The purpose of this study is to evaluate the effectiveness and safety of a minimally invasive surgical procedure with ACT (Adjustable Continence Therapy) balloons implantation for the treatment of urinary incontinence in children with bladder exstrophy or isolated epispadias.
The ACT therapy consists of two small adjustable silicone balloons connected with a tubing to a port, surgically placed around the bladder neck, one on each side of the urethra.
Boys and girls > 5 years with bladder exstrophy or isolated epispadias;
sphincteric incontinence (leak point pressure < 45 cm d'H20, open bladder neck during filling, stress urinary incontinence);
normal renal function (eGFR > 90ml/min);
no (or stable) upper urinary tract dilatation in ultrasound.
under 5 years or more than 18 years old;
renal insufficiency (acute or chronic);
evolutive deterioration of the upper urinary tract (hydronephrosis);
unmanageable detrusor instability;
