeable membrane
Time consuming
Travel to hospital
Requires AV fistulae
Peritoneal Dialysis
Permanent catheter
3L of fluid; uncomfortable
Higher infection risk (SBP)
Transplant
