The management of patients with neurogenic bladder is complex. Several patients have been operated multiple times. Surgical procedures such as Mitrofanoff's, bladder neck surgery, bladder augmentation and urinary artificial sphincter, are common.~The investigators want to analyse the participants data, that led to indication of an urinary artificial sphincter, and its outcomes.
Retrospective monocentric study of the outcomes of patients with neurogenic bladder, who had a urinary artificial sphincter before the age of 18 years old.~Hypothesis: what was the impact of the urinary artificial sphincter on the global management of the patient.
