## Macroscopic haematuria
**DDx**
- trauma — eg catheterisation
- always needs Ix in NON-catherised pt
- infection — haemorrhagic cystitis
- Tumour
- 13% of cases if no other cause found
- ureteric or [[Renal colic|renal calculi]]
- polycystic kidney disease
- Glomerular disease
- Look for proteinuria , renal impairment, leuks
- Idiopathic
**Hx**
- pattern —
- Initial and terminal haematuria suggests lower urinary source
- Through all urination suggests upper tract
- Pain
- Painless suggests malignancy
- Bladder volume
- heavy haematuria can cause clot retention → inadequate bladder emptying
**Ix**
- usually CT abdo initially
- Will often need cystoscopy
> [!doses] Painless Haematuria DDx
> - urological malignancy
> - infection -- UTI, pyelonephritis
> - vascular -- AV fistulae, AAA
> - renal -- glomerulonephritis
> - coagulopathy -- over anticoagulation, haemophilia
> - iatrogenic/traumatic -- post catheter, radiation, biopsy, post-stent
## Bladder washout for clot retention
insert the largest 3 way Foley IDC possible
- usually 22F
- 18-20F sizes can be used if needed
- smaller sizes are more prone to obstruction
- manually aspirate clot with a Toomey syringe until clear of clots
- commence a bladder washout until haematuria light in colour
- monitor input and output volumes closely
- output < input indicates obstruction and will require manual aspiration to resolve
- admission will be required unless haematuria rapidly clears
- treat the underlying cause
