摘要
目的探讨三维动态超声诊断盆底失弛缓综合征（PFD）的可行性。方法对符合PFD诊断的30例女性便秘患者行三维动态超声检查，比较其静息状态下与模拟排粪状态（Valsalva动作）时经会阴动态超声测量的指标饯角、经肛管三维超声测量的β角、γ角和H线的差异；同时，对超声各测量指标诊断盆底失弛缓综合征的检出率进行分析。结果三维动态超声检测出30例患者中直肠前突13例（43．3％），直肠黏膜内套叠14例（46．7％），子宫脱垂11例（36．7％），膀胱脱垂1例（3．3％）。与静息状态相比，Valsalva动作时α角、β角和H线显著缩小，γ角显著增大，差异均有统计学意义（均P〈0．01）。α角、β角、γ角和H线对PFD的检出率分别是93．3％（28／30）、96．7％（29／30）、96．7％（29／30）和86．7％（26／30）。结论经会阴超声测量的仅角和经肛管超声测量的β角、γ角和H线都可以为临床上诊断PFD提供可行的指标数据。
Objective To explore the feasibility of dynamic three-dimensional ultrasound measurement in the diagnosis of pelvic floor dyssynergia （PFD）. Methods Thirty female patients with PFD received dynamic three-dimensional ultrasound. The differences in angle α measured by transperineal three-dimensional ultrasound, and angle β, angle γ, and H line as measured by transanorectal three-dimensional ultrasound were compared between resting state and Valsalva maneuver. In addition, the detective rate of PFD by different parameters was analyzed. Results In 30 patients, rectocele was found in 13 cases（43.3%）, rectal internal mucous intussusception in 14 cases（46.7%）, uterine prolapse in 11 cases（36.7%）, and bladder prolapse in 1 case（3.3%）. Compared with the resting state, α, β and H decreased obviously, but γ increased apparently in Valsalva maneuver, and differences of these parameters were statistically significant（all P〈0.01）. Detective rates of PFD for parameters of α, β, γ and H were 93.3%（28/30）, 96.7%（29/30）, 96.7%（29/30） and 86.7% （26/30）, respectively. Conclusion Measurements of α, β,γ and H can provide feasible indicators for clinical diagnosis of PFD.
