Artificial urinary sphincter insertion in congenital neuropathic bladder. A series of 44 patients with neuropathic bladder dysfunction due to congenital myelodysplasia underwent implantation of an artificial urinary sphincter (AUS); in 26 patients a reconstructive procedure was performed at the same time. Five patients who initially had AUS implantation alone developed detrusor hyper-reflexia and required a clam cystoplasty. Forty patients (90%) are continent, 2 are occasionally damp and 2 are wet and awaiting further surgery; 66% of patients who underwent AUS insertion and reconstruction were found to have significant residual urine and they perform intermittent self-catheterisation (ISC). In patients with a good bladder capacity and normal compliance and detrusor hyper-reflexia controlled by anticholinergic drugs, cystoplasty is not necessary at the time of AUS insertion.
