Changes in bladder neck geometry and closure pressure after midurethral anchoring suggest a musculoelastic mechanism activates closure.

摘要: Aims The aim of this study was to investigate the anatomical origins and clinical significance cough pressure transmission ratio (CTR) by using virtual-operation (VO) techniques. Methods Thirty-four patients underwent perineal ultrasound examination, standard urethral testing both with without unilateral midurethral anchoring (VO), all tests being performed elevation. In eight where there no change in CTR, a one-sided fold suburethral vagina taken (pinch test) CTR repeated. Results After anchoring, maximal increased from mean 33.25 cm H2O 58.06 (P  100% proximal urethra observed 14 22 (P < 0.005), significant noted distal urethra. Further conversion six remaining plication test). Conclusions A musculoelastic closure mechanism most likely activates closure. is an index changed intraurethral area, not necessarily closure, may be more sensitive objective test than for diagnosing narrowing, especially when used techniques.
