Condition
Idiopathic detrusor overactivity
Intervention
Patients will be randomised to receive intradetrusor injections of 500u Botulinum Toxin-A (Dysport) sparing the trigone or including the trigone. 500u Dysport will be reconstituted with 20ml 0.9% saline. For trigone-sparing patients, 1 ml will be injected into 20 sites around the bladder sparing the trigone. For trigone-including patients, five 1 ml injections will be administered into the trigone and 15 injections around the bladder outside the trigone.
