Ureterocystoplasty: a unique method for vesical augmentation in children.
Vesical augmentation may be accomplished by using small bowel, large bowel or stomach, and by detrusor myotomy or the autoaugmentation technique. The use of intestinal segments is associated with variable mucus production, electrolyte absorption and the risk of malignant transformation. Autoaugmentation is free of these potential risks but may be unsuccessful in creating sufficient improvement in vesical compliance and capacity. Ureterocystoplasty with a bladder based native ureteral flap has been used in neurovesical dysfunction in association with a nonfunctional refluxing kidney, in a noncompliant valve bladder associated with posterior urethral valves and a nonfunctional kidney, and in augmentation of a small bladder after closure of cloacal exstrophy. Adequate bladder capacity and compliance have been achieved without the use of extra urinary epithelium. The surgical approach is simple and uncomplicated. Ureterocystoplasty in selected cases will provide for adequate bladder capacity and compliance when augmentation cystoplasty is required.
