约1.2％的子宫内膜异位症累及泌尿道,膀胱、输尿管和肾脏的比率40:5:1。1960年,搜集到151例泌尿道子宫内膜异位症,发现15例累及输尿管。至1980年已报告约100例输尿管子宫内膜异位症,且几乎完全异位于输尿管的下1/3段,仅1例位于骨盆缘以上。单侧病变远比双侧累及常见,双侧性发生在盆腔广泛子宫内膜异位症者,有人称之为“冰冻盆腔”综合征。发病机理最广泛接受的理论是(1)输卵管逆行排经致盆腔后种植,(2)淋巴及血管播散。另 About 1.2% of endometriosis involves urinary tract, bladder, ureter and kidney ratio 40: 5: 1. In 1960, 151 cases of urinary tract endometriosis were collected and 15 cases were found to involve the ureter. Approximately 100 cases of ureteral endometriosis have been reported by 1980 and almost exclusively in the lower 1/3 of the ureter, with only 1 case located above the pelvic margin. Unilateral lesion is more common than bilateral involvement, bilateral in the pelvic extensive endometriosis, some people call it “frozen pelvic” syndrome. The most widely accepted theory of pathogenesis is (1) pelvic retrograde tubal implantation, (2) lymph and vascular dissemination. another
