Q

What is the difference between a directed and undirected altruistic donor?

A

Directed - family member or friend is motivated to donate after someone they know becomes ill

Undirected - anyone off the street comes in to say they wish to donate their kidney

Q

Receiving dialysis before a kidney transplant is better than if no dialysis is used. TRUE/FALSE?

A

FALSE

dialysis has many risks (e.g. CVD) => it is better to not require it at all before a transplant

Q

What factors of a kidney donation surgery should you ensure the receiver is able to tolerate?

A
  • General Anaesthetic

Q

What are the various parts of the recipient assessment?

A
Immunology – tissue typing etc
Virology (to exclude active infection)
Assess:
- Cardiorespiratory risk
- peripheral vessels
- bladder function
- mental state
- co-morbidity/PMHx which may influence transplant OR be exacerbated by immunosuppression

Q

Where is the transplanted kidney placed in the body?

A
  • iliac fossa
  • Attached to external iliac artery and vein
  • Ureter plumbed into bladder with stent
17
Q

What are the main surgical complications of a kidney transplant?

A
Bleeding
Arterial/Venous stenosis OR kinking
Ureteric stricture => hydronephrosis
Wound infection
Lymphocele
18
Q

What is meant by delayed graft function?

A
  • Post-transplant Acute Tubular Necrosis (kidney asleep)
  • Often need Haemodialysis in interim
  • Usually works within 10-30 days
19
Q

What is meant by Primary Non-function?

A

Transplant never works/ wakes up

20
Q

What are the different types of rejection?

A

Hyperacute rejection

  • preformed antibody reaction
  • Unsalvageable
  • Transplant nephrectomy required

Acute Rejection

  • Cell/Antibody mediated
  • Tx with increased immunosupression

Chronic Rejection

  • Antibody mediated
  • slow decline in renal function
21
Q

What induction treatments are used for immunosuppression during kidney transplants?

A

Basiliximab/Dacluzimab

22
Q

What steroid is given IV during a transplant operation?

A

Prenisolone

23
Q

What agents are used for maintenance immunosuppression after a kidney transplant?

A

Prednisolone, tacrolimus, MMF
Prednisolone, ciclosporin, azathioprine

covers all bases in the immune system

24
Q

What treatments are specifically to prevent rejection of kidney transplants?

A

IV methylprednisolone
Immunoglobulins
Plasma
Monoclonal Antibodies

25
Q

What infections can kidney transplant patients develop due to the immunosuppression?

A

Bacterial infection:
UTI (especially females)
Give prophylaxis for Pneumocystis Jirovecci Pneumo.

Viral infections:
CMV, HSV, BK

Fungal infections:
e.g. candida

26
Q

Kidney transplants can predispose to what types of skin cancer?

A

non-melanoma

=> BCC/SCC

27
Q

What infection can cause Post transplant Lymphoproliferative Disease?

A

EBV

depending on level of immunosuppression

28
Q

What treatment is given for Post transplant Lymphoproliferative disease?

A

NO ANTIVIRALS

  • Reduce immunosupression
  • Chemotherapy
