The aims of the present study were to evaluate test-retest intra-observer repeatability of ultrasound measurement of the morphology and function of the pelvic floor muscles (PFM).Seventeen subjects were tested twice. Two-, three-and four-dimensional ultrasound recorded cough, huff, muscle morphology and PFM contraction, respectively. Analyses were conducted Perineal ultrasound is a reliable method for measuring most of the tested parameters regarding morphology and function of the pelvic floor muscles.

“…During the examination, we were able to evaluate the mobility of the proximal urethra, urethral angle, funneling of the bladder neck, and voluntary contraction of the pelvic floor, following standardized criteria under three conditions: at rest, during contraction and during a Valsalva maneuver (8,9,13,17).…”

“…We calculated the anterior and the posterior bladder neck mobility under conditions of rest, pelvic floor contraction and Valsalva maneuver. The movement of the bladder neck was calculated by the following formula: √(x2-x1)²+(y1-y2)², where x1 and y1 represent the rest coordinates (8,9,(16)(17)(18)(19) (Figure 2).…”

Parameters of two-dimensional perineal ultrasonography for evaluation of urinary incontinence after Radical Prostatectomy

et al. 2014

ARTICLE INfO ______________________________________________________________ ______________________Introduction: Urinary incontinence remains a major concern for patients undergoing radical prostatectomy. Its prevalence can reach 20% in the late postoperative period. Materials and Methods:This clinical study investigated the differences of a dynamic evaluation of the urethra and pelvic floor contraction using perineal ultrasound in men without prostate surgery and in men submitted to radical prostatectomy with and without stress urinary incontinence. Ninety two male patients were included, which 70% of them underwent radical prostatectomy (RP) for more than one year. Thirty one men with clinically post prostatectomy incontinence were compared by two-dimensional (2D) perineal ultrasound to 34 patients without post prostatectomy incontinence and to 27 men without surgery in two centers in Brazil. Results: Our results showed that the continent group presented the urethral angle at rest significantly lower than the prostate group (p = 0.0002). We also observed that the incontinent group showed the displacement of the anterior bladder neck during contraction significantly lower than the continent group (p = 0.008). Conclusions:We found that the continent group presented the urethral angle at rest significantly lower than the prostate group. The incontinent group also showed the anterior bladder neck displacement during contraction significantly lower than the continent group. It was more evident when the severe incontinent group and the continent group were compared.
