【摘要】 目的 :研究前列腺移行区体积 ( TV)及移行区指数 ( TZI)对膀胱出口梗阻 ( BOO)的诊断价值。方法 :选入 6 3例前列腺增生症 ( BPH)患者 ,将直肠 B超结果与压力 -流率测定结果进行比较。结果 :当 TZI>0 .4时 ,诊断BOO的敏感性 ( 76 .9% )及特异性 ( 10 0 % )最好 ;当 TZI<0 .3时 ,诊断无 BOO的敏感性与 TV<10 cm3相同( 72 .7% ) ,但 TZI的特异性 ( 5 3.3% )较 TV的特异性 ( 44 .4% )稍好 ;当 TZI处于 0 .3～ 0 .4时 ,如 TV>15 cm3或有前列腺突入膀胱时 ,应视为 BOO可能存在。结论 :TV及 TZI可以作为尿动力学检查之外的诊断 BOO的补充方法 ,但不能代替尿动力学检查更多还原

【Abstract】 Purpose:To study the clinic value of transition zone volume(TV) and transition zone index(TZI) in patients with benign prostatic hyperplasia. Methods:We compare TRUS datum with urodynamic datum in 63 cases with BPH. Results:When TZI is more than 0.4, sensibility and specificity of patients with BOO is 76.9 % and 100%; when TZI is less than 0.3, or TV is less 10 cm3, sensibility of patients with no BOO is 72.7%, but the former specificity (53.3%) is better, when TZI ranges from 0.3 to 0.4 ,and if TV is more than 15 cm3 or prostate protrude into the bladder, the patient may be diagnosed as BOO.Conclusions:TV and TZI is one means of diagnosing patients with BPH as BOO in addition to urodynamic test, but not replace it.更多还原
