Table 4
The proposed intravesical treatments for radiation cystitis and their levels of evidence.
| Intravesical agent | Level of evidence | Data |
| Botulinum toxin A | 4 | Increase in bladder capacity | Reduction in urinary frequency from 14 to 11 episodes | No side effects reported [19] |
| Hyaluronic acid | 1b | Significant reduction in voiding frequency | Significant reduction in pelvic pain | Reduction of haematuria equal to that of hyperbaric oxygen | Side effects: increased rate of UTIs at 6 months [20] |
| Chondroitin sulfate | 2b | Reduction in self-reported bladder symptoms | No side effects reported [21] |
| Formalin | 4 | Significant reduction in haematuria | High complication rate including mortality [22ā24] |
| Polydeoxyribonucleotides | 3 | Improvement in reported cystitis symptoms [25] |
| Early placental extract | 3B | Symptomatic improvement in radiation cystitis | Cystoscopic improvement in radiation cystitis [26] |
