Plain-English summary
An 18-year-old male domestic shorthair cat was brought in because he was lethargic and had blood in his urine. He had a previous spinal injury that caused incontinence and was found to be dehydrated and cold. An ultrasound showed a thickened bladder wall, and after supportive care, he initially improved but returned 10 days later with the same symptoms. Tests revealed a urinary tract infection caused by a rare bacteria, Corynebacterium urealyticum, leading to a condition called encrusting cystitis. The cat received treatment and was discharged again, but the case highlights the importance of considering this uncommon infection in older cats with certain health issues.

Abstract
An 18-year-old male neutered domestic shorthair cat was presented for investigation of haematuria and lethargy. The cat had sustained a traumatic T3-L3 lesion 5 years prior resulting in upper motor neuron incontinence. On further investigation the cat was found to be hyperkalaemic, hypothermic and dehydrated. Ultrasonography of the bladder revealed a markedly hypoechoic, thickened bladder wall with an irregular, hyperechoic mucosal layer. The patient responded to symptomatic and supportive care and was discharged. Despite initial improvement, the patient returned 10 days after discharge with recurrence of haematuria and lethargy. Ultrasound-guided aspiration and culture of the material on the mucosal surface of the bladder confirmed diagnosis of UTI caused by Corynebacterium urealyticum. On post-mortem examination, gross and histopathological features were consistent with encrusting cystitis. This is the first case report of encrusting cystitis in a cat. C urealyticum, an uncommon urinary tract pathogen in small animals, should be considered in patients with predisposing conditions.
