Objectives: To evaluate the efficacy of a training program with uroflowmetry biofeedback and pelvic floor relaxation biofeedback on urodynamic and voiding parameters in women with dysfunctional voiding.
Methods: Eighty-six women with recurrent urinary tract infections (UTIs) and dysfunctional voiding were randomly assigned to receive a treatment schedule as follows: uroflowmetry biofeedback (group 1), biofeedback training of the pelvic floor muscles (group 2), uroflowmetry biofeedback combined to biofeedback training of the pelvic floor muscles (group 3), no treatment (group 4). Patients were regularly evaluated by American Urological Association Symptom Index and urodynamics during the study period. All the patients were followed up for 1 year with monthly urine cultures. A further evaluation was done at month 24 by American Urological Association Symptom Index and free uroflowmetry with measurement of residual urine.
Results: The prevalence of storage and emptying symptoms decreased significantly at 3, 6, and 12 months in the groups 1, 2, and 3, and remained stable during the study period. Mean flow rate, flow time, voiding volume increased significantly, whereas postvoid residual urine decreased. The prevalence of UTI decreased significantly in groups 1, 2, and 3. At month 24, storage and emptying symptoms and voiding patterns were similar to the baseline values in all the patients. The incidence of UTIs was similar to baseline values in groups 1, 2, and 3.
Conclusions: Training the voluntary control of the pelvic floor seems essential in obtaining control over the bladder function. These results reinforce the importance of pelvic floor therapy in the resolution of UTIs.
