The criteria for evaluation of urinary diversion procedures in childre
n must be strict since their life expectancy is long, Our experience w
ith the modified rectal bladder in children with considerable follow-u
p periods is reported herein. All patients were continent by day and n
ight. Urography studies revealed a normal upper tract in all cases. Th
ree early complications were encountered among patients who had a subm
ucous tunnel reimplantation. Reflux to the proximal colon or the kidne
ys 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 co
nclude that a modified rectal bladder with a second ileal intussuscept
ion valve is the operation of choice whenever urinary diversion in chi
ldren is indicated.
