Investigations
Bedside: urine dip for haematuria

Imaging
1. CT Urogram - identifies filling defects
2. Flexible cystoscopy - rigid cystoscopy can take biopsy
Mx: non-muscle invasive (CIS, Ta and T1)
- Surgery = Transurethral resection of the bladder tumour (TURBT)
- Chemotherapy (Mitomycin C) at TURBT or at weekly intervals following a TURBT.
Mx: muscle invasive (T2 and above)
If no significant comorbidities and/or metastasis – cystectomy with urinary diversion
Options for urinary diversion
Ileal conduit
Neo-bladder
Mx: non-surgical of muscle invasive
Radiotherapy:
Chemotherapy:
