(38 cards)
What is nephritis?
Inflammation of the kidneys.
What is glomerulonephritis?
Inflammation of the glomerus.
What is pyelonephritis?
Inflammation of kidney associated with a bacterial infection.
What does azotaemia mean?
An increased amount of nitrogenous waste in the blood.
What are the main functions of the kidney?
Produce renin.
Filter waste from the blood & combine with excess water to from urine.
Homeostasis.
Fat soluble vitamin D.
Produce erythropoietin.
What are the two types of renal disease?
Acute - sudden onset, complete/almost cessation of renal function.
Chronic - progressive loss of functional tissue.
What is acute kidney injury?
An abrupt cessation in renal function which has got worse over a period of time.
List some causes of acute renal failure.
Leptospirosis infection
Poisoning
Hypovolaemia
CHF
Addisons
Obstruction
Reduction of blood flow to the kidneys.
What are the 3 different classes of acute kidney injury?
Pre-renal, renal, post-renal.
What are the signs of acute renal failure?
Lethargy
V+ D+
Halitosis
Anorexia
Dehydration
Oliguria/anuria
What is the treatment for acute renal failure?
IVFT
Treat underlying cause
Once hydrated, use diuretics to stimulate urine.
Diet - low protein/low phosphorus.
Peritoneal dialysis.
Monitor urine output.
Monitor vital signs.
What is peritoneal dialysis?
Used to filter waste products from the blood & reduce azotaemia.
Involves infusing sterile fluid into abdomen, to ‘soak up’ any nitrogenous waste in peritoneum. Fluid is then withdrawn.
What are some causes of chronic renal failure?
Nephrotoxins
Ischaemia
Pyelonephritis
Congenital/hereditary disease
Idiopathic
Dietary
Glomerulonephritis
What does Ischaemia mean?
Deficiency of blood in a part due to constriction/obstruction of the coronary arteries.
Signs of chronic renal failure?
Will vary depending on cause.
Dehydration
Vomiting
Anorexia
Halitosis
Swollen enlarged kidneys
Anuria
Polydipsia
What is the treatment for chronic renal failure?
Anti-emetics.
IV fluids
Vitamin B
Antibiotics
Anabolic steroids
Diet
What is nephrotic syndrome?
Usually an end stage disease progressed from glomerulonephritis. Large amounts of protein lost in the urine.
Symptoms of nephrotic syndrome?
Similar to chronic renal failure, as well as -
Hypoalbuminaemia
Subcutaneous oedema
Ascites
Severe proteinuria
What is cystitis?
Inflammation of the bladder.
What are the signs of cystitis?
Dysuria
Tenesmus
Pain
Haematuria
Increased frequency of urination (pollakiuria).
What does incontinence mean?
The inability to control urination.
What can incontinence be caused by?
Sphincter incompetence
Tumour
Prostatic disease
Neurological
Cystitis
Behavioural
What does management of incontinence involve?
Barrier creams to prevent scalding.
Frequent walks.
Good hygiene.
Indwelling catheter - recumbent/severe cases.
Drug therapy = propalin, urylin & incurin.
What is calculi?
Stones/crystals in the urinary tract.
