Neurogenic urinary retention in cats following severe cluster seizures.

Case series summary Four cats that presented with severe cluster seizures developed neurogenic urinary retention in the postictal phase. None of the cats had previous seizures. Micturition was reported as normal in all cats for 3 or more years before seizure onset. All cats required a continuous rate infusion of propofol to control the seizure activity. In all cats manual bladder expression was performed every 8 h until recovery of normal micturition. One cat was started on phenoxybenzamine to reduce internal urethral sphincter tone. All cats recovered normal micturition within 4 weeks of the last cluster of seizures. Relevance and novel information Transient neurogenic urinary retention has not previously been reported in cats or dogs following severe cluster seizures. Urinary retention should be considered a potential postictal deficit, requiring prompt recognition and treatment to avoid urinary tract infection and detrusor muscle atony.
