Alder Hey Children's Hospital has opened the UK's first clinic for young people suffering from severe bladder damage linked to ketamine addiction.

Alder Hey Children's Hospital in Liverpool has established the UK's first specialist clinic for young people suffering from 'ketamine bladder,' a severe urological condition caused by the drug. Analysis of the clinic's first 60 patients reveals that some children are as young as 13, with an average age of 14. The clinic, which opened in May 2025, reports a rapid escalation in referrals for symptoms including incontinence, chronic pain, and blood in the urine.

Nature of the Condition

Ketamine-induced uropathy, or 'ketamine bladder,' occurs when the drug and its breakdown products damage the bladder lining and muscle tissue. Experts note that the condition can cause ulceration, fibrosis, and damage to the kidneys and ureters. Symptoms are frequently described as painful, with patients reporting a sensation of 'weeing over broken glass,' frequent urges to urinate, and a loss of bladder control. In severe cases, the damage is irreversible, potentially requiring major surgery, bladder removal, or dialysis.

Patient Demographics and Drivers

The clinic's analysis indicates that most patients are girls living in deprived areas. Many children seen at the facility have pre-existing conditions such as ADHD or have been involved in the care system. Doctors report that some patients enter a 'K loop,' where they use ketamine to numb the very pain the drug has caused in their bladder. Factors contributing to the rise in use include the drug's low cost and its prevalence in school environments, making it difficult for some users to quit.
