14 cases of ureteric obstruction in patients with uterine prolapse are presented. The clinical, radiological, endoscopic and surgical observations are considered and discussed. Ureteric dilatation develops in two successive stages each of which has a different mechanism. In the first stage, stretching of the terminal ureter leads to a fusiform and gradual dilatation. In the second more advanced stage, caudal and posterior displacement of the trigone and bladder base leads to a rotation of the intramural ureter forming a sharp angle with the juxtavesical ureter, causing further ureteric obstruction. These observations emphasize the importance of urographical evaluation in patients with uterine prolapse.
本文报告了14例子宫脱垂患者输尿管梗阻的病例。对其临床、放射学、内镜及手术观察结果进行了分析和讨论。输尿管扩张分两个连续阶段发生，每个阶段的机制不同。第一阶段，输尿管末端受牵拉导致梭形且逐渐扩张。在第二阶段即更晚期，膀胱三角区和膀胱底部向尾侧和后方移位，导致壁内段输尿管旋转，与膀胱旁输尿管形成锐角，造成进一步的输尿管梗阻。这些观察结果强调了子宫脱垂患者进行尿路造影评估的重要性。
