Ketamine and bladder dysfunction

Findings are show a link between the recreational use of ketamine 3 or more times a week and bladder problems that can linger more than a year after its use.


Associated bladder dysfunction includes:

  • urinary frequency
  • urinary urgency
  • epigastric pain

The recreational use of ketamine reduces bladder capacity to about 200 mls.

Normal bladder capacity is 400-500ml

The bladder capacity has been shown to recover gradually after a year of abstaining from ketamine abuse.


In extreme cases of chronic ketamine abuse bladder fibrosis has been shown to set in, reducing bladder capacity to less than 50mls with little recovery when ketamine use stops.

Treatment and Management:

  1. Stopping ketamine use
  2. Bladder reconstructive surgery
