The role of uroflowmetry biofeedback and biofeedback training of the pelvic floor muscles in the treatment of recurrent urinary tract infections in women with dysfunctional voiding: a randomized controlled prospective study.

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.

Perineal ultrasound evaluation of dysfunctional voiding in women with recurrent urinary tract infections.

Purpose: We used urodynamics and perineal ultrasound to assess the function and morphology of the urethral sphincter and detrusor muscle in the evaluation of dysfunctional voiding in female patients with recurrent urinary tract infections.

Materials And Methods: Patients selected for study purposes completed the American Urological Association Symptom Index and underwent multichannel video urodynamics and perineal ultrasound to evaluate urethral sphincter volume and detrusor thickness.

Results: Of the 337 patients referred to our institution for recurrent urinary tract infections 166 were finally evaluated, including group 1-65 women with recurrent urinary tract infections and dysfunctional voiding, group 2-77 with recurrent urinary tract infections without dysfunctional voiding and group 3-24 healthy controls.
