Ketamine-induced cystitis resulting from long-term abuse: A case report
Main Article Content
Abstract
Ketamine-induced cystitis (KIC) is a severe urological condition resulting from ketamine abuse, characterized by persistent lower urinary tract symptoms (LUTS), often misdiagnosed, and associated with irreversible bladder damage risk. We report a case of a 26-year-old woman with a 4-year history of ketamine abuse who presented with a 2-year history of complex LUTS, including urinary frequency (every 5 - 10 minutes), urgency, and suprapubic pain. She had no sign of tuberculosis, negative urine cultures, and no response to antibiotics. Computed tomography (CT) of the urinary tract revealed a small, diffusely thickened bladder wall (8mm) without obstruction. The patient was diagnosed with KIC and managed conservatively with ketamine cessation, pharmacologic therapy (neuropathic pain control and anticholinergics), and pelvic floor rehabilitation. After 10 days, her symptoms markedly improved, with voiding intervals increasing to 60 - 120 minutes and no withdrawal symptom observed. She was discharged and followed up as an outpatient. KIC should be considered in young patients with persistent LUTS; eliciting a history of substance abuse is essential for diagnosis, and cessation of ketamine use remains the cornerstone of treatment.
