Bladder changes after catheterizable channel creation in adults with cerebral palsy who are in chronic urinary retention.

CC creation facilitates CIC in adults with CP who are in chronic retention due to pseudodyssynergia. Despite preoperative UDS suggesting an adequate capacity, low-pressure bladder, such patients often manifest de novo NDO and worsening incontinence upon initiation of CIC after surgery. These findings should be considered when determining whether to perform augmentation at the time of CC in adults with CP.
