Objective:
Evaluation of bladder biofeedback in patients with sensory urgency refractory to medication and classical bladder training.
Methods:
In 12 such patients a non-electronic technique of bladder biofeedback was used. Ambulatory treatment sessions were done once a week for 4 weeks, as opposed to every 14 days, with a mean total treatment period of 8 weeks. Micturition charts were completed before, during and 14 days after treatment by the patient. Before starting, patients had a mean of 15.8 micturitions/day, 2.3 micturitions/night, and a mean functional bladder capacity of 96 ml (26-172 ml). Urodynamic investigation showed a low-capacity bladder, hypersensitivity in some patients, and normal urodynamic parameters in others.
Results:
At the end of biofeedback, patients had a mean of 5.7 micturitions/day, 0.3 micturitions/night, and a mean functional bladder capacity of 296 ml (163-470 ml). The results 9 months after completing the treatment were unchanged. Quality of life improved substantially in all.
Conclusions:
Bladder biofeedback is a valuable treatment for sensory urgency refractory to classical treatment.
