Management of ketamine cystitis: National Guidelines from the French Association of Urology (CUROPF/CTMH).

The objective of the CUROPF and CTMH was to establish recommendations about ketamine induced uropathy management. A systematic review of the literature was conducted on Pubmed/Medline by the members of the French committees of female urology and male lower urinary tract symptoms focusing on the epidemiology, pathophysiology, diagnosis and treatment of ketamine induced uropathy, evaluating references and level of evidence. Recommendations include epidemiology, pathophysiology, diagnosis and treatment of ketamine induced uropathy. It represents a rising healthcare issue, with major augmentation of ketamine consumers and new patients across the world. Several pathophysiology pathways are suspected and need clinical validation. The diagnosis is clinical, with hyperactive bladder symptoms mostly including pollakiuria, but also lower urinary tract symptoms, and histological, requiring bladder biopsies to rule out carcinoma and show specific features and inflammation. Therapeutics are currently limited and non-specific, combining abstinence, hydrodistension, pentosane polysulfate and Botox injections. Complex reconstructive surgeries should be avoided and be considered as a last resort. These guidelines should provide tools to help every physician confronted to ketamine induced uropathy patients, which represents a growing issue. Hopefully, this work will allow the improvement of the screening, management and care of ketamine induced uropathy in the future.
