Q
PR exam summary
A
lie left lateral. Check for blood, fistula, fissures, warts, piles, prolapse. Comment on tone, prostate, bowel, faeces. Ind – constipation, retention, masses
21
Q
hernia examination
A
examine standing up. Palpate scrotum, inguinal region, compress lump + cough, deep inguinal ring mid ASIS+tubercle -> reduce into deep ring ask to cough, see if reappears. Direct if so, if not indirect. Hand off – hernia projects straight forward if direct and slides obliquely if indirect. Percuss/ausc.
22
Q
inguinal hernia direct vs indirect
A
direct = superior to PT, herniates through superficial ring. Indirect = between deep ring + scrotum. Can be contained.
23
Q
femoral hernia o;e
A
always inferior and lateral to pubic tubercle. Less common
24
Q
testicular exmiantino
A
stand up, examine side on. Inspect all over. Palpate testes, epididymis, spermatic cord. If pain relieved by elevation – epididymitis, if not think of torsion. Absent cremasteric reflex in torsion usually. Check SCL nodes.
25

– fluid around testicles. Young – patent proceccus vaginalis. Old may be smaller and secondary to tumour/trauma/inf. US testicle and sac repair.
26
varicocoele
dilated venous plexus in scrotum ‘bag of worms’ feel. Dull ache. Left sided commoner. Can have surg to clip vein.
27
epididymal cyst
– separate, fluid-filled sac above epididymis
28

33
renal dialysis summary (indications, types, complications)
Renal dialysis – maintains electrolytes and removes plasma waste products. AKI indications = Acidosis Electro abnorm Intoxicants Overload Uraemia, CKD when eGFR <15ml/min. CKD = haemodialysis / peritoneal AKI = haemodialysis / haemo – filtration. Complications – headache, itch, muscle cramps, disequilibrium syndro (cerebral oedema from osmotic chng), low BP, haemolysis + hyperK, sepsis.
34
haemodialysis details (incl access)
AV fistula + either a tunnelled central venous catheter (stays for months) or non tunnelled (10 days)
blood taken from vein, pumped along semi permeable membrane, dialysate fluid pumped in oppo direction on other side. toxins diffuse out over gradient.
conventional - 4hrs, 3x weekly
short daily - 2 hrs /day
noctural - 6-8 hrs nightly 6 days a week
35
lifestyle modifications needed while on haemodialysis
fluid restrict, salt restrict, potassium restrict, phosphate restrict
36
peritoneal dialysis details
Peritoneal – Tenckhoff catheter. Continuous ambulatory (replace fluid bags 3-5 x daily or automated overnight over 8-10 hrs. peritoneum acts as the membrane.
37
haemofiltration why
used for more critically ill patients as less haemodynamic instability caused.
38
AV fistula o/e
o/e -> location, any inflamm, collapsing as should on arm elevation, any collateral veins, any oedema or ischaemia/Steal syndrome. Normal thrill and easy compression. Occlude vein above + see art pulsation- normal.
can be in wrist, ACF, upper arm basilic vein
39
venous stenosis of AV fistula
Venous stenosis – high pitched murmur, collateral veins, pulsatile vein w/out manoeuvre.
40
AV fistula info
AV fistula info – 6 weeks to dilate vein. Distal needle – afferent needle, proximal needle= efferent (both in AV fistula).
41
AV fistula cautions and complications
). Complications – thrombosis, v stenosis, aneurysm, infection, distal ischaemia (S syndro). Cautions – no bloods / cannula on AVF arm, no BP measure that side, keep clean, check daily
42
why have an AV fistula over a CVC?
Why AVF over CVC – lower re-circulation a/efferent mingling, less infection, higher flow rate – more efficient filtration, less clotting.
43
Tenckhoff catheter
catheter placed through abdo wall to access the peritoneum for dialysis.
always check for acute abdo / peritonism o/e.
either replace dialysate manually many times a day or auto repair auto replace overnight!
44
complications of peritoneal dialysis
peritonitis, infection, constipation, pleural effusion, hernias, weight gain
but at home and can travel
45
contraindications to peritoneal dialysis
adhesions (i.e. prev surgery), stoma, hernias, IBD
46
kidney failure o/e basic summ
o/e look for cause, evidence of dialysis + if active/historic, signs of Isupp
47
indications for renal transplant
Transplant ind – ESRF <15ml/min (diabetes, PKD, HTN, GN).
48
contraind to renal tansplant
Contraind – cardiac/lung failure, liver disease, cancer, active inflamm.
49
kidney transplant procedure
Procedure – pre op screen donor/recipient (HLA, x match, inf screen). Screen donor also with ultrasound, surgical bloods, urine tests. Donor kidney (loin scar) anastamosed with external iliac vein/artery
50
post op renal transplant
Post op Isupp = pred, tacrolimus, myco mofetil.
pred + calcineurin inhibitor + antimetabolie
51
complications kidney transplant
Complications – rejection (hyperacute – during op, acute – flu prodrome, reducing function + tenderness over many weeks, chronic – reducing func over years).
oppo infections, sepsis, EBV post tansplant lymphoprolif disorder, UTI, graft thrombosis
52
kidney T prognosis
. Lasts up to 15 years. Prognostic factors for kidney – donor type/age, cold time.
53
colostomy types
end or loop
end (either AP resection for low rectal tumours – permanent- or Hartmann’s procedure to resect rectosigmoid lesions + reverse once deflamed). Loop – loop of intact bowel brought out with 2 openings. Protects distal bowel i.e. if obstruction, palliative distal tumours, anastamosed lower down (reverse later).
54
ileostomy types
end or loop
end – subtotal or total colectomy +/- reversal with anoileal join up later. Loop – protects anastomosis lower down or protects anus e.g. IBD/ca.
55
urostomy
short piece of ileum removed + acts as bladder (after cystectomy).
56
stoma complications
– early (high output >1L/day dehydrates and loses K+, retraction, ileus, ischaemia), late (parastomal hernia, prolapse, fistulae, malnutrition
57
stoma care
) stoma care – stoma nurse expert, empty bag 2/3 full + irrigate / single-use bag, stays on in shower, first 2 months loads fluids/little fibre. Eat right to avoid block/diarr/odour
