ABSTRACT
The primary aim is to ensure adequate drainage of the urinary tract and thereby preserve renal function. This chapter will not focus on the routine procedures requiring urinary diversion such as urethral/suprapubic bladder drainage or nephrostomy but will primarily cover longer-term or permanent urinary diversion. A continent diversion aims to create a low-pressure, compliant, and capacious reservoir and a catheterizable conduit for drainage of the reservoir where the urethra is found to be unsuitable. The assessment and preparation of children for surgery for urinary diversion consist of three components: Overall assessment, Renal assessment and Assessment for the specific procedure. The principles of the technique are similar to those described for ileocystoplasty, as are the postoperative care and complications. In 1911, Coffey described the flap valve technique of ureteral reimplantation in ureterosigmoidostomy. A broad-based rectangular flap of full-thickness detrusor muscle and mucosa is raised on its vascular supply from the superior vesical pedicle.
