自1986年10月以来采用带蒂腹膜瓣和脂肪组织治疗输尿管长段狭窄7例,效果满意。一般资料 7例中男4例,女3例,年龄37～58岁。左侧输尿管上段狭窄2例,下段、右侧上段各1例,中段3例。狭窄段长1.5～4.7cm。病程7月～4.5年。均有不同程度肾功能损害。手术方法游离狭窄段输尿管,并将其前壁纵行全层切开至正常段两端约0.5cm处,在邻近之腹膜上由近向远切取带蒂腹膜瓣,其长度比狭窄段输尿管长约1.5cm,宽度视缺损宽度再增加0.3cm左右,浆膜面与输尿管切开面对合,上中段缝合前先放入硅胶管作支架管,直径比输尿管直径略小0.1cm,再用5—0肠线间断缝合,支架管经肾或肾盂造瘘口引出;下段狭窄,则在其近端约5cm处及经膀胱前壁用“T”管和硅胶管分别作尿液转流和支架引流。最后以邻近带蒂脂肪组织复盖包裹整形段
Since October 1986, pedicled peritoneal flap and adipose tissue were used to treat 7 cases of long ureteral stenosis with satisfactory results. General information in 7 cases, 4 males and 3 females, aged 37 to 58 years. The left upper ureteral stenosis in 2 cases, the lower section, the right upper section in 1 case, the middle section in 3 cases. Narrow section length 1.5 ~ 4.7cm. Duration of July ~ 4.5 years. Have varying degrees of renal dysfunction. Surgical methods free stenosis ureter, and its longitudinal anterior longitudinal cleft layer full-thickness incision to about 0.5cm at both ends of the normal, in the adjacent peritoneum from proximal to distal removal of the pedicle peritoneal flap, the length of the ureter length than the narrow segment About 1.5cm, depending on the width of the width of the defect to increase about 0.3cm, serosal surface and ureter incision confrontation, before the middle of the suture into the silicone tube for stent tube diameter slightly smaller than the ureter diameter 0.1cm, and then 5 -0 intestine interrupted suture, the stent tube leads to the kidney or pyelography; lower stenosis, then at about 5cm proximal and through the anterior bladder wall with “T” tube and silicone tube for urinary diversion and stent drainage. Finally, adjacent to pedicle fatty tissue wrapped plastic wrap
