Bladder evaluation in pediatric patients before undiversion in previously diverted urinary tracts.

An easily performed test is described for simulating physiologic micturition in the defunctionalized bladder. Accurate clinical observations of continence and emptying capabilities before undiversion or transplantation are therefore possible. The test has predicted accurately adequate functional capabilities of the bladder in a series of children after total reconstruction. Moreover, when abnormal bladder function is identified by this technique a more physiologic state is provided for further investigation by more sophisticated urodynamic techniques. Successful retesting after appropriate corrective measures have been taken will avoid complications in the undiverted patient.
