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.

Vaginal delivery is commonly accepted as a risk factor in pelvic floor dysfunction; however, other obstetric procedures (episiotomy) are still controversial. In this work, to analyze the relationship between episiotomy and pelvic floor function, a finite element model of the pelvic cavity is used considering the pelvic floor muscles (PFMs) with damaged regions from spontaneous vaginal delivery and from deliveries with episiotomy. Common features assessed at screening of pelvic floor dysfunction are evaluated during numerical simulations of both Valsalva maneuver and contraction. As stated in literature, a weakening of the PFM, represented by damaged regions in the finite element model, would lead to a bladder neck hypermobility measured as a variation between the α angle (angle between the bladder neck and the symphysis pubis line and the midline of the symphysis) during straining and withholding. However, the present work does not associate bladder neck hypermobility to a more damaged muscle, suggesting that other supportive structures also play an important role in the stabilization of the pelvic organs. Furthermore, considering passive behavior of the PFM, independently of the amount of damage considered, the resultant displacements of the pelvic structures are the same. Regarding the PFM contraction, the less the muscle is damaged, the greater the movements of the pelvic organs. Furthermore, the internal organs of the female genital system are the most affected by the unhealthy of the PFM. Additionally, the present study shows that the muscle damage affects more the active muscle component than the passive.

This study assessed the feasibility of dynamic transperineal ultrasound (TPUS) pre/post-radical prostatectomy (RP). Ninety-eight patients were scanned preoperatively and at four time-points post-operatively. TPUS was performed in 98 patients using an abdominal transducer at rest, during pelvic floor contraction (PFC) and Valsalva (VS) maneuver in supine and standing positions. Urodynamic evaluations included bladder neck angle at rest/PFC/VS, and degree of bladder neck movement. Pre-operative and post-operative measurements were technically feasible in >85% (supine) and >90% (standing) of patients. TPUS offers a reliable non-invasive dynamic assessment of the pelvic floor post-prostatectomy and may prove a useful adjunct for guiding exercises to preserve continence.
