自1983年8月～1993年8月,我院共收治输尿管断裂或狭窄16例,前6例采用普通横断对端吻合法治疗,失败2例;后10例采用自行设计的斜“Z”形吻合法治疗,无一例失败.现将斜“Z”形吻合法介绍如下.本法的操作步骤为:找到输尿管断端或狭窄段后,充分游离输尿管,将两输尿管断端剪成斜形,用眼科剪将两断端矢状面纵行由中间劈开0.5～0.6cm,分成长短两个瓣,和斜行的断面相平行剪去其中的短瓣,另一端作相同处理.将两个保留的长瓣对合,先用4-0肠线全层缝合两侧面,每侧1针,然后用5-0无损伤线吻合,先缝4个角,后缝合各边,缝线不穿透粘膜(见附图).
From August 1983 to August 1993, a total of 16 cases of ureteral rupture or stenosis were treated in our hospital. The first 6 cases were treated with common transection and end-to-end anastomosis, and 2 cases failed. The latter 10 cases were designed with diagonal “Z” Anastomosis treatment, without a case of failure now oblique “Z” -shaped anastomosis introduced as follows: The steps of this method: to find the ureteral stump or stenosis, the full free ureter, the ureter ends cut into a beveled, Use the eye scissors to split the two ends sagittal longitudinal cleft 0.5 ~ 0.6cm from the middle, divided into short and long two petals, and the oblique line parallel to cut off one of the short flap, the other end for the same treatment will be the two Retained long flap pairs, the first full-thickness suture with both sides of the 4-0 catgut on both sides, each side of a needle, and then with a 5-0 non-destructive line anastomosis, the first seam 4 corners, after suture the sides, the suture does not wear Transmucosal (see attached).
