Introduction: We aimed to summarize current literature about radiation cystitis treatments, providing physician of a summary of current management options. Evidence acquisition: A systematic literature review searching on PubMed (Medline), Scopus, and Web of Science databases was performed in March 2021. PRISMA guidelines were followed. Population consisted of patients with a diagnosis of radiation cystitis after pelvic radiotherapy (P). We focused our attention on different treatments, such as conservative or surgical one (I). Single or multiple arms studies were deemed eligible with no mandatory comparison (C). Main outcomes of interest were symptoms control and adverse events rates (O). Evidence synthesis: The search identified 1,194 records. Of all, four studies focused on the use of hyperbaric oxygen therapy showing complete response rates ranging from 52 to 87% approximately. Oral administration of cranberry compounds was investigated in one study showing no superiority to placebo. Intravesical instillation of different compounds were investigated in five studies showing the highest complete response rates after alum (60%) and formalin administration (75%). Endoscopic conservative surgical treatments (fibrin glue or vaporization) also showed 75% complete response rates. In patients who did not respond to conservative treatments robotic cystectomy is feasible with overall complication rates of about 59.3% at 90 days. Conclusions: Radiotherapy induced cystitis is an under-reported condition after pelvic radiotherapy. Several treatments have been proposed, but in up to 10% of cases salvage cystectomy is necessary. A stepwise approach, with progressive treatment aggressiveness is recommended.

Abstract

Introduction: We aimed to summarize current literature about radiation cystitis treatments, providing physician of a summary of current management options. Evidence acquisition: A systematic literature review searching on PubMed (Medline), Scopus, and Web of Science databases was performed in March 2021. PRISMA guidelines were followed. Population consisted of patients with a diagnosis of radiation cystitis after pelvic radiotherapy (P). We focused our attention on different treatments, such as conservative or surgical one (I). Single or multiple arms studies were deemed eligible with no mandatory comparison (C). Main outcomes of interest were symptoms control and adverse events rates (O). Evidence synthesis: The search identified 1,194 records. Of all, four studies focused on the use of hyperbaric oxygen therapy showing complete response rates ranging from 52 to 87% approximately. Oral administration of cranberry compounds was investigated in one study showing no superiority to placebo. Intravesical instillation of different compounds were investigated in five studies showing the highest complete response rates after alum (60%) and formalin administration (75%). Endoscopic conservative surgical treatments (fibrin glue or vaporization) also showed 75% complete response rates. In patients who did not respond to conservative treatments robotic cystectomy is feasible with overall complication rates of about 59.3% at 90 days. Conclusions: Radiotherapy induced cystitis is an under-reported condition after pelvic radiotherapy. Several treatments have been proposed, but in up to 10% of cases salvage cystectomy is necessary. A stepwise approach, with progressive treatment aggressiveness is recommended.
