Other Inflammatory Bladder Diseases: Eosinophilic and Ketamine-induced Cystitis, Follicular Cystitis, Cystitis Cystica and Glandular Cystitis, Virus-induced Cystitis and Radiation Cystitis

Purpose: To provide an overview on Eosinophilic, Ketamine-induced cystitis (KIC), Follicular cystitis, Cystitis cystica, Glandular cystitis, Virus-induced cystitis (VIC) and Radiation cystitis (RC), and to present the most recent insights. Recent Findings: France and UK developed a KIC guideline, the Italian pediatric hematology oncology society a VIC guideline and a Dutch-German group a RC guideline. The impact of these guidelines on management outcomes has yet to be assessed. Furthermore, viral-specific T-cells to treat BK-VIC showed promise in a meta-analysis. Finally, long-term outcomes of a randomized-controlled trial on hyperbaric oxygen for RC demonstrated its potential for recurrence prevention. Knowledge on other inflammatory bladder diseases has slowed down over most recent years. Summary: Literature in recent years has focused on clinical guideline development, meta-analyses and long-term outcomes of trials for KIC, VIC and RC. Research on novel approaches and on other inflammatory bladder diseases was limited and needs renewed attention.
