  1. 膀胱切开术 • 适应症 :膀胱结石、膀胱肿瘤。 • 1.保定与麻醉仰卧固定,全身麻醉。 • 2.术部 雌犬从耻骨前缘向前在腹白线上切开5-1o厘米,雄犬在阴茎侧方2-3厘米作腹中线的平行切口。

  2. 术式 • 切开皮肤、腹直肌与皮肤同方向切开达腹膜。外科镊子夹住腹膜切一小口,用组织钳把腹膜固定在腹直肌上,以防止腹膜滑脱,再继续切开腹膜与皮肤创同长,用创钩向左右拉开,手指伸入腹腔探查。膀胱内充满尿液时,易触及到膀胱体,膀胱空虚退到骨盆腔内,手指伸向骨盆腔,触到核桃大表面有皱壁的即为膀胱。将膀胱拉到创口。如尿充满时,用装有细针头的注射器,避开膀胱血管刺入膀胱尖吸出尿液,膀胱缩小后用组织钳固定膀胱尖并向上牵拉。避开或钳住膀胱壁血管,在膀胱尖切开

  3. 术后护理 • 术后注意观察排尿情况。如尿闭或排尿困难时,应及时查明原因,防止术部感染,连续应用抗菌素。如发现术部化脓,应及时拆线开放,不久切口可以自愈。
