Abstract
Purpose of Review
The purpose of this review is to study the epidemiology, presentation, pathogenesis and management of ketamine cystitis and its complications.
Recent Findings
Recent data suggest that the toxicity of ketamine can be due to direct cytotoxicity, independent of a NMDA receptor-mediated mechanism. Bladder barrier dysfunction, neurogenic inflammation with abnormal neurotransmission and immunological mechanisms have also been proposed, based on data from animal models and in vitro studies. Effects on the bladder are dependent on the dose and duration of ketamine use. Clinical studies have showed that the model of outreach clinics with involvement of local urology services holds most promise, with a tiered approach to management based on stage of the disease.
Summary
Chronic ketamine use is associated with significant lower urinary tract symptoms including frequency, urgency, haematuria and bladder pain. This may progress to irreversible bladder dysfunction with poor capacity and compliance and upper tract dysfunction may also occur. The key to successful treatment is ketamine cessation. The role of medications is not well established but there may be benefit from drugs used for IC/BPS and bladder Botox. Patients with end stage disease will require surgery, but there is a high complication rate.
