Biofeedback in the treatment of detrusor instability.

Detrusor instability has remained resistant to conventional forms of treatment. An attempt to use biofeedback methods in its management is described. Six female patients with symptoms of frequency, urgency and urge incontinence due to detrusor instability were conditioned to auditory and visual stimuli for 6 to 8 1 h sessions. They were assessed clinically and urodynamically. The results are presented as well as detailed case studies of 3 patients. Subjectively, 3 were cured, 2 improved and 1 remained the same; objectively, 3 were cured, 1 improved and 2 remained the same. No significant side effects were encountered.
