OBJECTIVES In this preliminary study we report the development of the video urodynamic technique using magnetic resonance imaging (MRI). MATERIALS AND METHODS We studied 6 women with genuine stress urinary incontinence, diagnosed by history and physical examination. Urodynamic examination was performed on multichannel equipment with the patient in the supine position. Coughing and Valsalva ma...

All cases of stress urinary incontinence (SUI) are not the same; urethral pressures, prolapse conditions, and congenital and acquired sphincteric dysfunction all contribute to SUI pathophysiology. In order to optimally manage SUI, a thorough understanding of the pathophysiology behind the condition is necessary. Unsuccessful treatment of incontinence can result from the procedure itself or from...

PURPOSE To analyze the influence of urethral mobility and Valsalva leak point pressure on postoperative outcomes of transobturator sling (TOT) for female stress urinary incontinence. MATERIALS AND METHODS A prospective cohort was conducted including 66 patients submitted to TOT from March 2006 to May 2009. Urethral hypermobility was defined as mobility ≥ 30° on Q-tip test, and Valsalva leak p...

PURPOSE The purpose of this study is to determine the predictive factors that are associated with stress urinary incontinence (SUI) due to intrinsic sphincter deficiency (ISD) in women. METHODS Between January 2008 and December 2009, 185 women with urodynamically proven SUI were included in this study and retrospectively reviewed the medical record. Preoperative SUI symptoms were classified b...

We describe a unique physical diagnostic sign that we have observed in seven patients with bronchopleurocutaneous fistulas. Such patients have a highpitched squeak over the affected chest area during sustained Valsalva maneuver. We postulate that turbulence across the bronchial fistula due to high transbronchial pressure gradient during the Valsalva maneuver produces the squeaking sound. The pi...

Bronchial fistulae in communication with atmospheric pressure can be identified by the presence of a squeaking sound heard over the chest wall during a Valsalva maneuver. Furthermore, these leak sounds can help identify the size, location, and communications of the bronchial fistulae. The size of the leak can be inferred by the pitch of the leak sound. Large leaks produce low pitched sounds, sm...
