The current LUTD Program at the investigator's institution includes a full history and physical exam followed by extensive education. If the patients do not improve they undergo additional evaluation with a renal pelvic ultrasound and simultaneous uroflowmetry and electromyography (EMG) study. Based on that evaluation a percentage of patients go on to receive biofeedback treatment. Biofeedback is typically recommended to patients who do not use the pelvic floor and abdominal muscles appropriately while voiding. The biofeedback treatment involves further education, standard biofeedback, and biofeedback computer games. In standard biofeedback, patients are made aware of their abdominal and pelvic floor muscle activity by a display that shows the abdominal and pelvic floor muscles' EMG activity. In the biofeedback computer games, patients control a variety of games with their pelvic floor and abdominal muscles. Both methods teach the patient how to locate the pelvic floor muscles and to isolate them while voiding. Biofeedback represents only one possible treatment plan for children with LUTD. Patients are analyzed prior to entering the biofeedback portion of the LUTD Program for compatibility with this treatment.
