2. Types

   • Benign
     • Papilloma
       • Leiomyoma
   • Malignant
     • TCC
       • SCC
         • Adenocarcinoma
           • Rhabdomyosarcoma

3. Signs and symptoms

   • Frequency
     • Painless hematuria
       • Dysuria

4. Risk factors

   • Smoking
     • Azo dyes
       • History of bladder infections
         • Catheters
           • Family history of bladder cancer
   • Schistosomiasis
     • parasite infection by Schistosoma mansoni, S. japonicum, S. mekongi, S. intercalatum and S. haematobium.
     • Transmission
       • fresh water containing larval forms (cercariae) of schistosomes, which develop in snails. Larvae penetrate the skin of individuals swimming or wading in water. Snails become infected as a result of excretion of eggs in human urine or faeces.
     • Symptoms
       • mansoni,, mekongi and japonicum causing hepatic and intestinal signs
       • Haematobium causing urinary dysfunction.

5. Investigations

   • Cytoscopy
   • Imaging
     • KUB X-ray
     • IVP
     • Retrograde pylogram
   • Urine cytology
   • Biopsy
   • Urinalysis
   • Culture sensitivity test
