Renal Flashcards
What are clinical signs of adequate RRT?
Volume status (pulse, bp, jvp, chest, oedema)
Asterixis (metabolic encephalopathy)
Excoriation marks
RR (resp compensation for metabolic acidosis)
Pericardial rub (uraemia pericarditis)
What are complications of HD?
Removal of fluid too quickly +/- too much - hypotension, cramps, headache Bacteriaemia if through tunnelled line Bleeding from heparin Dialysis related amyloidosis Fistula problems Dialysis disequilibrium syndrome
What are complications of PD?
Bacterial peritonitis Catheter exit site infections Kinking of tube due to constipation Peritoneal sclerosis Pleuroperitoneal leak due to diaphragmatic defect
What complications can occur with a fistula?
Aneurysm or pseudo aneurysm
Thrombosis (no thrill or bruit)
Steal syndrome
Stenosis (consider a fistula gram)
What are the manifestations of renal osteodystrophy?
Osteitis fibrosa
- increased bone turnover due to secondary hyperparathyroidism, bone cysts occur
Adynamic bone disease (bone turnover reduced)
Osteomalacia
What is the definition of nephrotic syndrome?
Hypoalbuminaemia
Heavy proteinuria (>3G/24hrs)
Oedema
What is the differential for nephrotic syndrome
Minimal change (idiopathic, assoc with DM, IgA nephropathy, HIV, paraneoplastic
FSGS (idiopathic, hiv, obesity, NSAIDs)
Membranous (infection; hep B/C, malaria, autoimmune; SLE, RA,
Paraneoplastic, drugs)
Mesangiocapillary GN
What are the complications of NS
Oedema (salt, diuretics) HTN Hypercholesterolaemia Thrombosis Infection
What are the clinical features of PCKD
FHx + diffuse cysts + enlarged kidneys
Asymptomatic or
Infection/stones/HTN or pain from cysts
Maybe hepatomegaly from cysts
What are extra renal manifestations of PCKD
Associated with MV prolapse, AR
Intracranial aneursyms
Liver cysts
How do you manage PCKD
Manage HTN and address CV RFs Screen for intracranial aneursyms if high risk Consider tolvaptan (vasopressin receptor 2 antagonist)
What diseases cause bilateral renal cysts
PCKD
Multiple simple cysts
VHL syndrome
Tuberous sclerosis
What are the absolute CIs to kidney donation
Diabetes Uncontrolled HTN or evidence of end organ damage Active Ca Unable to consent Acute symptomatic infection
How do you assess acute allograft dysfunction
Calcineurin levels MSU FBC Signs of HUS USS, urine cytology Renal biopsy
What are the causes of allograft dysfunction
Volume depletion Rejection Calcineurin toxicity Ureteric problem Post 4 weeks: infection: CMV, BK PTLD, lymphoma
