Virtual trainer for intra-detrusor injection of botulinum toxin to treat urinary incontinence.

Here we introduce a new virtual reality (VR) based simulation system for training the urological procedure of intra-detrusor botulinum toxin (Botox®) injections into the bladder. 6 cases with different bladder anatomy and 3 subtasks are included in the curriculum; this design is guided by several expert urologists according to clinical needs and experience. These virtual bladder models can be deformed by a cystoscope model or penetrated by a needle model.
