位于膀胱三角区和尿道内口附近的巨大膀胱憩室,由于其特殊的部位和毗邻,与输尿管、尿道、输精管、精囊腺、前列腺、直肠及膀胱血管、闭孔血管和肛提肌关系密切,女性可与阴道、宫颈相邻近,再加上经常出现的憩室炎、憩室内结石,手术部位深,手术视野小,操作受限制,常常使手术切除憩室十分困难,易致副损伤、大出血等。近来来,我们对这类膀胱憩室采用了憩室颈部外膜下缝扎术,取得了良好效果。现将其方法介绍如下。 1.平卧位,常规切开膀胱前壁,吸尽尿液,显示膀胱三角及憩室口。 2.用探针探查憩室深度,前后左右径长度, The bladder diverticulum, located in the trigone and near the internal urethra, is closely related to the ureter, urethra, vas deferens, seminal vesicle, prostate, rectum, and bladder vessels, obturator vessels and levator ani due to its specific location and proximity, Adjacent to the vagina and cervix, coupled with frequent diverticulitis, diverticula stones, deep surgical site, small operative field of view, limited operation, often make it very difficult to remove the diverticulum surgery, easy to cause side injury, bleeding and so on. In recent years, we have adopted diverticulum subepithelial suture of this diverticulum and achieved good results. Now the method described below. 1. Supine position, routine incision of the anterior wall of the bladder, exhaustion of urine, showing the bladder trigone and diverticular orifice. Probe the depth of diverticulum, before and after the left and right path length,
