Renal medicine and urology Hx's Flashcards
What are the are 2 types of presenting complaints of haematuria?
- frank haematuria
- more likely due to a lower UTI lesion
- 20-25% malignancy risk so more aggressively investigated than below
- microscopic haematuria
- suggestive of glomerular disease
- relatively more common
- only pathological when recurring or associated with lower UTI symptoms
What should be covered in HPC of haematuria?
CLOTS
CL- Clarify, when do you notice blood? passing urine? could it be from somewhere else? eaten beetroot?
O - onset, first noticed bloos?
T- timing, always blood in urine or does it come and go? had this before? blood present at start/end or throughout urination?
S- severity, do you pass any clots? [NB: presence of clots makes a glomerular cause more likely]
What are the associated symptoms with haematuria?
- pain (tummy, urethra, back - SOCRATES)
- Frequency (urges/incontinence)
- Nocturia
- urinary stream (diff getting started, dribbling, powerful/weak stream)
- poor urinary stream ~obstructive cause
- constitutional (- unwell/feve/chills/appetite/weight loss)
- Renal failure - recent weight gain, swollen ankles
- gloperulonephritidies (acute/chron inflam of renal glomeruli capillaries) - sore throats/rashes or sore joints?
- pulmonary-renal conditions ( oft. autoimmune)? - coughing blood
- trauma to stomach or groin?
What conditions should be specifically mentioned in a haemaaturia PMH and FH?
- PMHx: previous UTIs
- prostate/renal bladder cancer
- BPH
- diabetes
- hypertension
- FAMILY Hx: renal disease inc polycystic kidneys
- bleeding disorders
- asymptomatic haematuria run in family (fam members also have blood in urine )
What are the renal malignancies as DDx for haematuria?
- Renal cell carcinoma
- Renal cell carcinoma (RCC) is a kidney cancerthat originates in the lining of the proximal convoluted tubule, a part of the very small tubes in the kidneythat transport primary urine.
- transitional cell carcinoma
- Transitional cell carcinomas don’t start in the kidney itself, but in the lining of the renal pelvis (where the ureters meet the kidneys)
What are the signs/symptoms of renal cell carcinoma?
- Triad: Flank pain, haematuria and an abdominal mass late presentation)
- Commonly found incidentally in pts with HTN or Anaemia
- constitutional Sx: weight loss, fever, fatigue
- may present w/paraneoplastic syndrome causing excessive renin, PTH or EPO
What are the signs/symptoms of transitional cell carcinoma?
- Worrying = Painless, intermittend haematuria + in older MALES
- most common affected is bladder but can affect ureters or urethra too
- assoc w/ industrial dyes
- but BIGGEST risk = smoking now in UK
- Schistosomiasis is biggest bladder cancer cause elswhere e.g. africa (microscopic adult worms)
What are the S/Sx of renal calculi?
- Classical presentation = acute onset of excruciating flank/abdo pain; loin to groin radiation w/ N&V
- renal colic pain is more constant than biliary/intestinal colic but often has periods of relief where dull ache only
- often is asymptomatic and found incidentally
- typically affects men in 30s-50s
What are the S/Sx of UTI?
- cystitis triad: Urinary freq, urgency and dysuria
- fever, suprapubic pain and urethral discharge may also be present
- urine maybe cloudy with a foul odour and may contain blood
- more common in women, elderly
- only symptom maybe delirium
What are the S/Sx of glomerulonephritis?
- can cause nephritis with frank haematuria or nephrotic syndroms
- many different causes:
- associated preceding URTI (post streptococcal or IgA nephropathy)
- haemoptysis (goodpastures syndrome)
- systemic features e.g. rash (vasculitis)
What are the other DDx for haematuria?
- [as well as UTI, renal calculi, glomerulonephritis, renal cell/transitional cell carcinoma]
- urinary tract injury
- blunt, penetrating or iatrogenic (catheterisation)
- coagulopathy e.g. haemophilia
- prostatitis
- BPH and prostatic carcinoma (though haematuria not typically seen)
- beetroot (turns urine pink)
- [NB: pts may not think pink urine is blood so be sure to ask urine colour if blood is denied]
What investigations can be done for haematuria?
- UTIs = urinalysis, MC & S for UTI
- U&Es, FBC and clotting
- eGFR
- Autoantibody screen - ANCA (granulomatosis), ANA (SLE) and anti-glomerular basement membrane (attacks lungs too)
- bladder cancer = urine cytology and cytoscopy
- Masses = USS renal tract
- IV urography or CT scan if still no cause found
- glomerulonephritis confirm via renal biopsy
What is the management of haematuria?
- frank haematuria –> urgent referral to urology or nephrology
- bladder cancer –> transurethral resection for superficial tumours; radical cystectomy and urinary diversion for invasive disease; possibly chemotherapy
- renal cell carcinoma - nephrectomy
- renal calculi - <5mm usually pass on own;
- extra corporeal lithotripsy or endoscopic stone removal for medium size stones;
- for larger stone removal = intracorporeal or open operations
- UTI - antibiotics e.g. trimethoprim in simple uncomplicated cystitis
- Nephrotic syndrome - treat cause; furosemide, ace inhibitors and Ca channel blockers to control fluid retention and HTN
- Rapidly progressive glomerulonephritis requires prompt treatment with high dose steroids and cyclophosphamide
