Perineal ultrasound evaluation of dysfunctional voiding in women with recurrent urinary tract infections
Abstract
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. 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. 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. Storage and emptying symptoms were recorded in 87.6% and 84.6% of group 1 patients, respectively. Opening and maximum flow detrusor pressure significantly correlated with urethral sphincter volume, and mean and maximum urethral closure pressure and detrusor thickness correlated with urethral sphincter volume. Dysfunctional voiding could be diagnosed by ultrasound when an increase in detrusor thickness and striated sphincter volume were observed. A threshold sph...Continue Reading
