项目摘要
A valved ventriculo-peritoneal shunt (V-P shunt) as a vesico-amniotic shunt (V-A shunt) preserves the filling/emptying cycle and normal bladder development in fetallambs with bladder outlet obstruction. We created obstructive uropathy in 60-day gestation fetal lambs.A V-A shunt was placed 3 weeks later,using a low-pressure (L:15-54 mm H2O) or a high-pressure (H:95-150 mm H2O) V-P shunt. We included non-shunted (O) and control (C) lambs. All were delivered at 130 days. Bladder volumes,bladder thickness, renal and bladder histology were compared. Five Group L (4 survived),four Group H (3 survived) and 5 Group O survived.Group H lambs had a dilated urachus,urinary ascites and severe ureteral dilatation similar to Group O lambs. There were 4 Group C lambs. Bladder volume was 10,15 and 1,150ml in Group H,115+-67.9 ml in Group L,128+-99.8 ml in Group O and 24.5+-3.84 ml in Group C.Low-pressure shunts preserved both bladder volume and renal development. High-pressure shunts did neither.
有瓣脑室-腹膜分流术(V-P分流术)作为膀胱-羊膜分流术(V-A分流术)可保留膀胱出口梗阻的胎儿的充血/排空周期和正常膀胱发育。我们在妊娠60天的胎羊羔中制造了梗阻性尿路病变。3周后放置V-A分流器,使用低压(L:15-54 mm H2O)或高压(H:95-150 mm H2O) V-P分流器。我们包括未分流(O)羔羊和对照(C)羔羊。所有小鼠均在130天分娩。比较膀胱体积、膀胱厚度、肾脏及膀胱组织学。L组5例(4例存活),H组4例(3例存活),O组5例存活。H组羔羊与O组羔羊相似,出现尿管扩张、尿腹水和严重输尿管扩张。C组羔羊4只。H组膀胱容量分别为10、15、1150ml, L组为115+-67.9 ml, O组为128+-99.8 ml, c组为24.5+-3.84 ml。高压分流也没有。
