The modified rectal bladder in children: long-term follow-up.

The criteria for evaluation of urinary diversion procedures in children must be strict since their life expectancy is long. Our experience with the modified rectal bladder in children with considerable follow-up periods is reported herein. All patients were continent by day and night. Urography studies revealed a normal upper tract in all cases. Three early complications were encountered among patients who had a submucous tunnel reimplantation. Reflux to the proximal colon or the kidneys was not demonstrated. The metabolic status and growth-rate patterns of these patients were within normal limits without alkaline therapy. All urine samples aspirated from the renal pelves were sterile. We conclude that a modified rectal bladder with a second ileal intussusception valve is the operation of choice whenever urinary diversion in children is indicated.
