Renal

  • T.I.D (tubulointerstitial disease)
    • from nsaids, gentamycin, ace, ciclosporin
    • from ischaemia
  • from gn
  • also haemolytic uraemic syndrome

Post renal (us shows hydronephrosis)

  • stones
  • prostate
  • retroperitoneal fibrosis

—> Manage pulm oedema and hyperkalaemia

If pulm oed, hyperkal, acidosis, encephalop, pericarditis

Q

acute renal failure

prerenal (50%) vs atn (30%)

A

prerenal
- hypoperfusion (hypovol, sepsis)
- tubules still working so Na is resorbed
(low urine Na, high serum Na) and urine is concentrated (high osmol)

atn (tin)

  • ischaemia
  • nephrotoxins (nsaid, abx)
  • hepatorenal syndrome
  • GN, vasculitis, myeloma, HUS
  • –> high Na in urine and dilute

- aldost excess (cushings, conns)
(give diuretics)

normovol
- diabetes insipidus - fluid loss, dilute urine
(adh defic or nephrogenic - Ca, Li)

hypovol

  • burns, sweat, vom, diarr
  • diuretics
  • hyperglycaemia
80
Q

Hypercalcaemia >2.6

A

bones moans (depres) groans (constip) stones
peptic ulcers
—> nephrogenic diabetes insipidus

80% primary hyperparathyroidism
- PTH may be normal/rasied w Ca high
- polyuria, polydip, weakness, vom
- low phosphate
= adnoma or hyperplasia of gland
= can also be due to LITHIUM

20& malig
- consider if Ca high but PTH low
= myeloma of bone 2dry
= squam cell lc producing PTH-like protein

81
Q

diabetes insipidus - pissing too much fluid

A

inappropriately dilute urine, large vol

cranial = ADH deficiency

nephrogenic
= hypercalcaemia
= lithium

T: desmopressin (also used in von willebrands, haemophilia)

82
Q

Hypocalcaemia <2.1

A

tetany, seizures, qt elong

chvosteck (tap on facial nerve)

trousseau (bp cuff -> carpopedal spasm)

A

rare auto dom

  • intellect, epilepsy
  • facial angiofibroma

  • harmartoma
85
Q

VON HIPPEL LINDAU

A

autosomal dominant renal disorder

renal tumours
brain tumour - haemangioblastoma
adrenal tumou
- phaeo (htn, ha/sweat/tachy, trem,anxiety)

86
Q

bph

A

v common over 60
smooth enlarged prostate
psa normal <4 ideally
do msu to rule out UTI

complications

  • retention - may need self catheterisation
  • infection
  • stones

treatment

  • ? self catheterise
    1) alpha blocker - tamsulosin
    2) 5alpha red inh - finasteride (anti androgen - causes erectile/libido probs)
    2) surgery - resection or stenting/dilate
87
Q

hyperprolactinaemia

A

galactorrhoea
bitemporal hemianopia
w: menstual prob, infertility
m: erectile dys

C: prolactinoma
- also stress, renal fail, PCOS

T of prolactinoma

1) dopamine agonists (shrink)
2) surgery and radio

88
Q

prostatism history

A

voiding probs
- hesitancy/strian, poor flow, terminal dribble, pis en deux

storage probs
- urgency, frequency, nocturia, incontinence

any red flags - weight loss, bone pain, blood in urine

family history
medications

cause

  • bph
  • prostate cancer
89
Q

bph

A

v common over 60
smooth enlarged prostate
psa normal <4 ideally

complications

  • retention - may need self catheterisation
  • infection
  • stones
treatment
1) alpha blocker - tamsulosin
2) 5alpha red inh - finasteride (anti androgen - causes erectile/libido probs)
Catheteristion
Surgery - turp
90
Q

prostate cancer

A

psa raised - over 10 is suspicious

  • do TR US
  • do TR punch biopsies

gives gleason score “3+4” means mainly stage 3 some 4 (5 is worst)

also use tnm staging - do ct

do cxr, bonescan and renal us to look for mets

treatment

  • wait
  • surgery - turp of total prostatectomy
  • radio - external beam or brachytherapy
  • gnrh analogue - goserelin - “zolidex 3m injections”
  • newer anti androgen drugs
