METHODS : ① Cystourethrography : Patient 's posterior urethrovesical angle was determined and considered as normal if it was < 100 ° and abnormal if > 100 ° .

方法：①膀胱尿道造影：测定患者 膀胱 尿道后角：<100°判定为正常，>100°判定为异常。

Type ⅱ: refers to posterior urethrovesical angle vanished with urethral tilt angle > 45 ° and the biggest urethra closure pressure < 20 cmH2O ;

Ⅱ型： 膀胱尿道后角消失，尿道倾斜角>45°，最大尿道关闭压 >20cmH2O；

Major complications ( 4 % ) included urethrovesical leak requiring re-operation post-operative cerebrovascular accident and transient ureteric obstruction .
